✦ Synopsis
A new antibiotic, active against Gram-positive bacteria, has been isolated from the fermentation broth of the actinomycete Amycolatopsis sp. ST 101170. The structure of the compound named vancoresmycin, a tetramic acid derivative with a highly oxygenated long alkyl chain, was elucidated by extensive spectroscopic studies and derivatization.

The major antibiotic constituent, xanthobaccin A, was isolated from broth cultures of Stenotrophomonas sp. strain SB-K88 as a major antifungal substance. The structure elucidation by spectroscopic analyses and chemical conversion revealed it to be a new tetramic acid-containing macrocyclic lactam.
