Description

technical field [0001] The present invention relates to a compound containing heterocycle, its application and composition containing it. Background technique [0002] Rheumatoid arthritis is a chronic systemic autoimmune disease characterized by joint synovial inflammation. Its incidence is about 1% of the total adults. Its main manifestations are symmetrical multiple recurrent arthritis, and the small joints of the hands and feet are most likely to be involved. Early or acute onset joints are mostly red, swollen, hot, painful and movement disorder; late stage can lead to joint destruction, stiffness, deformity and loss of function, as well as osteoporosis and skeletal muscle atrophy. Throughout the course of the disease, it may be accompanied by fever, anemia, weight loss, vasculitis, subcutaneous nodules and other lesions, and may also involve multiple organs throughout the body. It is a disease with a high disability rate and significantly increases the patient's morta...
