生物活性:
CH-223191 is a potent and specific antagonist of aryl hydrocarbon receptor (AhR).CH-223191 inhibits TCDD-mediated nuclear translocation and DNA binding of AhR, and inhibits TCDD-induced luciferase activity with an IC50 of 0.03 μM.

体内研究:
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.Animal Model:Male ICR mice (6 weeks old)
Dosage:10 mg/kg
Administration:10 mg/kg; once a day; 25 days
Result:Prevented TCDD-elicited cytochrome P450 induction, liver toxicity, and wasting syndrome in mice.

体外研究:
CH-223191 (0.1-10 μM; pre-treated 1 hour)inhibits TCDD-causedcytochrome P450 1A1 mRNA expression in a in dose-dependent manner.CH-223191 (0.1-10 μM; pre-treated 1 hour) causes a concentration-dependent inhibition of TCDD-induced cytochrome P450 enzyme activity.
