title: Resveratrol may reduce oxidative stress induced by platinum compounds in human plasma, blood platelets and lymphocytes.
abstract: Resveratrol (trans-3,4',5-trihydroxystilbene), a polyphenolic compound found in grapes and wine, has been shown to have anti-inflammatory, anti-oxidant, anti-tumor and anti-platelet activities. Using different methods, we show that resveratrol reduces oxidative stress induced by cisplatin (cis-diamminedichloroplatinum II) and selenium-cisplatin conjugate ([NH(3)](2)Pt(SeO(3)), Se-Pt) in human blood platelets, lymphocytes and plasma. Resveratrol decreased the production of 8-epi-prostaglandin F(2) (a biomarker of lipid peroxidation) in control blood platelets and platelets treated with platinum compounds (10 microg/ml), and markedly reduced activities of different anti-oxidative enzymes (glutathione peroxidase, superoxide dismutase and catalase) in these cells. A combined action of resveratrol and Se-Pt evoked a significant decrease of DNA damage (measured by comet assay) in lymphocytes compared with cells treated with Se-Pt only. Resveratrol also caused a distinct reduction of total anti-oxidant level in plasma after incubation with platinum compounds. Therefore, anti-oxidative activity of resveratrol may diminish oxidative stress and damage to cellular biomolecules (lipids, proteins and DNA) induced by platinum compounds.
