  An Improved Transient Method for the Synthesis ofN-Benzoylated Nucleosides

  摘要：

  The Jones' transient method for the synthesis of N-benzoylated nucleosides is improved by reducing the amounts of chlorotrimethylsilane (TMSCI) and benzoyl chloride to nearly equivalent quantities. The easy work-up and high yields of products are the major advantages of this approach. Jones' method is further simplified by omitting the addition of ammonium hydroxide. The utility of this modification for the preparation of some useful protected nucleosides is also presented.

  A series of 4'-substituted ribonucleoside derivatives has been prepared and evaluated for inhibition of hepatitis C virus (HCV) RNA replication in cell culture. The most potent and non-cytotoxic derivative was compound 28 (4'-azidocytidine, R1479) with an IC(50) of 1.28 microM in the HCV replicon system. The triphosphate of compound 28 was prepared and shown to be an inhibitor of RNA synthesis mediated

  制备了一系列的4'-取代核糖核苷衍生物，并评估了其在细胞培养中对丙型肝炎病毒（HCV）RNA复制的抑制作用。最有效和无细胞毒性的衍生物是化合物28（4'-叠氮基吡啶，R1479），在HCV复制子系统中的IC（50）为1.28 microM。制备了化合物28的三磷酸酯，并显示出它是由NS5B（IC（50）= 320 nM）介导的RNA合成抑制剂，NS5B是HCV编码的RNA聚合酶。有关类似物的数据已被用来对这一系列核苷的活性产生一些初步的要求。
