  Estrogenic diazenes: heterocyclic non-steroidal estrogens of unusual structure with selectivity for estrogen receptor subtypes

  摘要：

  Estrogens regulate many biological functions, often acting in a tissue-selective manner. Their tissue-selective action is believed to involve differential estrogen action through the two estrogen receptor (ER) subtypes, ERalpha and ERbeta, as well as differential interaction of the ligand-receptor complexes with promoters and coregulator proteins. In the latter case, selectivity is based on the induction of specific conformations of the ligand-ER complex, conformations that are influenced by the structure of the ligand. Estrogen pharmaceuticals having an ideal balance of tissue-selective activity are being sought for menopausal hormone replacement, breast cancer prevention and therapy, and other actions. To expand on the structural diversity of ER ligands that might show such tissue selectivity, we have prepared a series of diazenes (pyrazines, pyrimidines, and pyridazines) substituted with two to four aryl groups and various short-chain aliphatic substituents. All of the pyrazine and pyrimidines bind to ER, some with high affinity and with a considerable degree of preferential binding to either ERalpha or ERbeta. One pyrimidine and one pyrazine have ERalpha affinity preferences as high as 23 and 9, respectively, and one pyrimidine has an ERP affinity preference of 8. The pyridazines, by contrast, are quite polar and have only very low binding affinity for the ER. In cell-based transcription assays, several of the pyrimidines and a pyrazine were found to be considerably more agonistic on ERalpha than on ERbeta. Because these triaryl diazenes have the largest volumes among the ER ligands so far investigated, their high affinity demonstrates the flexibility of the ligand binding pocket of the ERs and its tolerance for large substituents. Thus, these novel heterocyclic ligands expand the repertoire of chemical structures that bind to the estrogen receptor, and they could prove to be useful in elucidating the biological behavior of the two ER subtypes and in forming the basis for new estrogen pharmaceuticals having desirable tissue selectivity.

  C3 / C5-烷基1,2,4-三芳基吡咯作为雌激素受体配体的合成及氧化降解研究

  摘要：

  在这项研究中，我们合成了1,2,4-三芳基吡咯作为雌激素受体（ER）的配体。制备了两个带有C3-烷基或C3 / C5-二烷基残基的吡咯系列。这两个系列的化合物都易于氧化降解，二烷基化化合物（t 1/2 = 33–66 h）的程度高于其单烷基化同类物（t 1/2 = 140–211 h）。然而，稳定性足以确定体外ER结合亲和力。在激素依赖性，ERα阳性的MCF-7 / 2a和U2-OS /α细胞中最活跃的激动剂是1,2,4-三（4-羟苯基）-3-丙基-1 H-吡咯（6 d） （MCF-7 / 2a：EC 50 = 70 n M ; U2-OS /α：EC 50 = 1.6 nM）。在U2-OS /β细胞中相应的无活性表现出较高的ERα选择性。在使用雌二醇（E2）以及纯化的hERα和hERβ蛋白的竞争实验中证实了这种趋势（计算6 d的相对结合亲和力（RBA）：RBA（ERα）= 1.85％； RBA（ERβ）<0

  A preseparated fermentation broth of Trichoderma atroviride strain 11 is analyzed by gas chromatography followed by mass-spectral detection using a Finnigan MAT GCQ apparatus. After preseparation in a C18 and a silica gel column, nineteen pyrone and dioxolane derivatives and two aliphatic esters are obtained, respectively. Among these, the four dioxolane derivatives have not been identified previously

  series of variously functionalized alkylbenzylketones. A large range of functional groups were well tolerated on the ortho‐, meta‐ and para‐positions by this mild process regardless of their electronic effects, demonstrating the general character of the present methodology. The trimethylsilylchloride/sodium iodide reducing process was also successfully applied to reduce α‐ketoacid and α‐ketoester substrates

  functionalization is a challenging but powerful tool in organic synthesis. Polarity-matched and sterically controlled hydrogen atom transfer (HAT) provides an excellent opportunity for site-selective functionalization. As such, the dual Ni/photoredox system was successfully employed to generate acyl radicals from aldehydes via selective formyl C–H activation and subsequently cross-coupled to generate ketones, a ubiquitous

  催化剂控制的位点选择性 C-H 功能化是有机合成中具有挑战性但功能强大的工具。极性匹配和空间控制的氢原子转移 (HAT) 为位点选择性功能化提供了极好的机会。因此，双镍/光氧化还原系统成功地用于通过选择性甲酰基 C-H 活化从醛生成酰基自由基，随后交叉偶联生成酮，这是绝大多数天然和生物活性分子中普遍存在的结构基序。然而，仅开发了少数限制使用芳基卤化物的例子。鉴于胺的广泛可用性，我们首次使用经济的镍和 TBADT 催化剂通过 C-N 键断裂开发了交叉偶联反应。一系列烷基和芳基醛与苄基和烯丙基吡啶盐交叉偶联，以提供具有广谱官能团耐受性的酮。即使在α-亚甲基羰基或α-氨基/氧基亚甲基存在下，也获得了对甲酰基C-H键的高区域选择性。
