8-Bromo-1-iso-butyl-3-methyl-7-(thietanyl-3)xanthine (II) was synthesized by alkylation of 8-bromo-3-methyl-7-(thietanyl-3)xanthine (I) with isobutyl bromide. Nucleophilic substitution of II with thioglycolic acid gave 2{[1-iso-butyl-3-methyl-7-(thietanyl-3)xanthin-8-yl]thio}acetic acid (III). A series of water-soluble salts of 2{[1-iso-butyl-3-methyl-7-(thietanyl-3)xanthin-8-yl]thio}acetic acid (IVa-h) were synthesized by reaction of III with organic and inorganic bases. Compounds possessing antiaggregant activity on the level of acetylsalicylic acid were found among salts IV. All obtained compounds except for IVa and IVc suppressed lipid peroxidation less than ascorbic acid. However, all synthesized compounds suppressed generation of reactive oxygen species by phagocytes, in contrast to ascorbic acid.
