  Novel Small Molecule Bradykinin B₂ Receptor Antagonists

  摘要：

  Blockade of the bradykinin B, receptor provides therapeutic benefit in hereditary angioedema (HAE) and potentially in many other diseases. Herein, we describe the development of highly potent B, receptor antagonists with a molecular weight of approximately 500 g/mol. First, known quinoline-based B-2 receptor antagonists were stripped down to their shared core motif 53, which turned out to be the minimum pharmacophore. Targeted modifications of 53 resulted in the highly water-soluble lead compound 8a. Extensive exploration of its structure-activity relationship resulted in a series of highly potent B-2 receptor antagonists, featuring a hydrogen bond accepting functionality, which presumably interacts with the side chain of Asn-107 of the B-2 receptor, Optimization of the microsomal stability and cytochrome P450 inhibition eventually led to the discovery of the highly potent and orally available B-2 receptor antagonist 52e (JSM 10292), which showed the best overall properties.

  synthetic goal over the past several decades. Previously, our group reported phenanthroline-ligated perfluoroalkyl copper reagents, (phen)CuRF, which react with aryl iodides and aryl boronates to form the corresponding benzotrifluorides. Herein the perfluoroalkylation of a series of heteroaryl bromides with (phen)CuCF3 and (phen)CuCF2CF3 is reported. The mild reaction conditions allow the process to tolerate

  在过去的几十年里，将全氟烷基连接到有机化合物上一直是一个主要的合成目标。以前，我们的小组报道了菲咯啉连接的全氟烷基铜试剂 (phen)CuR F，它与芳基碘化物和芳基硼​​酸酯反应形成相应的三氟化苯。本文报道了一系列杂芳基溴化物与 (phen)CuCF 3和 (phen)CuCF 2 CF 3的全氟烷基化。温和的反应条件允许该过程耐受许多常见的官能团。使用 (phen)CuCF 2 CF 3 进行全氟乙基化的产率比使用 (phen)CuCF 3 进行三氟甲基化的产率略高，创建了一种生成氟代烷基杂芳烃的方法，这些杂芳烃不易从三氟乙酸衍生物中获得。

The synthesized compound for one of the predicted structures matched the purified compound in both chemical structure and AHR pharmacology. Our study provides evidence that kynurenine acts as an AHR

  细胞代谢物是重要的信号提示，但受复杂的未知化学作用。Kynurenine是一种色氨酸代谢产物，在癌症和免疫系统中起关键作用。尽管具有非典型的，非配体样的，高度极性的结构，但犬尿氨酸仍激活芳烃受体（AHR），这是一种PER，ARNT，SIM（PAS）家族转录因子，可响应多种环境和细胞配体。犬尿氨酸的活性通过孵育或长期保存而增加了100-1000倍，并且依赖于AHR的疏水配体结合袋，在激活前后，AHR的诱导具有相同的结构特征。我们纯化了犬尿氨酸的痕量活性衍生物，并鉴定了两种新型的密切相关的缩合产物，称为痕量延伸的芳香族缩合产物（TEACOP），在皮摩尔含量低时活跃。预测结构之一的合成化合物在化学结构和AHR药理学上均与纯化的化合物匹配。我们的研究提供了证据，犬尿氨酸作为AHR前配体，需要新的化学转化作用来作为受体激动剂。
