Metabolite Identification
Common NamePF1163A
DescriptionPF1163A is a fungal metabolite belonging to the chemical class of polyketide-nonribosomal peptide hybrids. It is recognized for its role as an antifungal agent, specifically inhibiting sterol-C4-methyl oxidase, a critical enzyme in the biosynthesis of ergosterol, which is vital for fungal cell membrane integrity. The biosynthesis of PF1163A involves a unique polyketide synthase-nonribosomal peptide synthetase hybrid, PfaA, characterized by an unusual domain organization featuring tandem condensation domains and a terminal condensation domain (PMID:39719272 ). Isolated from the marine-derived fungus Penicillium meleagrinum var., PF1163A has been shown to inhibit ergosterol synthesis in Saccharomyces cerevisiae, leading to the accumulation of 4,4-dimethylzymosterol while decreasing ergosterol levels (PMID:12546418 ). This inhibition is significant as it disrupts essential fungal processes, confirming PF1163A's potential as a novel antifungal agent (PMID:12546418 ). Additionally, resistance studies indicate that strains overexpressing the ERG25 gene exhibit resistance to PF1163A, further underscoring its specific mechanism of action (PMID:12546418 ). Overall, PF1163A represents a promising candidate for antifungal development, highlighting the importance of natural products in therapeutic applications.
