Haplofungins, novel inositol phosphorylceramide synthase inhibitors, from Lauriomyces bellulus SANK 26899 III. Absolute structure of haplofungin A

Abstract

The absolute structure of haplofungin A, a potent fungal inositol phosphoceramide (IPC) synthase inhibitor from Lauriomyces bellulus SANK 26899, was determined by chiral GC/MS analysis, NMR and X-ray crystallographic analysis of the derivatives of degradation products.
