The structure-activity relationship of HIV-1 protease (HIV-1 PR) inhibitors containing AHPBA (3-amino-2-hydroxy-4-phenylbutanoic acid) is discussed. In order to solve the problem of poor oral bioavailability, small-sized dipeptide HIV-1 protease inhibitors containing cyclic urethanes or benzamides at the P2 site were designed and prepared. The substitution patterns of the benzamides contributed significantly
讨论了含有AHPBA(3-氨基-2-羟基-4-苯基丁酸)的HIV-1蛋白酶(HIV-1 PR)抑制剂的构效关系。为了解决口服生物利用度差的问题,设计并制备了在P2位点含有环状氨基甲酸酯或苯甲酰胺的小型二肽HIV-1蛋白酶抑制剂。苯甲酰胺的取代模式对其HIV-1 PR抑制活性有显着贡献,并且表明P2残基的选择非常重要。已经鉴定出具有亚纳摩尔IC 50值并且表现出良好的抗病毒效力的高效抑制剂。在该类别中,抑制剂18最有效(IC90(CEM / HIV-1 IIIB)0.11 microM),在狗中显示出良好的口服生物利用度。
