Product Introduction

FRAX597 is an effective, ATP-competitive inhibitor of group I PAKs, and for PAK1(IC50=8 nM), PAK2(IC50=13 nM), and PAK3 (IC50=19 nM).
In vitro
In NOD/SCID mice loaded with Nf2-/-SC4 Schwann cells, daily oral administration of FRAX597 (100 mg/kg) significantly inhibits tumor growth. Similarly, in SCID mice with intrinsic meningiomas, daily oral intake of FRAX597 (90 mg/kg) markedly suppresses tumor growth. Additionally, in KrasG12D mice, daily treatment with FRAX597 (90 mg/kg) leads to tumor regression and a decrease in Erk and Akt activity.
In vivo
FRAX597 exhibits potent inhibition against wild-type PAK1 (IC50=48 nM), whereas it shows significantly reduced efficacy against the V342F PAK1 mutation (IC50 > 3 μM) and the V342Y PAK1 mutation (IC50 > 2 μM). At a concentration of 100 nM, FRAX597 demonstrates substantial inhibitory effects on YES1 (87%), RET (82%), CSF1R (91%), TEK (87%), PAK1 (82%), and PAK2 (93%).
Kinase Assay
Determination of Enzyme IC50 Values: IC50 values are determined using a 10 concentration point, non-radioactive, functional assay that employs a fluorescence-based, coupled-enzyme format, according to the manufacturer's protocol (Z'-LYTE@biochemical assay). Kinase selectivity is determined using both the Z'-LYTE@ and Adapta@ kinase assay format.
Cell Research
30,000 cells/well are plated in 12-well dishes in triplicate. Cell growth media with or without FRAX597 is replaced daily. At indicated time points, cells from individual wells are trypsinized and counted using a Coulter counter.(Only for Reference)

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:
For example, your dosage is 10 mg/kg,each TargetMol | Animal experiments animal weighs 20 g, and the dosage volume is 100 μL. A total of TargetMol | Animal experiments 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 μLDMSOTargetMol | 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 μLDMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μLTween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify.
