title: Base-modified ribonucleosides as potential anti-hepatitis C virus agents.
abstract: Four novel series of base modified ribonucleoside analogues were synthesized and evaluated as potential anti-HCV agents. For two compounds notable anti-HCV activity was observed The triphosphates of bicyclic pyrimidine ribonucleosides were studied as substrates/inhibitors of HCV RNA-dependent RNA polymerase (RdRp, NS5B protein) and RNA helicase/NTPase (NS3 protein).
