Product formation was NADPH dependent and inhibited by the cytochrome P450 inhibitors, piperonyl butoxide and SKF525.
The metabolism of NPs using microsomes from phenobarbital-treated rats was inhibited by 4-amino-2, 6-dinitro-1-t-butylxylene, a specific CYP2B enzyme inhibitor.

The pre-treatment of PBO greatly decreased mRNA expression and activity of hepatic CYP2B, which metabolizes cyclophosphamide into teratogenic acrolein and cytotoxic phosphoramide mustard.

Pretreatment of male Han Wistar rats with beta-naphthoflavone, phenobarbitone, butylated hydroxytoluene, piperonyl butoxide, Aroclor 1254, or cobalt protoporphyrin IX, agents known to modify hepatic CYP, all afforded some degree of protection against a hepatotoxic dose of methapyrilene (150 mg/kg x 3 days p.o.), as assessed by clinical chemistry and histology.
Protection against hepatic damage was strongly associated with beta-naphthoflavone induction of CYP1A and phenobarbitone-associated CYP2B induction.
