FGI-106 tetrahydrochloride is a potent and broad-spectrum inhibitor with inhibitory activity against multiple viruses. FGI-106 tetrahydrochloride is active against Ebola, Rift Valley and Dengue Fever viruses with EC50s of 100 nM, 800 nM and 400-900 nM, respectively. FGI-106 tetrahydrochloride also inhibits non-hemorrhagic fever viruses HCV and HIV-1 with EC50s of 200 nM and 150 nM, respectively[1].

Treatment with 2 μM FGI-106 mediated a 4 log reduction in infectious viral titers relative to matched controls, with an EC90 for inhibition of viral killing of host cells (Vero E6 cells) estimated to be 0.6 μM[1].In cell-based assays, treatment with FGI-106 inhibits viral replication by divergent virus families, including positive and negative-strand RNA viruses[1].

FGI-106 (0.1-5 mg/kg; intraperitoneal injection; treatments on days 2 and 5; C57BL/6 or BALB/c mice) treatment decreases mortality from Zaire EBOV in a dose-dependent manner[1]. Animal Model: Male or female C57BL/6 or BALB/c mice (6-10 weeks of age) injected with EBOV (Ebola virus)[1]
