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.

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]


Kinase Assay:[1]
- Collapse

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 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.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
