Biological Activity

Description CH-223191 is a potent and specific aryl hydrocarbon receptor (AhR) antagonist with IC50 of 30 nM.
AhR [1]
(in HepG2 cells)
30 nM
In vitro

CH-223191 blocks TCDD-mediated nuclear translocation and DNA binding of AhR, and also causes the inhibition of TCDD-induced cytochrome P450 enzyme activity. [1] In human glioblastoma cells, CH-223191downregulates the TGF-beta/Smad pathway, and reduces clonogenic survival and invasiveness. [2] In SK-N-SH human-derived neuronal cells, CH223191 counteracts the TCDD-induced suppression of neuronal acetylcholinesterase expression. [3] In endothelial cells, CH-223191 potentiates ICAM-1 expression and prevents RelB nuclear translocation. [4]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
