As non-receptor tyrosine kinases, Janus kinases (JAKs) have become an attractive target for the treatment of autoimmune diseases and cancers. JAKs play a pivotal role in innate immunity, inflammation, and hematopoiesis by mediating the signaling of numerous cytokines, growth factors, and interferons (IFNs). Selective inhibitors of a variety of JAK members are expected to inhibit pro-inflammatory cytokine-mediated
作为非受体酪氨酸激酶,Janus激酶(JAKs)已成为治疗自身免疫性疾病和癌症的有吸引力的靶标。JAK通过介导多种细胞因子,生长因子和干扰素(IFN)的信号传导,在先天免疫,炎症和造血过程中发挥关键作用。各种JAK成员的选择性抑制剂有望抑制促炎性细胞因子介导的炎症和免疫反应,同时防止靶向其他亚型的JAK。在这项工作中,通过设计与JAK3中独特的半胱氨酸(Cys909)残基连接的共价结合链,将基于4-或6-苯基-嘧啶衍生物的选择性差的化合物改进为高效的选择性化合物。化合物12表现出有效的JAK3抑制活性(IC50 = 1。与其他JAK同工型(> 588倍)相比,具有极好的选择性。在细胞分析中,化合物12强烈抑制JAK3依赖性信号传导和T细胞增殖。此外,体内数据显示,化合物12在Balb / c小鼠中显着抑制了恶唑酮(OXZ)诱导的迟发型超敏反应。化合物12还显示出体面的药代动力学性质,并且适
