AhR Antagonist
CH-223191 is a synthetic antagonist for the cytosolic aryl hydrocarborn receptor (AhR) transcription factor [1].
It exerts a ligand-selective antagonism and appears to be more effective on halogenated aromatic hydrocarbons such as the xenobiotic 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), than on polycyclic aromatic hydrocarbons and non halogenated aromatic hydrocarbons such as FICZ and ITE, respectively [2].
InvivoGen's CH-223191 is of high quality, guaranteed free of bacterial contamination, and has been functionally tested on HepG2-Lucia™ AhR and HT29-Lucia™ AhR reporter cells.
