SynonymsN-(2-Methyl-5-(9-(4-(methylsulfonamido)phenyl)-2-oxobenzo[h][1,6]naphthyridin-1(2H)-yl)phenyl)acrylamide, BMX/BTK Inhibitor, Bruton's Tyrosine Kinase Inhibitor IV, BLK Inhibitor I, BMX Inhibitor I, JAK3 Inhibitor XIII, PI 3-K Inhibitor XX, PIP5K2C Inhibitor I, SBK1 Inhibitor I, TEC Inhibitor I, TXK Inhibitor I
DescriptionA cell-permeable tricyclic quinoline-acrylamide compound that potently inhibits BMX and BTK kinase activity (IC50 = 8 and 10.4 nM, respectively) by covalently targeting ATP-binding site cysteine (Ser496 and S481 of respective human sequence), while being less potent against 3 other TEC family kinases with the same conserved cysteine (IC50 = 175, 377, and 653 nM against TEC, JAK3, and BLK, respectively) and completely ineffective toward BMX C496S even at concentrations as high as 10 µM. Only PI 3-Kγ/PIK3CG, SBK1, and PIP5K2C are significantly inhibited by BMX-IN-1 (by ≥94% at 1 µM) in a selectivity profiling against 437 other kinase constructs, including TEC family members EGFR/T790M, ITK (IC50 = 4.28 and 5.25 µM, respectively), TXK, ErbB2/Her2, ErbB4/Her4, JAK1, and JAK2 (75%, 10%, 22%, 13%, and 14% inhibition at 1 µM, respectively). Potently inhibits the proliferation of TEL-BMX transformed Ba/F3 Ba/F3 (GI50 = 25 nM), while being much less effective against TEL-BLK, TEL-JAK1, TEL-JAK2, TEL-JAK3, or TEL-TYK2E957D transformed Ba/F3 (GI50 = 3.64, 4.92, 5.83, 7.98, and 6.09 µM, respectively) or prostate cancer cells using a panel of 5 established lines (GI50 ≥2.46 µM).
