Definitions
- the present invention relates to a composition for prevention or treatment of atopy accompanied by atopic, itchy or itchy skin containing N-acetyl or N-acyl amino acid as an active ingredient, or for skin moisturizing or skin-soothing.
- Itching is defined as an unpleasant sensation that causes a desire to scratch or rub the skin (Andersen HH et al., Human surrogate models of histaminergic and non-histaminergic itch, Acta Dermato-Venereologica 95 (7): 7717 (2015)), although the symptoms are common in skin and systemic diseases, their characteristics are not well known.
- Inflammatory mediators also cause itching in several inflammatory skin diseases. However, not all forms of itching are associated with mediators, mechanical or electrical stimuli, and itching caused by dry skin may appear irrelevant to mediators.
- mediators that cause itching include histamine, Serotonin, Prostaglandin E, Tachykinin, , Cytokines, proteases, opioid peptides, platelet-activating factors, and the like.
- Atopic dermatitis is an eczema-like skin lesion that occurs in people with atopic eczema.
- Endogenous eczema also known as Benny Yangjin, genetic tendency, but the cause is unknown.
- Benny Yangjin also known as Benny Yangjin
- 70-80% of pediatric eczema is atopic dermatitis.
- the present inventors have sought to find substances that can safely be prescribed without fear of itching and / or atopy due to various causes. As a result, it has been confirmed that N-acetyl or N-acyl amino acids corresponding to amino acids are highly effective for itching and / or atopy, thereby completing the present invention.
- an object of the present invention is to provide a composition for preventing, ameliorating or treating atopy.
- Another object of the present invention is to provide a composition for preventing, ameliorating or treating itch.
- composition for preventing, ameliorating or treating atopy comprising N-acetyl amino acid, N-acyl amino acid or a salt thereof as an active ingredient.
- composition for preventing, ameliorating or treating itch which comprises N-acetyl amino acid, N-acyl amino acid or a salt thereof as an active ingredient.
- compositions for preventing, ameliorating or treating atopic and pruritic diseases comprising an N-acetyl amino acid, an N-acyl amino acid or a salt thereof as an active ingredient.
- the present inventors have sought to find substances that can safely be prescribed without the fear of side effects with itching and / or atopy due to various causes.
- various kinds of N-acetyl or N-acyl amino acids are highly effective against itching and / Respectively.
- atopy " means the activity of preventing, ameliorating or treating atopic disease or atopic syndrome.
- the atopic disease Or atopic syndrome refers to a disease or syndrome caused by an allergic reaction in which the body becomes extremely sensitive without or in direct contact with allergic antigens such as atopic allergy and atopic eczema atopic eczema, atopic dermatitis, allergic conjunctivitis, allergic rhinitis, or asthma, and the like.
- the composition of the present invention the in vivo targeting induced atopic dermatitis with benzene (DNFB) 2,4-dinitro-fluoro animal models balb / c mice (in vivo) in the experiment (Example 4), significantly reduced the level of IgE (immunoglobulin E) in atopic dermatitis (Example 5), the Th2 immunomodulating cytokine associated with lesions of atopic dermatitis IL (interleukin) -4 and interferon gamma (interferon gamma) (Example 6).
- DNFB in vivo targeting induced atopic dermatitis with benzene
- " itching " or " pruritus " in the present specification is not particularly limited, and includes the following: paroxysmal itching, winter itching, anal itching, vulvar itching, scrotum itching, watery itching, scalp itching, nasal itching, Itching; Itching accompanied by an internal medical disorder such as gall bladder, chronic itching, chronic renal failure, malignant tumor, iron deficiency anemia, intrinsic erythropoiesis, hyperthyroidism, hypothyroidism, diabetes and acquired immunodeficiency; And itching which is accompanied by mental skin diseases such as chronic simple poisoning, itching rash, hairy wall, nervous scraping wounds, skin involvement, and parasitism.
- Paroxysmal itching is a seizure-prone itch, which is seen in chronic simple poisons or dermatitis.
- Anal anxiety is an uncomfortable feeling of scratching the skin around the anus, often involving psychogenic factors. It may occur regardless of age, but it occurs more often after middle age. However, the cause of all anal itching is not only psychogenic, but it can be caused by contamination and irritation around the anus. Colonic anomalies such as dentition, hemorrhoids, fistula, and chronic diarrhea, spicy foods, and medicines can further aggravate the irritation. Several infectious diseases such as Staphylococcus, Streptococcus, Fungus, Candida, and Herpes simplex virus can cause itching. Candida infections are most common, with cracks appearing at the time of infection and the epidermis appearing to be watery.
- Neurodermatitis of the anus can be scratched by the affected part until it is bleeding due to severe itching, and it can show the same findings as the chronic simple popliteal part of the other part.
- Candida infection The most common cause of vulvar itching is Candida infection. Other factors may include trichomoniasis vaginitis, contact dermatitis due to pads, birth control pills, vaginal wash liquids, condoms, and the like. After middle age, cystic atrophy is a common cause. In Fox-Fordyce disease, severe itching may also occur. However, transient itching may also be caused by friction, sweating, or vomiting during pregnancy.
- adult scrotum has immunity to fungal infections like adult scalp, but it is a site where localized chronic simple poisoning occurs well.
- the cause is often a psychogenic factor, a severe fever, and intensive treatment It may last for many years.
- Scalp itching can occur as an independent symptom without obvious lesions of the scalp, and it can be seen in middle-aged or elderly people. Itching is very severe and appears to be spasmodic, which is exacerbated by fatigue or stress.
