Eugenol produces hepatic injury in mice depleted of glutathione (GSH) by pretreatment with buthionine sulfoximine (BSO). Several eugenol analogs were examined for their ability to cause hepatic injury after administration to mice in combination with BSO. Hepatotoxicity was assessed by measuring relative liver weight, liver blood volume, and serum GPT activity in mice. Comparison of the treated compounds showed that the structural requirements for toxic potency was a phenolic ring having an allyl substituent at the 4-position. These structural requirements can be explained by assuming that a vinylogous quinone methide formed by metabolic oxidation of eugenol plays a role in inducing hepatotoxicity in GSH-depleted mice.
