Resveratrol interferes with all three stages of carcinogenesis initiation, promotion and progression. Experiments in cell cultures of varied types and isolated subcellular systems in vitro imply many mechanisms in the pharmacological activity of resveratrol. In some lineages of cancer cell culture, resveratrol has been shown to induce apoptosis, which means it kills cells and may kill cancer cells.Resveratrol has been shown to induce Fas/Fas ligand mediated. Resveratrol also possesses antioxidant and anti-angiogenic properties. 


Main Functions:

Resveratrol is naturally occurring phytoalexin produced by some higher plants in response to injury or fungal in fection. Phytoalexins are chemical substances produced by plants as a defense against in faction by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
