2’-Fluoro-2’-deoxycytidine inhibits murine norovirus replication and synergizes MPA, ribavirin and T705
Noroviruses are the main causative agents of acute viral gastroenteritis worldwide. However, no vaccine or specific antiviral treatment is available, imposing a heavy global health burden. The nucleoside analogue 2’-fluoro-2’-deoxycytidine (2’-FdC) has been reported to have broad antiviral activity. Here, we report that 2’-FdC significantly inhibits murine norovirus replication in macrophages. This effect was partially reversed by exogenous supplementation of cytidine triphosphate. The combination of 2’-FdC with mycophenolic acid, ribavirin or favipiravir (T705) exerts synergistic antiviral effects. These results indicate that 2’-FdC is a potential candidate for antiviral drug development against norovirus infection.
