Discovery of novel indazole-linked triazoles as antifungal agents

The in vitro and in vivo activities of a series of (2R, 3R)-2-(2,4-difluorophenyl)-3-(substituted indazol-1-yl)-1-(1H-1,2,4-triazol-1-yl)butan-2-ol as potential antifungal agents are described. In particular, the analog 12j having 5-bromo substitution on the indazole ring exhibited significant antifungal activity against a variety of fungal cultures (Candida spp. and Aspergillus spp.). In addition, oral administration of 12j showed its excellent efficacy against Candida albicans in a murine infection model and the significantly improved survival rates of the infected mice.
