Janus Kinase 2 (JAK2) is a kind of intracellular non-receptor protein tyrosine kinase and has been certified as an important target for the treatment of myeloproliferative neoplasms and rheumatoid arthritis. However, the low selectivity and potential safety issues restrict the clinical applications of JAK2 inhibitors. Here we found that crizotinib showed good inhibitory activity against JAK2 by enzymatic
Janus Kinase 2(JAK2)是一种细胞内非受体蛋白酪氨酸激酶,已被证明是治疗骨髓增生性肿瘤和类风湿关节炎的重要靶标。但是,低选择性和潜在的安全性问题限制了JAK2抑制剂的临床应用。在这里,我们发现克唑替尼通过酶促测定显示出对JAK2的良好抑制活性(IC50 = 27 nM)。然后,我们进行了基于结构的药物设计,并合成了具有氨基吡啶骨架的一系列化合物。最后,化合物12k和12l被确定为有前途的JAK2抑制剂,与JAK1和JAK3相比,它们对JAK2表现出高抑制活性(IC50 = 6 nM和3 nM),并且具有选择性,并且对HEL人红血球白血病细胞显示出强效的抗增殖活性。 。而且,
