  Discovery of a Non-Estrogenic Irreversible Inhibitor of 17β-Hydroxysteroid Dehydrogenase Type 1 from 3-Substituted-16β-(m-carbamoylbenzyl)-estradiol Derivatives

  摘要：

  17 beta-Hydroxysteroid dehydrogenase type 1 (17 beta-HSD1) is thought to play a pivotal role in the progression of estrogen-sensitive breast cancer by transforming estrone (E1) into estradiol (E2). We designed three successive series of E2-derivatives at position C3 of the potent inhibitor 16 beta-(m-carbamoylbenzy1)-E2 to remove its unwanted estrogenic activity. We report the chemical synthesis and characterization of 20 new E2-derivatives, their evaluation as 17 beta-HSD1 inhibitors, and their proliferative (estrogenic) activity on estrogen-sensitive cells. The structure-activity relationship study provided a new potent and steroidal nonestrogenic inhibitor of 17 beta-HSD1 named 3-{[(16 beta,17 beta)-3-(2-bromoethyl)-17-hydroxyestra-1(10),2,4-trien-16-yl]methyl}benzamide (23b). In fact, this compound inhibited the transformation of E1 into E2 by 17 beta-HSD1 in T-47D cells (IC50 = 83 nM), did not inhibit 17 beta-HSD2, 17 beta-HSD7, 17 beta-HSD12, and CYP3A4, and did not stimulate the proliferation of estrogen-sensitive MCF-7 cells. We also discussed the results of kinetic and molecular modeling (docking) experiments, suggesting that compound 23h is a competitive and irreversible inhibitor of 17 beta-HSD1.

  PBRM with a high-HPLC-grade purity (99.7%) after recrystallization. Important improvements have been achieved in this sequence from previously reported routes (A and B). Notably, we used a palladium-catalyzed Suzuki–Miyaura cross-coupling reaction to rapidly install the requested C3 chain on estrone. Also, catalytic hydrogenation of the C16-enone was shortened by half using Pearlman’s catalyst. Finally

• Crucial Role of 3-Bromoethyl in Removing the Estrogenic Activity of 17β-HSD1 Inhibitor 16β-(<i>m</i>-Carbamoylbenzyl)estradiol

  17 beta-Hydroxysteroid dehydrogenase type 1 (17 beta-HSD1) represents a promising therapeutic target for breast cancer treatment. To reduce the undesirable estrogenic activity of potent 17 beta-HSD1 inhibitor 16 beta-(m-carbamoylbenzyl)estradiol (1) (IC(50) = 27 nM), a series of analogues with a small functionalized side chain at position 3 were synthesized and tested. The 3-(2-bromoethyl)-16 beta-(m-carbamoylbenzy1)-estra-1,3,5(10)-trien-17 beta-ol (5) was found to be a potent inhibitor (IC(50) = 68 nM) for the transformation of estrone (E1) into estradiol (E2) and, most importantly, did not stimulate the proliferation of estrogen-sensitive MCF-7 cells, suggesting no estrogenic activity. From these results, the crucial role of a bromoalkyl side chain at carbon 3 was identified for the first time. Thus, this new inhibitor represents a good candidate with an interesting profile suitable for further studies including pharmacokinetic and in vivo studies.
