Favipiravir (T-705) (CAS 259793-96-9) is one of the 5 compounds recommended by WHO for the investigation of treatment of COVID-19.
Favipiravir (T-705) 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. Favipiravir is a broad-spectrum antiviral drug that was cleared by the Drugs Controller General of India (DCGI) last week for “emergency restricted” use among Covid-19 patients. Favipiravir was originally developed in the late 1990s by a company that was later purchased by the Japanese firm Fujifilm as part of its transition from the photo business to healthcare. After being tested against a range of viruses, the drug was approved in Japan in 2014 for emergency use against flu epidemics or to treat new strains of influenza.
