Mechanism of Action

Targets/IC₅₀/Ki	FGFR4 ^[1] (Cell-free assay) 3 nM FGFR3 ^[1] (Cell-free assay) 150 nM
In vitro	In MDA-MB-453 cells, BLU9931 potently inhibits phosphorylation of FGFR4 signaling pathway. This compound inhibits proliferation of HCC cell lines that express an intact FGFR4 signaling complex, such as Hep 3B, HUH-7, and JHH-7 cell lines, with EC50 of <1 μM. It also inhibits proliferation in PDX-derived cell lines with an intact FGFR4 signaling pathway. ^[1]
Kinase Assay	FGFR1-4 Biochemical Assays
Kinase Assay	FGFR kinase inhibition assays are performed at KM for ATP. Picomolar to low nanomolar concentrations of FGFR proteins are incubated in 1× Kinase Reaction Buffer (KRB) with 1 μM of CSKtide and 50 to 250 of μM ATP at 25°C for 90 minutes in the presence or absence of a dosed concentration series of this compound. All reactions are terminated by the addition of Stop buffer, and plates are read on a Caliper EZReader2. IC50 values are fit with a four-parameter log[Inhibitor] versus response model with floating Hill Slope.
In vivo	In mice bearing the FGF19-amplified Hep 3B liver tumors, BLU9931 (300 mg/kg, p.o.) leads to tumor regression and prevents this weight loss induced by tumors. In mice bearing the FGF19-overexpressing PDX-derived LIXC012 xenografts, treatment with this compound also leads to tumor regression. ^[1]
