Description

2, 4-disubstituted pyrimidine derivative, preparation method and application thereof
Technical Field
The invention relates to a 2, 4-disubstituted pyrimidine derivative, a preparation method and application thereof, belonging to the field of chemical medicine.
Background
Over the last 20 years, new therapies for the treatment of autoimmune diseases have evolved rapidly, with impressive success in terms of biologicals. Inhibition of different cytokine pathways can cope with different situations, and has proved to have good therapeutic effects. For example, anti-IL 12/IL23 or more selective anti-IL 23 therapies have been approved for the treatment of psoriasis and psoriatic arthritis, which exhibit significant efficacy and good safety profiles, and are now approved for use in the treatment of crohn's disease patients in europe and the united states. Inflammatory bowel disease (Inflammatory bowel disease, IBD) is a recurrent disease characterized by chronic inflammation of the gastrointestinal tract, which is commonly affected by both genetic and environmental factors, resulting in diarrhea and abdominal pain. The main types of IBD are Crohn's Disease (CD) and Ulcerative Colitis (UC). Typically, patients require life-long medication and other procedures depending on the severity of the disease. Studies have shown that about 25% of patients with crohn's disease will require additional bowel surgery within 5 years after the first treatment. The risk of requiring surgery after diagnosis has been reduced over the last 60 years, but is still a significant burden. Since 1997, treatments for IBD have been mainly using steroids to induce remission and immunomodulatory drugs such as azathioprine, mercaptopurine, and methotrexate to maintain remission. anti-Tumor Necrosis Factor (TNF) infliximab is effective in treating IBD, resulting in a shift in treatment pattern. However, up to one third of patients receiving anti-tumor necrosis factor treatment are major non-responders, while a significant portion (10% -15% per year) is lost due to antibody formation (immunogenicity failure). In addition, these biological agents are associated with significant adverse events such as opportunistic infections and immune complications. With our knowledge of the major inflammatory pathways of inflammatory bowel disease, a variety of new therapeutic approaches are becoming possible. These include the development of new oral drugs, inhibiting cytokine signaling, lymphocyte influx and mast cell activity, and promoting the activity of innate immunosuppressive pathways for specific pathways found to be associated with other immune-mediated diseases. There remains a great clinical need for new effective, tolerated, economical and oral drugs.
JAK (JAK) is a family of intracellular tyrosine kinases with four known members JAK1, JAK2, JAK3 and TYK2, which are associated with various cytokine-mediated signal transduction pathways. Upon binding of the ligand to its corresponding receptor, JAK activation will be induced, followed by receptor phosphorylation. Activated JAKs phosphorylate signal transduction and transcriptional activator proteins (signal transducer and activator of transcription, STAT), which form dimers, translocate to the nucleus, promoting cytokine response gene expression. JAK kinase inhibitors are small molecule drugs that are currently marketed or under development for the treatment of several immune diseases, including psoriasis, rheumatoid arthritis (rheumatoid arthritis, RA) and IBD. It has been demonstrated that different cytokine receptors are associated with heterodimers or homodimers of specific JAK enzymes, and that each JAK is linked to more than one receptor. In mammals, JAK1, JAK2 and TYK2 are widely expressed, except that JAK3 is mainly expressed in hematopoietic cells. JAK1 is the most widely expressed JAK kinase because it is involved in the signaling process of a variety of cytokines, such as gamma common, yc, gp130, type I interferon (IFN-a/β) and type II interferon (IFN- γ), IL-6 and IL-10 families, and is thus involved in Rheumatoid Arthritis (RA), inflammation and immunodeficiency. JAK2 is the only JAK family member paired with itself. JAK2 plays a decisive role in myelopoiesis, erythropoiesis, megakaryopoiesis and mammary gland development by forming unique homodimers through signal transduction associated with cytokines IL-3, IL-5, granulocyte-macrophage colony stimulating factor (granulocyte macrophage colony-stimulating factor, GM-CSF), erythropoietin (EPO) and Thrombopoietin (TPO). The absence of JAK3 may lead to indications of some immune systems such as rheumatoid arthritis, graft rejection and severe combined immunodeficiency of the X-linkage.
TYK2 is paired with JAK2, through its signaling pathways with IL-12 and IL-23, which interact with the IL-12 receptor β1 receptor chain, and coordinates phosphorylation of STAT3 and STAT4. Clinical data indicate that there is a need to reduce activity on JAK2 in HWB to reduce the risk of hematopoietic effects. Human Tyk2 gene deficiency can lead to defective signaling of various cytokines (including IL-6, IL-10, IL-12 and IL-23) and reduced IFNγ production; and the lack of TYK2 expression is manifested in a significant imbalance in the signaling attenuation of various pro-inflammatory cytokines and helper T cell differentiation. TYK2 deficiency is clinically diagnosed as hyper-IgE Syndrome (HIEs) and chronic mucosal cutaneous candidiasis (chronic mucocutaneous candidiasis, CMC). Given the importance of TYK 2-dependent downstream cytokine signaling in this and other diseases (such as rheumatoid arthritis and crohn's disease), selective TYK2 inhibitors are the most potential small molecule inhibitors for the treatment of immune diseases.
