Role of metabolism in drug-induced idiosyncratic hepatotoxicity.

abstract：:Styrene is metabolized to styrene oxide, a direct-acting mutagen and carcinogen. Styrene oxide reacts with DNA mainly at the N-7 position in guanine, but also at other sites and with other bases. Substitution occurs at both the alpha- and beta-positions of the styrene molecule. Experiments with radiolabeled styrene an...
