A novel class of potent aminopeptidase N inhibitors with 3-amino-cyclic-imide scaffold is described. The preliminary biological test revealed that all the compounds displayed high specific inhibitory activity against aminopeptidase N compared with previous work because of the existence of free amino group. Compounds containing hydroxamate group are more potent than carboxyl and ester derivatives. Compound
描述了一种新型的具有3-氨基-环-酰亚胺支架的有效的氨基肽酶N抑制剂。初步的生物学测试表明,由于存在游离氨基,因此与以前的研究相比,所有化合物均对氨肽酶N表现出较高的特异性抑制活性。含有异羟肟酸酯基团的化合物比羧基和酯衍生物更有效。化合物13f潜在抑制APN活性,IC 50值为1.8μM,并在细胞测定和体内抗转移测定中显示出比活分布。
