A compound represented by the general formula:
wherein R1 and R2 denote a halogen atom or hydrogen atoms; R3 means a hydrogen atoms or lower alkyl group; r and m stand for 0 or 1; A is N or CH; W denotes an aromatic ring or a condensed ring thereof; X means another aromatic rings, an alkanediyl group, an alkenediyl group, or an alkynediyl group; Y stand for -S-, etc.; Z denotes a hydrogen atom, etc., or a salt thereof, and intermediates thereof or a salt thereof as well as processes for the preparation thereof, and pharmacetical composition suitable for use as an antifungal agent.
A new series of thiazole-containing triazole antifungals was synthesized and evaluated for antifungal activity against a variety of clinically isolated pathogenic fungi in vitro and against systemic candidosis in vivo. Among these compounds, (±)-1-(2, 4-difluorophenyl)-1-[4-(2, 4-difluorophenyl)thiazol-2-yl]-2-(1H-1, 2, 4-triazol-1-yl)ethanol (ER-24161) showed the most potent and well-balanced in vitro activities and excellent in vivo efficacy. We also achieved an enantioselective synthesis of the more potent enantiomer of ER-24161.
