Physiologically and pharmacologically active het(aryl)chalcogenylacetates of tris(2-hydroxyethyl)ammonium of pharmacopeial purity have been synthesized by the reaction of het(aryl)chalcogenylacetic acids with sodium (potassium) hydroxide and triethanolamine hydrochloride by one-pot method in quantitative yield (up to 99.8%).

Difficultly accessible 1-R-indol-3-ylsulfanyl(sulfonyl)acetic acids 1-R-IndYCH(2)CO(2)H (R = H, Me, Bn; Y = S, SO2) 1a-Id were prepared. Their reaction with tris(2-hydroxyethyl)amine yielded tris(2-hydroxyethyl) ammonium 1-R-indol-3-ylsulfanyl(sulfonyl)aceetates (protatranes) 2a-2d. The immunoactive properties of 2a-2d were studied. Protatranes 2a, 2c, and 2d proved to be effective immunosuppressive agents (up to 99.5% inhibition of mice splenocyte proliferation in vitro).
