Product Introduction

Bioactivity
Description
ARQ-531 is a potent and orally active BTK inhibitor with potential antineoplastic activity, with IC50s of 0.85 nM and 0.39 nM for WT-BTK and C481S-BTK, respectively.
Targets&IC50
BTK (C481S):0.39 nM, BTK (WT):0.85 nM
In vitro
In vitro treatment of patient CLL cells with ARQ 531 decreases BTK-mediated functions including B-cell receptor (BCR) signaling, viability, migration, CD40 and CD86 expression, and NF-κB gene transcription.?Additionally, ARQ 531 inhibits CLL cell survival and suppresses BCR-mediated activation of C481S BTK and PLCγ2 mutants, which facilitate clinical resistance to ibrutinib[2].
In vivo
In vivo, ARQ 531 was found to increase survival over ibrutinib in a murine Eμ-TCL1 engraftment model of CLL and a murine Eμ-MYC/TCL1 engraftment model resembling Richter transformation[2].

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.
