The antioxidant activities of 5-hydroxyoxindole (1) and newly synthesized 3,5-dihydroxy-3-phenacyl-2-oxindole derivatives against rat liver microsome/tert-butylhydroperoxide system-induced lipid peroxidation and hydrogen peroxide-induced intracellular oxidative stress were investigated. Compound 1 and its derivatives showed significant suppression of lipid peroxidation and an intracellular oxidative stress. The effects of the more lipophilic derivatives tended to be greater than that of the original compound 1. The cytotoxicity of all of the oxindole derivatives on human promyelocytic leukemia HL60 cells was lower than that of 2,6-di(tert-butyl)-4-hydroxytoluene (BHT), a widely used phenolic antioxidant. These results show that compound 1 and its 3-substituted derivatives could be good lead candidates for future novel antioxidant therapeutics.
