Mycoversilin, a new antifungal antibiotic. II. Structure elucidation.

Mulundocandin, a new lipopeptide antibiotic. II. Structure elucidation.

The structure of a new antifungal antibiotic, mulundocandin, C48H77N7O16, was elucidated by high field NMR experiments e.g., homo- and heteronuclear correlation spectra, distortionless enhancement by polarization transfer (DEPT) spectra as well as nuclear Overhauser effect. The compound is a lipopeptide antibiotic belonging to the echinocandin class.

Aranorosin, a novel antibiotic from Pseudoarachniotus roseus. II. Structure elucidation.

Aranorosin, a new antifungal antibiotic, has been isolated from the culture filtrate and mycelium of a strain of Pseudoarachniotus roseus Kuehn. The antibiotic, C23H33NO6, contains a novel 1-oxaspiro[4,5]decane ring system. The structure (I) has been elucidated on the basis of spectroscopic and chemical analysis.

Formamicin, a novel antifungal antibiotic produced by a strain of Saccharothrix sp. II. Structure elucidation of formamicin.

A novel antifungal antibiotic, formamicin, was isolated from the culture broth of Saccharothrix sp. MK27-91F2. The absolute structure of formamicin was determinated by spectroscopic and X-ray crystallographic analysis and degradation study.

Glomosporin, a novel antifungal cyclic depsipeptide from Glomospora sp. II. Structure elucidation.

The structure of glomosporin, an antifungal antibiotic, was elucidated by NMR and MS spectroscopic studies. Glomosporin is a novel cyclic depsipeptide with an amino acid sequence Ser-Ala-Asp-Asn-Asn-Ser-Thr, and a 3,4-dihydroxy-4-methylhexadecanoic acid side chain.

Elucidation of structure and stereochemistry of myriocin. A novel antifungal antibiotic.
