The effect of water-soluble synthetic antioxidant TS-13 (sodium 3-(3'-tert-butyl-4'-hydroxyphenyl) propyl thiosulfonate) on life span of different lines of Drosophila melanogaster under normal conditions and survival under oxidative stress induced by hydrogen peroxide and paraquat has been investigated. Introduction to the diet of 1% TS-13 prolonged the life span of males and females of D. melanogaster long-living line Canton S, had no effect on short-living Oregon R life span and reduced the life span of male D. melanogaster line IgI(558)OR/Cy, heterozygous on tumor suppressor recessive lethal mutation. When flies were exposed to hydrogen perexide, TS-13 significantly enhanced Canton Smale and Oregon R female survival. Under the influence of paraquat antioxidant protected Canton S female and Oregon R flies of both sexes. Despite the fact that the anti-aging and protective properties of synthetic phenol antioxidant TS-13 depend essentially on the genotype and gender, in the extreme conditions of oxidative stress its positive effect pronounced.
