PF-1163B

PF-1163B is an antifungal agent produced by Penicillium sp. II. PF-1163B inhibits ergosterol (ERG) synthesis (IC50 = 34 ng/ml). PF-1163B showed potent growth inhibitory activity against pathogenic fungal strain Candida albicans but did not show cytotoxic activity against mammalian cells.

ChEBI: PF 1163B is a macrolide antibiotic that is 4,10-dimethyl-1-oxa-4-azacyclotridecane-2,5-dione substituted by a 4-(2-hydroxyethoxy)benzyl group at position 3 and a pentyl group at position 13 (the 3S,10R,13S stereoisomer). It is isolated from Penicillium sp.PF1163 and exhibits antifungal activity against the pathogenic fungal strain Candida albicans TIMM1768. It has a role as an antifungal agent and a Penicillium metabolite. It is a macrolide antibiotic, a lactam and an aromatic ether.
