antibiotic feglymycin was performed by solution‐phase peptide synthesis to assess the significance of individual aminoacidsidechains for its biological activity. Antibacterial activity against Staphylococcus aureus and the inhibition of enzymes MurA and MurC depend on different aminoacids.

An adaptable approach: The first highly convergent stereoselective synthesis of feglymycin (see structure) and its enantiomer is based on the coupling of repeating peptide fragments. The use of weakly basic conditions throughout the synthesis suppressed the epimerization of sensitive aryl glycine units. Feglymycin has strong anti‐HIV activity as well as potent (previously identified as weak) antibacterial
