Description

Nitrogen-containing heteroaromatic derivative regulator, preparation method and application thereof

The invention belongs to the field of drug synthesis, and specifically relates to a JAK inhibitor, a preparation method and application thereof.

Janus kinase (JAK) is an intracellular non-receptor tyrosine kinase that mediates the signal transduction and activation of various cytokines. The JAK kinase family contains four subfamily members of JAK1, JAK2, JAK3 and TYK2. Each subfamily member mediates different types of cytokine signaling pathways. JAK1, JAK2 and TYK2 are expressed in all tissues and cells of the human body, and JAK3 is mainly expressed In the cells of each hematopoietic tissue. The common feature of cytokine receptors is that the receptor itself does not have kinase activity, but the intracellular segment of the receptor has a binding site for tyrosine kinase JAK. When the cytokine receptor binds to its ligand, the receptor-coupled JAKs are activated, and the receptor is phosphorylated. The phosphorylated tyrosine site can bind to the STAT protein containing the SH2 domain, so that STAT is Recruited to the receptor and phosphorylated by JAKs, and then phosphotyrosine mediates STAT dimerization. The activated STAT dimer transfers to the nucleus and activates the transcription of its target genes, thereby regulating the growth, activation, and differentiation of a variety of cells And many other functions.

The JAK/STAT signal pathway mediates the signal transduction of most cytokines in cells, and plays a key role in the biological processes of immune regulation and immune cell proliferation. The JAK/STAT signaling pathway has a wide range of functions, and is involved in many important biological processes such as cell proliferation, differentiation, apoptosis and immune regulation. It is related to various inflammatory diseases such as rheumatoid arthritis, dermatitis, psoriasis, and inflammatory bowel disease. (Ulcerative colitis and Crohn’s disease) are closely related; at the same time, the JAK/STAT signaling pathway is closely related to tumorous diseases such as myelofibrosis, polycythemia vera and essential thrombocythemia, and mutations in the JAK molecule itself are also closely related. Can cause acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), ductal breast carcinoma and non-small cell lung cancer (NSCLC) and other neoplastic diseases.

Inflammatory bowel disease is a chronic intestinal inflammatory disease, including ulcerative colitis (UC) and Crohn’s disease (CD). At present, the main drugs for the treatment of inflammatory bowel disease are aminosalicylic acid preparations, glucocorticoids, immunosuppressants, antibiotics and so on. The main principle of the treatment of UC is to regulate the immune response and inhibit inflammation. At present, in clinical practice, sulfasalazine is mainly used to treat mild to moderate UC. The current commonly used drugs for moderate to severe UC include glucocorticoids, but because the risks outweigh the benefits, they will not be used as long-term treatments. Monoclonal antibodies have problems with drugs, which are expensive, the production of drug antibodies affects the safety and effectiveness of drugs, and the way of intravenous administration is not convenient. There are still far unsatisfied medical needs in this field. Many patients receiving treatment have not yet been relieved, and up to 80% of Crohn’s disease patients and 30% of UC patients will eventually need surgery.

Tofacitinib (Xeljanz) is the first oral JAK inhibitor for the treatment of adult patients with moderately to severely active UC. It has significant inhibitory activity against JAK 1, 2, and 3 subtypes, which increases the efficacy of tofacitinib, but it also brings A more serious side effect. Adverse reactions include infection, tuberculosis, tumor, anemia, liver damage, and increased cholesterol. Tofacitinib's instructions have many black boxes: serious infections (tuberculosis, bacteria, fungi, viruses) and malignant tumors (lymphoma, etc.). Due to the wide range of functions mediated by each JAK, these side effects are caused by the drug simultaneously inhibiting multiple JAKs. Because JAK is widely involved in the regulation of immune cells, JAK inhibitors will inevitably cause side effects related to immunosuppression, such as serious infections and even tumors. Even with the many highly selective inhibitors currently under research, this side effect caused by the inhibitory target is inevitable.

In view of the good efficacy of JAK inhibitors and the serious side effects associated with multiple targets, the development of a safer JAK inhibitor drug has become an urgent problem to be solved. Since inflammatory bowel disease occurs on the surface of the intestinal lumen of the gastrointestinal tract, it does not require the drug to enter the blood system to function. Therefore, a drug that reduces the systemic exposure of the drug in the blood circulation and increases the local exposure of the drug at the inflammation site has been developed. Become a good strategy to improve security. International application WO2017189822A1 reports that Theravance company has synthesized a series of compounds. These compounds have extremely low system exposure and are enriched in intestinal inflammatory parts, which can effectively treat intestinal inflammation without causing serious side effects. , Indicating that the strategy has great feasibility and may produce significant clinical application value.
