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.

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.

In order to evaluate their antiviral properties, a series of 4'-C-methyl-beta-D-ribofuranosyl purine and pyrimidinenucleosides has been prepared. Unfortunately, none of these 4'-branched nucleosides showed any antiviral activity or cytotoxcity when tested against HIV, HBV, and Yellow Fever virus.

2′ and 3′-Prodrugs of 1′, 2′, 3′ or 4′-branched β-D or β-L nucleosides, or their pharmaceutically acceptable salts and derivatives are described, which are useful in the prevention and treatment of Flaviviridae infections and other related conditions. These modified nucleosides provide superior results against flaviviruses and pestiviruses, including hepatitis C virus and viruses generally that replicate through an RNA dependent RNA reverse transcriptase. Compounds, compositions, methods and uses are provided for the treatment of Flaviviridae infection, including HCV infection, that include the administration of an effective amount of the prodrugs of the present invention, or their pharmaceutically acceptable salts or derivatives. These drugs may optionally be administered in combination or alteration with further anti-viral agents to prevent or treat Flaviviridae infections and other related conditions.
