  Synthesis of 2′-O,4′-C-alkylene-bridged ribonucleosides and their evaluation as inhibitors of HCV NS5B polymerase

  摘要：

  The synthesis of 2'-O,4'-C-methylene-bridged bicyclic guanine ribonucleosides bearing 2'-C-methyl or 5'C-methyl modifications is described. Key to the successful installation of the methyl functionality in both cases was the use of a one-pot oxidation-Grignard procedure to avoid formation of the respective unreactive hydrates prior to alkylation. The 2'-C-methyl- and 5'-C-methyl-modified bicyclic guanosines were evaluated, along with the known uracil-, cytosine-, adenine-, guanine-LNA and guanine-ENA nucleosides, as potential antiviral agents and found to be inactive in the hepatitis C virus (HCV) cell-based replicon assay. Examination of the corresponding nucleoside triphosphates, however, against the purified HCV NS5B polymerase indicated that LNA-G and 2'-C-methyl-LNA-G are potent inhibitors of both 1b wild type and S282T mutant enzymes in vitro. Activity was further demonstrated for the LNA-G-triphosphate against HCV NS5B polymerase genotypes 1a, 2a, 3a and 4a. A phosphorylation by-pass prodrug strategy may be required to promote anti-HCV activity in the replicon assay. (C) 2014 Elsevier Ltd. All rights reserved.
