COX inhibitors

COX (Cyclooxygenase), which is also called prostaglandin-endoperoxide synthase, plays the rate-limiting role in the process of converting arachidonic acid to prostaglandins and thromboxane. Cyclooxygenase is the molecular target for aspirin and NSAIDs(non-steroidal antiinflammatory drugs). COX contains 3 isoenzymes which are called COX-1, COX2, and COX3.

S1396 Resveratrol (trans-Resveratrol) Resveratrol has a wide spectrum of targets including cyclooxygenases(i.e. COX, IC50=1.1 μM), lipooxygenases(LOX, IC50=2.7 μM), kinases, sirtuins and other proteins. It has anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects. Resveratrol induces mitophagy/autophagy and autophagy-dependent apoptosis.
