Description

technical field [0001] The invention relates to a JAK kinase inhibitor containing a 4-amino-(1H)-pyrazole structure, a preparation method and application thereof, and belongs to the technical field of organic compound synthesis and medical application. Background technique [0002] The JAK / STAT signaling pathway plays an important physiological role in autoimmunity, hematopoiesis, and tumorigenesis. The abnormality of JAK / STAT signaling pathway will induce diseases such as immunodeficiency, inflammation and tumor. Some tumors are accompanied by the continuous activation of JAKs kinases. Dysregulation of JAK2 isoforms is frequently found in patients with osteoproliferative neoplasms and childhood T-cell acute lymphoblastic leukemia. Hematologic malignancies such as malignant lymphoma and myeloproliferative disorders are associated with mutations in JAK2 subtypes. Binding of certain growth factors and cytokines to their receptors can stimulate JAKs to phosphorylate STAT3. ...
