A cell-permeable pyrimidinylphenylamine compound that directly and reversibly targets aryl hydrocarbon receptor (AhR) with high-affinity, and induces AhR signaling. Reported to act as an immunomodulator with anti-inflammatory properties. Potently suppresses IgE secretion in B-cells with an IC50 of ~2nM, and inhibits dendritic cells-mediated T-cell proliferation and cytokine production. Further, decreases lung eosinophilia in B-cell-deficient mice, and allergic inflammation. Downregulates PU.1 transcription factor, and impairs human monocytes and Langerhans dendritic cells differentiation.
