Product Introduction

Bioactivity
Description
PRN1371 is a specific and potent FGFR1-4 and CSF1R inhibitor (IC50s: 0.6/1.3/4.1/19.3/8.1 nM for FGFR1/2/3/4 and CSF1R).
Targets&IC50
FGFR3:4.1 nM (IC50), CSF1R:8.1 nM (IC50), FGFR4:19.3 nM (IC50), FGFR2:1.3 nM (IC50), FGFR1:0.6 nM (IC50)
In vitro
PRN1371 exhibits high biochemical and cellular potency (FGFR1 IC50: 0.6 nM, SNU16 IC50: 2.6 nM), sustained target engagement (FGFR1 occupancy 24 h = 96%), less than 30% hERG inhibition at 1 μM, and favorable predicted ADME stability with BME reactivity Kd > 100 μM.
In vivo
In PK studies of rat, dog, and cynomolgus monkey, PRN1371show rapid iv clearance in all species. PRN1371 shows rapid clearance (Cl=160 mL per min per kg), yet dosing p.o (20 mg/kg) demonstrates high oral exposure (AUC=4348 h·ng/mL) and a reasonable half-life (t1/2=3.8 h). Low levels of pFGFR2 confirm the ability of PRN1371 to block FGFR2 activity in tumor tissue. PRN1371 induces a dose-dependent reduction in tumor volume and up to 68% tumor growth inhibition at the highest dose of 10 mg/kg b.i.d. following 27 days of treatment. All doses are well tolerated with no significant bodyweight loss.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
