Discovery of 2′-α-C-Methyl-2′-β-C-fluorouridine Phosphoramidate Prodrugs as Inhibitors of Hepatitis C Virus
摘要:
2'-alpha-C-Methyl-2'-beta-C-fluorouridine and its phosphoramidate prodrugs were synthesized and evaluated for their inhibitory activity against HCV. The structure-activity relationship analysis of the phosphoramidate moiety found that 17m, 17q, and 17r exhibit potent activities against HCV, with EC50 values of 1.82 +/- 0.19, 0.88 +/- 0.12, and 2.24 +/- 0.22 mu M, respectively. The docking study revealed that the recognition of the 2'-beta-F by Arg158, 3'-OH by N291, and the Watson Crick pairing with the template allowed 23 to form the in-line conformation necessary for its incorporation into the viral RNA chain.
Cyclic phosphoramidates as prodrugs of 2′-C-methylcytidine
摘要:
The currently approved treatment for hepatitis C virus infections is a combination of Ribavirin and pegylated Interferon. It leads to a sustained virologic response in approximately only half of the patients treated. For this reason there is an urgent need of new therapeutic agents. 2'-C-Methylcytidine is the first nucleoside inhibitor of the HCV NS5B polymerase that was efficacious in reducing the viral load in patients infected with HCV. The application of a monophosphate prodrug approach based on unprecedented cyclic phosphoramidates is reported. Our SAR studies led to compounds that are efficiently converted to the active triphosphate in human hepatocytes. (C) 2009 Elsevier Masson SAS. All rights reserved.
