FGI-103

FGI-103 is an antiviral drug developed as a potential treatment for the filoviruses Ebola virus and Marburg virus. In tests on mice FGI-103 was effective against both Ebola and Marburg viruses when administered up to 48 hours after infection. The mechanism of action of FGI-103 has however not yet been established, as it was found not to be acting by any of the known mechanisms used by similar antiviral drugs.
