Among the Friedel-Crafts reaction substrate of aromatic compounds, indoles and indole derivatives have received more and more attention [2] because of their privileged structure and quite pervasiveness in nature [3] as well as their excellent biological activities [4].

As already mentioned, a number of studies have highlighted the capacity of AhR to respond to indolyl metabolites, including indoxyl-3-sulfate, 6-formylindolo[3,2b]carbazole, kyneurenine, kynurenic acid, tryptamine, indole-3-acetate, and dietary indoles (indole-3-carbinol and 3,3'-diindolylmethane from the Cruciferous vegetables), thus positioning the AhR as a candidate indole receptor [11, 15, 43, 44].
