Description
A multi-kinase inhibitor; inhibits BTK, LCK, and LYN (Kis = 8.2, 4.6, and 2.5 nM, respectively), as well as the activity of three receptor tyrosine kinases and seven non-receptor tyrosine kinases by greater than 90% in a panel of over 100 kinases at 10 µM; inhibits calcium flux in Ramos B cells and phosphorylation of PLCɣ1 (IC50s = 0.53 and 0.33 µM, respectively); cytotoxic to S1-MI-80, H460/MX20, and KBv200 cancer cells overexpressing the ATP-binding cassette transporter (IC50s = 7.8, 6.3, and 6.02 µM, respectively); in combination with topotecan, reduces tumor growth in an H460/MX20 mouse xenograft model at 20 mg/kg
