Ribavirin | Antiviral guanosine ribonucleoside analog

Ribavirin is a clinically useful antiviral medication for Hepatitis C, viral hemorrhagic fevers and other RNA and DNA viruses. The exact mechanism of its antiviral activity is uncertain. Various proposals include inhibition of viral polymerase1, RNA mutagenesis2, and inosine monophosphate dehydrogenase (IMPDH) inhibition3. Sensitizes tumor cells to anticancer agents 5-fluorouracil5 and doxorubicin6 via inhibition of eIF4E. Displays efficacy against atypical teratoid/rhabdoid tumors7 and inhibits glioma cell growth8.
