Also Known As: T-705, Favipiravir
Favipiravir also known as T-705 is an experimental anti-viral drug with activity against many RNA viruses. It, like some other experimental antiviraldrugs (T-1105 and T-1106), is a pyrazinecarboxamide derivative. Favipiravir is active against influenza viruses, West Nile virus, yellow fever virus, foot-and-mouth disease virus as well as other flaviviruses, arenaviruses, bunyaviruses and alphaviruses.
The mechanism of its actions is thought to be related to the selective inhibition of viral RNA-dependent RNA polymerase. Favipiravir does not inhibit RNA of DNA synthesis in mammalian cells and is not toxic to them.
