l-alanine phosphoramidate derivatives with variations to the amino acid ester. The 1-naphthyl phosphoramidate of β-2′-methylguanosine containing the benzyl ester (20) was the most active at 0.12 μM, an 84-fold of increase in activity compared to the parent nucleoside (2) with no increase of cytotoxicity. The carboxypeptidase mediated hydrolysis of several ProTides showed a predictive correlation with their
