The goals of this study were to examine effects of propiconazole, triadimefon, and myclobutanil, three triazole-containing conazoles, on the microsomal metabolism of atRA, the associated hepatic cytochrome P450 (P450) enzyme (s) involved in atRA metabolism, and their effects on hepatic atRA levels in vivo.

Three agricultural antifungal triazoles that are known to modulate expression of cytochrome P450 (CYP) genes and enzymatic activities were tested for effects on steroidogenesis using rat in vivo (triadimefon), rat in vitro (myclobutanil and triadimefon), and human in vitro (myclobutanil, propiconazole, and triadimefon) model systems.

Toxicol Pathol. 2006;34(7):853-62.

As a component of a large-scale study aimed at determining the mode (s) of action for tumorigenic conazoles, we report the results from comparative evaluations of liver and body weights, liver histopathology, cell proliferation, cytochrome P450 (CYP) activity, and serum cholesterol, high-density lipoprotein and triglyceride levels after exposure to propiconazole, triadimefon, and myclobutanil.

ABSTRACT We identified the cytochrome P450 sterol 14alpha-demethylase (CYP51A1) gene from Venturia inaequalis and optional insertions located upstream from CYP51A1 and evaluated their potential role in conferring resistance to the sterol demethylation-inhibitor (DMI) fungicide my-clobutanil.

Toxicol Appl Pharmacol. 2006 Sep 15;215(3):260-73. Epub 2006 Apr 27.

Adult male Sprague-Dawley rats were dosed for 14 days by gavage with fluconazole, myclobutanil, propiconazole, or triadimefon.
Triazole fungicides are designed to inhibit fungal cytochrome P450 (CYP) 51 enzyme but can also modulate the expression and function of mammalian CYP genes and enzymes.

Toxicol Appl Pharmacol. 2006 Sep 15;215(3):274-84. Epub 2006 May 26.

Besides organ weight, histopathology, and cytochrome P450 (CYP) enzyme induction, DNA microarrays were used to generate gene expression profiles and hypotheses on potential mechanisms of action for this class of chemicals.
Adult male CD-1 mice were exposed daily for 14 days to fluconazole, myclobutanil, propiconazole, or triadimefon at three dose levels by oral gavage.
