Molnupiravir was developed at Emory University by the university's drug innovation company, Drug Innovation Ventures at Emory (DRIVE).[6] In 2014, DRIVE began a screening project funded by the Defense Threat Reduction Agency to find an antiviral drug targeting Venezuelan equine encephalitis virus (VEEV), which led to the discovery of EIDD-1931.[12] When turned into the prodrug EIDD-2801 (molnupiravir), the compound also showed activity against other RNA viruses including influenza, Ebola, chikungunya, and various coronaviruses.[12]
They found this drug while looking for drugs to treat VEEV, but this drug was never used for that. If you follow the link to footnote 12 you get a pretty good background on this drug.
