RO8191 (CDM-3008) exerts antiviral activity dependent on IFNAR2/JAK1, but is independent of IFNAR1/Tyk2. RO8191, an IFNAR2 agonist, stimulates IFN signals in mice.
RO8191 (0.08, 0.4, 2, 10 μM; for 72 h) strongly suppresses HCV replicon activity at 72 h in a dose-dependent manner. RO8191 reduces levels of the proteins HCV NS3 and NS4A, which are localized mainly in the perinuclear region of the replicon cells.
RO8191 (0.08-10 μM; for 72 h) results in the disappearance of viral proteins such as NS3, NS4A/B, and NS5A/B.
