Amphomycin is a natural antibacterial lipopeptide first isolated from S. canus. Lipopeptides are cyclic depsipeptides with a peptidyl side chain capped with a saturated alkyl tail. They preferentially target Gram-positive bacteria and may be useful against drug resistant strains. Amphomycin is also an inhibitor of peptidoglycan synthesis in both bacterial and mammalian systems, as it binds with phosphorylated substrates in a calcium-dependent manner.
