JS25

JS25 is a potent, selective, covalent TEC family of non-receptor tyrosine kinases (BTK, ITK, TXK and BMX) inhibitor with IC50 of 3.5 and 5.8 nM for BMX and BTK, respectively.JS25 displays a strong binding affinity against all the members of TEC family, covalently inhibits BMX at Cys496. JS25 demonstrates intracellular target engagement in HEK293 cells (IC50=44.8 nM), 10 times greater than BMX-IN-1.JS25 inhibits androgen-receptor positive prostate-cancer cells with GI50 of 6.6 uM.JS25 shows synergistic anti-proliferative activity in LNCaP cells in combination with AKT1/2 (AKT inhibitor), Flutamide (androgen receptor antagonist) and LY293002 (PI3K inhibitor).
