Ribavirin-13C5 is intended for use as an internal standard for the quantification of ribavirin by GC- or LC-MS. Ribavirin (T0684) 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.
Pimodivir, also known as VX-787, JNJ-872, is a novel inhibitor of influenza virus replication that blocks the PB2 cap-snatching activity of the influenza viral polymerase complex. VX-787 binds the cap-binding domain of the PB2 subunit with a KD (dissociation constant) of 24 nM as determined by isothermal titration calorimetry (ITC). The cell-based EC50 (the concentration of compound that ensures 50% cell viability of an uninfected control) for VX-787 is 1.6 nM in a cytopathic effect (CPE) assay, with a similar EC50 in a viral RNA replication assay. VX-787 is active against a diverse panel of influenza A virus strains, including H1N1pdm09 and H5N1 strains, as well as strains with reduced susceptibility to neuraminidase inhibitors (NAIs).
Favipiravir sodium is a selective inhibitor of viral RNA-dependent RNA polymerase with activity against many RNA viruses, influenza viruses, West Nile virus, yellow fever virus, foot-and-mouth disease virus as well as other flaviviruses, arenaviruses, bunyaviruses and alphaviruses.
