Peptides showing anti-inflammatory activity and anti-inflammatory composition containing the same as an active ingredient {Peptides having anti-inflammatory activity and composition the same for anti-inflammatory}

The present invention relates to a peptide exhibiting anti-inflammatory activity and an anti-inflammatory composition comprising the same as an active ingredient, and more particularly, to nitrogen monoxide (NO) and tumor necrosis factor-α (TNF-α ) Has an anti-inflammatory effect that inhibits the production, has no cytotoxicity, and has very excellent bioavailability, and an anti-inflammatory pharmaceutical composition, cosmetic composition, or food composition comprising the peptide as an active ingredient.

The proportion of elderly people continues to increase due to the recent economic development and the development of medical technology and the prolongation of the average life span. Chronic inflammatory diseases such as atopy and asthma are caused by chronic inflammatory reactions due to immune system abnormalities caused by environmental pollution and increased stress. It is an increasing trend (Chang et al. , 1994, Korean J. Gastroentrol., 26:907-918.; Heinzemann and Daser, 2002, Int. Arch.Allergy Immunol. 127:170-180.; Song et al. , 1998, Korean J. Intern. Med., 55:158-168.; Sung et al. , 2012, J. Ethnopharmacol. 144:94-100.).

In general, the inflammatory response is a defense mechanism of living tissues against external stimuli such as bacterial infection or internal stimuli such as metabolites in the body, and various cytokines such as TNF-α, IL-1β, IL-6, etc. It occurs as cytokines and nitric oxide (NO) are produced. In addition, lipid polysaccharide known as endotoxin (lipopolysaccharide, LPS) is induced by the activation of the outer membrane of gram-negative bacteria present in the cells, the NF- κ B (nuclear facter- κ B ) within a transfer element cells in macrophages or monocytes It induces gene expression of inflammatory cytokines, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2), and produces inflammatory mediators.

Therefore, in order to control the inflammatory response and is a key factor in regulating the secretion of iNOS, COX-2, or expression, and cytokine and nitric oxide of NF- κ B, this modulates the activity of the factor, such materials are inflammatory diseases (Kim et al. , 2013b, J. Korean Med. Ophthalmol. Otolaryngol. Dermatol., 26:54-64.)

Substances currently used for anti-inflammatory purposes include non-steroidal flufenamic acid, ibuprofen, benzydamine, indomethacin, and the like; Steroids include prednisolone, dexamethasone, hydrocortisone, and betamethasone, but these substances are highly toxic and cause serious side effects such as liver damage, cancer, and stroke. There are restrictions. In addition, there may be a problem that causes severe immunosuppression due to inability to selectively act on substances that cause inflammation. Accordingly, the development of an inflammatory treatment using natural products that is safe for the living body and has the advantage of being easy to take for a long time compared to conventional medicines is being made, but the effective concentration showing efficacy is weak in the case of anti-inflammatory substances extracted from natural products, and is cultivated in agricultural land. Since it must be done, there is a problem such as a high production cost.

In order to improve the above problems, a new concept of anti-inflammatory drugs is being developed as an alternative to conventional chemo-inflammatory drugs or inflammatory drugs using natural products, and in particular, many studies have been conducted on the synthesis of peptides having anti-inflammatory activity having anti-inflammatory activity. Is losing.

However, the synthesized peptide has very good anti-inflammatory activity in in vitro experiments and does not exhibit cytotoxicity, but in reality, in in vivo experiments, the anti-inflammatory effect is often insignificant. This is because there are various reasons, but mainly because the physiological and anatomical conditions in vivo are very different from the experimental conditions in vitro. First, if the physiological condition of salt is present, the activity of the peptide with a low positive charge is significantly inhibited. Second, because peptides have a small molecular weight and size, they are almost absorbed by the kidneys and released into the body. Third, it is easily cut off by protein and peptide degrading enzymes (protease and peptidase) present in all tissues, cells, body fluids, and blood in a living body and loses its activity.

Accordingly, the inventors of the present invention solved the above problems and while continuing research on substances exhibiting excellent anti-inflammatory activity, developed a peptide that can be economically mass-produced using only 10 to 14 common amino acid residues, and the peptide is By confirming that it does not exhibit cytotoxicity and exhibits excellent anti-inflammatory activity, the present invention has been completed.
