isopropyl was the best side chain. Replacement of the isobutyl substituent at P1′group with phenyl substituent decreased the inhibitory potency. One of the most potent inhibitor, compound 23 showing high affinity to HIV‐1 protease with an IC50 value of 5 nm, also exhibited good anti‐SIV activity (EC50 = 0.8 μm) with low toxicity (TC50 > 100 μm). The flexible docking of inhibitor 23 to HIV‐1 protease active
合成了一系列基于(羟乙基氨基)-磺酰胺类异构体的新型HIV-1蛋白酶抑制剂,该抑制剂结合了取代的苯基和带有丰富氢键受体作为P 2配体的苯并杂环衍生物。延长将苄环与羰基连接的链导致部分结合亲和力损失。在P 1- P 2键的-CH 2-侧链中引入适当大小的小烷基取代基可提高抑菌效力,在本研究中,异丙基是最佳的侧链。用苯基取代基取代P 1 '基上的异丁基取代基降低了抑制能力。最有效的抑制剂之一,化合物23示出了具有集成电路的高亲和性HIV-1蛋白酶50的5的n值米,也显示出良好的抗SIV活性(EC 50 = 0.8μ米具有低毒性(TC)50 > 100μ米)。抑制剂23与HIV-1蛋白酶活性位点的灵活对接使与蛋白酶的相互作用合理化。
