Synthesis of glutathione C60 derivative and its protective effect on hydrogen peroxide-induced apoptosis in rat pheochromocytoma cells

Oxidized glutathione C60 derivative has been synthesized and characterized in our research. As a novel derivative of C60, the glutathione C60 derivative is soluble in dimethylsulfoxide, dimethylformamide and dimethylacetamide. Rat pheochromocytoma (PC12) cells are treated with hydrogen peroxide and underwent cytotoxicity; apoptotic death is determined by MTT assay, flow cytometry analysis, PI/Hoechst 33342 staining and glutathione assay. The results suggest that glutathione C60 derivative has the potential to prevent oxidative stress-induced cell death without evident toxicity.
