Novel potential human immunodeficiency virus (HIV) protease inhibitors were designed by a combination of nelfinavir and amprenavir motifs. The designed compounds were prepared by a facile synthetic route and their stereochemistry was further confirmed by a stereospecific synthesis from commercially available (S)-2-oxiranylmethyl m-nitrobenzenesulfonate. All compounds were tested for their ability in
通过结合奈非那韦和安普那韦基序设计了新型潜在的人类免疫缺陷病毒(HIV)蛋白酶抑制剂。通过容易的合成路线制备设计的化合物,并且通过从商业可获得的(S)-2-环氧乙烷基甲基间硝基苯磺酸酯的立体有择合成进一步证实了它们的立体化学。用公开的参考文献19测试了所有化合物抑制HIV 1型蛋白酶活性的能力。在初步生物测定中,衍生物1a-u表现出中等至显着的抑制活性。最好的化合物1a的IC50值为0.02 microM,与氨普那韦相当。使用已发布的HIV 1型蛋白酶的X射线晶体结构对化合物1a-u进行了对接研究,所有化合物都以扩展构象与HIV 1型蛋白酶结合,并且该结合构象的支架可以很好地对齐。进行了比较分子场分析(CoMFA)研究,以探讨静电和空间效应在这些新化合物与HIV 1型蛋白酶结合中的特定作用,并建立了以13种化合物为训练集的预测CoMFA模型。对其他五种化合物作为测试集的测试分析表明,CoM
