In the current study, we examined the effects of two EBIFs in clinical use, clotrimazole and ketoconazole, and two agricultural EBIFs, propiconazole and vinclozolin, on hepatic monooxygenase activities and P450 apoprotein expression in the male Sprague-Dawley rat and the male bobwhite quail.

Quail kidney microsomes also expressed high levels of a CYP 4A1 cross-reactive apoprotein which was inducible 3-4-fold by ketoconazole.
The effects of treatment with the fungicides: propiconazole, vinclozolin, clotrimazole and ketoconazole were examined.

Azole antifungals (e.g. the imidazoles: miconazole, clotrimazole, bifonazole, imazalil, ketoconazole, and the triazoles: diniconazole, triadimenol, propiconazole, fluconazole and itraconazole) inhibit in fungal cells the 14 alpha-demethylation of lanosterol or 24-methylenedihydrolanosterol.
The consequent inhibition of ergosterol synthesis originates from binding of the unsubstituted nitrogen (N-3 or N-4) of their imidazole or triazole moiety to the heme iron and from binding of their N-1 substituent to the apoprotein of a cytochrome P-450 (P-450 (14) DM) of the endoplasmic reticulum.
