Product Introduction

Bioactivity
Description
XL228 is an inhibitor of multi-targeted tyrosine kinase (IC50s: 5, 3.1, 1.6, 6.1, 2 nM for Bcr-Abl, Aurora A, IGF-1R, Src, and Lyn, respectively).
Targets&IC50
Aurora A:3.1 nM, IGF-1R:1.6 nM
In vitro
XL228 inhibits phosphorylation of BCR-ABL and its substrate STAT5 in K562 cells in vitro (IC50s: 33 and 43 nM, respectively). XL228 eliminates the phosphorylation of Aurora A and B at concentrations above 10 nM. XL228 displays a broad pattern of protein kinase inhibition, including the tyrosine kinases IGF1R, SRC, ABL, FGFR1-3, and ALK and the serine/threonine kinases Aurora A and Aurora B. Approximately 30% of the lines demonstrate XL228 IC50 values of <100nM in viability assays, including many lines with characterized ALK or FGFR mutations or amplifications [2][3].
In vivo
Single-dose pharmacodynamics studies demonstrate that XL228 on BCR-ABL signaling in K562 xenograft tumors has a potent effect. At XL228 plasma concentrations of 3.5 μM, phosphorylation of BCR-ABL is decreased by 50%; a similar decrease in phospho-STAT5 occurred at 0.8 μM plasma concentration [3].

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.
