Synthesis and Biological Evaluation of 4′-C-Methyl Nucleosides
摘要:
A series of 2'-deoxy, 2',3'-unsaturated and 2',3'-dideoxynucleoside analogues, which have an additional methyl group at the 4'-position, have been synthesized. When evaluated for their inhibitory activity against HIV in MT-4 cell, 2'-deoxy-4'-C-methyl nucleosides exhibited potent activity.
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.

medicinal and biological chemistry is contrasted by the challengingsynthetic access to these molecules and the lack of efficient diversification strategies. Herein, we report the development of a biocatalytic diversification approach based on nucleoside phosphorylases, which allows the straightforward installation of a variety of pyrimidine and purine nucleobases on a 4′-alkylated sugar scaffold.
