Oral administration of deltamethrin (5 mg/kg x7 or 15 or 21 days) was found to produce a time-dependent increase in the mRNA expression of xenobiotic metabolizing cytochrome P450 1A1 (CYP1A1), 1A2 and CYP2B1, 2B2 isoenzymes in rat brain.

CYP1A2, CYP1A1, and CYP2C11 in decreasing order of importance quantitatively, metabolized deltamethrin.

At 100 microM deltamethrin 2-3 fold induction of CYP1A1 and CYP2B6 mRNA was observed, while at the same time an approximately 25-fold induction of CYP3A4 was noted.

RT-PCR analysis revealed dose-dependent increase in the mRNA expression of cerebral and hepatic CYP1A1, 1A2, 2B1, 2B2, and 2E1 isoenzymes in the offsprings exposed prenatally to deltamethrin.

The goal of this work was to study the ability of 18 pesticides to inhibit selective model activities for all major xenobiotic-metabolizing enzymes, namely CYP1A1/2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1 and 3A4.
Deltamethrin and fenvalerate were potent inhibitors of CYP2D6 (IC (50) values of approximately 3 micro M) while lambda-cyhalothrin potently inhibited both CYP2D6 and CYP3A4-mediated activities (IC (50)'s about 3-4 micro M).

Rat P450 isoforms CYP1A1, CYP2C6, CYP2C11, and CYP3A2 and human P450 isoforms CYP2C8, CYP2C19, and CYP3A5 were capable of metabolizing either pyrethroid.
