Pretreatment of mice with the P450 inducer phenobarbital enhanced the hepatotoxic response, as indicated by an increase in plasma alanine aminotransferase (ALT) levels and hepatic necrosis, while pretreatment with the P450 inhibitor piperonyl butoxide markedly attenuated the toxic response.

Plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities were markedly elevated 24 hr after subcutaneous administration of DDC and histologically, the liver showed submassive necrosis.
Desferrioxamine (a chelator of iron) and piperonyl butoxide (an inhibitor of cytochrome P-450) prevented DDC-induced increases of both ALT and TBARS, but GSH did not, DDC hepatotoxicity was not changed by phenobarbital induction.

Plasma alanine aminotransferase (EC 2.6.1.2) activity was also elevated.
Although, in further studies, total microsomal cytochrome P-450 content and ethoxyphenoxazone de-ethylase activity reached a peak a few days after dosing and had declined significantly at the time of maximum inhibition of the decarboxylase, additional treatment of HCB-dosed mice with a cytochrome P1-450 inducer, beta-naphthoflavone, enhanced the inhibition, whereas piperonyl butoxide, an inhibitor of cytochrome P-450, partially protected.

Massive hepatotoxicity accompanied by an increase in serum glutamate pyruvate transaminase (SGPT) and a decrease in glucose-6-phosphatase were observed upon treatment with pulegone.
Pretreatment of rats with phenobarbital (PB) or diethylmaleate (DEM) potentiated the hepatotoxicity caused by pulegone, whereas, pretreatment with 3-methylcholanthrene (3-MC) or piperonyl butoxide protected from it.

The severity of the lesions was dose-dependent up to 200 mg/kg and also manifest by an increase in serum alanine aminotransferase and aspartate aminotransferase activities.
Pretreatment with SKF-525A resulted in increased hepatic injury, while pretreatment with piperonyl butoxide, cimetidine, or 3-methylcholanthrene had no effect on hepatic damage by loxistatin.

Treatment with inhibitors of hepatic cytochrome P-450-dependent monooxygenases, carbon disulfide, metyrapone and piperonyl butoxide also prevented the hepatotoxicity.
