英文摘要Wastewater reclamation and reuse is considered an attractive and practical method for coping with water scarcity. However, the presence of micropollutants in reclaimed water, including endocrine disrupting chemicals (EDCs), is a major public health concern. This study attempted to identify unknown EDCs with liver X receptor (LXR alpha) agonist/antagonist activities in reclaimed wastewater, using nuclear receptors binding extraction coupled with high-resolution mass spectrometry (NRBE-HRMS). In total, 105 compounds in the reclaimed wastewater exhibited LXR alpha-binding activity. Among them, two previously unknown LXR alpha-antagonist compounds, catechol and 4-acetamidoantipyrine, were identified, based on authentic standards. The two LXR alpha-antagonist compounds exhibited weak LXR alpha-antagonist activities in a yeast two-hybrid assay. Catechol and 4-acetamidoantipyrine inhibited the beta-galactosidase activity induced by 60 nM of TO901317 in an LXR alpha yeast assay, with IC20 values of 79,938.9 nM and 6286.4 nM, respectively. To the best of our knowledge, this is the first study to identify EDCs in reclaimed wastewater with LXR alpha-agonist/antagonist activity using the NRBE-HRMS method. (C) 2020 Elsevier B.V.
