title: Haplofungins, new inositol phosphorylceramide synthase inhibitors, from Lauriomyces bellulus SANK 26899 II. Structure elucidation.
abstract: Eight new inositol phosphorylceramide synthase inhibitors: haplofungin A, B, C, D, E, F, G and H, were discovered in a culture broth of the fungus Lauriomyces bellulus SANK 26899. The planar structures for these haplofungins were elucidated by various spectroscopic analyses and a GC/MS analysis of their degradation products. All eight compounds were found to comprise an arabinonic acid moiety linked through an ester bond to a modified long alkyl chain.
