Common NamePlusbacin A3
DescriptionPlusbacin A3 is a depsipeptide antibiotic that exhibits significant antibacterial activity, particularly against vancomycin-resistant bacteria. Its total synthesis has been achieved through solid-phase peptide synthesis (SPPS), involving peptide elongation on a solid support, followed by cleavage from the resin, macrolactamization, and global deprotection (PMID:35293208 ). The compound's structure and conformation have been studied using advanced NMR techniques, revealing its binding interactions with the cell walls of Staphylococcus aureus, where it contacts the peptidoglycan layer and membrane components (PMID:28135800 ). These interactions suggest a dual mode of action: first, plusbacin A3 disrupts the peptidoglycan layer closest to the membrane, inhibiting chain extension via transglycosylation; second, it may thin and disrupt the membrane, potentially affecting ATP-binding cassette transporters (PMID:28135800 ). The detailed synthetic studies and biological implications of plusbacin A3 highlight its potential as a therapeutic agent against resistant bacterial strains (PMID:29457732 ; PMID:17371023 ).
