Interferon-α-IFNα-R Interaction Inhibitor

A nonpeptidic thiophenylmethanamine compound that binds interferon-α (K_d = 4 µM for human IFN-α) and prevents IFN-α and IFNAR interaction-dependent IFN-α production in murine BM-pDCs (bone marrow-derived plasmacytoid dendritic cells) cultures upon MVA (vaccinia virus Ankara) infection (IC₅₀<4.5 µM), TLR9 ligand CpG2216 stimulation, VSV-M2 (vesicular stomatitis virus variant 2) infection, or MDA5/TLR3 ligand poly(I:C) stimulation (by >95% inhibition at 9 µM), while exhibiting no inhibitory effect against IL-12 production in the same cultures when applied at non-toxic concentrations (≤4.5 µM).
