A series of aminopeptidase inhibitors with cyclic-imide scaffold are described. The biological characterization for the piperidinedione analogues revealed that most compounds displayed high inhibitory activity against APN. Among which 4l and 6 showed potent inhibition against APN with the IC50 value of 5.2 μM and 3.1 μM, respectively. In addition, 6 also displayed good activity in HL-60 cell assay
描述了具有环酰亚胺支架的一系列氨基肽酶抑制剂。哌啶二酮类似物的生物学特性表明,大多数化合物显示出对APN的高抑制活性。其中4l和6表现出对APN的有效抑制作用,IC 50值分别为5.2μM和3.1μM。此外,6在HL-60细胞测定和体内抗转移测定中也显示出良好的活性。这种有趣的活性特征还可以指导设计具有“单锌”活性位点的靶哺乳动物氨肽酶的新型特异性抑制剂。
