Hepatitis C virus (HCV) NS5B polymerase is a prime target for the development of direct-acting antiviral drugs for the treatment of chronic HCV infection. Several novel and potent HCV NS5B non-nucleoside inhibitors with unique tetracyclic bezonfuran-based structures were prepared and evaluated. Similar to clinical developmental compound MK-8876, N-linked (compounds 1 and 2) and C-linked (compounds
丙型肝炎病毒 (HCV) NS5B 聚合酶是开发用于治疗慢性 HCV 感染的直接作用抗病毒药物的主要目标。制备并评估了几种具有独特四环苯并呋喃基结构的新型强效 HCV NS5B 非核苷抑制剂。与临床开发化合物 MK-8876 相似,N 连接(化合物 1 和 2)和 C 连接(化合物 3 和 4)四环结构保持广谱抗复制子效力曲线,并在整个药物中表现出中等至优异的口服生物利用度和药代动力学参数三种临床前动物物种。为了更好地了解与泛基因型效力谱相关的四环结构的重要性,特别是针对临床相关的 GT1a 变体,
