Compared to control incubations (no inhibitor) where cholinesterase activity was inhibited to between 1 and 4% of control levels, incorporation of the CYP2D6 inhibitor quinidine into the microsomal incubation resulted in cholinesterase activity of 50% for parathion, 38% for diazinon and 30% for chlorpyrifos.

Microsomes containing human CPR and CYP2D6 converted different substrates, such as 3-cyano-7-ethoxycoumarin, parathion and dextrometorphan.

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.
