Generally organophosphorus insecticides were the most potent and extensive inhibitors, especially towards CYP1A1/2 (IC (50) values of chlorpyrifos, fenitrothion and profenofos approximately 3 micro M), CYP2B6 (IC (50) values of chlorpyrifos and fenitrothion 2.5 micro M), CYP2C8 (fenitrothion 4.3 micro M), CYP2C9 (fenitrothion and malathion 4.8 and 2.5 micro M, respectively), CYP2D6 (chlorpyrifos and phenthoate approximately 3 micro M) and CYP3A4 (chlorpyrifos, fenitrothion and phenthoate 3-4 micro M).

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.
