In order to improve the oral bioavailability of Adenine 9-β-D-arabinofuranoside (Vidarabine, also called ara A), an antiviral drug which is active against herpes simplex and varicella zoster viruses and the first agent to be licensed for the treatment of
The arsenolysis reaction in the biotechnological method of synthesis of modified purine β-D-arabinonucleosides

We found a unique property of E. coli purine nucleoside phosphorylases to selectively perform the arsenolysis reaction of ribonucleosides in their active site without affecting β-D-arabinonucleosides. In the synthesis of modified β-D-arabinonucleosides from the corresponding ribonucleosides, the catalytical amount of sodium arsenate in the transglycosylation reaction provided a 95 to 98% conversion rate. Such an approach was shown to simplify the composition of the reaction mixtures and facilitate the isolation of the target nucleosides, particularly, vidarabine, fludarabine, and nelarabine.
Nucleoside derivatives as inhibitors of RNA-dependent RNA viral polymerase

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.
