Decernotinib (VX-509) is a potent JAK3 inhibitor, with Kis of 2.5, 11, 13 and 11 nM for JAK3, JAK1, JAK2, and TYK2, respectively. Decernotinib potently blocks T-cell proliferation with a mean IC50 of 170 ± 101 nM, and inhibits IL-2-stimulated T-cell proliferation (IC50, 140 and 400 nM). VX-509 is also cytotoxic to B-cell in response to CD40L and IL-4 (IC50, 50 nM).
