Ribavirin-13C5is intended for use as an internal standard for the quantification of ribavirin by GC- or LC-MS. Ribavirin is an antiviral guanosine nucleoside analog.1,2Upon entry into cells, ribavirin is metabolized to an active triphosphate form that induces viral RNA chain termination and inhibits viral polymerases. It reduces replication in a panel of seven RNA and four DNA viruses in Vero cells (EC50s = 2-95 μg/ml).3Ribavirin also reduces replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Vero cells (EC50= 109.5 μM).4Aerosol administration of ribavirin (30 mg/kg) reduces mortality in a mouse model of influenza A infection.5Formulations containing ribavirin have been used in the treatment of respiratory syncytial virus (RSV), hepatitis C virus (HCV), and viral hemorrhagic fevers. 1.Gilbert, B.E., and Knight, V.Biochemistry and clinical applications of ribavirinAntimicrob.

Deleobuvir sodium is the salt form of Deleobuvir, also known as BI207127, a non-nucleoside hepatitis C virus NS5B polymerase inhibitor for the treatment of hepatitis C. Deleobuvir was tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including faldaprevir. Deleobuvir showed that a triple combination of deleobuvir, faldaprevir, and ribavirin performed well in HCV genotype 1b patients. Efficacy fell below 50%, however, for dual regimens without ribavirin and for genotype 1a patients. In December 2013, deleobuvir was discontinued since recent findings from phase III trials did not suggest sufficient efficacy.
