docked into thumb II site of HCV NS5B GT4a using rigid docking approach. Eighteen compounds (7a–r) that show good docking scores were synthesized and tested in vitro against NS5B GT4a. Compounds 7b and 7n showed the best inhibitory activity (IC50 = 0.338 and 0.342 µM, respectively). Compounds 7a, 7b, 7c, 7d, 7k, 7n, 7q, and 7r that have IC50 values less than 2 µM were assessed for cellular anti-HCV GT4a
丙型肝炎病毒(HCV)基因型4a(GT4a)在埃及盛行。尽管具有很高的抵抗力,但它并没有获得必要的科学关注。由于HCV GT4a的晶体结构NS5B(RNA依赖性RNA聚合酶)到目前为止尚未解析,因此进行了同源建模以建立和验证该酶的3D模型。检测到配体结合位点,包括变构拇指II型口袋,并将其用于前导优化。虚拟设计了六十种新的4-噻唑烷酮衍生物,并使用刚性对接方法将其对接到HCV NS5B GT4a的Thumb II位点。合成了18个具有良好对接分数的化合物(7a–r),并在体外针对NS5B GT4a进行了测试。化合物7b和7n表现出最佳的抑制活性(IC50 = 0.338和0.342 µM。使用人肝癌细胞系(Huh 7.5)对IC 50值小于2 µM的化合物7a,7b,7c,7d,7k,7n,7q和7r进行了细胞抗HCV GT4a活性评估。病毒生长抑制的百分比在79.67和94.77%之间
