A reappraisal of the potential chemopreventive and chemotherapeutic properties of resveratrol.

Resveratrol, a phytoalexin found in grapes and wines, has been reported to exhibit a wide range of pharmacological properties and is believed to play a role in the prevention of human cardiovascular disease (the so-called 'French paradox'). This molecule may also play a major role in both cancer prevention and therapy. In this review article we summarize the recent advances that have provided new insights into the molecular mechanisms underlying the promising properties of resveratrol. These include cyclooxygenase, nitric oxide synthase and cytochrome P450 inhibition, as well as cell cycle effects, apoptosis modulation and hormonal activity.
