For example, one or more PM have been identified in human CYP1A1, CYP1B1, CYP2C9, CYP2C18, CYP2D6, and CYP2E1.
Recent studies using cDNA expressed human CYPs have suggested that CYP3A4 is the principal human CYP involved in the oxidation of parathion and probably other organo (thio) phosphate (OP) insecticides and thus PM in this CYP might influence susceptibility to OP.

Three monooxygenase activities, namely, lauric acid (omega-1)-hydroxylase (LA-OH), 7,12-dimethylbenz [a] anthracene hydroxylase (DMBA-OH), and progesterone 6beta-hydroxylase (PROG-OH) activities were used as functional markers for trout hepatic CYP2K1, CYP1A1, and CYP3A27, respectively.
These imidazole compounds, as well as ellipticine, parathion, and alpha-naphthoflavone, were the strongest inhibitors of DMBA-OH and PROG-OH activities.
