Description

Composition for preventing or treating arthritis comprising (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-G]chromen-7-yl-ester as an active ingredient

[0001] The present invention relates to a composition for preventing or treating arthritis, and more specifically, to a composition for preventing or treating arthritis comprising (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester as an active ingredient.

[0002] Arthritis is a general term for several diseases that cause damage to joints, including osteoarthritis (OA), rheumatoid arthritis, gout, and psoriatic arthritis. 85% of arthritis patients suffer from osteoarthritis.

[0003] Osteoarthritis is a disease that is accompanied by pain, stiffness, swelling, and decreased function. It is known that various factors, such as inflammation of the synovium surrounding the cartilage and changes in chondrocytes, reduce the production of extracellular matrix and increase the activity of extracellular matrix-degrading enzymes, accelerating their degradation. As a result, the basic structure of cartilage is destroyed, and the joints become unable to withstand the load, resulting in joint deformation. This type of osteoarthritis is known to occur mainly in the knees, hip joints, hands, and spine.

[0004] Rheumatoid arthritis is an autoimmune disease that causes inflammation by attacking the body's own joints due to an abnormality in the immune system. It is a chronic, systemic inflammatory disease that causes pain and swelling in joints such as the fingers, hands, feet, wrists, ankles, and knees, and can also cause abnormalities in various other organs such as the muscles, skin, lungs, and eyes.

[0005] Current clinical treatments include medications such as steroids, non-steroidal anti-inflammatory drugs (NSAIDs), and analgesics, as well as chondroprotectors such as hyaluronic acid, glucosamine, and chondroitin. However, these drug treatments have drawbacks, such as upper gastrointestinal bleeding, cardiovascular toxicity, and addiction, which hinder long-term use, as well as limited anti-inflammatory effects. Furthermore, chondroprotectors only protect joints by providing nutrients to cartilage cells or alleviating septal defects, and do not fundamentally treat arthritis.

[0006] Surgical treatment methods include arthroscopic surgery, high tibial osteotomy, partial joint replacement, and total knee replacement, but they cause significant pain and discomfort to patients. Therefore, there is a continuing demand for the development of treatments that minimize the side effects of drug treatments and minimize patient pain and discomfort while still having a definite effect.

[0007] The purpose of the present invention is to provide a pharmaceutical composition and a health functional food composition having excellent effects in preventing, improving or treating arthritis.

[0008] In order to achieve the above purpose, the present invention provides a pharmaceutical composition for preventing or treating arthritis, comprising (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester or a pharmaceutically acceptable salt thereof as an active ingredient.

[0009] The present invention provides a health functional food composition for preventing or improving arthritis, comprising (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester or a food-related acceptable salt thereof as an active ingredient.

[0082]

[0083] <Experimental Method>

[0084] 1. Cell culture

[0085] MH7A cells, a human synovial fibroblast cell line, were cultured in RPMI (Roswell Park Memorial Institute) 1640 medium containing 10% FBS, 120 μg / mL penicillin, and 200 μg / mL streptomycin at 37°C in a humidified incubator with 5% CO2.

[0086]

[0087] 2. Enzyme-linked immunosorbent assay (ELISA)

[0088] To determine the effect of (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester (CGK012) on the expression of inflammatory cytokines and substrate-degrading enzymes, enzyme-linked immunosorbent assay (ELISA) was performed. MH7A cells were seeded in 12-well plates at a density of 5 × 10 per well. 4 After dividing the cells, they were cultured for 24 hours. After treatment with 5, 10, and 20 μM of CGK012 together with tumor necrosis factor-α (TNF-α) (10 ng / mL) for 24 hours, the culture medium was collected, centrifuged at 4°C and 8,000 rpm for 5 minutes to remove cell debris, and the supernatant was used for analysis.

[0089] ELISA kits for IL-1β, IL-6, IL-8, MMP-1, and MMP-3 were purchased from ThermoFisher Scientific and enzyme-linked immunosorbent assays were performed according to the manufacturer's instructions. First, the plates coated with each antibody were washed, and the culture medium supernatant and standard substances were dispensed and reacted at room temperature for 2 hours. Then, the color reaction was induced by sequential reaction with the detection antibody (HRP-conjugated antibody) and the detection substrate (TMB). After the reaction was terminated with 0.16 M sulfuric acid, the absorbance was measured at 450 nm using a plate reader. The concentrations were calculated using a standard curve generated with the standard solutions for IL-1β, IL-6, IL-8, MMP-1, and MMP-3, respectively.

[0090]

[0091] <Experimental Example 1> Confirmation of the inhibitory effect on the expression of inflammatory cytokines by treatment with (7S)-(+)-cyclopentyl carbamic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester (CGK012).

[0092] Increased expression of inflammatory cytokines is a major cause of arthritis. Therefore, the effect of CGK012 on the expression of inflammatory cytokines induced by tumor necrosis factor-alpha (TNF-α) in MH7A cells, a synovial cell line derived from arthritis patients, was analyzed using ELISA.

[0093] As a result, as shown in Fig. 1, it was confirmed that the expression of inflammatory cytokines IL-1β, IL-6, and IL-8 increased by TNF-α was reduced by CGK012.

[0094]

[0095] <Example 2> Confirmation of the inhibitory effect of CGK012 on substrate-degrading enzyme expression.

[0096] Cartilage matrix degradation by activation of matrix-degrading enzymes is known to be a hallmark of arthritis. Therefore, the effect of CGK012 on the expression of matrix metalloproteinases (MMP-1) and matrix metalloproteinase (MMP-3) induced by tumor necrosis factor-alpha (TNF-α) in MH7A cells, a synovial cell line derived from arthritis patients, was analyzed using ELISA.

[0097] As a result, as shown in Fig. 2, it was confirmed that the expression of MMP-1 and MMP-3 substrate degrading enzymes increased by TNF-α was reduced by CGK012.
