Mechanism of action of NSAIDs-Any injury to cell cause rupture of cell membrane causing a release of … NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. Neutral derivatives of indomethacin also failed to bind to mCRTH2, suggesting that the negatively charged carboxylate moiety participates in a key ligand-receptor interaction. The propionic acid derivatives such as ibuprofen and naproxen are generally better tolerated than other NSAIDs. Lima. Nonsteroidal anti-inflammatory drugs (NSAIDs) are members of a drug class that reduces pain, decreases fever, prevents blood clots, and in higher doses, decreases inflammation.Side effects depend on the specific drug but largely include an increased risk of gastrointestinal ulcers and bleeds, heart attack, and kidney disease.. Recent studies from our laboratory have shown that derivatization of the carboxylate moiety in substrate analogue inhibitors, such as 5,8,11,14- eicosatetraynoic acid, and in nonsteroidal antiinflammatory drugs (NSAIDs), such as indomethacin and meclofenamic acid, results in the generation of potent and selective cyclooxygenase-2 (COX-2) inhibitors (Kalgutkar et al. 1999).

C. Isosteric replacement of indole ring of indomethacin with an indene ring can produce sulindac. Indomethacin is practically insoluble in water and sparingly soluble in alcohol. As a first generation NSAID inhibitor, oxaprozin binds to and inactivates both isoforms of cyclooxygenase (COX-1 and-2), thereby blocking the conversion of arachidonic acid to pro-inflammatory prostaglandins. Reported differences in toxicity between NSAIDs must be interpreted in light of different utilization patterns and interpatient variability.6 Gastrointestinal side effects are most common.
