Six novel phosphoramidate prodrugs of uridine analogues, with structural modifications introduced at the 6- and 2′,6-positions, have been prepared and evaluated for selective antiviral activity against hepatitis C virus, as well as other positive-stranded RNA viruses. An analysis of the conformational properties of the parent nucleosides was carried out using two-dimensional NMR spectroscopy based experiments, highlighting a 3′-endo (North) sugar puckering preference and syn orientation.

Abstract
Six novel phosphoramidate prodrugs of uridine analogues, with structural modifications introduced at the 6- and 2′,6-positions, have been prepared and evaluated for selective antiviral activity against hepatitis C virus, as well as other positive-stranded RNA viruses. An analysis of the conformational properties of the parent nucleosides was carried out using two-dimensional NMR spectroscopy based experiments, highlighting a 3′-endo (North) sugar puckering preference and syn orientation.File in questo prodotto:
