  Discovery and structural characterization of peficitinib (ASP015K) as a novel and potent JAK inhibitor

  摘要：

  Janus kinases (JAKs) are considered promising targets for the treatment of autoimmune diseases including rheumatoid arthritis (RA) due to their important role in multiple cytokine receptor signaling pathways. Recently, several JAK inhibitors have been developed for the treatment of RA. Here, we describe the identification of the novel orally bioavailable JAK inhibitor 18, peficitinib (also known as ASP015K), which showed moderate selectivity for JAK3 over JAK1, JAK2, and TYK2 in enzyme assays. Chemical modification at the C4-position of lead compound 5 led to a large increase in JAK inhibitory activity and metabolic stability in liver microsomes. Furthermore, we determined the crystal structures of JAK1, JAK2, JAK3, and TYK2 in a complex with peficitinib, and revealed that the1H-pyrrolo [2,3-b]pyridine-5-carboxamide scaffold of peficitinib forms triple hydrogen bonds with the hinge region. Interestingly, the binding modes of peficitinib in the ATP-binding pockets differed among JAK1, JAK2, JAK3, and TYK2. WaterMap analysis of the crystal structures suggests that unfavorable water molecules are the likely reason for the difference in orientation of the 1H-pyrrolo[2,3-b]pyridine-5-carboxamide scaffold to the hinge region among JAKs.

  The present invention provides a compound of formula (I) having an excellent JAK3 inhibition activity and being useful as an active ingredient of an agent for treating and/or preventing various immune diseases including autoimmune diseases inflammatory diseases, and allergic diseases. The compound according to the present invention has an inhibition activity against JAK3 and is thus useful as an active ingredient of an agent for treating or preventing diseases caused by undesirable cytokine signal transmission (e.g., rejection during organ/tissue transplantation, autoimmune diseases, multiple sclerosis, rheumatoid arthritis, psoriasis, asthma, atopic dermatitis, Alzheimer's disease, and atherosclerotic disease), or diseases caused by abnormal cytokine signal transmission (e.g., cancer and leukemia).

  本发明提供了一种化合物(I)的公式，具有优异的JAK3抑制活性，并可用作治疗和/或预防各种免疫疾病，包括自身免疫性疾病、炎症性疾病和过敏性疾病的活性成分。根据本发明的化合物具有抑制JAK3的活性，因此可用作治疗或预防由不良细胞因子信号传递引起的疾病的活性成分（例如，在器官/组织移植期间的排斥反应、自身免疫性疾病、多发性硬化症、类风湿性关节炎、牛皮癣、哮喘、特应性皮炎、阿尔茨海默病和动脉粥样硬化疾病），或由异常细胞因子信号传递引起的疾病（例如癌症和白血病）。
