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).

We therefore tested the comparative acute and chronic toxicity of chemicals belonging to the major insecticides families (DDT, malathion and tetrachlorvinphos, carbaryl, cypermethrin, diflubenzuron), in hepatocytes, HepG2 and HaCaT cell lines.
Two kinds of end-points were used: cytotoxicity parameters and CYP1A1 induction.
