Functions

Favipiravir is an inhibitor of Influenza viruses A, B, and C (IC50s: A = 0.03-0.20 µg/mL H1N1, 0.01-0.30 H2N2, 0.08-0.48 H3N2, 0.14-0.15 H4N2, 0.24-1.60 H7N2, 0.20-0.82 H5N1, 0.35 H1N2; B = 0.04-0.09 µg/mL; C = 0.03-0.06 µg/mL) as well as strains resistant to adamantane-type antivirals, oseltamivir, and zanamivir. It displayed no cytotoxicity in a variety of cells. Favipiravir selectively inhibits viral RNA-dependent RNA polymerase. Favipiravir has also shown activity against other viruses including arena, phlebo, hanta, flavi, entero, alpha, respiratory syncytial, and noroviruses.
