  Estrogen Receptor Modulators:  Identification and Structure−Activity Relationships of Potent ERα-Selective Tetrahydroisoquinoline Ligands

  摘要：

  As part of a program aimed at the development of selective estrogen receptor modulators (SERMs), tetrahydroisoquinoline derivative 27 was discovered by high throughput screening. Successive replacements of the p-F substituent of 27 by an aminoethoxy side chain and of the 1-H of the tetrahydroisoquinoline core by a 1-Me group provided analogues 19 and 20. These compounds showed potencies in a cell-based reporter gene assay (ERE assay) varying between 0.6 and 20 nM and displayed antagonist behaviors in the MCF-7 human breast adenocarcinoma cell line with IC(50)s in the range of 2-36 nM. The effect of N-phenyl substituents on the activity and pharmacokinetic properties of tetrahydroisoquinoline analogues was explored. As a result of this investigation, two potent derivatives bearing a p-F N-aryl group, 19c and 20c, were discovered as candidates suitable for further profiling. To gain insight into the ligand-receptor interaction, the X-ray crystallographic structure of the 1-H tetrahydroisoquinoline derivative (R)-18a in complex with ERalpha-ligand binding domain (LBD)(301-553)/C-->S triple mutant was solved to 2.28 Angstrom. An overlay of this X-ray crystal structure with that reported for the complex of ERalpha-LBD301-553/carboxymethylated C and raloxifene (5) shows that both compounds bind to the same cleft of the receptor and display comparable binding modes, with differences being observed in the conformation of their "D-ring" phenyl groups.

  摘要：

  我们在此公开了四氢异喹啉系列的雌激素受体α（ERalpha）选择性雌激素受体调节剂（SERM）的发现，该调节剂结合了新颖的构象受限的侧链以取代典型的SERM氨基乙氧基残基。与雷洛昔芬（7）结合使用ERalpha配体结合域（LBD）的X射线晶体结构进行的分子模型研究表明，二氮杂萘啉部分是SERM侧链的可行模拟物。基于此知识，我们的先导化合物60的哌啶基乙氧基部分被二氮杂萘啉亚基取代，提供了新型的四氢异喹啉29。除了在雌激素反应元件和MCF-7分析中对ERalpha具有结合亲和力和拮抗特性外，与母体化合物60相似，在不存在17β-雌二醇的情况下，MCF-7分析中，配体29的激动剂行为降低。这些数据表明29在体内可能具有预防/治疗乳腺癌的潜力，这一特性在寻求激素替代疗法的安全替代方案时特别具有吸引力。在大鼠进行的药代动力学实验中，有29个显示出有趣的特征，生物利用度为49％。我们还公开了与ERa

On the basis of this knowledge, the piperidinylethoxy moiety of our lead compound 60 was replaced by a diazadecaline subunit, providing the novel tetrahydroisoquinoline 29. In addition to exhibiting a binding affinity to ERalpha and antagonistic properties in the estrogen response element and MCF-7 assays similar to those of the parent compound 60, ligand
