Abstract
The placenta contains 17β-hydroxysteroid dehydrogenase 1 (17β-HSD1), an enzyme critical for converting estrone to estradiol. Salicylates, widely used as preservatives, may inhibit 17β-HSD1, but their inhibitory strength and structure-activity relationships (SAR) remain unclear. This study evaluated 13 structurally diverse salicylates, identifying potent inhibitors of human and rat 17β-HSD1. Menthyl salicylate showed the strongest inhibition in humans (IC50: 5.23 μM) and rats (IC50: 14.85 μM). Inhibition correlated negatively with molecular weight, volume, carbon chain length, and LogP. Mechanistic studies revealed mixed/noncompetitive inhibition in both species. 3D-QSAR and molecular docking highlighted hydrophobic, van der Waals, and hydrogen-bonding interactions at the enzyme’s active site. Key structural features, including carbon chain length and substituent patterns, determined inhibitory potency. These findings clarify SAR and suggest salicylates' potential as endocrine disruptors.
期刊介绍:
The Journal of Steroid Biochemistry and Molecular Biology is devoted to new experimental and theoretical developments in areas related to steroids including vitamin D, lipids and their metabolomics. The Journal publishes a variety of contributions, including original articles, general and focused reviews, and rapid communications (brief articles of particular interest and clear novelty). Selected cutting-edge topics will be addressed in Special Issues managed by Guest Editors. Special Issues will contain both commissioned reviews and original research papers to provide comprehensive coverage of specific topics, and all submissions will undergo rigorous peer-review prior to publication.
