Abstract

A series of 2-(trifluoromethyl)-1H-benzimidazole derivatives with various 5-and 6-position bioisosteric substituents (–Cl,–F,–CF3,–CN), namely 1–7, were prepared using a short synthetic route. Each analogue was tested in vitro against the protozoa Giardia intestinalis and Trichomonas vaginalis in comparison with albendazole and metronidazole. Several analogues had IC50 values< 1 μM against both species, which make them significantly ...
