PG - 120894 LID - S0269-7491(22)02109-1 [pii] LID - 10.1016/j.envpol.2022.120894 [doi] AB - We selected azole pesticides products that are managed by setting maximum residue limits (MRLs) in the Republic of Korea and describe the estrogen receptor (ER) alpha-related negative effect to endocrine system using in vitro Organization for Economic Cooperation and Development performance-based test guideline. No azoles were found to be an ERalpha agonist. Conversely, three azoles (bitertanol, cafenstrole, and tebufenpyrad) were determined to be ERalpha antagonists. In addition, the ERalpha antagonistic activities of bitertanol, cafenstrole, and tebufenpyrad were not significantly perturbed in the existence of phase I (hydroxylation, dealkylation, oxidation or reduction) and phase II (conjugation). Regarding the mechanism underlying their ERalpha-mediated endocrine disrupting potentials, ERalpha proteins cannot be translocated to the nucleus by suppressing the dimerization of ERalpha in the cytoplasm by bitertanol, cafenstrole, and tebufenpyrad. These data indicated that azole pesticide products show the capability to interfere the ERalpha-related human endocrine system. Furthermore, we identified the mechanism of ERalpha-mediated endocrine disrupting by azole insecticide products through this study. CI - Copyright (c) 2022 Elsevier Ltd. All rights reserved.
