The basical structure of diketopiperazines is a cyclic dipeptide condensed by two amino acids. Because of the stable framework of the six-member ring structure, and having two hydrogen bond donor and two hydrogen bond receptor, DKPs have become important chemical pharmacophores, with strong biological activities and pharmacological activities in the drug. A series of cyclic compounds were found from marine organisms in recent years, research showed that their functions are not limited on anti-bacterial, cyto-toxic activity, and so on, but also playing an important role in regulatory mechanism of quorum sensing as signal molecules, they have become research hot point in ecological chemistry. This paper reviewed the research progress of diketopiperazines found in the marine microbial metabolites, and the future study trends was discussed and outlooked.%二酮哌嗪类化合物的基本结构是由两个氨基酸缩合而成的环二肽,因其骨架具有稳定的六元环结构,且有两个氢键给体和两个氢键受体,使得DKPs具有较强的生物活性和药理活性,在药物化学中成为一个重要的药效团.近年来从海洋微生物中发现一系列环二肽类化合物,研究表明其功能不局限于抗菌、细胞毒活性等方面,在群体感应调控机制中也充当着信号分子的重要角色,已成为化学生态学的研究热点.本文综述了近年来二酮哌嗪类化合物在海洋微生物代谢产物中的研究进展.并对其研究方向进行了讨论和展望.
