  New Insights into the SAR and Binding Modes of Bis(hydroxyphenyl)thiophenes and -benzenes: Influence of Additional Substituents on 17β-Hydroxysteroid Dehydrogenase Type 1 (17β-HSD1) Inhibitory Activity and Selectivity

  摘要：

  17 beta-Hydroxystcroid dehydrogenase type 1 (17 beta-HSD1) is responsible for the catalytic reduction of weakly active E1 to highly potent E2. E2 stimulates the proliferation of hormone-dependent diseases via activation of the estrogen receptor alpha (ER alpha). Because of the overexpression of 17 beta-HSD1 in mammary tumors, this enzyme should be an attractive target for the treatment of estrogen-dependent pathologies. Recently, we have reported on a series of potent 17 beta-HSD1 inhibitors: bis(hydroxyphenyl) azoles, thiophenes, and benzenes. In this paper, different substituents are introduced into the core structure and the biological properties of the corresponding inhibitors are evaluated. Computational methods and analysis of different X-rays of 17 beta-HSD1 lead to identification of two different binding modes for these inhibitors. The fluorine compound 23 exhibits an IC50 of 8 nM and is the most potent nonsteroidal inhibitor described so far. It also shows a high selectivity (17 beta-HSD2, ER alpha) and excellent pharmacokinetic properties after peroral application to rats.

  摘要：

  描述了易于获得的2,5-二溴噻吩的单锅卤舞/ Negishi交叉偶联。二异丙基氨基锂（LDA）介导的卤素舞反应导致形成热力学稳定的α-硫代二溴噻吩，将其与ZnCl 2进行金属转移，并进行Negishi交叉偶联，以在一个锅中提供相应的芳基化二溴代噻吩。所得的β-溴基团比其余的α-溴基团反应性要低得多，后者用于一锅双Suzuki-Miyaura交叉偶联，可轻松合成多芳基噻吩。

  One‐pot halogen dance/Negishi cross‐coupling of readily available 2,5‐dibromothiophenes is described. A lithium diisopropylamide (LDA)‐mediated halogen dance reaction resulted in the formation of thermodynamically stable α‐lithiodibromothiophenes, which were transmetalated with ZnCl2 and subjected to Negishi cross‐coupling to provide the corresponding arylated dibromothiophenes in one pot. The resultant
