The present study was performed to investigate the subacute effect of alpha-cypermethrin (alpha-CP) in rats.
Activities of various enzymes, cytochrome P450 and b5 contents in liver, hepatic antioxidant status, tissue residue concentration, haemogram and pathological changes were studied.

Comparison of the expression levels induced by eight plant allelochemicals, one drug (phenobarbital), and an insecticide (alpha-cypermethrin) indicates that, for the most part, the four P450s respond individually to these inducers, with all four induced strongly by chlorogenic acid, a shikimate pathway intermediate and a lignin biosynthesis intermediate present in a wide variety of plants, and indole-3-carbinol, a glucobrassicin breakdown product present in the Brassicaceae.

In the corn earworm Helicoverpa zea, a noctuid of considerable economic importance, metabolisms of xanthotoxin, a toxic furanocoumarin, and alpha-cypermethrin, an insecticide, are mediated by at least one P450 with a catalytic site capable of accepting both substrates.

Cytochrome P450 monoxygenase activities showed an association with resistance.

Xanthotoxin, a plant allelochemical, induces alpha-cypermethrin insecticide tolerance in Helicoverpa zea (corn earworm); inhibition of tolerance by piperonyl butoxide implicates cytochrome P450 monooxygenases (P450s) in the detoxification of this insecticide.

With the exceptions of alpha-cypermethrin, cypermethrin, isoproturon, carbaryl and abamectin, most pesticides inhibited relatively potently at least one CYP-selective activity, which may have relevance for potential interactions in occupational exposures and for further studies on the CYP-associated metabolism of respective pesticides.
