  Synthesis and Structure−Activity Relationships of Novel Anti-hepatitis C Agents: N³,5‘-Cyclo-4-(β-d-ribofuranosyl)-vic-triazolo[4,5-b]pyridin-5-one Derivatives

  摘要：

  Several 6- and 7-monosubstituted N-3 5'-cyclo-4-(beta-D-ribofuranosyl)-vic-triazolo[4,5-b]pyridin5-one derivatives as well as the 5-thiono analogue were synthesized, providing structure-anti-hepatitis C virus (HCV) activity relationships for the series. Among the compounds synthesized, the 6-bromo, 7-methylamino, and 5-thiono analogues exhibited more potent anti-HCV activity in an HCV subgenomic replicon cell based assay (EC90 = 1.9, 7.4, and 10.0 mu M, respectively) than the lead compound N-3, 5'-cyclo-4-(beta-D-ribofuranosyl)-vic-triazolo [4,5-b] pyridin-5-one (EC90 = 79.8 mu M).

  We recently discovered a novel compound, identified as N-3,5'-cyclo-4-(beta-D-ribofuranosyl)-victriazolo[4,5-b]pyridinin-5-one, with anti-hepatitis C virus (HCV) activity in vitro. The structure was confirmed by chemical synthesis from 2-hydroxy-5-nitropyridine. It showed anti-HCV activity with EC50 = 19.7 mu M in replicon cells. Its 3'-deoxy sugar analogue was also synthesized, but was inactive against HCV in vitro.
