A series of novel 2-phenylindole analogs were synthesized and evaluated for activity in subgenomic HCV replicon inhibition assays. Several compounds containing small alkyl sulfonamides on the phenyl ring exhibiting submicromolar EC50 values against the genotype 1b replicon were identified. Among these, compound 25d potently inhibited the 1b replicon (EC50 = 0.17 μM) with 147-fold selectivity with respect
合成了一系列新颖的2-苯基吲哚类似物,并在亚基因组HCV复制子抑制试验中评估了其活性。鉴定了几种在苯环上含有小烷基磺酰胺的化合物,它们相对于基因型1b复制子表现出亚微摩尔EC 50值。其中, 相对于细胞毒性,化合物25d有效抑制1b复制子(EC 50 = 0.17μM),选择性为147倍。化合物25d在人肝微粒体存在下稳定,在大鼠中具有良好的药代动力学特征,IV半衰期为4.3小时,口服生物利用度(F)为58%。
