title: Structural and functional characteristics for the antiinflammatory effect of new water-soluble sulfur-containing phenol antioxidants.
abstract: Structurally related phenols containing the p-alkylthiosulfonate substituent and partially hindered by tert-butyl groups were synthesized for the search and development of new synthetic antioxidant, which would be effective in vivo in preventing free radical-induced pathological processes. Sodium 3-(3'-tert-butyl-4'-hydroxyphenyl)propylthiosulfonate had high antiinflammatory activity and produced a dose-dependent effect (IC(50)=36 mg/kg). Changes in the length of the carbohydrate chain in the p-alkyl substituent had no effect on in vitro antiradical activity of the test compounds. However, the decrease in the length of this chain by one methylene unit was accompanied by reduction of antiinflammatory activity of the end product. Lengthening of the chain did not modulate these properties.
