Resormycin, a Novel Herbicidal and Antifungal Antibiotic Produced by a Strain of Streptomyces platensis

II. Structure Elucidation of Resormycin

Abstract

A novel herbicidal antibiotic, resormycin, was isolated from the culture broth of Streptomyces platensis MJ953-SF5.
The structure of resormycin is determined to be (2Z)-2-N-[2N-[(3S)-3, 6-diaminoheptanoyl](2S)-3-hydroxyvalyl]amino-3-(4-chloro-3, 5-dihydroxy)phenylpropenoic acid by spectroscopic analyses, degradation studies and X-ray crystallography.
