FGI-106 tetrahydrochloride demonstrates potent inhibitory activity across a broad spectrum of viruses, including those causing hemorrhagic fevers such as Ebola, Rift Valley, and Dengue Fever, with half-maximal effective concentrations (EC50s) of 100 nM, 800 nM, and 400-900 nM, respectively. Additionally, it effectively inhibits non-hemorrhagic fever viruses, notably HCV and HIV-1, with EC50s of 200 nM and 150 nM, respectively, indicating its broad-spectrum antiviral potential.
