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
报道了设计,合成和评估一类新型的HIV-1蛋白酶抑制剂,其包含多种柔性大环P1'-P2'系链。具有吡咯烷酮衍生的大环的抑制剂5a表现出良好的酶抑制和抗病毒活性(K i = 13.2 nM,IC 50 = 22 nM)。在大环骨架中进一步掺入杂原子可提供大环抑制剂5m和5o。这些化合物显示出出色的HIV-1蛋白酶抑制性(分别为K i = 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5o 它还对DRV耐药的HIV-1变异株具有很高的效力。
