Published: August 2008

In order to study the effect of 5'-modification of 2'-deoxynucleoside on its anti-HCV activity, several analogues were synthesized and evaluated. Among the analogues, a 5'-deoxy-5'-phenacylated analogue exhibited a good anti-HCV activity with an EC(50) of 15.1 microM. This compound is expected to operate via a type of mechanism that does not involve a generally known 5'-O-triphosphorylation process.
