Structure-Activity Relationships Among a New Class of Antiviral Heterosubstituted 2',3'-Dideoxynucleoside Analogues
摘要:
3'-Oxa-4'-thiocytidine nucleoside analogues 14-17 were prepared from oxathiolanes 10 and 11, and evaluated for activity against HIV-1 and HBV in vitro. The nucleoside analogues were found to possess potent activities against HIV-1 in a panel of cell lines. Compound 16 is moderately active against HBV in 2.2.15 cells.
The present invention relates to nucleoside diphosphate mimics and nucleoside triphosphate mimics, which contain diphosphate or triphosphate moiety mimics and optionally sugar-modifications and/or base-modifications. The nucleotide mimics of the present invention, in a form of a pharmaceutically acceptable salt, a pharmaceutically acceptable prodrug, or a pharmaceutical formulation, are useful as antiviral, antimicrobial, and anticancer agents. The present invention provides a method for the treatment of viral infections, microbial infections, and proliferative disorders. The present invention also relates to pharmaceutical compositions comprising the compounds of the present invention optionally in combination with other pharmaceutically active agents.

. are as defined herein. These compounds are useful as substrates for DNA/RNA polymerases, and as anti-viral agents in particular against HIV-1.
A method for the treatment of a host, and in particular, a human, infected with hepatitis B virus (HBV) is provided that includes administering an effective amount of a β-L-nucleotide, optionally in combination therapy with other drugs for the treatment of HBV or human immuno-deficiency virus (HIV).
