Chemical analysis of a marine-derived Streptomyces sp. (CMB-M0392) isolated from sediment collected off Heron Island, Queensland, Australia, yielded a new benzothiazine ansamycin, heronamycin A. The absolute stereostructure of heronamycin A was determined by detailed spectroscopic analysis and Xray crystallography. Heronamycin A exhibited modest antimicrobial activity against Bacillus subtilis strains ATCC 6051 and 6633 (IC50 = 18 and 14 mu M, respectively). (C) 2011 Elsevier Ltd. All rights reserved.
