| Description | Erdafitinib (JNJ-42756493), a quinoxaline derivative, targets FGFR1/2/3/4. |
| Targets & IC50 | FGFR2:2.5nM, FGFR3:3.0nM, FGFR4:5.7 nM, FGFR1:1.2 nM |
| 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]. |

| Cell Research | 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. (Only for Reference) |

| Solubility Information | Ethanol: 15 mg/mL (33.59 mM), Sonication is recommended. H2O: < 1 mg/mL (insoluble or slightly soluble) DMSO: 32 mg/mL (71.66 mM), Sonication is recommended.  | |||||||||||||||||||||||||||||||||||
| In Vivo Formulation | 10% DMSO+40% PEG300+5% Tween 80+45% Saline: 8.2 mg/mL (18.36 mM), Solution. Please add the solvents sequentially, clarifying the solution as much as possible before adding the next one. Dissolve by heating and/or sonication if necessary. Working solution is recommended to be prepared and used immediately. The formulation provided above is for reference purposes only.

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
