Biological Activity

Description BLU9931 is a potent, selective, and irreversible FGFR4 inhibitor with IC50 of 3 nM, about 297-, 184-, and 50-fold selectivity over FGFR1/2/3, respectively.
Targets
FGFR4 [1]
(Cell-free assay)		 FGFR3 [1]
(Cell-free assay)
3 nM 150 nM
In vitro In MDA-MB-453 cells, BLU9931 potently inhibits phosphorylation of FGFR4 signaling pathway. BLU9931 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. BLU9931 also inhibits proliferation in PDX-derived cell lines with an intact FGFR4 signaling pathway. [1]
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 BLU9931 (300 mg/kg, p.o.) also leads to tumor regression. [1]

Protocol (from reference)

Kinase Assay:[1]
  • FGFR1-4 Biochemical Assays

    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 inhibitor. 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.
Cell Assay:[1]
  • Cell lines

    Hep 3B, HUH-7, JHH-7, PLC/PRF/5, SK-HEP-1, SNU-182, SNU-387, SNU-398, SNU-423, SNU-449, SNU-878 cells

  • Concentrations

    ~10 μM

  • Incubation Time

    72-120 hours

  • Method

    Established and PDX-derived HCC cell lines are seeded in 96-well plates in respective growth media, allowed to attach overnight, and treated with a dilution series of test compounds for two cell-doubling times. Cell viability is determined by CellTiter-Glo, and results represented as background-subtracted relative light units normalized to a DMSO-treated control. Relative EC50 values are determined at 50% inhibition between the top and bottom plateau of the dose–response curve.
Animal Study:[1]
  • Animal Models

    Mice bearing LIXC012 tumors

  • Dosages

    ~300 mg/kg

  • Administration

    p.o.
