Branebrutinib

CAS No. : 1912445-55-6

MCE 站：Branebrutinib

产品活性：Branebrutinib (BMS-986195) 是一个强有效的、布鲁顿氏酪氨酸激酶 (BTK) 的不可逆共价、选择抑制剂，其 IC₅₀ 值 0.1 nM。

研究领域：Protein Tyrosine Kinase/RTK

作用靶点：Btk

In Vitro: BMS-986195 is a potent and highly selective inhibitor of BTK, which acts by covalently modifying an active-site cysteine residue. BMS-986195 is more than 5000-fold selective for BTK over all kinases outside of the Tec family, and selectivity ranges from 9- to 1010-fold within the Tec family. BMS-986195 inactivates BTK in human whole blood with a rapid rate of inactivation (3.5×10^-4nM^-1?min^-1) and potently inhibits antigen-dependent interleukin-6 production, CD86 expression and proliferation in B cells (IC₅₀<1 nM) without effect on antigen-independent measures in the same cells. A similar potency is measured against FcγR-dependent TNF-α production in human cells.

In Vivo: In mice, BMS-986195 demonstrates robust efficacy in murine models of RA including CIA and CAIA, protecting against clinically evident disease, histologic joint damage and bone mineral density loss. In both mice and monkeys, maximal efficacy is observed at doses ≤0.5 mg/kg PO QD, which achieves ≥95% inactivation of BTK in vivo. At similar doses, BMS-986195 is also highly protective against nephritis in the NZB/W mouse model of lupus. To investigate the dynamics of BTK inactivation and resynthesis of BTK, cynomolgus monkeys are given single or multiple doses of BMS-986195. 100% peak inactivation of BTK is obtained with a single administration of BMS-986195 at 0.5 mg/kg PO.
