Biological Activity

A potent, specific aryl hydrocarbon receptor (AhR) antagonist that potently inhibits TCDD-induced AhR-dependent transcription with IC50 of 0.03 uM; shows no agonist-like effect, and no activity on estrogen receptor; inhibits TCDD-AhR binding and TCDD-induced nuclear translocation and DNA binding of AhR, blocks TCDD-mediated cytochrome P450 expression (CYP1A1) in HepG2 cells; prevents TCDD-elicited cytochrome P450 induction, liver toxicity, and wasting syndrome in mice.
