磷脂酶A2(PLA2)在很多人类疾病的病理研究中起重要作用,是药物化学研究所的热点之一。因此,发展新型的PLA2抑制剂对生物有机研究和临床应用均有重要意义。我们设计合成分泌型PLA2的非底物类似物以寻找新型PLA2抑制剂。本文基于结构设计并合成了喹啉-4-乙酰胺作为PLA2抑制剂,目标化合物结构经1^HNMR,IR,MS和元素分析确认,初步活性检测显示该类化合物具有较好体外活性及动物活性。

Phospholipase A2(PLA2) plays an important role in the pathology of a number of human diseases and is an attract target for medicinal chemistry research. Therefore, the development of novel tyep PLA2 inhibitors is of great interest for both bioorganic studies and clinical application. We focus on designing and synthesizing non- analogues of the phospholipidic substrate of sPLA2 n order to find new inhibitors. Herein, quinoline-4-acetamide sPLA2 inhibitors were designed by structure-based drug design method and synthesized. The structures of the title compounds were confirmed by elemental analysis, 1^H NMR, IR and MS. The preliminary bioassay data indicated that the title compounds display certain inhibition to sPLA2 at 10μ mol·L^-1 iv vitro, and were shown to active on animal model.
