定義

ChEBI:Resveratrol is a stilbenol that is stilbene in which the phenyl groups are substituted at positions 3, 5, and 4' by hydroxy groups. It has a role as a phytoalexin, an antioxidant, a glioma-associated oncogene inhibitor and a geroprotector. It is a stilbenol, a polyphenol and a member of resorcinols.

説明

Resveratrol, a non-flavonoid polyphenolic compound, is widely found in the skin of red grapes, nuts, berries, Polygonum cuspidatum root, etc. It is reportedly known to exhibit pharmacological properties including anti-cancer, anti-inflammatory, antioxidant, neuroprotectant, anti-atherogenic property and reduces the synthesis of pro-atherosclerotic substances.

生物活性

A phytoestrogen with antitumor, antioxidant, antiplatelet, anti-inflammatory and antifungal effects. Inhibits cytochrome P450 1A1 (IC 50 = 23 μ M) and displays mixed agonist/antagonist actions at ER α and ER β estrogen receptors. Converted into the anticancer agent piceatannol (4-[(1E)-2-(3,5-Dihydroxyphenyl)ethenyl]-1,2-benzenediol ) by cytochrome P450 1B1

作用機序

Resveratrol can be found in the skins and seeds of grapes and in peanuts. It has demonstrated potent antioxidant, anti-inflammatory, and anti-proliferative activities. Topical application of resveratrol in mice demonstrated photoprotection by significantly decreasing UVB-mediated generation of hydrogen peroxide and infiltration of leukocytes. Its antiproliferative properties are related to the inhibition of cellular events associated with tumor initiation, promotion, and progression, and the triggering of apoptosis in tumor cells.
