Sample solution is provided at 25 µL, 10mM.
CH 223191 is an effective and specific antagonist of the aryl hydrocarbon receptor (AhR), capable of inhibiting TCDD-mediated AhR nuclear translocation and DNA binding, and suppresses TCDD-induced luciferase activity, with an IC50 of 0.03 μM[1]. CH-223191 effectively prevents TCDD-induced cytochrome P450 induction, hepatotoxicity, and wasting syndrome in mice.
In vitro, CH 223191 (0.1-10 μM; pre-treated for 1 hour) inhibits TCDD-induced cytochrome P450 1A1 mRNA expression in a dose-dependent manner[1]. CH 223191 reduces the invasiveness of the LNT-229 cell line by 81% and the LN-308 cell line by 72%[2]. Pre-treatment with CH 223191 (10–6 M) significantly reverses the inhibition effect of TCDD (10–9 M) on human AChE promoter activity[3].
In vivo, CH 223191 (10 mg/kg; once daily; for 25 days) inhibits the expression of cytochrome P450 1A1 in the liver of mice treated with TCDD and reduces hepatic fat content, lowering AST and ALT activity[1].

Cell experiment [1]: |
|
Cell lines |
HepG2 cell lines |
Preparation method |
The cells were treated with different concentrations of CH223191 for 5 h. |
Reaction Conditions |
0.1-10 μM; 5 h |
Applications |
CH223191 was able to inhibit the catalytic activity of CYP1A1 with IC50 of 1.48 μM. CYP1A1 transcription activity caused by the CH223191 up to 16.84%. |
Animal experiment [2]: |
|
Animal models |
Male ICR mice |
Preparation method |
Male ICR mice (6 weeks old) were given oral vehicle (corn oil) or CH-223191 (10 mg/kg in corn oil) once a day for 25 days and treated i.p. with TCDD (100g/kg in corn oil) once after the first week of CH-223191 treatment. The body weights of all mice were measured before dosing and at termination. |
Dosage form |
10 mg/kg; 25 days ; oral |
Applications |
CH-223191 (10 mg/kg; once a day; 25 days) suppresses cytochrome P450 1A1 expression and the intrahepatocyte fat content in liver, reduces activity of AST and ALT in TCDD-treated mice. |
