Abstract: Oligonucleotides with a novel sugar-phosphate backbone containing at least one internucleoside 3?-NHP(O)(S?)O-5? linkage, and methods of synthesizing and using the inventive oligonucleotides are provided. The inventive thiophosphoramidate oligonucleotides were found to retain the high RNA binding affinity of the parent oligonucleotide N3??P5? phosphoramidates and to exhibit a much higher acid stability.

Abstract: A reusable linker arm for solid support oligonucleotide synthesis, the linker arm comprising formula (a) wherein Z is a linker moiety and T is an organic radical.

Abstract: The present invention provides nucleoside compounds and certain derivatives thereof which are inhibitors of RNA-dependent RNA viral polymerase. These compounds are inhibitors of RNA-dependent RNA viral replication and are useful for the treatment of RNA-dependent RNA viral infection. They are particularly useful as inhibitors of hepatitis C virus (HCV) NS5B polymerase, as inhibitors of HCV replication, and/or for the treatment of hepatitis C infection. The invention also describes pharmaceutical compositions containing such nucleoside compounds alone or in combination with other agents active against RNA-dependent RNA viral infection, in particular HCV infection. Also disclosed are methods of inhibiting RNA-dependent RNA polymerase, inhibiting RNA-dependent RNA viral replication, and/or treating RNA-dependent RNA viral infection with the nucleoside compounds of the present invention.

Abstract: The present invention discloses a method for treating HIV that includes administering ?-D-D4FC or its pharmaceutically acceptable salt or prodrug to a human in need of therapy in combination or alternation with a drug that induces a mutation in HIV-1 at a location other than the 70(K to N), 90 or the 172 codons of the reverse transcriptase region. Also disclosed is a method for using ?-D-D4FC as “salvage therapy” to patients which exhibit drug resistance to other anti-HIV agents. ?-D-D4FC can be used generally as salvage therapy for any patient which exhibits resistance to a drug that induces a mutation at other than the 70(K to N), 90 or the 172 codons.
