Synthesis and Antidiabetic Activity of Thiazolo[2,3-f]Purine Derivatives and Their Analogs

Abstract

Thiazolo[2, 3-f]purine derivatives and their analogs – dihydrothiazolo[2, 3-f]purine, 7-(thietan-3-yl)purine, and 8-(2-hydroxypropylthio)purine derivatives – were synthesized. The compounds synthesized here had no effects on protein glycation reactions using glucose; they gave weak inhibition of glycogen phosphorylase; they had no hemorheological activity. Substances with hypotensive activity greater than that of Dibazol were found. A number of substances had hypoglycemic effects greater than those of chlorpropamide and Adebit. Two compounds inhibited dipeptidylpeptidase-4, but were less active than reference agent vildagliptin.
