1,3-DICHLORO-5-[(1E)-2(4-TRIFLUOROMETHYLPHENYL)ETHENYL]-BENZENE

The aryl hydrocarbon receptor (AhR) is a ligand-dependent intracellular transcription factor whose ligands include some of the most infamous xenobiotics, including dioxin, benzo[a]pyrene, and numerous polyaromatics from soot and coal tar. CAY10465 is an analog of resveratrol acting as a potent and selective AhR agonist, with a K_i of 0.2 nM. CAY10465 is inactive as a ligand for the estrogen receptor even at 100 μM.

(E)-1-[4-(Trifluoromethyl)phenyl]-2-(3,5-dichlorophenyl)ethene is a stilbene derivative of resveratrol and a selective aryl hydrocarbon receptor agonist.
