Enantiomers 8R, 11R, and 12R were inactive against the HIV‐1 strain IIIB. Hydrazones 8S, 11S, and 12S which were active against HIV‐1 wild type showed no inhibition against a double mutant NNRTI‐resistant strain (K103N;Y181C). Molecular docking calculations of R‐ and S‐enantiomers of 8, 11, and 12 were performed using the hydrazone‐bound novel site of HIV‐1 RT.
根据我们的抗病毒药物开发尝试,合成了带有氨基酸侧链的酰腙衍生物,以评估它们对各种病毒的抗病毒活性。在这些化合物中,8S、11S 和 12S 显示出抗 HIV-1 活性,抑制浓度为 50% (IC50) = 123.8 µM(选择性指数,SI > 3),IC50 = 12.1 µM(SI > 29),IC50 =分别为 17.4 µM (SI > 19)。对映异构体 8R、11R 和 12R 对 HIV-1 毒株 IIIB 无活性。对 HIV-1 野生型有活性的腙 8S、11S 和 12S 对双突变 NNRTI 抗性菌株(K103N;Y181C)没有抑制作用。使用 HIV-1 RT 的腙结合新位点,对 8、11 和 12 的 R-和 S-对映异构体进行了分子对接计算。
