Resveratrol, a natural polyphenol that possesses anti-oxidant, anti-inflammatory, cardioprotective, blood-sugar-lowering, antiaging, and anti-cancer properties. It has a wide spectrum of targets including cyclooxygenases(i.e. COX, IC50=1.1 μM), lipooxygenases（LOX, IC50=2.7 μM, kinases, sirtuins, c-IAP1, c-IAP2, livin and XIAP. Resveratrol regulates gene transcription via activation of the stimulus-regulated protein kinases Raf and ERK and the stimulus-responsive transcription factors TCF and Egr-1. 4'-O-methyl-trans-resveratrol is an ether. It is functionally related to a trans-resveratrol.
