          Description
          OverviewA non-cytotoxic imidazonaphthyridine compound that directly binds interferon-α receptor 2 (IFNAR2) extracelluar domain in a 1:1 ratio and activates cellular signaling via IFNAR2 homodimerization in an IFNAR1-independent manner, eliciting similar, but not identical, signaling events as those seen with IFN--α, IFN--β, or IFN--γ stimulation. While being a much stronger stimulant of STAT3 Y705/S727 & JAK1 Y1022/1023 phosphorylations, RO8191 is ineffective in inducing IFNAR1-dependent Tyk2 Y1054/1055 phosphorylations (10 µM for 15 min; in Huh-7 cultures). Effectively boosts host anti-HCV (EC50 = 200 nM in Huh-7-derived HCV replicon cell line) and anti-EMCV (90% viability with 1.23 µM RO8191 in EMCV-infected A549 cultures) by inducing ISG/IFN-stimulated genes expression both in cultures in vitro and in mice (30 mg/kg p.o.) in vivo.

          DescriptionA non-cytotoxic (up to 10 µM and 7 d in human hepatocyte Huh-7-derived HCV replicon cultures) imidazonaphthyridine compound that directly binds to the extracelluar domain of interferon-α receptor 2 (IFNAR2) in a 1:1 stoichiometric ratio and activates cellular signaling events in a IFNAR2-dependent and IFNAR1-independent manner distinct from that of interferon-α, which stimulates cellular responses only via IFNAR1/2 heterodimerization. Cellular stimulation by RO8191 via IFNAR2 homodimerization elicits similar, but not identical, signaling events as those seen with IFN-α, IFN-β, or IFN-γ stimulation. While being a much stronger stimulator of STAT3 Y705/S727 & JAK1 Y1022/1023 phosphorylations, RO8191 is ineffective in inducing IFNAR1-dependent Tyk2 Y1054/1055 phosphorylations (1 & 10 µM; 15 min; in Huh-7 cultures). Effectively boosts host anti-HCV (EC50 = 200 nM in Huh-7-derived HCV replicon cell line) and anti-EMCV activity (90% vs. <3% viability with or without 1.23 µM RO8191 in EMCV-infected human A549 lung carcinoma cultures) by inducing ISG/IFN-stimulated genes expression both in cultures in vitro and in mice (30 mg/kg p.o.) in vivo and is efficacious in reducing serum HCV titre when administered to HCV-infected mice harboring humanized liver (30 mg/kg p.o.).
