The estrogenic mycotoxin zearalenone (ZEN) can undergo hepatic reductive metabolism to form the estrogenic α and β isomers of zearalenol. ZEN also undergoes cytochrome P450 monooxygenase (P450)-mediated oxidative metabolism to form monohydroxylated products, but until now nothing is known about the estrogenic potency of these metabolites. This study aimed at investigating the metabolism of ZEN by different P450 isoforms and to determine the estrogen receptor α (ERα) affinities of the in vitro P450-generated ZEN metabolites in an online high-resolution screening (HRS) setup.
