Enopeptin A

Enopeptin A, originally isolated from a culture broth of Streptomyces sp. RK-1051, is a depsipeptide antibiotic that contains two unusual amino acids (N-methylalanine and 4-methylproline) and features a pentaenone side chain. It is effective against Gram-positive bacteria, including methicillin-resistant S. aureus (MIC = 25 µg/ml), and Gram-negative bacteria, including mutant forms of E. coli and P. aeruginosa (MICs = 200 µg/ml), however, it is not inhibitory to fungi.Formal Name: (4R)-N-[(2E,4E,6E,8E,10E)-12-[(2-hydroxy-5-oxo-1-cyclopenten-1-yl)amino]-1,12-dioxo-2,4,6,8,10-dodecapentaen-1-yl]-L-phenylalanyl-L-seryl-L-prolyl-L-proline, (6->2)-lactone.
