A series of novel 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. These compounds showed potent antifungal activities in vitro and in vivo. In particular,(2R, 3R)-3-[4-(4-cyanophenyl) thiazol-2-yl]-2-(2, 4-difluorophenyl)-1- (1H-1, 2, 4-triazol-1-yl)-2-butanol (12g; ER-30346) showed potent and well-balanced in ...
