Novel antifungal agents: Triazolopyridines as inhibitors of β-1,6-glucan synthesis

Preparations and in vitro antifungal activities of triazolopyridines, imidazopyridines, and a pyrazolopyridine were reported. Among those scaffolds, triazolopyridine was found to be the specific inhibitor of the synthesis of β-1,6-glucan, an essential component of the fungal cell wall, and to show potent antifungal activities against several Candida species.
