Abstract
Abstract 3-Aralkyloxy-2,3-dihydro-2-(imidazolylmethyl(benzo(b)thiophenes and related derivatives having antifungal, antibacterial, and antiprotozoal activity are prepared by the reaction of the corresponding 2,3-dihydro-3-hydroxy-2-(imidazolylmethyl)benzo(b)thiophene or related derivative and an aralkyl halide. Preferred compounds are those where the aralkyl function is a hetercyclic aromatic, particularly 2-chloro-3-thenyl, and where the benzene nucleus is substituted by chlorine or fluorine. Pharmaceutical formulations comprising compounds of this invention are described, as well as the method for their use in treating microbial infections.
