– BMS-986202 (BMS 986202) is potent, selective Tyk2 inhibitor that binds to Tyk2 JH2 domain with IC50 of 0.19 nM, Ki of 0.02 nM, >10,000-fold over 273 kinases and pseudokinases;
BMS-986202 demonstrated cellular activity (IL-23 IC50=12 nM) in IL-23 stimulated reporter assay (in Kit225 T cells).
BMS-986202 also binds Jak1 JH2 with an IC50 of 7.8 nM, but this enzymatic binding did not lead to any functional activities, as BMS-986202 displayed an activity (IC50) of greater than 12.5 ?M in the IL-2 stimulated Jak1/3-dependent cellular assay.
BMS-986202 showed in vivo efficacy in mouse models of IL-23-driven acanthosis, anti-CD40-induced colitis, and spontaneous lupus.
