Immunomodulating polynucleotides are disclosed. The immunomodulating polynucleotides may contain 5-modified uridine, 5-modified cytidine, a total of from 6 to 16 nucleotides, and/or one or more abasic spacers and/or internucleoside phosphotriesters. Also disclosed are conjugates containing a targeting moiety and one or more immunomodulating polynucleotides. The immunomodulating polynucleotides and conjugates may further contain one or more auxiliary moieties. Also disclosed are compositions containing the immunomodulating polynucleotides or the conjugates containing one or more stereochemically enriched internucleoside phosphorothioates. Further disclosed are pharmaceutical compositions containing the immunomodulating polynucleotides or the conjugates and methods of their use.

A series of novel 2′-deoxy-2′-α-fluoro-2′-β-C-methyl 3′,5′-cyclic phosphatenucleotide prodrug analogs were synthesized and evaluated for their in vitro anti-HCV activity and safety. These prodrugs demonstrated a 10–100-fold greater potency than the parent nucleoside in a cell-based replicon assay due to higher cellular triphosphate levels.

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. .
