  摘要：

  Here, we examine the significance that stereochemistry plays within the clinically relevant Janus kinase 3 (Jak3) inhibitor 1 (CP-690,550). A synthesis of all four enantiopure stereoisomers of the drug was carried out and an examination of each compound revealed that only the enantiopure 3R,4R isomer was capable of blocking Stat5 phosphorylation (Jak3 dependent). Each compound was profiled across a panel of over 350 kinases, which revealed a high level of selectivity for the Jak family kinases for these related compounds. Each stereoisomer retained a degree of binding to Jak3 and Jak2 and the 3R,4S and 3S,4R stereoisomers were further revealed to have binding affinity for selected members of the STE7 and STE20 subfamily of kinases. finally, an appraisal of the minimum energy conformation of each stereoisomer and molecular docking at Jak3 was performed in an effort to better understand each compounds selectivity and potency profiles.

  Discovery of 3,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridin-2(1H)-one derivatives as novel JAK inhibitors

  摘要：

  Because Janus kinases (JAKs) play a crucial role in cytokine-mediated signal transduction, JAKs are an attractive target for the treatment of organ transplant rejection and autoimmune diseases such as rheumatoid arthritis (RA). To identify JAK inhibitors, we focused on the 1H-pyrrolo[2,3-b]pyridine derivative 3, which exhibited moderate JAK3 and JAK1 inhibitory activities. Optimization of 3 identified the tricyclic imidazo-pyrrolopyridinone derivative 19, which exhibited potent JAK3 and JAK1 inhibitory activities (IC50 = 1.1 nM, 1.5 nM, respectively) with favorable metabolic stability.

  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。
