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).
