nitro-IQ. This speaks for the formation of a common DNA-reactive species, presumably an arylnitrenium ion, generated by different pathways in these cellular model systems. The similarity of critical biochemical DNA lesions suggests that PHS can contribute to the bioactivation of IQ in vivo: this is of particular interest in extrahepatic tissues since expression of cytochrome P450 isoenzymes known to be
