Problems solved by technology

The treatment of RA is very difficult, so far, there is still a lack of safe and effective therapeutic drugs
Modern medicine is mainly about anti-inflammation and reducing sequelae. Drugs such as TNFα inhibitors Etanercept, Infliximab and Adalimumab can reduce some objective symptom indicators such as swelling and tender joint counts to 50% in some RA patients. Its non-response, or the failure of the second treatment, an average of about 10% of patients discontinued each year

Embodiment

[0019] The CIA model of DBA / 1 mice was established. DBA / 1 female mice for 6-8 weeks, after adaptive feeding for 1 week, use bovine type II collagen and complete Freund's adjuvant (BCG concentration: 4 mg / ml), after complete emulsification, inject 100 μL intradermally into the back skin near the caudal vertebra (containing 100 μg of bovine type II collagen), after 42 days, the mouse lower limbs (below the ankle joint) or upper limbs (below the wrist joint) can appear obvious redness and swelling, and the incidence rate is about 90%. 42 days after the initial immunization of DBA / 1 mice, the model mice were randomly divided into two groups, the papaya saponin I group and the control group, with more than 10 mice in each group. In the papaya saponin I group, the papaya saponin I was dissolved in 0.5% carboxymethylcellulose sodium (CMC-Na) to prepare a suspension, and the control group was prepared with 0.5% CMC-Na. The dosage of papaya saponin I is 8mg / kg. Oral administration, o...

Abstract

The invention relates to a small molecule compound for treating rheumatoid arthritis. The small molecule compound comprises the effective component which is Chonglou saponin I, wherein the concentration of the Chonglou saponin I is 0.1-10 microns. Animal experiments show that the Chonglou saponin I can reduce the joint injury and inflammation infiltration area of a mouse with collagen induction type rheumatoid arthritis and reduce bone mass defects and cartilage defects, ankle joint inflammatory injuries are reduced, and the syndromes of the rheumatoid arthritis can be improved. The inventionfurther discloses application of the Chonglou saponin I to preparation of medicine or health-care products for the rheumatoid arthritis.

Description

technical field [0001] The invention relates to a small molecule compound for treating rheumatoid arthritis, and proposes the application of the compound in preparing various forms of medicines or health food for preventing and treating rheumatoid arthritis. Background technique [0002] The prior art discloses that rheumatoid arthritis (Rheumatoid Arthritis, RA) is a chronic, systemic, progressive, autoimmune disease characterized by widespread persistent synovitis and symmetrical, destructive joint Lesions are characteristic. The treatment of RA is very difficult, so far, there is still a lack of safe and effective drugs. Modern medicine is mainly about anti-inflammation and alleviating sequelae. Drugs such as TNFα inhibitors Etanercept, Infliximab and Adalimumab can reduce some objective symptom indicators such as swelling and tender joint counts to 50% in some RA patients, but many patients still have problems in initial treatment. Its non-response, or the failure of t...
