Benzothiadiazine inhibitors of the HCV NS5B RNA-dependent RNA polymerase are an important class of non-nucleoside inhibitors that have received considerable attention in the search for novel HCV therapeutics. Research in our laboratories has identified a novel series of tetracyclic benzothiadiazine inhibitors of HCV polymerase bearing a benzylamino substituent on the B-ring. Compounds in this series
HCV NS5B RNA依赖性RNA聚合酶的苯并噻二嗪抑制剂是重要的一类非核苷抑制剂,在寻找新的HCV治疗剂时受到了极大的关注。我们实验室的研究已经确定了一系列新的HCV聚合酶四环苯并噻二嗪抑制剂,其在B环上带有一个苄基氨基取代基。该系列化合物在基因型1a和1b聚合酶抑制试验和亚基因组复制子试验中均表现出低纳摩尔活性。大鼠体内药代动力学特性的优化产生了化合物30,该化合物具有良好的口服生物利用度(F = 56%)和良好的组织分布药物特性,且肝/血浆比例高。化合物30在复制子检测中是强效抑制剂,针对基因型1a和1b的EC 50值分别为10和6 nM。
