In vitro

JNJ-42756493 is a potent, oral pan-FGFR tyrosine kinase inhibitor with half-maximal inhibitory concentration values in the low nanomolar range for all members of the FGFR family (FGFR1 to FGFR4), with minimal activity on vascular endothelial growth factor receptor (VEGFR) kinases compared with FGFR kinases (approximately 20-fold potency difference). In vitro, the proliferation of cells treated with JNJ-42756493 is decreased, associated with increased apoptotic death and decreased cell survival[2].

In vivo

In vivo, growth of NCI-H716 tumors is delayed by 5 days by drug treatment alone, although when drug delivery is stopped the relative tumor volume increased compared to control[2]. JNJ-42756493 shows favorable drug like properties and displays a high distribution to lung, liver and kidney tissue. JNJ-42756493 is well tolerated at efficacious doses and results in potent dose-dependent antitumor activity accompanied by pharmacodynamic modulation of tumor FGFR and downstream pathway components[1].

Protocol (from reference)

Cell Research:


  • Cell lines: HCT116, HCA7, Caco2 and NCI-H716 cells
  • Concentrations: --
  • Incubation Time: 72 h
  • Method:

    The effect of varying drug concentrations on cell growth and survival is evaluated at 72 h using sulforhodamine B (SRB) assay for the adherent cells (HCT116, HCA7, Caco2) and trypan blue dye exclusion for the suspension cells, NCI-H716.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
