设计、合成并评价了一类含不同柔性大环P1′-P2′链的HIV-1蛋白酶抑制剂。具有吡咯烷酮衍生的大环的抑制剂5a表现出有利的酶抑制和抗病毒活性(Ki = 13.2 nM,IC 50 = 22 nM)。在大环骨架中进一步引入杂原子提供了大环抑制剂5 m和5 o。这些化合物显示出优异的HIV-1蛋白酶抑制活性(Ki分别为62 pM和14 pM)和抗病毒活性(IC 50分别为5.3 nM和2.0 nM)。抑制剂5 o对耐DRV的HIV-1变种也仍然非常有效。
Design, synthesis, and evaluation of a new class of HIV-1 protease inhibitors containing diverse flexible macrocyclic P1′–P2′ tethers are reported. Inhibitor 5a with a pyrrolidinone-derived macrocycle exhibited favorable enzyme inhibitory and antiviral activity (Ki = 13.2 nM, IC50 = 22 nM). Further incorporation of heteroatoms in the macrocyclic skeleton provided macrocyclic inhibitors 5m and 5o. These compounds showed excellent HIV-1 protease inhibitory (Ki = 62 pM and 14 pM, respectively) and antiviral activity (IC50 = 5.3 nM and 2.0 nM, respectively). Inhibitor 5o also remained highly potent against a DRV-resistant HIV-1 variant.
