Abstract

We recently discovered a novel compound, identified as N ³,5′-cyclo-4-(β-D-ribofuranosyl)-vic-triazolo[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 μM in replicon cells. Its 3′-deoxy sugar analogue was also synthesized, but was inactive against HCV in vitro.
