first known secondary metabolite from an anaerobic microorganism (Clostridium cellulolyticum), represents a highly potent antibiotic that is active against methicillin‐resistant Staphylococcus aureus (MRSA) and vancomycin‐resistant Enterococcus faecalis (VRE) at nanomolar concentrations. To unveil structure–activity relationships of the unusual polythioamide natural product we have designed a synthetic
natural product in which all building blocks are connected through thioamide linkages, 1 is active against multiresistant staphylococci. It is the only known secondary metabolite from a strictly anaerobicbacterium.
(nusG) in Clostridium cellulolyticum induced the biosynthesis of the novel antibiotic closthioamide and related thioamides. This is the first successful genetic engineering of an anaerobe to trigger a cryptic pathway. Furthermore, synthetic probes provide valuable insights into the biogenetic relationship of the rare thioamide metabolites.
