Storage & Solubility Information
Description Infigratinib phosphate (BGJ-398 phosphate) is an effective inhibitor of the FGFR family (IC50: 0.9 nM, 1.4 nM, 1 nM, and 60 nM for FGFR1, FGFR2, FGFR3, and FGFR4, respectively).
Targets&IC50 FGFR4:60 nM, FGFR3:1 nM, FGFR1:0.9 nM, FGFR2:1.4 nM
In vitro Infigratinib inhibits the proliferation of the FGFR1-, FGFR2-, and FGFR3-dependent BaF3 cells with IC50 values which are in the low nanomolar range and comparable to those observed for the inhibition of the receptors kinase activity in the enzymatic assay. Infigratinib phosphate suppresses FGFR1, FGFR2, and FGFR3(IC50=~1 nM), FGFR3K650E(IC50=4.9 nM), and FGFR4(IC50=60 nM). IC50 values for all other kinases are in the μM range (FYN, LCK, YES, and ABL, IC50=1.9, 2.5, 1.1, and 2.3 μM, respectively) except for VEGFR2, KIT, and LYN, which are inhibited at submicromolar concentrations (IC50=0.18, 0.75, and 0.3 μM, respectively). Infigratinib (ranging between 1 nM and 10 μM) is effective at inhibiting cell growth of FGFR2-mutant endometrial cancer cells. For the remaining cells, all IC50 values are greater than 1.5 μM except for VEGFR2 (IC50 1449 and 938 nM), for which there is at least a 400-fold selectivity versus FGFR1, FGFR2, and FGFR3[1][2].
In vivo Infigratinib (30 mg/kg) significantly suppresses the growth of FGFR2-mutated endometrial cancer xenograft models. Infigratinib is administered to athymic nude mice implanted subcutaneously with RT112/luc1 tumors: either as a 5 mg/kg intravenous bolus in NMP/PEG200 (1:9, v/v) or orally by gavage as a suspension in PEG300/D5W (2:1, v/v) at a 20 mg/kg dose. Infigratinib shows a rapid distribution from the vascular compartment into the peripheral tissues after intravenous dosing, translating into a high volume of distribution (26 L/kg). The relevant pharmacokinetic (PK) parameters indicate that the oral bioavailability of Infigratinib in this study is 32%. The plasma clearance is high at 3.3 L/h/kg (61% of liver blood flow). The ratio of tumor to plasma after oral dosing based on AUC is determined to be 10 [1][2].

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
