Discovery of a biologically active thiostrepton fragment

J Am Chem Soc. 2005 Nov 2;127(43):15042-4. doi: 10.1021/ja0552803.

Abstract

Design, synthesis, and biological evaluation of several domains of the thiopeptide antibiotic thiostrepton led to the discovery of a biologically active fragment. The biological properties of this novel small organic molecule include antibiotic activity against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VREF) bacterial strains, as well as cytotoxic action against a number of cancer cell lines.
