Enopeptin A is an unusual depsipeptide featuring a pentaenone side chain, reported as an antiviral by researchers at RIKEN in 1991. Enopeptin A has potent antibacterial activity against Gram positive and Gram negative bacteria, including MRSA. Enopeptin A is the most non-polar of the acyldepsipeptide (ADEP) antibiotics which include the recently rediscovered compounds, A54556 A and B, that act by activating and disregulating Clp-family proteins.

Enopeptin A (BRN 537924; NSC 657143) 最初从链霉菌属 RK-1051 的培养液中分离出来，是一种含有两种不常见氨基酸（N-甲基丙氨酸和 4-甲基脯氨酸）的缩肽类抗生素，并具有五烯酮侧链。它对革兰氏阳性菌（包括耐甲氧西林金黄色葡萄球菌 (MIC=25 μg/mL)）和革兰氏阴性菌（包括大肠杆菌和铜绿假单胞菌的突变体 (MIC=200 μg/mL)）有效；但是，它对真菌没有抑制作用。
