Title: The application of the phosphoramidate ProTide approach confers micromolar potency against hepatitis C virus on inactive agent 4'-azidoinosine: kinase bypass on a dual base/sugar modified nucleoside. Author: McGuigan C, Daverio F, Nájera I, Martin JA, Klumpp K, Smith DB. Journal: Bioorg Med Chem Lett; 2009 Jun 01; 19(11):3122-4. PubMed ID: 19398331. Abstract: Novel phosphoramidate ProTides derived from 4'-azidoinosine have been prepared and evaluated in the replicon assay against hepatitis C Virus (HCV). The parent nucleoside analogue is inactive in this assay, while the ProTides are active at low microM levels in some cases. This is a rare example of an inosine nucleoside analogue with potent antiviral activity and further supports the notion of ProTides as a drug discovery motif.[Abstract] [Full Text] [Related] [New Search]
