Pathway for the conversion of IQ to an aryl nitrenium ion, via N-Hydroxy-IQ (box), and the chemical structures of various compounds in tea. Note: formation of the aryl nitrenium ion from N-Hydroxy-IQ occurs spontaneously, but is facilitated by various enzymes, including bacterial O-acetyltransferase (OAT). Sites labeled i–iii are potential targets for inhibition by antimutagens (see text).
