Brief Description

CH-223191 is a ligand-selective antagonist of the Ah (Dioxin) receptor.
Target: AhR antagonist
in vitro: CH-223191 preferentially inhibits the ability of some classes of AhR agonists (2,3,7,8-tetrachlorodibenzo-p-dioxin and related HAHs), but not others (PAHs, flavonoids, or indirubin), to bind to and/or activate the AhR and AhR signal transduction [1]. CH-223191 potently inhibits TCDD-induced AhR-dependent transcription. In addition, CH-223191 blocked the binding of TCDD to AhR and inhibited TCDD-mediated nuclear translocation and DNA binding of AhR [2].
