  使用原位稳定互变异构体形式的多官能化N1-烷基化7-氨基-6-氮杂吲哚衍生物的简单方法

  摘要：

  开发并研究了一种合成多官能化N1-烷基7-氨基-6-氮杂吲哚衍生物的简单方法。使用分子内还原环化作为关键步骤，分别形成了5-氨基-和7-氨基-6-氮杂-2-氧吲哚12a和13a。随后在12a中将吡咯N1原子烷基化，得到所需的N1-烷基化化合物22a-24，其官能度不同。在与用于12a相同的条件下5-氨基取代的区域异构体13a的烷基化未产生N1-烷基化的产物。为了找到观察到的反应性差异的合理解释，我们研究了可能的互变异构体图12a和13a以及它们的中性和离子化形式在气相中的分布。测定了化合物12a和23的相关理化性质。

We report here the synthesis and biological activity of eight novel scaffolds, including imidazopyridines, benzothiazoles and benzoxazoles.

  compounds share a common 7H‐pyrrolo[2,3‐d]pyrimidine hinge binding motif, and little is known about modifications tolerated at this heterocyclic core. In the current study, a library of tofacitinib bioisosteres was prepared and tested against JAK3. The compounds possessed the tofacitinib piperidinyl side chain, whereas the hinge binding motif was replaced by a variety of heterocycles mimicking its pharmacophore

  Janus激酶（JAKs）是关键参与细胞因子信号传导的胞质酪氨酸激酶家族。JAK已被证明是治疗炎症和骨髓增生性疾病的有效靶标，两种抑制剂托法替尼和鲁索替尼最近获得了市场许可。尽管取得了成功，但JAK系列中的选择性仍然是一个主要问题。两种批准的化合物都具有共同的7 H-吡咯并[2,3- d]嘧啶铰链结合基序，关于在该杂环核心上耐受的修饰知之甚少。在当前的研究中，制备了托法替尼生物等排体库并针对JAK3进行了测试。这些化合物具有托法替尼哌啶基侧链，而铰链结合基序被模仿其药效基团的各种杂环所取代。考虑到从分子模型获得的希望，大多数化合物被证明是活性很差的。然而，发现了在这一系列新型化学型中恢复活性的策略，并推论出关键的结构-活性关系。提出的化合物可作为开发新型JAK抑制剂的起点，并可作为计算机模拟模型的有价值的训练集。
