Solubility (25°C)* In vitro DMSO 67 mg/mL (200.96 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.85mg/ml Taking the 1 mL working solution as an example, add 50 μL of 17 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description CH-223191 is a potent and specific aryl hydrocarbon receptor (AhR) antagonist with IC50 of 30 nM.
Targets
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]
In vivo

CH-223191 (10 mg/kg/day, p.o.) potently prevents TCDD-caused cytochrome P450 induction, liver toxicity, and wasting syndrome in mice. [1]

Protocol (from reference)

Kinase Assay:

[1]
  • Luciferase Reporter Gene Assay

    The cells are lysed with lysis buffer (20 mM Tris-HCl, pH 7.8, 1% Triton X-100, 150 mM NaCl, and 2 mM dithiothreitol). The cell lysate is mixed with luciferase activity assay reagent and luminescence produced for 5 s is measured using a luminometer.

Cell Assay:

[1]
  • Cell lines

    HepG2 cells

  • Concentrations

    30 nM

  • Incubation Time

    1 h

  • Method

    HepG2 cells were treated with the various concentrations of CH-223191 or flavone for 1 h and then with 3 nM TCDD for 24 h, and then luciferase activity was assayed.
Animal Study:

[1]
  • Animal Models

    Male ICR mice

  • Dosages

    10 mg/kg/day

  • Administration

    p.o.
