  β-d-2′-α-F-2′-β-C-Methyl-6-O-substituted 3′,5′-cyclic phosphate nucleotide prodrugs as inhibitors of hepatitis C virus replication: A structure–activity relationship study

  摘要：

  The 3',5'-cyclic phosphate prodrug 9-[beta-D-2'-deoxy-2'-alpha-fluoro-2'-beta-C-methylribofuranosyl]-2-amino-6-ethoxypurine, PSI-3529381, has demonstrated promising anti-HCV efficacy in vitro and in human clinical trials. A structure-activity relationship study of the nucleoside 3',5'-cyclic phosphate series of beta-D-2'-deoxy-2'-alpha-fluoro-2'-beta-C-methylribofuranosyl nucleoside prodrugs was undertaken and the anti-HCV activity and in vitro safety profile were assessed. Cycloalkyl 3',5'-cyclic phosphate prodrugs were shown to be significantly more potent as inhibitors of HCV replication than branched and straight chain alkyl 3',5'-cyclic phosphate prodrugs. No cytotoxicity and mitochondrial toxicity for prodrugs 12, 13 and 19 were observed at concentrations up to 100 mu m in vitro. Cycloalkyl esters of 3',5'-cyclic phosphate nucleotide prodrugs demonstrated the ability to produce high levels of active triphosphate in clone-A cells and primary human hepatocytes. Compounds 12, 13 and 19 also demonstrated the ability to effectively deliver in vivo high levels of active nucleoside phosphates to rat liver. (C) 2012 Elsevier Ltd. All rights reserved. .
