2'-Fluoro-2'-deoxycytidine inhibits murine norovirus replication and synergizes MPA, ribavirin and T705.


ABSTRACT: 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.
