An FGFR4 inhibitor (IC50 = 50s = 320, 1,290, and 1,060 nM, respectively), as well as TAOK2, JNK2, and CSF1R (IC50s = 690, >10,000, and >10,000 nM, respectively); decreases cell growth (GI50 = 25 nM) and increases caspase-3/7 activity in Hep3B HCC cells; selectively inhibits cell growth in HCC cell lines that express high levels of FGF19; reduces tumor growth in a Hep3B HCC mouse xenograft model at 100 and 300 mg/kg
