Fenarimol, tebuconazole, and hexaconazole decreased aromatase activity close to cytotoxic concentrations.

Estrogen-like effects on MCF-7 cell proliferation and effects on CYP19 aromatase activity in human placental microsomes were also investigated.
Pesticides (endosulfan, methiocarb, methomyl, pirimicarb, propamocarb, deltamethrin, fenpropathrin, dimethoate, chlorpyriphos, dichlorvos, tolchlofos-methyl, vinclozolin, iprodion, fenarimol, prochloraz, fosetyl-aluminum, chlorothalonil, daminozid, paclobutrazol, chlormequat chlorid, and ethephon) were selected according to their frequent use in Danish greenhouses.

Four pesticides inhibited aromatase activity after 2 h of exposure: prochloraz (IC (50)<1 microM), fenbuconazole (IC (50)=1.1 microM), propiconazole (IC (50)=1.5 microM) and fenarimol (IC (50)=3.3 microM).
To further investigate the mechanisms of aromatase induction we measured CYP19 mRNA expression and showed that methoxychlor, aldrin, chlordane and tributyltin induced the transcription of the cyp19 gene.

Toxicol Sci. 2005 Aug;86(2):300-8. Epub 2005 May 18.

The two fungicides inhibited in vitro CYP19 aromatase activity in brain and ovarian homogenates from the fish, with prochloraz exhibiting a greater potency than fenarimol.

Prochloraz, imazalil, propioconazole, fenarimol, triadimenol, triadimefon (all fungicides), and dicofol (an acaricide) gave rise to a statistically significant inhibition of aromatase activity.
