  Synthesis and anti-hepatitis C virus (HCV) activity of 3′-C-substituted-methyl pyrimidine and purine nucleosides

  摘要：

  On the basis of potent anti-hepatitis C virus (HCV) activity of 2'-C-hydroxymethyladenosine, 3'-C-substituted-methyl-ribofuranosyl pyrimidine and purine nucleosides were designed and synthesized from D-xylose. Among compounds tested, all adenine analogues, 4a, 4d, and 4g showed significant anti-HCV activity in a replicon-based cell assay irrespective of the substituent (Y = OH, N-3, or F) at the 3'-C-substituted methyl position, among which 4g (Y = N3) was the most potent, but it is also cytotoxic. This study guarantees the 3'-C-substituted-methyl nucleoside serves as a new template for the development of new anti-HCV agents. (C) 2010 Elsevier Ltd. All rights reserved.
