Applications
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.
