Antifungal spectrum, in vivo efficacy, and structure-activity relationship of ilicicolin H
Ilicicolin H is a polyketide-nonribosomal peptide synthase (NRPS)-natural product isolated from Gliocadium roseum, which exhibits potent and broad spectrum antifungal activity, with sub- μg/mL MICs against Candida spp., Aspergillus fumigatus, and Cryptococcus spp. It showed a novel mode of action, potent inhibition (IC50 = 2-3 ng/mL) of the mitochondrial cytochrome bc1 reductase, and over 1000-fold selectivity relative to rat liver cytochrome bc1 reductase.
