title: Staphcoccomycin, a new basic macrolide antibiotic.
abstract: Staphcoccomycin (SCM) is a new member of the basic macrolide family of antibiotics which was isolated from the fermentation broth of Streptomyces sp. AS-NG 16. The production, purification and determination of physical and chemical properties of this novel metabolite have been completed. Comparison of the mass fragmentation patterns of SCM and its peracetate with those of angolamycin peracetate suggested a des-mycarosyl derivative of angolamycin. Moreover, the molecular ion peak (m/e 771) corresponded to C39H65NO14 and the 1H-NMR of SCM was also consistent with the proposed structure.
