A hit compound that inhibits the proliferation of human peripheral blood T cells stimulated with anti-CD3 with IC50 of <10 nM, inhibits TCR-Nck interaction..

AX-024 is an cytokine release inhibitor which can strongly inhibit the production of interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), interferon-γ (IFN-γ), IL-10 and IL-17A.

AX-024 is the first-in-class inhibitor of T cell receptor (TCR); AX-024 is an orally available inhibitor of the TCR-Nck interaction that selectively inhibits TCR-triggered T cell activation (IC50 value 1 nM).
