  异碱基修饰的2'-C-甲基核糖核苷作为丙型肝炎病毒RNA复制抑制剂的构效关系。

  摘要：

  丙型肝炎病毒感染构成了重要的健康问题，需要更有效的治疗方法。我们最近确定2'-C-甲基腺苷和2'-C-甲基鸟苷是体外HCV RNA复制的有效核苷抑制剂。但是，这两种化合物都具有明显的局限性。发现2'-C-甲基腺苷易于通过腺苷脱氨酶和嘌呤核苷磷酸化酶进行酶促转化，并且在大鼠中显示出有限的口服生物利用度。另一方面，2'-C-甲基鸟苷既没有被有效地吸收到细胞中，也没有被磷酸化。作为解决这些限制的尝试的一部分，我们现在报告一系列异碱基修饰的2'-C-甲基核糖核苷的合成和评估。该系列核苷中的结构活性关系揭示了4-氨基-7-（2-C-甲基-β-d-呋喃呋喃糖基）-7H-吡咯并[2,3-d]嘧啶和4-氨基-5-氟-7-（2-C-甲基-β-d-呋喃呋喃糖基）-7H-吡咯并[2,3-d]嘧啶是有效且无细胞毒性的HCV RNA复制抑制剂。4-氨基-7-（2-C-甲基-β-d-呋喃呋喃糖基）-7H-吡咯并[2,

  Discovery of 2′-α-C-Methyl-2′-β-C-fluorouridine Phosphoramidate Prodrugs as Inhibitors of Hepatitis C Virus

  摘要：

  2'-alpha-C-Methyl-2'-beta-C-fluorouridine and its phosphoramidate prodrugs were synthesized and evaluated for their inhibitory activity against HCV. The structure-activity relationship analysis of the phosphoramidate moiety found that 17m, 17q, and 17r exhibit potent activities against HCV, with EC50 values of 1.82 +/- 0.19, 0.88 +/- 0.12, and 2.24 +/- 0.22 mu M, respectively. The docking study revealed that the recognition of the 2'-beta-F by Arg158, 3'-OH by N291, and the Watson Crick pairing with the template allowed 23 to form the in-line conformation necessary for its incorporation into the viral RNA chain.
