2'-Deoxy-2'-fluorocytidine, an nucleoside analog, is a potent inhibitor of Crimean-Congo hemorrhagic fever virus (CCHFV) replication. 2′-deoxy-2′-fluorocytidine can act synergistically with T705 to increase the potency of both compounds antiviral effects on CCHFV replication[1].
2'-Deoxy-2'-fluorocytidine has antiviral activities, showing 50% effective concentrations (EC50) of 61 nM and 31 nM against CCHFV and CCHFV/ZsG in Huh7 cells, respectively. And it shows a 50% cytotoxicity concentration (CC50) of >50.0 μM in Huh7 cells[1].
