Which nonsteroidal antiinflammatory drug should be used

If the patient can take oral medication, an oral agent should be used. Most oral agents have the same degree of analgesia as antiinflammatory activity. The degree of potency of analgesia parallels the risk of gastric upset with oral agents. One or two specific agents may work better for a given patient, but their identification is usually a matter of trial and error. Price also may be a factor. Older, off-patent NSAIDs may be significantly cheaper and just as effective (e.g., naproxen, indomethacin, and ibuprofen). For patients who cannot take oral medication, parenteral ketorolac is the available option. Ketorolac has a more potent analgesic than antiinflammatory effect. It may be given intravenously or intramuscularly. In patients over 65 years old who weigh less than 100 pounds or who are frail, half of the regular dose should be used. In patients with a serum creatinine above 1.3 ml dl, alternatives to the use of ketorolac should be considered. The side effects of NSAIDs may be...

Nepafenac Antiinflammatory [5255

Nepafenac, launched last year by Alcon Laboratories, is a topical ophthalmic medication indicated for the treatment of ocular pain and inflammation associated with cataract surgery. Nepafenac is a prodrug of amfenac, which is an NSAID and a potent non-selective inhibitor of COX-1 (IC50 0.25 mM)) and COX-2 (IC50 0.15 mM). Nepefenac itself exhibits only weak activity against COX-1 (IC50 64.3 mM). Amfenac (Fenazox) has been marketed in Japan since 1986 for the treatment of rheumatoid arthritis, post-surgical pain, and inflammation. With most NSAIDs that are currently being used as topical ophthalmic agents, the maximum drug concentration is achieved on the ocular surface, with progressively lower concentrations in the cornea, aqueous humor, vitreous, and retina. Ne-pafenac has been found to have a penetration coefficient that is 4 - 28 times greater than that achieved with conventional NSAIDs such as diclofenac, bromofenac, and ketorolac. In addition, the bioconversion of nepefenac to...

Lumiracoxib Antiinflammatory [4851

As a second-generation, selective cyclooxygenase (COX-2) inhibitor, lumiracoxib is devoid of the gastrointestinal issues that plague other non-selective, non-steroidal, anti-inflammatory drugs (NSAIDs) that crossover to COX-1. As an inhibitor of the inducible COX-2 that is up-regulated in pathological processes of pain and inflammation, lumiracoxib blocks the conversion of arachidonic acid to prostaglandins, the mediators of the pathological effects. It's mode of binding to COX-2 has been found to differ from the other selective COX-2 inhibitors the carboxylic acid forms hydrogen bonds with Tyr-385 and Ser-530 in the catalytic site rather than seeking interactions within the larger hydrophobic side pocket. In human whole blood, lumiracoxib displays an IC50 value of 0.13 mM for COX-2 versus 67 mM for COX-1, resulting in a selectivity ratio of 515. Regarding its synthesis, lumiracoxib may be prepared by a couple of routes. While the construction of the diarylamine core via a...

Management options

Oedema recent evidence suggests that calcium-channel blockers such as nifedipine may be at least equally effective with a better safety profile. In general, probably the fewer drugs used overall the better. Certain drugs given near to delivery may cross the placenta and affect the fetus, e.g. non-steroidal antiinflammatory drugs (which can prevent the ductus arteriosus from closing).

The RICE Routine for Athletic Injuries

You can take an over-the-counter painkiller such as aspirin, acetaminophen, or ibupro-fen. Aspirin and ibuprofen also help reduce inflammation. After 1 or 2 days of RICE, begin gently stretching the affected area. Don't stretch to the point at which it becomes painful, or you could damage the muscle again. Your doctor or a physical therapist can recommend simple exercises tailored to the specific injury to help you regain strength.

Secretase Inhibitors as Therapeutics for Alzheimers Disease

Alzheimer's disease is defined by the co-occurrence of two histologic lesions in brain - extracellular deposits (senile plaques) whose principal component is a fibrillar form of a predominantly 40-42 amino acid peptide known as p-amyloid (AP), and intracellular tangles of a hyperphosphorylated form of the microtubule associated protein tau. Tau dysfunction appears to have a role in the neurodegeneration of Alzheimer's disease (9,10). However, considerable evidence points to a causative role for the accumulation of A(3 peptide, potentially related to the neurotoxicity shown by Ap in in vitro and in vivo models (11). A variety of approaches towards mitigating the impact of Ap on the brain have been pursued, including inhibition of Ap production, the use of antiinflammatory agents (12,13), inhibition of Ap aggregation (14), and immunization against Ap (15,16). Therapeutic strategies aimed at reducing amyloid production and aggregation have been reviewed recently in this series (17,18)....

Adiponectin as a potential therapeutic target

As discussed above, promising results obtained from numerous animal experiments and human epidemiological studies support the role of adiponectin as a potential drug target for developing novel therapeutics against a panel of obesity-related chronic diseases. However, adiponectin is an abundant plasma protein (5-30 p.g mL). The production of recombinant adiponectin is also challenging because of the complex tertiary and quaternary structure of the protein and the distinct activities of the different isoforms. Direct supplementation of recombinant adiponectin in human subjects would be extremely expensive. An alternative approach is to use pharmacological or dietary intervention to increase the suppressed endogenous adiponectin production in obesity, or to enhance adiponectin actions in its target tissues. In this respect, it is interesting to note that the PPARy agonists thiazolidinediones (TZDs), such as rosiglitazone and pioglita-zone, which increase adiponectin production in both...

Modulators Of ySecretase

In 2001, a subset of nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen (54), indomethacin (55), and sulindac sulfide (56), were found to reduce cellular secretion of Ap42 116 . Importantly, the reduction in Ap42 levels was determined to be independent of cyclooxygenase (COX) activity. Mass spectrometry experiments revealed that the decrease in Ap42 was accompanied by a dose-dependent increase in the production of Ap38 116 . Shorter Ap species are reportedly less toxic to cells than Ap40 and Ap42, and inhibit Ap42 aggregation 117 . Subsequent radiolabeling experiments 73 and fluorescence resonance energy studies 118 have suggested that these particular NSAIDs bind to an allosteric site on the presenilin subunit of the g-secretase complex, and induce a change in the enzyme conformation which favors the production of smaller, nonamyloidogenic Ap peptide fragments. Interestingly, it has been demonstrated that Ap42 lowering NSAIDs also modulate the cleavage pattern of the...

How can you identify a patient at risk for bleeding

Preoperative evaluation includes history, physical examination, and performance of appropriate laboratory tests. Questions about bleeding disorders and problems (e.g., tendency to form large hematomas after minor trauma, severe bleeding while brushing teeth) and bleeding after previous surgical procedures (e.g., dental extractions, tonsillectomy) are important. Prior surgery without transfusion suggests the absence of an inherited coagulation disorder. Review of medications is necessary to identify medications with anticoagulant potential (e.g., nonsteroidal antiinflammatory drugs NSAIDs , antiplatelet drugs, and anticoagulants). Coagulation studies may confirm a clinical suspicion that the patient has a bleeding disorder. No evidence supports the value of preoperative coagulation studies in asymptomatic patients.

NSAIDs and NSAIDlike compounds as modulators

Human epidemiological studies support a decreased risk of developing AD with long-term NSAID usage 124,125 . However, it is unclear whether the decreased risk can be attributed to the known anti-inflammatory properties of these agents or their recently discovered g-secretase modulator activity. In cells, IC5o values for the inhibition of Ap42 secretion by 54, 55, and 56 range from 25 to 250 p.M 116 . In transgenic mice, doses of 50 mg kg day of these same three NSAID modulators have been reported to effect 30-39 reductions in brain Ap42 116,126 . It should be noted that not all research groups have been able to replicate these results and one group has reported complications with dose limiting toxicity 127 . Certain NSAIDS have also been reported to elevate brain Ap42 levels by 20-80 in mouse models 126-129 . Recent studies with NSAID-like modulators have focused on developing compounds with reduced COX activity. Clinical evaluation of the (R)-enantiomer of the NSAID flurbiprofen is...

Box 33 Immune Modulators and Fungal Infections

The immune system is powerful, and sometimes it goes astray. For example, rheumatoid arthritis, a painful swelling of joints, involves the excessive action of tumor necrosis factor-a an important protein component of the immune system. Anti-inflammatory agents, such as corticosteroids, relieve the symptoms of arthritis. But they also weaken the defense against fungi. Because the current medicines never actually cure arthritis, they must be taken for life. That makes fungal infection a constant threat.

Regulatory Th cells as key players in the control of chronic neuroinflammation

Although little is known about the progeny of the numerous CD4+CD25+FoxP3+ Treg cells accumulating in the inflamed CNS, both expansion of nTreg and de novo differentiation generally seem possible (Kretschmer et al., 2005 Papiernik et al., 1998). As FoxP3 is inducible upon transgenic TGF-p-overexpression in vitro, the hypothesis has been formed that TGF-p production might be responsible for successful Treg induction from naive CD4 precursors, as well as its expansion and maintenance. This correlates well with in vivo findings, showing that TGF-p induces antigen-specific CD4+CD25+FoxP3+ Treg expansion (Peng et al., 2004). Indeed, transfer of in vitro generated MOG-specific and TGF-p-producing CD4+ cells protected recipients from clinical symptoms in actively induced MOG-EAE in C57BL 6 (Carrier et al., 2007), and TGF-p-neutrali-zation abolished remission in active EAE in the SJL J strain (Zhang et al., 2006). One recent in vitro coculture study suggests that neurons, in their cross talk...

Beta Interferon Therapies Avonex Betaseron and Rebif 711 Efficacy

A variety of action mechanisms have been reported, including inhibition of T-cell co-stimulation and or activation processes, modulation of anti-inflammatory and pro-inflammatory cytokines, inhibition of interferon gamma-induced class-II expression, inhibition of antigen presentation, and reduction in aberrant T-cell migration. IFNPs are administered either by subcutaneous injection (Betaseron and Rebif) or by intramuscular injection (Avonex). Injection site reactions usually subside within weeks. Management includes icing and rotation of site, topical application of anesthetics or corticosteroid, improved injection technique, and warming the medication or using autoinjectors. Flu-like symptoms are common dose titration, nonsteroidal anti-inflammatory drugs (NSAIDS) or acetaminophen may be helpful, though symptoms usually resolve by 3 months 70 . Symptoms occur within a few hours of each injection and last 12-24 h. Injections should be administered at night. Hematologic and hepatic...

Bronchial Hyperresponsiveness

One of the absolute features of asthma is exaggerated nonspecific airway reactivity to a variety of irritating stimuli. Thus, asthmatics develop airway obstruction in response to natural exposures (cold air, exercise, irritating chemicals, laughing, and coughing) or to provocations in the laboratory (histamine, methacholine, cold air hyperventilation) (Table 9). Airway hyperresponsiveness is found universally in asthmatics, in a portion of subjects with chronic bronchitis, in some subjects with allergic rhinitis, and in 3-8 of otherwise normal subjects. There is a close correlation between the degree of increased responsiveness and disease severity patients with the most reactive airways often require oral CCSs for control, whereas milder degrees of abnormality predict the requirement for fewer medications. Hyperresponsiveness increases after allergen exposure, late-phase allergic reactions, viral infections (especially influenza-type infections), and ozone exposure. Conversely,...

Pathogenesis Of Nsaid Toxicity Ulceration

COX-1 is constitutively expressed in the GI tract and plays an important role in the maintenance of normal gastric and duodenal physiology. COX-2 is an inducible form, which is upregulated in areas of injury (10). However, COX-2 is also regulated in response to physiologic stimuli in numerous tissues, including the kidney, brain, and reproductive tract. NSAIDs, in general, nonspecifically inhibit COX isoforms, leading to both beneficial (antiinflammatory) and toxic (GI bleeding) outcomes. Finally, acid plays an important secondary role in NSAID-induced ulceration. Recent data demonstrating the efficacy of high-dose H2 blockers and proton pump inhibitors in the treatment and prevention of NSAID damage support this concept. This suggests that topical injury is the first step in NSAID ulceration then acid, in concert with prostaglandin depletion, synergizes for the development of clinically important ulceration. Finally, the discovery of two distinct COX isoforms has further...

Clinical Box 11 Why Doesnt Your Stomach Digest Itself

The weakening of these mucosal defense mechanisms results in ulcerations and eventually gastric ulcer disease. A variety of factors including excessive alcohol and tobacco consumption, stress, and nonsteroidal anti-inflammatory drugs such as aspirin can lead to erosion in the lining of the stomach. Additionally, there is also a positive correlation between Helicobacter pylori (H. pylori) bacterial infection and the incidence of gastric and ulcers of the small intestine. H. pylori produces large quantities of the enzyme urease, which hydrolyzes urea to produce ammonia. The ammonia neutralizes the gastric acid in the bacteria's immediate environment thus protecting the bacteria from the toxic effects of its normally toxic acid environment. It is remarkable how some cells find a way to survive even in the deadliest environment.

Phosphodiesterase 4 Inhibitors

PDE4 is the predominant isozyme present in inflammatory cells and selective PDE4 inhibitors are a popular target for novel anti-inflammatory drugs (6). The distribution of PDE4 in inflammatory cells and airway smooth muscle, and the effects of selective PDE4 inhibitors in vitro, have been comprehensively reviewed (7,8). The therapeutic potential of PDE4 inhibitors in a variety of diseases has been reviewed recently (8,9). First generation PDE4 inhibitors, typified by rolipram, suffered from dose-limiting side effects including nausea, emesis and gastrointestinal disturbances, which severely restricted their therapeutic utility. Second generation compounds such as Ariflo have been identified with reduced side effect liability, and the clinical development of such compounds has been reviewed recently (10). Two strategies for minimizing side effects have been pursued selectivity for the catalytic site over the high affinity rolipram binding site (HPDE) and selectivity for a specific PDE4...

Allergen Immunotherapy

1 Topical nasal azelastine when symptomatic or sodium cromoglycate to eyes, nose, or both alternative for intermittent eye symptoms is topical ocular antihistamine or topical nonsteroidal antiinflammatory (ketoroloac tromethamine )b 1 Intranasal corticosteroid and topical eye therapy with sodium cromoglycate or lodoxamide tromethamine or olopatadine hydrocholoride topical nonsteroidal antiinflammatory (ketoroloac tromethamine) additional therapy for exacerbationsb

Small Molecule Inhibitors Of Gsk3 31 Natural product derived GSK3 inhibitors

Derivatives of the naturally occurring GSK-3 inhibitor hymenialdisine, 1, such as indoloazepine 2, were studied as anti-inflammatory agents through inhibition of the NF-kB pathway 53 , Compound 2, which inhibited GSK-3 (IC50 0.15 mM) in addition to CDK-1, MEK-1, CHK-1, and CHK-2 with IC50

Kinins And Their Receptors

Kinin peptides are released by the proteolytic cleavage of kininogen by either plasma kallikrein or tissue kallikrein (8-9). Kallikreins are inactive zymogens until activated either by autoproteolysis or the action of a number of other proteases. Mutations in plasma kallikrein, encoded by the KLKB1 gene, result in Fletcher factor deficiency that has a similar phenotype to Flaujeac deficiency, a prolonged activated partial thromboplastin time, with no overt symptoms (OMIM 22900). Until recently, there were only three kallikrein genes identified in humans. However, sequencing of the region on human chromosome 19 that contains the tissue kallikrein gene revealed that it is part of a gene cluster that contains at least 15 members a similar cluster containing 25 kallikrein genes is present on mouse chromosome 7. Since the substrate specificity of the recently identified members of the kallikrein family are not established and it is possible that other proteases act on kininogen, the...

Inflammation and Immune Effector Heterogeneity in MS 231 T and B Lymphocytes

Exert both beneficial and detrimental effects on lesion evolution 16, 88 and are subclassified into two phenotypes. The Ml phenotype produces pro-inflammatory mediators and reactive oxygen species (ROSj 42, 65 and is predominantly involved in Thl cell responses. The M2 phenotype, on the other hand, produces anti-inflammatory mediators and is associated with Th2 responses, tissue scavenging, tissue remodeling, and repair and resolution of inflammation 66 . Additionally, M2-induced signals inhibit Ml-induced chemokines 65, 66 . Active MS lesions contain numerous foamy macrophages, reflecting ingestion and accumulation of myelin lip-ids. A recent MS immunocytochemical in vitro study suggested that the foamy macrophages found at the MS plaque edge is mainly involved in myelin phagocytosis, whereas those located in the plaque center demonstrate an M2 phenotype and may, therefore, contribute to the resolution of inflammation, limit further lesion development, and promote tissue repair 16 ....

The Prospects for Microbial Genomics Providing Novel Exploitable Antibacterial Targets

Introduction - Antibiotics have been a major triumph in applied medical science since their introduction in the last century. The rapid improvement of patients afflicted with heretofore deadly infections led to these compounds being termed miracle drugs . Unfortunately, it has become increasingly clear that bacterial resistance to these compounds is rising at a rate that threatens to undermine their future utility (1,2). In this sense, antimicrobials stand in a somewhat unique position among drug classes. Compounds that affect human physiology, such as lipid-lowering agents, ACE inhibitors, and anti-inflammatory agents, do not engender resistance to their pharmacological targets in the human population. However, in the case of infectious agents we are dealing with rapidly evolving populations of organisms placed under selective pressure by antibiotics (3). Exacerbating the situation is the fact that many of the existing antimicrobial classes are derived from natural products, and...

Hydroxytrifluoromethylphenylpentanoic Htpp Aryl Amides

Evidence that a dissociated GR agonist can convincingly demonstrate good in vivo anti-inflammatory activity while achieving a better safety profile compared to a steroid is supplied by ZK-216348 ((+)-enantiomer, 13) 24,25 . This compound, although partially selective over other nuclear receptors, shows good activity in TR assays (TNFa inhibition in hPBMC IC50 90 nM, 63 efficacy interleukin 8 (IL-8) inhibition in THP-1 cells IC50 35 nM, 52 efficacy) and is less active in a TA assay (TAT induction in liver hepatoma cells EC50 95 nM, 88 efficacy). When administered topically in the croton oil model of ear inflammation in mice, compound 13 produces an ED50 of 0.02 mg cm2. A superior safety profile (e.g., glucose levels, spleen involution and skin atrophy), compared to prednisolone, is also observed. However, similar adrenocorticotropic hormone suppression as prednisolone is seen implying that some steroid-induced side effects may be mediated through the TR pathway. The disclosure of 13...

DIHYDRO1Hbenzopyrano[34fQuinolines Dbq

The dihydro-1H-benzopyrano 3,4-f quinolines (DBQ) scaffold has received considerable drug discovery attention aimed at developing versatile hormone receptor ligands. An advanced compound in this class, AL-438 (34), was the first dissociated GR agonist to show a spectrum of in vivo anti-inflammatory activity while attenuating the side effect profile 44 . Briefly, 34 is a potent and selective GR ligand (GR Ki 2.5 nM) exhibiting cellular dissociative behavior in TR (IL-6 inhibition in human skin fibroblast) compared to TA (TAT in HepG2 cells, osteocalcin inhibition in MG63 cells and aromatase induction in HSF cells) assays. In addition, 34 displays steroid-like anti-inflammatory activity in vivo (rat carrageenan-paw edema (CPE) ED50 11 mg kg rat adjuvant-induced arthritis (AIA) ED50 9 mg kg). Reduced side effects (bone metabolism and glucose regulation) in rats are seen with 34 when compared with prednisolone at equivalent anti-inflammatory doses. Further SAR studies of 34 reveal that...

Other Lipoprotein Mediators

Vascular Protectants - The compound AGI-1067, 30, has been reported to inhibit atherosclerosis in apo E and LDL receptor knockout mice (61, 62). AGI-1067 is an anti-inflammatory, lipid-lowering compound, that has been shown to selectively inhibit cytokine induced vascular cell adhesion molecule 1 (VCAM-1) and monocyte chemotactic protein 1 (MCP-1) expression in vitro and in vivo. AGI-1067 lowers plasma cholesterol levels in cholesterol-fed mice and apo E knockout mice. In LDL receptor knockout mice, AGI-1067 inhibited atherosclerosis without lowering plasma cholesterol levels. These results indicate that AGI-1067 lowers plasma cholesterol through enhanced LDL receptor mediated lipoprotein clearance and that this compound has a direct anti-atherosclerosis vascular protectant activity. AGI-1067 has progressed to clinical trials and may be

Polyphenols and activated NFkB

Activation.6,25 Consistently, experimental data are accumulating regarding polyphenolic compounds as natural phytochemical antioxidants that possess anti-inflammatory properties by downregulating NF-kB. Some of the most relevant findings about this aspect are summarised in Table 5.1. The cell-to-cell interaction following the expression of adhesion molecules (ICAM-1, VCAM-1 and selectin) in endothelial cells induced by cytokines treatment has been reported to be blocked by hydroflavones and flavanols.39 Apigenin, the most potent flavone tested in this study, inhibited the expression of adhesion molecules, the expression of both interleukin-6 and interleukin-8 induced by TNF-a and interleukin-1-induced prosta-glandin synthesis. Apigenin was found to have no effect on the nuclear translocation of NF-kB, but significantly inhibited the expression of the reporter gene b-galactosidase driven by NF-kB elements in SW480 cells induced by TNF-a, suggesting that NF-kB transcriptional activation...

Emerging Opportunities for the Treatment of Inflammatory Bowel Disease

Many hypotheses have been developed to explain the underlying disease pathophysiology of IBD. The observation that patients have increased mucosal permeability which may lead to chronically-enhanced immune responses to enteric bacterial antigens and abrogated self-tolerance is common amongst them. This commensal relationship between gut pathogens and IBD is also reflected by the transient improvement observed in CD patients when given antibiotic probiotic therapy. Mutations of one gene in particular, NOD2, appear to be responsible for the exacerbated inflammatory responses to enteric bacteria in some individuals (3, 4). NOD2 serves as an intracellular receptor for bacterial lipopolysaccharide and is linked to the activation of the transcription factor, NF-kB. However, only approximately one fifth of CD cases can be attributed to the NOD2 mutation and there does not appear to be any linkage between mutations in the NOD2 gene and UC. As a target cluster, the NF-kB pathway has long been...

Firstline Pharmacotherapy

The founding member of the 5-aminosalicylate drugs, 5-ASA's, was sulfasalazine, a chemical combination of sulfapyridine and 5-ASA. These agents (eg. mesalazine and olsalazine) are first-line therapy for the treatment of patients with mild to moderate UC and CD, and as a maintenance therapy to prevent disease relapse in UC. For disease in the distal bowel, multiple delayed- and sustained-release formulations, as well as pro-drugs such as olsalazine, have been designed to release the majority of an oral dose directly in the distal ileum colon, thus preventing topical exposure in the proximal small intestine. The most recently introduced pro-drug, balsalazide (1) contains azo bonds that are cleaved by colonic bacterial azo-reductases and release the active 5-ASA, mesalazine, locally. For rectal disease, rectal foams are also administered. The mechanism by which the 5-ASA's exert their anti-inflammatory activity appears to be, in part, by inhibiting the activation of NF-kB (5).

Classification And Etiological Considerations

In certain individuals, urticaria and angioedema are the result of agents that alter the metabolism of arachidonic acid. The occurrence of hives and angioedema is of an acute nature and is often self-limiting. Once again, this interaction occurs in the absence of a specific response with the involvement of IgE. Therapeutic agents included in this category are aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). Rarely, these responses to NSAIDs can be fulminant and life-threatening.

Targeting Lymphocyte Recruitment To The Inflamed Bowel

A4B7 MAdCAM - A specific system whereby lineages of lymphocytes bearing the expression of the a4p7 integrin were able to specifically home to the gut by engaging the mucosal addressin, MAdCAM has been described (89). MAdCAM is uniquely expressed on high endothelial venules supporting on the gut lamina propria and associated lymphoid tissue. The expression of MAdCAM increases tremendously at sites of inflammation, leading to an elevation in the recruitment of a4 37+ lymphocytes (90). Blocking anti-MAdCAM or anti-a4p7 antibodies are effective at blocking the rolling and adhesion of lymphocytes to the gut endothelium and reduce inflammation in animal models of colitis (13, 91). Humanised monoclonal antibodies natalizumab and LDP-02 that block the a4p7 MAdCAM interaction are in clinical development for UC and CD (Table 1). By inhibiting the recruitment of key inflammatory cells these agents have the potential to improve IBD symptoms and re-balance oral tolerance without inducing systemic...

Matrix Metalloproteinases Inhibitors

Doxycycline inhibits MMP activity at sub-antimicrobial doses 90 and is the only MMP inhibitor widely available clinically, indicated for the treatment of periodontal disease 91 . Prescribed as an antibiotic, doxycycline is also used clinically to manage COPD. In August 2007, a clinical trial for the macrolide antibiotic azithromycin commenced to study its anti-inflammatory properties in people with COPD through the inhibition of the MMP-catalyzed breakdown of collagen 92 . Broad spectrum MMP inhibitors, such as marimastat (BB-2516), have performed poorly in clinical trials. Marimastat was shown to have considerable side effects and dose-limiting musculoskeletal toxicity. The mechanism of this toxicity has not been completely elucidated, though several proposals have been advanced 93 .

History And Physical Examination

History and physical examination may sometimes provide clues to the cause of obscure GI bleeding. A directed history can reveal the use of medications known to cause mucosal damage or exacerbate bleeding nonsteroidal antiinflammatory drugs (NSAIDs), alendronate, potassium chloride, and anticoagulants . A family history of GI blood loss will expand the differential diagnosis to include hereditary hemorrhagic telangiectasia, blue rubber bleb nevus syndrome, and intestinal poly-posis. Typical lesions can be found on the upper extremities, lips, and oral mucosa in patients with hereditary hemorrhagic telangiectasia. Patients with blue rubber bleb nevus syndrome can have cutaneous hemangiomas in addition to those in the GI tract. Some rare causes with typical findings on physical examination include celiac sprue (dermatitis herpetiformis), AIDS (Kaposi's sarcoma), Plummer-Vinson syndrome (brittle, spoon-shaped nails, atrophic tongue), pseudoxanthoma elasticum (chicken-skin appearance,...

Monocyclic corebased CB2 agonists 311 Sixmembered aromatic cores

Its ZIPI model efficacy confirmed an anti-inflammatory activity at CB2 28,29 . Structure-activity relationship studies of a closely related genus of sulfamoyl benzamides have also been reported 32 , wherein, 12 (R1 CH3) is described as the preferred compound in this series (hCB2 hCB1 EC50 4nM 8.9 mM in the adenylate cyclase assay) 33 . The desmethyl analog (R1 H), or derivatives, composed of a large alkyl group (R1 cyclohexyl) resulted in a significant loss of potency (hCB2 EC50 20 mM). The anti-inflammatory effect of 12 (R1 cyclohexyl) was evaluated in a mouse zymosan-induced paw inflammation (ZIPI) model 33 .

The Role of Bacteria in Inflammatory Bowel Disease

Instead of invoking a single bacterial species as a cause for Crohn's disease, an important alternative hypothesis has been that Crohn's disease is induced by a shift in the commensal intestinal bacterial population, known as dysbiosis. Dysbiosis could potentially be harmful in at least two ways. First, bacteria (or parasites and fungi) that are potentially pathogenic might normally exist at low levels but become predominant and pathogenic during dysbiosis. These species may directly damage the intestinal wall or may be recognized as harmful, and as a result incur an inflammatory response. The best noninflammatory bowel disease clinical example of this paradigm is pseu-domembranous colitis where C. difficile colonization is elevated following treatment with antibiotics. This inappropriate elevation of C. difficile can lead to destruction of the surface epithelium, which then leads to inflammation. Importantly, and in contrast to Crohn's disease (see below), pseudomembranous colitis is...

Miscellaneous structures

SSAO VAP-1 is an emerging target for drug discovery. There is considerable scientific evidence pointing to this protein as a potential target for many inflammatory diseases. The target is amenable to drug discovery, and a considerable effort to discover novel, useful drug candidates is underway. However, there is reason to question the validity of this target. Drugs such as hydralazine and phenelzine which inhibit SSAO VAP-1 at therapeutic doses have not been reported to have anti-inflammatory properties. True validation will only come when some of the newer, very potent and selective agents are evaluated in patients suffering from these inflammatory conditions.

Intracranial Pressure And Malignant Cerebral Edema

Cerebral edema can be attenuated by a number of medical interventions, including administration of mannitol, glycerol, and hypertonic saline. These drugs increase the osmolality of the blood and facilitate the exchange of free water from the interstitial to the intravascular space they produce their effect primarily in regions of the brain where the BBB is intact. When the BBB is impaired, the drugs can leak into ischemic brain tissue and theoretically lead to intracranial compartmental shift and increased risk of herniation, although these fears do not seem to be borne out clinically (126). Despite the fact that mannitol, glycerol, and hypertonic saline all decrease ICP, no data suggest that their use improves outcome in large hemispheric stroke (127-131). The benefit of corticosteroids in acute stroke is unproven, and corticosteroids do not attenuate edema associated with cerebral infarction their use should, therefore, be avoided (132). Hypothermia might attenuate cerebral edema...

PDE7 and immunological response

The PDE7 enzyme has been shown to be predominant over PDE3 and PDE4 in CD4 + and CD8+ T cells 25 , Moreover, the PDE7A1 isoform, expressed in T cells, has been proposed to be essential for T lymphocyte activation and proliferation, since blocking its expression by a PDE7A antisense oligonucleotide correlated with an increase in cAMP and decrease in proliferation and IL-2 production 7 , As an elevation of cAMP has been associated with immunosuppressive and anti-inflammatory effects 6,26 , PDE7 inhibition could be useful in the treatment of T cell-mediated diseases, Specifically, the similar pattern of PDE7A1 expression in T cells in mice and human 11,15 reinforces the potentially prominent role of PDE7A1 in regulating T cell related diseases compared to PDE7A2, which is not expressed in the immune system 15 ,

Further Clinical Opportunities For Hdac Inhibitors

In addition to polyglutamine-induced neurodegeneration, HDAC inhibitors may find application in immunological disorders. Cytokine production is regulated through selective patterns of histone acetylation 69 . The HDAC inhibitor SAHA exhibits anti-inflammatory properties both in vitro and in vivo 70,71 . In a model of lipopolysaccharide induced inflammatory response in mice, SAHA decreases the levels of circulating pro-inflammatory cytokines, such as TNF-a, IL-1-b, IL-6 and IFN-g. Recently, TSA and SAHA have also been shown to antagonize systemic lupus erythematosus in a mouse model 72,73 .

Induction of Tolerance by DCs in the Steady State

Subtype of DCs expresses the Fas ligand, enabling these DCs to kill Fas-bearing activated T cells. However, those effects did not depend on the activations status of the DCs. Rather, a certain subtype of DCs seemed to be involved in this tolerogenic action. Interestingly, those DC subsets also express the DEC-205 receptor, and it is conceivable that DEC-205+ DCs are prone to induce tolerance rather than immunity. Lu et al. (31) show that DEC-205+ liver DCs are poor T-cell stimulators and induce T cells that produce the anti-inflammatory cytokine IL-10. In addition, a subset of DEC-205+ CD8+ DCs has been identified in mouse spleen, that is able to curb proliferation of CD8+ T cells in vitro by inducing TH2-like cytokines (32). So, even if the functional aspects of DEC-205-mediated antigen presentation to the tolerance induction remains elusive, DEC-205 expression might serve as a suitable marker to characterize tolerogenic DCs (33,34). In addition to killing T cells after antigen...

Problems not confined to obstetrics

Most severe reactions on the labour ward are caused by drugs, especially antibiotics, intravenous anaesthetic drugs (particularly suxamethonium) and oxytocin. Some well-recognised cross-reactions exist, e.g. up to 10 of individuals with true penicillin allergy are also allergic to cephalosporins. Allergy to amide local anaesthetic drugs is rare but has been reported, as has allergy to preservatives used in local anaesthetic and other drug preparations. Non-steroidal anti-inflammatory drugs and paracetamol often cause rashes but these are usually mild following brief oral rectal courses, although severe reactions have been reported following intravenous administration. Reactions may also follow administration of gelatine intravenous fluids and blood. Latex allergy has become an increasing problem amongst both medical staff and patients, driven by an increase in the wearing of gloves because of concern about transmission of blood-borne infection and the ubiquitous use of latex in home...

Disorders of the Soft Tissues

A bursa is a fluid-filled sac between a bone and a tendon or muscle that allows the tendon to slide smoothly over the bone. Bursitis occurs when repeated stress and overuse cause the bursa to become inflamed and swollen with excess fluid. Bursitis also can result from injury, rheumatoid arthritis, gout, or infection. Bursitis most often occurs in the shoulder but also can affect the hip, knee, elbow, Achilles tendon, or ankle. Often the nearby tendon also becomes swollen. Bursitis usually can be treated with rest, ice, and nonsteroidal anti-inflammatory medication. Occasionally it is necessary for a doctor to withdraw excess fluid from the bursa using a needle and syringe. If an infection is present, the doctor will prescribe antibiotics. If there is no infection, the doctor may inject a Treatment of tendinitis may include making changes in your activities or routine, receiving corticosteroid injections, taking nonsteroidal anti-inflammatory medications such as aspirin or ibuprofen,...

Disorders of the Joints

Osteoarthritis is diagnosed based on your symptoms and the results of a physical examination. X rays usually are taken to confirm the diagnosis. There is no cure for osteoarthritis. Your doctor probably will prescribe a nonsteroidal anti-inflammatory drug to relieve symptoms. Severe episodes of inflammation may be treated by injecting a corticosteroid drug directly into the affected joint. Massage, heat treatments, and warm baths may help relieve symptoms. Regular, gentle exercise (such as walking or swimming) will help your joints stay flexible. Maintaining a healthy weight (see page 67) will reduce the strain on your joints. For some people doctors may recommend joint replacement (see page 310).

Selective Glucocorticoid Receptor Modulators

Since GR-regulated gene transcription is believed to follow two distinct functional pathways, ligands could be further differentiated by selectively following one mode of action. When a steroid or other ligand associates with GR in the cytosol, the resulting GRC is transported into the nucleus where it regulates gene expression via direct action as an endogenous transcription factor or by indirectly affecting the function of existing transcription factors associated with proinflammatory gene expression. The antiinflammatory effects of the GRC are believed to occur by the indirect path, wherein the GRC adopts a conformation possessing an affinity for existing transcription factors such as AP-1 (13) or NFkB (14-17), thereby repressing the transcription of proinflammatory cytokines and other inflammatory mediators (14,18-20). The direct function of GRCs as conventional transcription factors regulates endogenous endocrine function. The dimeric form of the GRC forms a transcription factor...

Disorders of the Wrist and the Hand

Your doctor probably will recommend that you rest the affected hand and avoid the repetitive activity that is causing the problem. You also may need to wear a splint or a brace to immobilize your wrist while allowing you to continue using your hand. Nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen can relieve pain and inflammation. Injections with corticosteroids may be prescribed if pain persists. Surgery to relieve the pressure on the median nerve (a procedure called carpal tunnel release) is performed in severe cases that do not respond to other forms of treatment. To reduce pain and swelling, place an ice pack on the finger immediately after the injury occurs. See your doctor as soon as possible. He or she may X ray the finger to make sure it is not broken. The doctor probably will immobilize your finger with a splint for 2 to 3 months to help the joint heal properly. In some cases the doctor may insert a wire through the joint to hold the finger straight while...

Agents Exhibiting Il1 Modulation

Patients was observed by the second week of treatment. After 4 weeks of treatment at 40 to 120 mg daily dose, 5 was judged superior to placebo in all measures tested. This dual inhibitor of 5-lipoxygenase and cyclooxygenase (5-LO CO) also inhibits the synthesis of both 17 kD IL-1 and 34 kD pro-IL-1 in LPS or zymosan stimulated murine peritoneal macrophages in vitro (64) and is reported to reduce IL-1 activity in the synovial fluid of rheumatoid arthritic patients by 35 in paired measurements of IL-1 from synovial fluid (65). Many analogs of 5 have been patented as antiinflammatory agents and analgesics (66).

Arachidonic Acid Metabolism

The increase in Ca2+ during ischemia stimulates Ca2+-dependent phospholipase activity, which mobilizes arachidonic acid and other lipids from the phospholipid pool (4). Arachidonic acid is used as a substrate by cyclooxygenase (COX), lipoxygenase, and selective cytochrome P450 enzymes possessing ra-hydroxylase or epoxygenase activity. Early work with pharmacologic inhibitors implicated a greater role for COX than for lipoxygenase in hippocampal neuronal death from global ischemia (78). The anti-inflammatory epoxyeicosatrienoic acids produced by expoxygenases (79,80) and the proinflammatory 20-hydroxyeicosatetraenoic acid produced by ra-hydroxylase (81,82 - have not been well studied in global cerebral ischemia. COX-1 is constitutively expressed in neurons, glia, and endothelium, whereas COX-2 is constitutively

Discuss the properties of nitric oxide NO

Deactivation on entering the circulation also limits the effectiveness of NO to the period in which it is administered by inhalation. Because storage in oxygen produces toxic higher oxides of nitrogen, especially nitrogen dioxide (NO2), NO is stored in nitrogen and blended with ventilator gases immediately before administration. The potential for increased methemoglobin levels during NO administration should also be recognized. It has proinflammatory and antiinflammatory effects, and the significance of this is not fully understood. It also impairs platelet aggregation and adhesion.

Disorders of the Knee

Ligament injuries are first treated with RICE (see page 65). You also must use some form of support (such as crutches or a cane) to avoid putting weight on the injured knee joint. In some cases a splint or a brace is needed for long-term immobilization of the joint. Nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen will help relieve pain and reduce inflammation. Arthroscopy (see box) often is needed to repair the ligament. Your knee joint may be unstable after this injury and may be more susceptible to recurring ligament or cartilage tears. Your doctor may recommend working with a physical therapist or an athletic trainer on exercises that will stabilize the ligaments and tendons and strengthen the leg muscles.

Factors That Influence Incidence

Table 3 lists important factors that may influence the likelihood of an adverse reaction during the use of a drug or therapeutic agent. Some drugs are more likely to be involved in reactions than others. Antibiotics, especially p -lactams and sulfonamides, followed by aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) and central nervous system (CNS) depressants, are most commonly involved in these serious reactions. The p-lactam antibiotics, trimethoprim sulfamethoxazole (TMP-SMX), and whole blood are most likely to be involved in skin rashes, the most common manifestation of adverse reactions. Minor drug reactions (e.g., nausea) are more often involve with narcotic use, antibiotics, and cardiovascular drugs.

Treatment with Soluble TNFR1 to Eliminate Ad Inflammation in Lung and Liver

Certain cytokines such as TNFa can result in rapid clearance of adenovirus or viral therapy. Administration of anti-inflammatory cytokines, such as IL-10, can reduce inflammation and prolong gene therapy 44 , We have evaluated the effect of the treatment with a novel TNF-binding protein (TNF-bp), a polyethylene-glycol (PEG)-linked dimer of sTNFRl, on inflammation of the lung and viral clearance after intranasal administration of AdCMVLacZ (1 x 1010 pfu) 45, 46 (Fig. 3, see color insert). Three days after intranasal administration, there was a moderate inflammatory infiltrate in the lungs of control (CT)-treated C57BL 6-+ 4- mice, which peaked at day 7 and was nearly resolved by day 30 (Fig. 3A). In contrast, 3 days after administration of AdCMVLacZ, there was no evidence of an inflammatory infiltrate in the lungs of TNF-bp-treated C57BL 6-+ + mice and only minimal evidence of infiltration was observed from day 3 through day 30. We next determined the expression of LacZ adenovirus...

Other modifications of established antibiotics classes

BAL19403 14 is a new macrolide that is highly potent against erythromycin-resistant and clindamycin-resistant propionibacteria 66,67 . Potent antiinflammatory activity and good pre-clinical safety make BAL19403 a good candidate for topical treatment of acne 68-70 . AR-709 15 is a new di-aminopyridine in Phase I clinical trials derived from a program aimed at optimizing dihydrofolate reductase (DHFR) inhibitors treating respiratory infections caused by multi-drug-resistant Streptococci, Pneumococci, and Staphylococci 71-73 . In enzyme assays using wild-type and mutant DHFR isolated from S. pneumoniae and S. aureus, the IC50 for AR-709 was 12 x-60 x lower than for trimethoprim (TMP) for the wild-type and 50-100 x lower for the mutant enzyme 74 . Accordingly, AR-709 has demonstrably more potent antibacterial activities than TMP against both TMP-S and TMP-R strains of S. pneumoniae and S. aureus. AR-709 is currently in a radiolabelled Human Microdose study where preliminary results...

Rafts As Potential Targets Of Therapies

Glucocorticoids (GCs) are a class of cholesterol-derived steroids produced by the hypothalamic-pituitary-adrenal axis that have significant immunosuppressive and anti-inflammatory effects on the immune system (69). GCs inhibit T cell responses and consequently, GCs have been widely prescribed in the treatment of autoimmunity, allergy and inflammatory disease and in the prevention of graft rejection. The primary targets for the action of GCs appear to be intracellular receptors that alter nuclear gene transcription. However, recent evidence indicates that GCs alter both the lipid composition of the inner leaflet of the lipid rafts and the palmitoylation of cellular proteins (70). Thus, in GC-treated T cells the raft associated proteins LAT, Cbp and Lck fail to be compartmentalized. Knowledge of the mechanism by which GCs alter membrane composition may provide new targets for immunosuppression that can be further exploited.

Searching for Alzheimers Disease Therapies In Your Medicine Cabinet The Epidemiological and Mechanistic Case For NSAIDs

Despite this bleak clinical picture, an intriguing story has emerged in recent years from epidemiological studies asking whether the use of any currently marketed drugs is associated with a decreased risk of AD. Two classes of drugs have consistently emerged in the affirmative for this question. The first are the nonsteroidal anti-inflammatory drugs (NSAIDs), commonly used either acutely in the treatment of mild to moderate pain, swelling, and fever, or more chronically in the treatment of rheumatoid arthritis. The second is a class of popular cholesterol-lowering drugs known collectively as statins, used as a primary preventative to block the development of atherosclerosis. This epidemiological record has spawned a growing literature that seeks to explore the mechanisms by which both of these classes of drugs might have their purported protective effects in AD. associated with damaged neurons and potentially exacerbates the pathological processes underlying AD. This presence of a...

Management options General management

Use of simple analgesics such as paracetamol and codeine-based preparations is acceptable during pregnancy but non-steroidal anti-inflammatory drugs should be avoided whenever possible. If their use is considered essential, treatment should be agreed with the obstetrician and fetal cardiac ultrasound monitoring arranged because of the risk of premature closure of the ductus arteriosus. Amitriptyline may be prescribed as a co-analgesic, especially if pain is disrupting normal sleep patterns. In cases of severe back pain, strong opioid analgesia may be required.

Potency of natural antioxidants

Flavonoids are diphenylpropanes that commonly occur in plants and are frequently components of human diet. They are consumed in relatively high quantities in our daily food. The main source of flavonoids is vegetables, fruits and beverages. For example, the content of quercetin glycoside in outer leaves of lettuce could be as high as 237 mg kg fresh weight, and the content of kaemferol glycoside in kale could be 250 mg kg fresh weight.2,3 It has been found that flavonoids and other polyphenols possess antitumoral, anti-allergic, anti-platelet, anti-ischemic, and anti-inflammatory activities. Epidemiological evidence for the importance of flavonoids in reducing mortality from coronary heart disease was provided by the Zutphen Elderly Study.4 The role of dietary phenolic antioxidants in vivo, protecting against cancer, has also been underlined by some epidemiolog-ical studies.5,6 In these studies, flavonoids and other dietary compounds have been mentioned as statistically beneficial and...

Anti Allergic Effects of H1 Antagonists

Second-generation antihistamines have been shown to have diverse anti-allergic or anti-inflammatory pharmacological activities. The clinical significance of these activities has not been well documented, but based upon their nature, it can be presumed that part of the therapeutic effect of these agents may indeed be related to these properties. The antiallergic activities of second-generation antihistamines include the following (J) prevention of histamine release from mast cells and basophils (2) downregulation of intracellular adhesion molecules such as ICAM-J on epithelial membranes (3) decreased eosinophil influx into tissues (4) prevention of the generation of superoxide (5) prevention of the generation of leukotrienes and (6) prevention of the production of interleukins. For example, fexofenadine has been shown to decrease the expression of ICAM-J on epithelial cells and prevent the release of interleukin A and granulocyte-macrophage colony-stimulating factor (GM-CSF). Also,...

Immunomodulatory phosphorylcholinecontaining proteins secreted by filarial nematodes

The filariids are arthropod-transmitted nematode worms which parasitise a wide range of vertebrates including man (1). As indicated above, infection in humans is long- term and the net effect of this is that hundreds of millions of people are currently infected with these parasites (2). The longevity of these worms is readily explained by the immunomodulation theory as defects in immune responsiveness have been revealed in infected individuals (3,4). Some discrepancy exists as to the exact nature of these defects but generally, they incorporate impairment of lymphocyte proliferation and bias in production of both cytokines, e.g., reduced production of interferon gamma (IFN-y) increased synthesis of IL-10 (an antiinflammatory cytokine) and immunoglobulin subclasses - greatly elevated lgG4 (an antibody of little value in eliminating pathogens due to an inability to activate complement or bind with high affinity to immune cells such as monocytes) decreases in other IgG subclasses....

Hypoxiainducible Factor 1 And Cytochrome P450

Hypoxia-inducible factor 1 (HIF-1) is a key transcription factor in the brain's response to hypoxic stress (91) . Induction of HIF-1a and its downstream targets, such as erythropoietin, have been implicated in hypoxic preconditioning in vivo in newborn and adult models (92-94). HIF-1a-mediated induction of cytochrome P450 2C11 expression is an important mechanism of tolerance by hypoxic preconditioning in astrocytes (95). Cytochrome P450 2C11 is an arachi-donic acid epoxygenase that is also increased in rats by focal ischemic preconditioning (96). It metabolizes arachidonic acid to epoxyeicosatrienoic acids (EETs), which have been implicated in control of the cerebral circulation (97) . EETs have also been shown to protect the heart against ischemia reperfusion injury (98) and to protect astrocytes from OGD-induced cell death (95). In addition, EETs are antiinflammatory (99), antioxidant (100), and antipyretic (101). Finally, EETs have been shown to stimulate ATP-sensitive potassium...

Fourth Generation Agents Highly p Extremely Long Acting

At present, formoterol and salmeterol are recommended for use under very specific guidelines. These include no more frequent use than two puffs two times a day, and warnings that they should be initiated cautiously in patients with worsening or deteriorating asthma, should not be used for acute symptoms, and should not be considered a substitute for oral or inhaled corticosteroids. Thus, experts recommend use of salmeterol concomitantly with inhaled anti-inflammatory therapy and availability of a shorter-acting inhaled bronchodilator for acute symptoms.

Lower Respiratory Tract Infections Exacerbation of COPD and Bronchitis

In a series of studies conducted from 1988 to 2001, the clinical and bacter-iologic efficacy for antibiotics given for 3 to 5 days compared to 8 to 14 days was essentially equivalent (Table 2) (28). Quinolones and macrolides are frequently prescribed because of their spectrum of activity against pneumococci, H. influenzae, and atypical pathogens. These agents also have favorable pharmacokinetics and achieve high concentrations in lung tissue. The anti-inflammatory effect of macro-lides may also be beneficial, and azithromycin, in particular, has a long half-life that is ideal for SCAT. Thus, shorter courses of quinolones (5 days) and perhaps azithromycin for 3 days appear to have equivalent efficacy and benefits when compared to 10- to 14-day courses for treatment of AE-COPD with other comparators (28,44-46).

Are there any medications that I should adjust or stop taking while Im being treated for osteoporosis

Presumably, you are taking prescription medications that are important to the treatment of your medical conditions. However, it's very important for you to be taking the smallest dosage that gives you the maximum benefit of any medication. Sometimes a medicine is prescribed by one clinician who is unaware of medication that you are taking that was prescribed by a different clinician. So, you need to be certain that all of your clinicians know about all of the medications you are taking. In addition, there are some over-the-counter medications such as non-steroidal anti-inflammatory drugs (NSAIDS), like ibuprofen, aspirin, and naproxen, and antacids that can increase side effects or interfere with your new medications for osteoporosis.

Therapy And Prophylaxis

Due to difficulty in propagating the virus in vitro, there is no vaccine. During local epidemics, transfusion of packed erythrocytes or the administration of normal human immunoglobulin may afford some protection to individuals at risk of aplastic crisis. There is no indication for termination of pregnancy if maternal infection occurs, since no abnormalities have been noted in babies born to mothers whose pregnancy has been complicated by B19 infection. The symptoms of B19 infection may be treated as appropriate erythrocyte transfusion for aplastic crisis, calomine lotion for pruritic rash, anti-inflammatory agents for arthritis. Intravenous immunoglobulin is effective in controlling chronic infection in the immunocompromised.

Toxicities Linked To Descriptors For The Overall Properties Of The Molecule

Sections 2.1-2.3 summarize the weight of evidence that links specific structural fragments (toxicophores) to adverse outcomes. Literature evidence linking overall molecular properties and adverse outcomes is less prevalent. One approach is to examine the link between overall physicochemical parameters and toxic endpoints and has been the subject of an excellent recent review which discusses the physico-chemical parameters commonly associated with toxicity endpoints 62 . Lipophili-city , usually described by the octanol-water partition coefficient, (log P) or the calculated value, (clog P) appears to be the most general requirement in quantitative structure-toxicity relationships (QSTRs) reflective of the link between lipophilicity and access to tissue and cell compartments through membrane permeability and lipophilicity driven non-specific binding to hydrophobic protein sites or membranes. This paper also highlights the literature evidence linking lipophili-city to metabolism,...

Clinically Investigated Isozymeselective Pi3k Inhibitors

Selectivity of these compounds (and also the PIK-39, PIK-293, PIK-294 analogs) is postulated to arise due to a conformational rearrangement of Met752 (Met804 in PI3Kg), which is distal to the highly homologous adenine binding pocket 22 . CAL-101 is being evaluated as an oral therapeutic in two phase I clinical trials in a recently completed trial as a treatment for allergic rhinitis (presumably as an anti-inflammatory agent) 92 and in an on-going trial as a treatment for cancer, focused on patients with hematologic malignancies 88,93-95 . CAL-101 inhibits p110d-mediated basophil activation in whole blood with an IC50 of 30-70 nM and has demonstrated well-tolerated, sustained plasma concentrations of 500-5000 nM in a 7-day multidose healthy human volunteer study, indicating a viable therapeutic index 88,94 . Although data on preclinical PI3Kd-selective inhibitors other than IC-87114 is limited, recent patent disclosures suggest that this area remains active 96-98 .

Clinical Efficacy Asthma

The key features of cromolyn and nedocromil are outlined in Table 3. Their action is clearly anti-inflammatory. Biopsy and bronchoalveolar lavage studies obtained after provocative challenges or during long-term therapy both demonstrate significant reductions in inflammatory markers. Both drugs decrease the number of indolent and activated eosinophils found in bronchoalveolar lavage fluid and biopsy specimens of respiratory mucosa. In addition, cromolyn decreases the amount of albumin present in bronchoalveolar lavage fluid. Key Features of Cromolyn and Nedocromil Use in Asthma Anti-inflammatory

Specific Aspects of Post Operative Pain

The action of endogenous opioids on peripheral sites following tissue damage. Opioid receptors are transported toward the central terminal in the dorsal horn and toward the periphery. These peripheral receptors then become active following local tissue damage. This occurs with unmasking of opioid receptors and the arrival of immunocompetent cells that possess opioid receptors and have the ability to synthesize opioid peptides. This has led to an interest in the peripheral administration of opioids following surgery or topical administration of morphine. NSAIDs are commonly used for peripheral analgesia and one of their actions is a reduction in the inflammatory response. Agents such as aspirin and other NSAIDs provide their anti-inflammatory action by blocking the cyclooxigenase pathway. Cyclooxigenase exists in two forms, COX1 and COX2. While COX1 is always present in tissues, including the gastric mucosa, COX2 is induced by inflammation. This presents an opportunity for the...

Acute renal failure related to pregnancy

Septic abortion and massive haemorrhage (traditionally caused by placental abruption, although any cause of hypovolaemia may be followed by renal failure). Other important causes include pyelonephritis, drug reactions (especially non-steroid anti-inflammatory drugs NSAIDs ), acute fatty liver and incompatible blood transfusion. In most cases, ARF is caused by acute tubular necrosis, although cortical necrosis has been seen after abruption and pre-eclampsia. Problems are those of ARF generally, especially related to fluid balance and the apparently increased susceptibility of pregnant women to developing pulmonary oedema.

IgE Receptor Crosslinking And Activation Of Apcs

Recent data have also suggested a role of FceRI on the differentiation of APCs mediated by factors involved in anti-inflammatory pathways and known to promote a tolerogenic state. The production of the tolerogenic cytokine IL-10 has been induced by the engagement of FceRI on human monocytes from atopic donors at the beginning of the IL-4 GM-CSF driven culture process, and this prevented the differentiation of the DCs (34). This resulted in the production of macrophage-like cells that were poor stimulators of T cells. This area needs further study to characterize the precise role of FceRI in the modulation of DCs and the clinical consequences attached to this finding.

Mechanisms Of Action

Asthma is an inflammatory airways disease. As such, it should come as no surprise that medications with broad anti-inflammatory effects such as GCs are among the most effective classes of medications for asthma. Multiple studies have shown GCs to act at several levels of the inflammatory response (Table 1), with their primary effect coming mainly from their ability to inhibit the expression and or production of molecules involved in the initiation and maintenance of the inflammatory response. Specifically, they inhibit the upregulation of adhesion molecules on endothelial cells that are required for the adhesion and subsequent migration of inflammatory cells to sites of inflammation. They also inhibit the production of cytokines involved in inflammatory cell recruitment, activation, and proliferation. GCs also display potent vasoconstrictive properties. By decreasing capillary permeability at sites of inflammation, less plasma exudation occurs, resulting in a reduction in the...

Impact Of Cap Guidelines On Outcomes

Several observational studies have found that antimicrobial regimens as listed in the guidelines are associated with decreased mortality and shorter length of stay (LOS) for patients who require hospitalization. Stahl et al. evaluated 100 prospective patients hospitalized with CAP. Patients were stratified according to the antibiotic received. Patients who received macrolides (usually IV erythromycin or PO clarithromycin) within the first 24 hr of admission had a markedly shorter LOS (2.8 days) than those not so treated (65). The investigators speculate that the direct antimicrobial effect against atypical pathogens as well as a beneficial immunolo-gic or anti-inflammatory effect may be responsible for the advantage of the macro-lides. In a study of 12,945 Medicare patients (65 years of age), Gleason and colleagues found the addition of a macrolide to a second- or third-generation cephalosporin resulted in a significantly reduced 30-day mortality for elderly patients hospitalized with...

Adverse Effects of Systemic Glucocorticoid Therapy

As all nucleated cells in the body have a common GC receptor, all are potentially affected by GC therapy and thus susceptible to the development of untoward effects. These effects can occur immediately (i.e., metabolic effects) or can develop insidiously over several months to years (i.e., osteoporosis and cataracts). In addition, some adverse effects are limited to children (growth suppression) while others appear to require interaction with other drugs (nonsteroidal anti-inflammatory agents and peptic ulcer disease). Most adverse effects occur in a dose-dependent and duration-of-treatment manner, although this has not been uniformly noted. Table 3 lists many of the common adverse effects associated with chronic GC use.

Prodrugs With Other Benefits

Mechanism-based GI side effects of non-steroidal antiinflammatory drugs have been previously addressed by a prodrug approach 43 . A similar strategy was applied to the antiviral castanospermine (64). This compound causes osmotic diarrhea due to inhibition of intestinal sucrases. The ester-type prodrug celgosivir (65) was relatively inactive at this enzyme and the GI side effects were minimized, allowing advanced clinical trials as an anti-HCV agent. Celgosivir was readily absorbed ( 94 of the dose) orally, and converted rapidly to the parent ( 92 of the dose) upon absorption 44 .

An Entirely New Method of Managing Allergic Diseases

By effectively neutralizing free allergic antibody, anti-IgE is both therapeutic for existing disease and preventive for anticipated allergic states. It does not relieve symptoms immediately like those chemical agents, such as antihistamines, leukotriene receptor antagonists, and bronchodilators, nor is it an anti-inflammatory agent like corticosteroids. However, it chokes off the pathway leading to the sensitization of mast cells, basophils, and activated eosinophils and their discharge of inflammatory mediators. It has also has other regulatory effects, which desensitize the allergic responsiveness.

Mechanistic Basis of the Efficacy of Statins in Atherothrombosis

Reactive oxygen species (ROS) affect vascular function. Statins attenuate the Ang II-induced ROS production in vascular smooth cells 19 . Statins decrease the number of inflammatory cells in atherosclerotic plaques and thereby exert anti-inflammatory effects on the vascular wall.

Roles in Biological Processes

As stated earlier, the primary function of Bik is to inhibit serine proteases 28 . These proteases are increased during inflammation and play key biochemical roles in the inflammatory process. Inhibition by Bik imparts anti-inflammatory activity. In all of these processes, the serine proteases initially exist as zymogens in their pro or enzymatically inactive forms (e.g., trypsin-ogen, plasminogen, proelastase, prothrombin, chymotrypsinogen). Enzymatic cleavage of blocking groups establishes their enzymatic activity. During chronic inflammatory disease, inflammatory cells (neutrophils, mast cells, macrophages, and lymphocytes) become increasingly more damaging to tissues. Anti-inflammatory action of Bik reduces cell death mediated by immune cell. Proinflammatory cytokine tumor necrosis factor-a (TNF-a) and interleukin-1 fl (IL-1) cause expression of multiple inflammatory and innate immunity genes for additional cytokines, chemokines, adhesion molecules, and enzymes. Aprotinin has been...

Relevant Vascular Effects of Statins

A wide array of inflammatory cells such as monocytes, macrophages, and T lymphocytes are observed in atheroma, which suggests complex inflammatory process in atherosclerosis. These inflammatory cells secrete cytokines, thereby modifying endothelial function, SMC proliferation, collagen degradation, and thrombosis. Statins possess anti-inflammatory properties because of their ability to reduce the number of inflammatory cells in atherosclerotic plaques. Inhibition of adhesion molecules, such as intercellular adhesion mol-ecule-1 (ICAM-1), by statins is one mechanism which leads to a reduced recruitment of inflammatory cells under statin treatment. Expression of LOX-1, which is observed to be upregulated early during atherogenesis, is also a potent pro-inflammatory signal, since it is associated with the upregulation of a variety of other pro-inflammatory signals. LOX-1 expression and its activation are both suppressed by statins 23 . High levels of C-reactive protein (CRP), released...

Chronic Systemic Inflammation

Adiponectin is one of the most abundant gene products in adipose tissue. In contrast with many of the other adipokines, the levels of which rise in obesity, plasma adiponectin levels are decreased in obesity, and levels increase following weight loss. The predominant metabolic effects of adiponectin are in the liver and in skeletal muscle and include increased glucose uptake, inhibition of gluconeogenesis, and increased fatty acid oxidation (37). Adiponectin also has anti-inflammatory properties. Pertaining to asthma, adiponectin inhibits proliferation and migration of cultured vascular smooth muscle cells induced by mitogens (38). It will be important to determine whether adiponectin has similar effects on airway smooth muscles (ASM), especially because both the AdipoR1 and AdipoR2 receptors are expressed in cultured human ASM cells. In this context, it should be noted that increased ASM mass is a feature of human asthma, and modeling studies have shown that increased muscle mass...

How is pain of malignant origin treated

Pain of malignant origin should be aggressively treated with a multiple therapeutic approach. This approach should initially be pharmacologic with introduction of short- and long-acting opioid preparations and some adjuvants. Adjuvants should be chosen according to the symptomatology and their side-effect profile. For example, nonsteroidal antiinflammatory drugs (NSAIDs) and steroids are very useful in the treatment of bone pain from primary or metastatic disease anticonvulsants and tricyclic antidepressants (TCAs) can be used in the treatment of neuropathic pain from compression or from previous interventions such as chemotherapy or radiation therapy.

Nonhydroxamic Acid Nonpeptidic MMP Inhibitors

Bayer found that the known anti-inflammatory agent, fenbufen, possesses modest inhibitory activity against gelatinase-A, and has prepared more potent analogs, such as 18 (46). This compound features a carboxylic acid zinc binding group and a cyclic imide P1 substituent. A large P1' b iphenyl group ensures selectivity for the deep-pocket MMPs. A variety of nonpeptidic natural-product MMP inhibitors have been discovered by screening. These include pycnidione (19 Merck 89), futoenone derivatives (e.g., 20 OAS-1148 OsteoArthritis Sciences) (90), betulinic acid (21 Sterling Winthrop 91), gelastatins (e.g., 22 92), and tetracyclines such as aranciamycin and minocycline, for which chemical modification (e.g., 23 CMT-1) has enabled the separation of MMP activity from antibiotic activity (93,94). Two of these compounds feature a carboxylic acid that may serve as a ZBG for others, it is possible that a ring hydroxyl and or carbonyl chelates the active site zinc(II) ion. In the case of the...

Potential Therapeutic Indications

Of apoE knockout mice with the selective 11p-HSD1 inhibitor (10mg kg d for 8 weeks in diet) significantly attenuated the deposition of aortic plaque and cholesterol ester. This was accompanied by a decrease in circulating monocyte chemoattractant protein-1, suggesting that 11p-HSD1 inhibition has a direct anti-inflammatory effect at the blood-vessel wall.

Clinical Use Of Theophylline In Asthma

Tration and may become symptomatic toward the end of the 24-h dosing interval. With pellet formulations, the beads should be added to moist food (e.g., applesauce) to ensure their dissolution. Sustained-release tablets should not be crushed because this destroys their slow-release properties. An algorithm for initial dosing and final dosage adjustment based on serum concentration measurement may be found in a recent review of safety and efficacy of theophylline in children with asthma (Hendeles et al.). Because adverse effects of theophylline become manifest as the serum concentration of 20 g mL is approached, it is best to aim for the 8-15 g mL range in the majority of patients. Also in in vitro animal models and human studies, theophylline has anti-inflammatory immunomodulatory effects at serum concentrations in the 5-10 g mL range. (See dosing recommendations in Table 3.) A recent head-to-head study of oral theophylline vs inhaled beclomethasone showed similar rates of asthma...

Pharmacological Management

Inhaled corticosteroids (ICSs) are the most effective anti-inflammatory medications for the treatment of chronic, persistent asthma and are the cornerstone of asthma treatment. Numerous studies have shown that regular use of ICSs reduces airway hyperreactivity, the need for reliever medications, the risk of hospitaliza-tion, and risk of death from asthma. They have also been shown to improve pulmonary function, exercise tolerance, and quality of life. They are available as pressurized me-tered-dose inhalers (pMDIs), dry-powdered inhalers (DPIs), and nebulizer solutions. ICSs available in the United States include beclomethasone, budesonide, fluticasone, mometasone, and triamcinolone. Clinical trials are proceeding with the next generation of ICS, including ciclesonide. Long-Acting p2-Agonists. Two inhaled long-acting p2-agonists (LABAs) (formeterol and salmeterol) and one oral LABA (oral albuterol) are approved for use in asthma. They exert their effects by...

Ciclesonide Asthma Copd [69

Ciclesonide, a new inhaled corticosteroid (ICS), is indicated for the prophylactic treatment of persistent asthma. ICS treatment is a widely accepted standard of care for maintenance therapy of chronic asthma, and the currently available agents include fluticasone propionate, budesonide, triamcinolone acetonide, flunisolide, and beclomethasone dipropionate. These agents exert their potent anti-inflammatory effects via modulation of the glucocorticoid receptor (GR). Although ICS drugs are generally safe and well tolerated compared with oral corticosteroids, many have measurable systemic exposures, and concerns over potential side effects resulting from it severely limit the dose at which they can be administered for long-term therapy. Systemic adverse effects associated with corticosteroids include HPA axis suppression, osteoporosis, abnormal glucose metabolism, cataracts, and glaucoma, some of which could potentially occur with the long-term use of high dose ICS. The key...

A1 Adenosine Receptor Antagonists L971 Bg9928 Fk838 And Wrc0571

Activation of A1 adenosine receptors (ARs) may play a role in mucus production by human epithelial cells 16 , human bronchial smooth muscle contraction 17 , and neutrophil chemotaxis 18,19 . However, activation of ARs on macrophages has the following effects inhibits the production of several pro-inflammatory cytokines, including tumor necrosis factor-a (TNF-a), IL-6, and IL-8, and enhances the release of the anti-inflammatory cytokine, IL-10 20-22 . Several compounds from different classes of A1 AR antagonists are noteworthy for either demonstrating efficacy in animal models of asthma or entering clinical trials for asthma or other indications. Xanthines are considered classical antagonists for ARs. For example, the non-selective xanthine AR antagonists, theophylline (1,3-dimethylxanthine) and caffeine (1,3,7-trimethyl-xanthine), display micromolar affinity at various AR subtypes, with some affinity at the AR 23 . Over the past 20 years, multiple research groups contributed to the...

Other Therapeutic Uses for Cromolyn or Nedocromil

And adolescents with moderate to severe atopic dermatitis. All subjects concomitantly applied a mid-potency topical steroid. Objective severity decreased significantly in the cromolyn-steroid group compared to the group treated with steroid alone. The study authors posit an additive anti-inflammatory effect based on the different mechanisms of action employed by corticosteroids and cromolyn.

Inflammation and Immune Response in Human Longevity

However, apart from disease states, there is a natural evolution of cytokine production with aging, including decreased T cell proinflammatory IL-2 and interferon-7 (type II pro-inflammatory IFN-7), decreased non-T cell antiinflammatory type I IFN (IFN-a and IFN- ), and increased non-T cell proinflammatory IL-1, IL-6, and tumor necrosis factor a (TNF-a) 90 . The IL-6 is one of the pathogenic elements of inflammatory and age-related diseases (AD and atherosclerosis) and has been defined as the cytokine for gerontologists'' 91 . human longevity, as some studies revealed a different expression of cytokines in elderly compared to young people 108, 109 . In particular, a study performed on Italian centenarians reported that the-1082G IL-10 single-nucleo-tide polymorphism, associated to elevated production of the cytokine, was increased in male centenarians 110, 111 . Differently, the +847T single-nu-cleotide polymorphism at the IFN-7 gene, part of the 12CA +847T haplotype responsible for...

Future Therapeutic Options for Allergic Rhinitis

Future therapies for allergic rhinitis may include immunomodulators such as monoclonal anti-IgE (omalizumab), inhibitors of inflammatory cell immigration into the nasal mucosa, and anti-inflammatory therapies. Omalizumab binds to soluble IgE and also results in a reduction in the high-affinity receptor for IgE on mast cells and basophils and possibly on select dendritic cells. If dosed according to the recommendation of 0.16 mg kg U IgE, the free plasma IgE concentration is reduced to approx 15 U mL. This results in reduced allergic rhinitis symptoms and improvement in asthma. The necessity for injecting this compound and the cost are the major limitations on the eventual application of omalizumab for allergic rhinitis. A variety of anti-inflammatory therapies or immunomodulators have been considered or tried for rhinitis. Syk-kinase inhibitor is an example of such therapeutic approaches. Syk-kinase is a signaling protein important for mast cell and basophil degranulation. By applying...

A2b Adenosine Receptor Antagonists Cvt6883 MRE 2029F20 LAS38096 And Osip339391

There is substantial evidence to indicate that A2B ARs contribute to airway inflammation in asthma and that a compound specifically inhibiting the A2B AR may have beneficial effects 46-49 . Activation of A2B ARs on human bronchial smooth muscle cells (BSMCs) has been shown to induce the release of the inflammatory cytokines IL-6 and monocytic chemotactic protein-1 50 . A2B AR activation on human bronchial epithelial cells (HBECs) releases IL-19, which in turn activates human monocytes to induce the release of TNF-a, thereby upregulating A2B AR expression on human bronchial endothelial cells 51 . The above evidence supports the hypothesis that adenosine plays a role in asthma, and its effects may be at least, in part, mediated through the A2B AR. Several high-affinity and selective antagonists of A2B AR have been reported recently by several groups. These examples can be used to fully understand the therapeutic potential of A2B AR antagonists as anti-inflammatory and anti-angiogenic...

Pathophysiology of

Anti-inflammatory activity of Bik is highly correlated to glomerulonephritis 4, 95,96 . Bik provides protection to renal cells from ischemia reperfusion injury by reducing immune-mediated apoptotic signals that typically lead to cell death 4, 30, 81 . Bik also has a protective affect on proximal tubule epithelial cells under stress 97 . Bik levels increase with a-1-microglobulin during renal tubule damage 4 . uTis are a distinct group of Bik protease inhibitors that are central to the body's innate anti-inflammatory response. Bik provides a measure of acute and chronic inflammatory conditions and allows insight to the cellular response to inflammation. It is therefore plausible that screening for Bik especially in the urine may provide a diagnostic tool for assessing inflammation.

Treatment of Olfactory Disorders

Steroids Among many other effects corticosteroids act as anti-inflammatory drugs, the anti-inflammatory effects being produced via a number of different pathways including inhibition of phospholipase A2 through induction of lipocortin 225 . They reduce submucosal edema and mucosal hypersecretion and thereby increase nasal patency. Systemically administered steroids are of help in many sinu-nasal disease (SND) patients 129, 226-228 . For example, Stevens reported that systemic administration of steroids was effective in 12 of 24 patients with SND-related olfactory loss 229 . In addition to the anti-inflammatory activity it has been postulated that corticosteroids directly improve olfactory function 230, 231 by modulating the function of ORN through effects on olfactory Na, K-ATPase 225 . In fact, also based on our own experience, systemic ste

Leptin in rheumatoid arthritis

AIA is a model of immune-mediated joint inflammation induced by administration of methylated bovine serum albumin (mBSA) into the knees of immunized mice (21). The severity of arthritis in leptin- and leptin receptor-deficient mice was reduced in this model (22). The milder form of AIA seen in ob ob and db db mice, as compared with their controls, was accompanied by decreased synovial levels of interleukin (IL)-1P and TNF-a, decreased proliferative response to antigen of lymph node cells in vitro, and a switch toward production of Th2 cytokines (22). Serum levels of all isotypes of anti-mBSA antibodies were significantly decreased in arthritic ob ob mice as compared with controls. Thus, in AIA leptin probably contributes to joint inflammation by regulating both humoral and cell-mediated immune responses. However, joint inflammation in AIA depends on the adaptive immune response, which is known to be impaired in ob ob and db db mice, so recent studies investigated the effect of leptin...

Safer Antiinflammatories The COX2Specific Inhibitors

A recent report compared the incidence of endoscopic ulcers in rheumatoid arthritis patients taking celecoxib, traditional NSAIDs, and placebo (43). The inclusion of a placebo group is critical in these types of studies, since ulcers may occur in patients without use of antiinflammatory drugs, a consideration frequently overlooked. In this trial, the incidence of upper GI tract ulcers was 4 99 (4 ) in the placebo group, 9 148 (6 ) on celecoxib 100 mg bid, 6 145 (4 ) on 200 mg bid, 8 130 (8 ) on400 mg bid, and 36 137 (26 ) on naproxen 500 mg bid. The ulcer rates on celecoxib were not significantly different from those on placebo but were significantly less than naproxen. Anti-inflammatory drug required Anti-inflammatory drug not required the aspirin therapy may mandate cotherapy to prevent bleeding. For those requiring antiinflammatory therapy, the use of a COXIB instead of a traditional NSAID to avoid the moderate additive risk seen in the CLASS study may be...

Didronel etidronate is usually prescribed for Pagets disease Is it ever prescribed for osteoporosis

The treatment of choice for Paget's is a bisphospho-nate. Bisphosphonates Actonel, Fosamax, and Didronel are FDA-approved for the treatment of Paget's. Unlike the longer dosing regimens of other bisphosphonates, Didronel is generally prescribed for only two weeks to three months at a time depending on the dosage, with a rest period off the medication lasting at least three months. This regimen is usually repeated for about two years. Didronel is taken on an empty stomach without eating or drinking for two hours after taking it. Didronel should still be prescribed with caution in those with upper intestinal disorders. The most common side effects include nausea, diarrhea, and flatulence. Medications that cause stomach upset, such as non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, naproxen, or aspirin, can increase the risk for ulcer or heartburn. Table 11 has information on Didronel.

PI3K8selective inhibitors

Comparing crystal structures of d-selective versus pan-PI3K inhibitors has revealed a selectivity pocket that is occupied by the o-toluyl ring of 26 and related analogs 102 . Selective PI3K8 inhibitors can adopt a twisted propeller conformation that pan-isoform inhibitors cannot achieve. The fluorophenol group of 27 probes a separate affinity pocket and improves potency against d while maintaining 50-fold selectivity against a, p, and g. Compound 28, with changes to the quiazolinone ring and the hinge binding motif, inhibits d with an IC50 34 nM and displays 100-fold isoform selectivity 101 . PI3 kinase inhibitors with distinct isoform selectivity profiles (8, 8 g, and pan-PI3K) have been used to define the in vitro anti-inflammatory signature associated with each profile 103 .

A2a Adenosine Receptor Agonists Cgs21680 UK371104 AND GW328276

Activation of A2A AR has the following anti-inflammatory effects on various cell types inhibition of the release of histamine and tryptase from mast cells 33 and reduction of chemotaxis, in addition to activation degranulation of neutrophils 19,34,35 . Activation of A2A AR also increases the production of anti-inflammatory IL-10 from monocytes and macrophages 36 . Therefore, various A2A AR agonists have been evaluated in animal models of asthma and have even advanced into clinical trials 37 . Early on, compound 5 was synthesized by exploring the SAR studies on N-ethyl carboxamide adenosine (NECA), a non-selective AR agonist 38 . Substitution at the 2-position of NECA with a phenethyl amine derivative provided compound 5 (CGS-21680) that displayed 144-fold selectivity for the A2A AR over the A1 AR 38 . When compound 5 was given intratracheally, it inhibited both the early and the late inflammatory reactions in allergen-challenged Brown Norway rats 39 . Compound 5 inhibited both...

Aimin Xu Yu Wang and Karen S L

Adiponectin is a glycosylated adipokine selectively secreted from adipocytes. The native adiponectin forms several oligomeric complexes, including trimer, hexamer, and high-molecular-weight (HMW) 12-18 multimers. In the past 5 yr, numerous clinical studies have demonstrated a close association between low plasma levels of adiponectin (hypoadiponectinemia) with obesity-related diseases, including dyslipidemia, atherosclerotic cardiovascular diseases, type II diabetes, hypertension, fatty liver, and certain types of cancers. Mounting experimental evidence shows that adiponectin is an endogenous insulin sensitizer with potent antidiabetic, anti-atherogenic, and antiinflammatory properties. It also has profound protective actions against hepatic and cardiac injury. Different oligomeric forms of adiponectin might act on different tissue targets and stimulate distinct cellular pathways. Two putative adiponectin receptors (adipoRl and adipoR2) have recently been cloned. In vitro studies...

Interference with lymphocyte activation

Inhibiting T Cell cycle progression Blockade of the b-3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (HMGCR) by inhibitors (HMGCRI), also known as statins, results in interference with T cell cycle progression and plays a beneficial role in chronic neuroinflammation (Aktas et al., 2003 Waiczies et al., 2005). The HMGCR pathway utilizes several key enzymes to convert intermediary metabolites via a series of sequential organic reactions (rearrangements, condensation reactions, etc.) that finally lead to cholesterol synthesis. This pathway is a source of hydrophobic molecules important for a wide range of inter- and intracellular functions involving hormonal communication, protein synthesis, electron transport, protein lipid modification for membrane anchoring and intracellular signaling (via isoprenoids), and cell membrane maintenance (via cholesterol). Previous studies demonstrating the anti-inflammatory nature of statins revealed the possible benefits of employing...

Circulating Biomarkers for Vulnerable Plaques

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a 50-kDa calcium-insensitive lipase produced predominantly by macrophages and lymphocytes. This enzyme resides mainly in LDL particles in plasma. The plasma levels and activity of Lp-PLA2 are significantly elevated in patients with CAD and ischemic stroke risk 72, 105 . The enzyme activity of Lp-PLA2 is implicated in the formation of inflamed, rupture-prone plaque 106 . Although Lp-PLA2 has been reported to exhibit both pro- and anti-inflammatory activities, its primary role appears to be proatherogenic. In this context, Lp-PLA2 hydrolyzes oxidized phospholipids such as those within oxidized LDL, generating proinflammatory moieties lysophosphatidylcholine and oxidized fatty acids 104 . Lp-PLA2 was shown to be expressed within the necrotic core and in macrophages, notably apoptotic macrophages, surrounding vulnerable and ruptured plaques in patients who suffered from sudden coronary death 73 . Inhibition of Lp-PLA2 was demonstrated...

Antibiotics targeted against the ribosome

The region of domain V of the 23S rRNA includes the peptidyltransferase center from the peptidyltransferase site to the beginning of the exit tunnel for the nascent polypeptide chain (Ban et al., 2000 Nissen et al., 2000) and encompasses the binding site for both the 14-membered macrolide erythromycin and the 16-membered ring macrolide tylosin (Douthwaite et al., 2000 Poulsen et al., 2000). It also overlaps partially with other antibiotics such as the streptogramins and lincosamides, e.g., clindamycin. Structure-based design of novel antibiotics that fill one or more of these RNA subsites should be a productive enterprise. The peptide exit channel is about 100 A long (see Nissen et al., 2000), lined mostly with RNA from domains I to V of the 23S rRNA but also with some contacts from proteins L4, L22, and L39. Whether inhibitors can be found that fill the tunnel is unclear, but it is worth noting that the nonsteroidal antiinflammatory drug flurbiprofen blocks a tunnel into the active...
