Lanosterol 14α-Demethylase (CYP51)/Heat Shock Protein 90 (Hsp90) Dual Inhibitors for the Treatment of Invasive Candidiasis

Abstract

Invasive candidiasis has attracted global attention with a high incidence and mortality. Current antifungal drugs are limited by unfavorable therapeutic efficacy, significant hepatorenal toxicity, and the development of drug resistance. Herein, we designed the first generation of lanosterol 14α-demethylase (CYP51)/heat shock protein 90 (Hsp90) dual inhibitors on the basis of antifungal synergism. Among them, dual inhibitor MM4 exhibited potent in vitro and in vivo antifungal activity against Candida albicans and effectively inhibited important fungal virulence factors (e.g., hyphae, biofilm). Therefore, CYP51/Hsp90 dual inhibitors show great promise in the development of novel antifungal drugs to combat invasive candidiasis.
