説明Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor (IC50s = 0.9-2.7 and 1.5-20 μM, for human COX-1 and COX-2, respectively). It is also an active metabolite of diclofenac methyl ester and diclofenac amide . Diclofenac inhibits release of arachidonic acid (Item Nos. 90010 | 90010.1 | 10006607) induced by A23187 in isolated rat peritoneal neutrophils and macrophages (IC50s = 60 and 10 μM, respectively). Transdermal administration of diclofenac inhibits carrageenan-induced paw edema in rats. Formulations containing diclofenac have been used in the treatment of pain associated with osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis.

来歴Diclofenac sodium is a classic nonsteroidal anti-inflammatory drug (NSAID), known for its potent antipyretic, analgesic, and anti-inflammatory effects, and is marketed under brand names such as Voltaren. Its discovery and widespread use have had a profound impact on the treatment of pain and inflammation.Discovery and Patent (1965): Diclofenac sodium was synthesized by a team of researchers Rudolf Pfister and Alfred Sallmann at the Swiss pharmaceutical company Ciba-Geigy AG (now part of Novartis) while searching for a highly active and well-tolerated NSAID. The compound was patented in 1965.First Market Launch (1973): After extensive preclinical and clinical trials, diclofenac sodium was first marketed globally in 1973 under the brand name Voltaren. Its design philosophy is based on clear principles and aims to be an effective cyclooxygenase (COX) inhibitor.

Diclofenac sodium is a nonsteroidal anti-inflammatory compound and cyclooxygenase (COX) inhibitor. Oxidation of diclofenac sodium produces the metabolite 4'-hydroxy diclofenac) which demonstrates specific inhibition of Cox-2. Inhibition of Cox by diclofenac and 4'-hydroxy diclofenac suppresses prostaglandin E2 synthesis, producing anti-inflammatory and analgesic effects. Diclofenac is also shown to stabilize the native tetrameric conformation of transthyretin (TTR) fibrils, preventing the formation of insoluble amyloidogenic TTR deposits. Diclofenac Sodium is a substrate of CYP2C9. It is also used as an inhibitor of Cox-1 and Cox-2.
