Synthesis and Pharmacological Activity of Trifluoromethyl-Containing Imidazo[1,2-A]Benzimidazoles

Abstract

A series of 2-(4-trifluoromethylphenyl)- and 2-trifluoromethyl-9-dialkylaminoalkylimidazo[1,2-a]benzimidazoles were synthesized for the first time by reacting 2-amino-1-dialkylaminoalkylbenzimidazoles and 2-bromo-1-[(4-trifluoromethyl)phenyl]ethanone or 1-bromo-3,3,3-trifluoroacetone and were tested for analgesic and antiplatelet activity, glycogen phosphorylase and dipeptidyl peptidase-4 inhibitory activity, and in vitro glycation of bovine serum albumin.
