IFN alpha-IFNAR-IN-1 hydrochloride is a nonpeptidic, low-molecular-weight inhibitor of the interaction between IFN-α and IFNAR; inhibit MVA-induced IFN-α responses by BM-pDCs (IC50=2-8 uM).IC50 value:Target: IFN alpha-IFNAR interaction inhibitorIFN alpha-IFNAR-IN-1 specifically inhibits MVA-induced IFN-α responses by BM-pDCs. IFN alpha-IFNAR-IN-1 inhibited the IFN-α responses that were elicited after treatment with CpG2216, stimulation with poly(I:C), and infection with VSV-M2, whereas the total IL-12 production was notably less affected under those conditions. IFN alpha-IFNAR-IN-1 exerts immunosuppressive activity by the direct interaction with IFN-α [1].
