  β-D-和L-2'-DEOXY-2'-氟代糖核苷的合成和体外抗HCV活性

  摘要：

  基于 β-D-2'-deoxy-2'-fluorocytidine 作为一种有效的抗丙型肝炎病毒 (HCV) 药物的发现，一系列 β-D- 和 l-2'-deoxy-2'-fluororibonucleosides合成了在 5 和/或 4 位进行修饰的 HCV，并评估了它们对 HCV 和牛病毒性腹泻病毒 (BVDV) 的体外活性。2'-氟基团的引入是通过用氟化氢-吡啶或氟化钾对 2,2'-脱水核苷进行氟化，或用 DAST 对阿拉伯核苷进行氟化来实现的。在合成的 27 个类似物中，只有 5-氟化合物，即 β-D-2'-deoxy-2',5-difluorocytidine (5) 在亚基因组 HCV 复制子细胞系中具有抗 HCV 活性，并且对核糖体 RNA。由于 β-D-N4-羟基胞苷 (NHC) 先前已显示出有效的抗 HCV 活性，N4-羟基和 2'-氟的两个官能团结合成一个分子，产生 β

  of the N(4)-hydroxyl and the 2'-fluoro into one molecule, resulting (2'R)-d-2'-deoxy-2'-fluoro-N(4)-hydroxycytidine (23). However, this nucleoside showed neither anti-HCV activity nor toxicity. All the l-forms of the analogues were devoid of anti-HCV activity. None of the compounds showed anti-BVDV activity, suggesting that the BVDV system cannot always predict anti-HCV activity.

  基于发现（2'R）-d-2'-deoxy-2'-氟胞苷作为有效的抗丙型肝炎病毒（HCV）剂，一系列d-和1-2'-deoxy-2'合成了具有5-和/或4-位修饰的-氟核糖核苷，并评估了其抗HCV和牛病毒性腹泻病毒（BVDV）的体外活性。合成中的关键步骤，即2'-氟基团的引入是通过用氟化氢-吡啶或氟化钾对2,2'-脱水核苷进行氟化，或用DAST对阿拉伯糖核苷进行氟化来实现的。在合成的27个类似物中，只有5-氟化合物，即（2'R）-d-2'-deoxy-2'，5-difluorocytidine（13），显示出有效的抗HCV活性和对核糖体RNA的毒性。用硫醇基取代4-氨基会导致活性降低，而4-甲硫基取代的类似物（25）会抑制核糖体RNA。由于N（4）-羟基胞嘧啶核苷（NHC）先前显示出有效的抗HCV活性，我们将N（4）-羟基和2'-氟的两个功能合并为一个分子，得到（2'R）-d -2'-脱氧-

  The present invention relates to methods of synthesizing 18 F-FMAU. In particular, 18 F-FMAU is synthesized using one-pot reaction conditions in the presence of Friedel-Crafts catalysts. The one-pot reaction conditions are incorporated into a fully automated cGMP-compliant radiosynthesis module, which results in a reduction in synthesis time and simplifies reaction conditions. The one-pot reaction conditions are also suitable for the production of 5-substitued thymidine or cytidine analogues. The products from the one-pot reaction (e.g. the labeled thymidine or cytidine analogues) can be used as probes for imaging tumor proliferative activity. More specifically, these [ 18 F]-labeled thymidine or cytidine analogues can be used as a PET tracer for certain medical conditions, including, but not limited to, cancer disease, autoimmunity inflammation, and bone marrow transplant.
