BMS-986165 是一种高选择性、口服生物可利用的变构 TYK2 抑制剂，用于治疗自身免疫性疾病。它通过稳定调节 JH2 结构域来阻断受体介导的 Tyk2 激活，可抑制IL-12/23和 I 型IFN途径。它选择性结合 TYK2 假激酶 (JH2) 结构域，IC50为1.0 nM。

BMS-986165 inhibits IL-12/23 and type I IFN pathways[1][2]. BMS-986165 is a highly selective, orally bioavailable allosteric TYK2 inhibitor for the treatment of autoimmune diseases. Which selectively binds to TYK2 pseudokinase (JH2) domain (IC50=1.0 nM) and blocks receptor-mediated Tyk2 activation by stabilizing the regulatory JH2 domain.

BMS-986165 maintains excellent potency in human and mouse whole blood (IC50s=13 and 100 nM, respectively). Which shows no significant hERG inhibition in the flux assay (IC50>80 μM).BMS-986165 is differentiated from previous JAK inhibitors due its unique ability to selectively bind to the pseudokinase (JH2) domain of TYK2 and inhibit its function through an allosteric mechanism[1].

BMS-986165 as a high affinity JH2 ligand and potent allosteric inhibitor of TYK2. In addition to unprecedented JAK isoform and kinome selectivity, BMS-986165 shows excellent pharmacokinetic properties with minimal profiling liabilities and is efficacious in several murine models of autoimmune disease. On the basis of these findings, BMS-986165 appears differentiated from all other reported JAK inhibitors and has been advanced as the first pseudokinase-directed therapeutic in clinical development as an oral treatment for autoimmune diseases[1].
