Background: Studies have emphasized the effect of Trigonella foenum-graecum extract on the reduction of pain and inflammation. Objective: In this research we investigated the mechanisms of Trigonella foenum-graecum extract in reducing pain and inflammation induced by formalin. Methods: Male Albino mice (weight 20 - 25 g) were evaluated through the injection of 2 microliters of formalin to th...
Aspirin exerts its analgesic, antipyretic and anti-inflammatory actions by inhibiting the enzyme cyclooxygenase and thus preventing the formation and release of prostaglandins. The elucidation by John Vane of the mechanism of action of aspirin in 1971 was followed twenty years later by the discovery of a second cyclooxygenase enzyme, COX-2 and the rapid development of selective inhibitors of th...
The activity of two cyclooxygenase-2 enzyme inhibitors, Celecoxib and Lumiracoxib, could be suppressed by coupling to photo-labile protecting groups, so-called photocages. These groups could be further functionalized with a peptide targeting vector for specific cellular delivery. The enzyme inhibition potential of the cyclooxygenase-2 inhibitors could be regained upon two-photon excitation with...
Since their approval in 1998, the popularity of selective cyclooxygenase-2 (COX2) inhibitors has swung from a domination of drug sales to serious disputes about their cardiovascular safety. Despite the numerous studies on COX2 inhibitors that have emerged, drawing conclusions about their cardiovascular safety has been complicated by conflicting results, underpowered clinical trials, and the lac...
Introduction: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are used in treating pathologic conditions such as fever, pain and inflammation by inhibiting cyclooxygenase and consequently prostaglandin production. Recently , the discovery of different isoforms of this enzyme, Cyclooxygenase-1 (COX-1) and Cyclooxygense-2 (COX-2), has led to the synthesis and introduction of novel drugs with selec...
Prostaglandins are important mediators of renal physiology and disease. The main enzyme which governs the synthesis of prostaglandins is cyclooxygenase (COX), also called prostaglandin endoperoxide synthase (PGS). Until recently it was assumed that only one cyclooxygenase gene and protein exists, an enzyme which is now called cyclooxygenase-l (COX-I) or the 'constitutive' isoform. Between 1989a...
