developed with highly stable and conformationally constrained macrocyclic components that replace tripeptide segments of protease substrates. Each compound inhibits both HIV-1 protease and viral replication (HIV-1, HIV-2) at nanomolar concentrations without cytotoxicity to uninfected cells below 10 microM. Their activities against HIV-1 protease (K(i) 1.7 nM (1), 0.6 nM (2), 0.3 nM (3)) are 1-2 orders of
已经开发了三种新的拟肽(1-3),它们具有高度稳定且受构象约束的大环组分,可替代蛋白酶底物的三肽片段。每种化合物均以纳摩尔浓度抑制HIV-1蛋白酶和病毒复制(HIV-1,HIV-2),而对10 microM以下的未感染细胞无细胞毒性。它们对HIV-1蛋白酶的活性(K(i)1.7 nM(1),0.6 nM(2),0.3 nM(3))比其对HIV-1感染的原发性外周血的抗病毒能力高1-2个数量级血液单核细胞(IC(50)45 nM(1),56 nM(2),95 nM(3))或感染HIV-1的MT2细胞(IC(50)90 nM(1),60 nM(2) ),说明细胞摄取不足。但是,在相同条件下,它们的抗病毒能力类似于茚地那韦和氨普那韦。它们在感染的MT2细胞中抑制HIV-1和HIV-2复制的能力存在显着差异,其中1种对HIV-2无效,而2种对两种病毒均有效。证据表明1和2抑制HIV-1结构蛋白
