尽管存在几种治疗选择,但是仍然需要针对多种自身免疫疾病的更有效,安全和方便的治疗方法。靶向Janus酪氨酸激酶(JAKs)在细胞信号传导反应中起着重要作用,并且可以促进与疾病相关的异常免疫功能,它已成为开发新型自身免疫性疾病疗法的一种新颖且有吸引力的方法。我们针对免疫细胞中的关键信号激酶JAK3筛选了我们的化合物文库,并鉴定了多个支架对该支架表现出良好的抑制活性。选择了特定的目标支架1 H-吡咯并[2,3- b ]吡啶系列(7-氮杂吲哚),部分基于结合亲和力(K i)以及细胞效能的基础上。该化学系列的优化导致鉴定出一种新型,有效和选择性的JAK3抑制剂VX-509(地加罗非尼),与大鼠移植模型(HvG)相比,它在大鼠宿主体内显示出良好的疗效。基于这些发现,看来VX-509为治疗多种自身免疫性疾病提供了潜力。
