PF-1163B

PF-1163B is a depsipeptide antifungal isolated from Penicillium that inhibits ergosterol (ERG) synthesis (IC50 = 34 ng/ml). It inhibits growth of C. albicans (MIC = 32 µg/ml) but not of other Candida strains, A. fumigatus, or HepG2 cells. It acts synergistically with fluconazole (Cay-11594) to reduce growth of azole-resistant C. albicans (MIC = 2 and 0.0016 µg/ml alone and in combination, respectively). PF-1163B is a hydroxy form of PF-1163A (Cay-22065).Formal Name: 3S-[[4-(2-hydroxyethoxy)phenyl]methyl]-4,10R-dimethyl-13R-pentyl-1-oxa-4-azacyclotridecane-2,5-dione. CAS Number: 258871-60-2.
