Description

CYAN-SUBSTITUTED CYCLIC HYDRAZINE DERIVATIVE AND APPLICATION THEREOF nc Lrnn / zznz / B / Yu FIELD OF INVENTION The present invention pertains to the field of drug synthesis and, in particular, the present invention relates to a JAK inhibitor, its method of preparation and its use. BACKGROUND OF THE INVENTION Protein kinases are a class of enzymes that catalyze the phosphorylation of proteins and are key factors in the regulation of cell signals such as cell proliferation and cell differentiation, including cell growth, survival, differentiation, organogenesis, morphogenesis, neovascularization, tissue repair and regeneration, etc. The signal transduction of many cytokines, such as the interferon (IFN) family, the glycoprotein 130 (gpl30) family, the γ-C family (common gamma chain, CD132 family), and the single-chain family, involves the Janus kinase (JAK) family, as well as JAK downstream signal transducers and activators of transcription (STATs). Currently, there are four known members of the JAK family in mammals: JAK1 (also known as Janus kinase-1), JAK2 (also known as Janus kinase-2), JAK3 (also known as Janus kinase-3), and TYK2 (also known as protein tyrosine kinase 2). Blocking JAK signal transduction offers a promising avenue for developing therapeutic approaches for inflammatory diseases, autoimmune diseases, bone marrow proliferative disorders, and cancer. JAK inhibition also contributes to the treatment of immune-mediated skin diseases such as psoriasis and skin sensitization. Toficitinib and baricitinib, which have been launched, are used to treat rheumatoid arthritis; ruxolitinib is used to treat bone marrow fibrosis and acute graft-versus-host disease. However, some JAK inhibitors also have some evident side effects and toxicities. JAK inhibitors can cause immune-related side effects: infection, including pneumonia, viral infection (such as herpes zoster), bacterial infection, actinomycosis (mycobacterial infection), fungal infection, decreased immunity (such as reduced NK cells), and anemia. However, there are also some non-immunological side effects, such as pulmonary embolism (which can be fatal). Studies have shown that existing JAK inhibitors are not selective for members of the JAK kinase family, and their pulmonary embolism side effect is related to JAK2 inhibition. In short, there is an urgent need in this field to develop inhibitors of Janus kinases or related kinases, especially inhibitors with high selectivity for JAK1. nr Lrnn / zznz / E / YiAi BRIEF DESCRIPTION OF THE INVENTION The purpose of the present invention is to provide a novel inhibitor with high activity for JAK1 and high selectivity for JAK2, as well as the method of preparing and using the same.
