  Novel inhibitors of 17β-hydroxysteroid dehydrogenase type 1: Templates for design

  摘要：

  The 17 beta-hydroxysteroid dehydrogenases (17 beta-HSDs) catalyze the interconversion between the oxidized and reduced forms of androgens and estrogens at the 17 position. The 17 beta-HSD type 1 enzyme (17 beta-HSD1) catalyzes the reduction of estrone (E1) to estradiol and is expressed in malignant breast cells. Inhibitors of this enzyme thus have potential as treatments for hormone dependent breast cancer. Syntheses and biological evaluation of novel non-steroidal inhibitors designed to mimic the E1 template are reported using information from potent steroidal inhibitors. Of the templates investigated biphenyl ethanone was promising and led to inhibitors with IC50 values in the low micromolar range. (C) 2008 Elsevier Ltd. All rights reserved.

• Bicyclic Substituted Hydroxyphenylmethanones as Novel Inhibitors of 17β-Hydroxysteroid Dehydrogenase Type 1 (17β-HSD1) for the Treatment of Estrogen-Dependent Diseases

  Estradiol (E2), the most important estrogen in humans, is involved in the initiation and progression of estrogen-dependent diseases such as breast cancer and endometriosis. Its local production in the target cell is regulated by 17 beta-hydroxysteroid dehydrogenase type 1 (17 beta-HSD1), which catalyzes E2-formation by reduction of the weak estrogen estrone (E1). Because the enzyme is expressed M the diseased tissues, inhibition of 17 beta-HSD1 is considered as a promising therapy for the treatment of estrogen-dependent diseases. For the development of novel inhibitors, a structure-and ligand-based design strategy was applied, resulting in bicyclic substituted hydroxyphenylmethanones. In vitro testing revealed high inhibitory potencies toward human placental 17 beta-HSD1. Compounds were further evaluated with regard to selectivity (17 beta-HSD2, estrogen receptors ER alpha and ER beta), intracellular activity (T47D cells), and metabolic stability. The most promising compounds, 14 and 15, showed IC50 values in the low nanomolar range in the cell-free and cellular assays (8-27 nM), more than 30-fold selectivity toward 17 beta-HSD2 and no affinity toward the ERs. The data obtained make these inhibitors interesting candidates for further preclinical evaluation.
