Information BMS-986142 BMS-986142 is a potent and highly selective reversible small molecule inhibitor of BTK with an IC50 of 0.5 nM. In a panel of 384 kinases, only five kinases were inhibited by BMS-986142 with less than 100-fold selectivity for BTK (TEC, ITK, BLK, TXK and BMX). Targets BTK (Cell-free assay) 0.5 nM In vitro In B cells stimulated through the B cell receptor (BCR), BMS-986142 potently inhibits signaling and functional end points, including calcium flux (IC50 = 9 nM), production of cytokines, proliferation, and surface expression of the costimulatory molecule CD86 (IC50 = 3−4 nM). In T cells, ITK-catalyzed phosphorylation of PLCγ1 stimulated through the T cell receptor (TCR) is at least 45-fold less potently inhibited by BMS-986142 than BTK-dependent signaling end points in B cells, as expected based on the 30-fold selectivity for BTK over ITK in the enzymatic assays. In vivo In multispecies pharmacokinetic studies, the absolute oral bioavailability of BMS-986142 is 93% in mice, 67% in rats, 33% in cynomolgus monkeys, and 100% in dogs. The total body plasma clearance of BMS-986142 is low in all species. The large steady-state volume of distribution observed is indicative of extravascular distribution, in spite of the high protein binding. However, brain penetration is very low in rats ( Cell Research(from reference) Cell lines：Ramos B cells Concentrations：0.4, 1.6, 6, 25, 100 and 400 nM Incubation Time：1 h
