exploration and structure–activity relationship (SAR) studies led to the discovery of a new derived scaffold 2-((4-bisarylmethyl-piperazin-1-yl)methyl)benzonitrile. Several new scaffold derivatives exhibited higher in vitro anti-HCV activity at low nanomolar concentrations compared to L0909. A biological study indicated that the high potency of active derivatives 3d, 3h, and 3i was primarily driven by the
尽管现在有十几种直接作用的抗病毒 (DAA) 药物可供使用,但丙型肝炎病毒 (HCV) 治疗方案中没有病毒进入抑制剂。基于先前确定的 HCV 进入抑制剂L0909,化学空间探索和构效关系 (SAR) 研究导致发现了一种新的衍生支架 2-((4-bisarylmethyl-pirapazin-1-yl)methyl)benzonitron。与L0909相比,几种新的支架衍生物在低纳摩尔浓度下表现出更高的体外抗 HCV 活性。一项生物学研究表明,活性衍生物3d、3h和3i的高效力主要是由于对病毒进入阶段的抑制作用。此外,SPR 实验证实,这类衍生物可能靶向 HCV E1 蛋白。药代动力学研究表明,化合物3d和3i在以 15 mg/kg 的单剂量对大鼠口服给药后,在大鼠血浆中可口服且持久。总之,这项工作提供了一种新的 2-((4-bisarylmethyl-piperazin-1-yl)methyl)benzonitrile
