Introducing purine bases to P2-ligands might enhance the potency of Human Immunodeficiency Virus-1 (HIV-1) protease inhibitory because of the carbonyl and NH groups promoting the formation of extensive H-bonding interactions. In this work, thirty-three compounds are synthesized and evaluated, among which inhibitors 16a, 16f and 16j containing N-2-(6-substituted-9H-purin-9-yl)acetamide as the P2-ligands along
将嘌呤碱基引入P2-配体可能会增强人类免疫缺陷病毒1(HIV-1)蛋白酶抑制的效力,因为羰基和NH基团促进了广泛的H键相互作用的形成。在这项工作中,合成和评估了33种化合物,其中含有N-2-(6-取代的9H-嘌呤-9-基)乙酰胺作为P2-配体以及4-甲氧基苯基磺酰胺的抑制剂16a,16f和16j作为P2'-配体,分别在体外对IC50的IC50浓度为43 nM,42 nM和68 nM表现出有效的抑制作用。
