More particularly, the present invention relates to a composition containing suberic acid or a salt thereof as an active ingredient, The present invention relates to a composition for improving skin moisturization, skin exfoliation, skin elasticity enhancement, erythema suppression, skin wrinkle enhancement, and / or skin photo-aging improvement effect using suberic acid or a salt thereof suppressing degradation, erythema suppression, A cosmetic composition, a health functional food composition, a medicine, and a quasi-drug composition.

Recent advances in medical technology have led to increased interest in skin care and health as life expectancy has been extended and quality of life has been improved and the desire for a healthy and beautiful life has increased. Various cosmetic functional cosmetics have been developed for the purpose of maintaining a healthy skin, and researches for prevention of skin wrinkle formation, mitigation and improvement have been actively carried out. In addition, recently, cosmetic ingredients reach skin dermis and there is a limitation in supplying nutrients. As a result of the change in perception that ingestion of nutrients or functional ingredients to the skin can provide a skin cosmetic enhancement effect, JNutr, 132, 3090-3097 (2002), Tanno, O. et al., ≪ RTI ID = 0.0 > al., ≪ / RTI & , Nicotinamide increases biosynthesis of ceramides as well as other stratum corneum lipids to improve the epidermal permeability barrier (Br J Derm, 143, 524-531, 2000).

The skin consists largely of epidermis, dermis and hypodermis. The outer layer of the epidermis, especially the outer layer of the epidermis, plays a role as a skin barrier, thereby causing loss of water and electrolytes from the skin While the dermis, through the synthesis of collagen and elastin, maintains the elasticity of the skin and supports the structure. In other words, collagen and elastin are the main proteins produced in fibroblasts, which are involved in the mechanical durability of the skin, the binding force and the resilience of tissues (Moskowit, RW et al, Role of collagen hydrolysate in bone and joint disease, Semin Arthritis Rheu, 87, 2000). Collagen constitutes various isoforms according to its morphological and structural characteristics. There are 28 types of collagen isotypes in human tissues. Collagen existing in skin tissues is classified into types 1 and 3. 4. 6. 7. 13, 14, 17, etc. are known. Collagen type 1 and 3 form the intercellular component of the dermis, while collagen type 7 is the main component of the dermal and epidermal junction (Pei, M. et al., Expression of collagen type I, II and III in the loose body of osteoarthritis, J. Orthop. Sci., 5: 288, 2000).

In skin connective tissue, type I collagen is the most abundant of extracellular matrix proteins, and other proteins such as elastin, fibronectin, integrin, fibrillin, and proteoglycan exist. The newly synthesized procollagen is secreted into the extracellular space of the skin cells through an enzymatic reaction and forms a microfibril of a triple helix configuration, while microfibrils form leucine-rich small proteoglycans -rich small proteoglycans) to form a fibril. As a result, these fibrils are gathered to form collagen fibers that provide skin's binding force and elasticity (Bateman, J. F. et al., Collagen superfamily. Extracellular matrix, Harwood, New York, 2, 22-26, 1996).

Skin aging is known to be caused by a decrease in collagen content, which is the protein that occupies most of the collagen in skin dermal tissue. Since collagen gives skin tension and strength, collagen reduction has a very deep relationship with skin aging and wrinkle formation have. Skin aging is largely divided into endogenous aging by physiological aging and photoaging caused by continuous exposure to ultraviolet radiation (UV). Repeated exposure to ultraviolet light results in increased collagenase and denaturation and destruction of collagen fibers, reducing skin elasticity and promoting the production of wrinkles. In other words, the development of reactive oxygen species (ROS) is increased in skin tissue exposed to ultraviolet rays continuously, and the latter is a signal transduction system mediated by growth factor receptor (EGF-R), tumor necrosis factor (TNF) (Sachsenmaier, C. et al., Involvement of growth factor receptors in the mammalian UVC response. Cell, 78: 963-972, 1994; Dy, LC et al., Augmentation of ultraviolet B radiation-induced tumor necrosis factor production by the epidermal platelet-activating factor receptor. J. Biol. Chem .: 274, 26917-2692, 1999). Activation of these receptors results in continuous phosphorylation, which activates proteins that mediate downstream signaling, including mitogen-activated protein kinase (MAPK), resulting in activator protein-1 (AP-1 ) And nuclear factor κB (NF-κB) to induce inflammatory responses and promote the activity of collagenases such as matrix metalloproteinases (MMPs), thereby reducing skin elasticity and promoting wrinkle formation (Kang, S. et al., Inflammation and extracellular matrix degradation mediated by activated transcription factor nuclear factor-kB and activator protein-1 in Inflammatory acne lesions in vivo. Am J. Pathol., 166: 1691-1699, 2005) . AP-1 regulates the expression of a number of genes involved in cell growth and differentiation and strongly regulates the expression of some MMPs. Among MMPs whose expression is regulated by AP-1, MMP-1 is known as collagenase 1, and type 1 and 3 collagen are substrates.

On the other hand, suberic acid is mainly used for industrial manufacturing, and is used, for example, as a lubricant for a plastic lubricant, as a hydraulic fluid for a hydraulic machine, or for producing a candle (Chemical Engineering Dictionary, engineering dictionary, Seoul: Hyeon Mun, 1995). There is no physiologically active function of suveric acid reported in the past, and metabolomic studies have been mainly performed. In patients with ketosis, there is a report that suberic acid is detected as metabolites in urine and is used as an index of patients with ketosis (Pettersen et al., Clinical Practice 38 : 17-24, 1972), and it has also been reported to be detected at high concentrations in patients with diabetes (Yoshioka et al., Measures of urinary adipic acid and suberic acid using high-performance liquid chromatography J Chromatogr Biomed Appl 655: 189-93, 1994). However, there has been no report on the physiological activity of subvertic acid in relation to skin health.

Effect of suberic acid on skin wrinkles using human skin fibroblasts

1-1. Experimental Method

1) Cell culture

Human dermal fibroblast (nor mal, human, neonatal, ATCC No. PCS-201-010) was purchased from ATCC (Manassas, VA, USA). The cells were cultured in 37, 5% CO ₂ incubator using fibroblast growth medium (Promo Cell, Heidelberg).

2) Procollagen Type I C-peptide (PIP) concentration measurement

To investigate the collagen biosynthesis performance, human fibroblasts were subcultured at a density of 1.0 × 10 ⁶ cells / well in a 12-well plate at concentrations of 100 μM suveric acid and vitamin C, respectively, and CO ₂ Lt; / RTI > After removing the media from each well, the plate was washed once with PBS, and 1 ml of PBS was added thereto. Ultraviolet B (UVB) was then irradiated at 20 mJ / cm ² . PBS was re-cultured for 24 hours, and the amount of procollagen secreted into the medium was measured using procollagen type C-peptide EIA kit (Takara Bio, Japan). The standard solution contained in the collagen measurement kit was diluted by concentration, absorbance was measured at 450 nm to prepare a standard concentration curve and the amount of collagen production was calculated.

1-2. Experiment result

1) Changes in the amount of procollagen secreted

Collagen, the main protein that makes up the skin, is synthesized in the form of procollagen in fibroblasts in the skin dermis and then secreted into the extracellular matrix. Procollagen secreted into the extracellular matrix is broken down by the procollagen peptidase present on the cell surface and is formed into active collagen. Therefore, the active collagen content can be measured by measuring the C-peptide content. Each value in Figure 1 represents means SEM of three measurements from three independent wells. The mean value of the other alphabets is statistically significant (p <0.05). The amount of procollagen type I C-peptide (PIP) secreted into the extracellular matrix of the human skin fibroblasts by treatment with ultraviolet light was measured in the control cells (+ UVB) irradiated with ultraviolet light. (UVB) compared to UV-irradiated control cells (SA), the amount of collagen was 23% higher than that of UV-irradiated cells (SAV). On the other hand, the amount of collagen in the cells treated with vitamin C (VitC + SA) was significantly increased by 49% as compared with the ultraviolet irradiated control cells (+ UVB), indicating that vitamin C (+ 27% (+ 23%) compared to the amount of collagen observed in cells treated alone (Figure 1). These results, when applied to the call informal formula, confirm that synergy is exhibited when suveric acid and vitamin C are treated together. Thus, suveric acid increases the amount of activated collagen in human dermal fibroblasts, and this effect of collagen increase is more effective when used with vitamin C.

2-2. Experiment result

1) Weight and dietary intake of reckless mice

UV irradiation, suberic acid and vitamin C intake did not significantly affect body weight and dietary intake of reared mice (FIG. 2). The values in Figure 2 are the mean ± SEM of 5 mice.

2) Changes in water content, elasticity and erythema index of ultraviolet irradiated mouse skin

In the + UVB control group irradiated with ultraviolet light for 10 weeks, the water content and elasticity of the skin tissue were significantly decreased while the moisture evaporation and erythema index were significantly increased compared with the normal UV group (-UVB) 3). In the case of saponin-supplemented group (SA), moisture content and elasticity were significantly increased by 88% and 53%, respectively, compared to the + UVB control group, while the moisture evaporation and erythema indexes 52% and 35%, respectively (Fig. 3). The values in FIG. 3 are the mean ± SEM of 5 mice, and the alphabet on the bar represents a significant difference by one-way ANOVA followed by Duncan's multiple range test (p <0.05).

3) Changes in skin wrinkle formation in ultraviolet irradiated mice

To evaluate the effect of suberosal intake on the degree of skin wrinkle formation, the back skin area of the experimental animals was photographed. The + UVB control group, which was exposed to UVB for 10 weeks, was able to visually observe the formation of fine wrinkles with many coarse and deep wrinkles compared to the normal UV group (-UVB) The skin thickness and the depth of the wrinkles were remarkably reduced compared to the UVB control group (Fig. 4), which was similar to the skin condition observed in the UV-unexposed UVB group.

As a result of the measurement of the degree of wrinkle formation, the + UVB control group was thicker and deeper than the non-UV irradiated normal group (-UVB) It was observed that the wrinkles and fine wrinkles were formed. In the supubolic acid group, the thickness and depth of the wrinkles were remarkably improved as compared with the + UVB control group, even though the same UV intensity was irradiated. (Fig. 5A). As a result of numerical analysis of the degree of wrinkle formation on the simulated plate using a computerized image analyzer, the total wrinkle area of the SA group was 48%, the maximum wrinkle depth was 32%, the average wrinkle depth was 28% The length was significantly reduced by 56%, and the wrinkle-reducing effect of such suberic acid was similar to the wrinkle-reducing effect observed in vitamin C (FIG. 5B). Values in FIG. 5B are mean ± SEM of 5 mice, and the alphabet on the bar represents a significant difference by one-way ANOVA followed by Duncan's multiple range test (p <0.05). Therefore, it can be seen that the ingestion of suberic acid has an effect of remarkably suppressing the generation of wrinkles by ultraviolet irradiation.

4) Changes in skin thickness of ultraviolet irradiated mice

As the photoaging by ultraviolet rays proceeds, the formation of the stratum corneum is increased to thicken the skin to protect the skin dermis layer, and thus the thickness of the skin skin layer is increased by ultraviolet irradiation, which means that skin damage due to photoaging is large J Molecular mechanism of skin aging Mech Ageing Dev 123: 801-810, 2002)

The thickness of the back skin was measured using a digital micro caliper on the last day of the experiment. As a result, the skin thickness was significantly increased in the + UVB control group compared to the non-UV irradiated normal group (-UVB) Was significantly reduced in the skin thickness by 24% as compared to the + UVB control group (Fig. 6A). The values in FIG. 6A are the mean ± SEM of 5 mice and the alphabets on the bar represent significant differences by one-way ANOVA followed by Duncan's multiple range test (p < 0.05).

The skin surface layer thickness of uninhabited mouse was observed by H & E staining of skin tissue, and the + UVB control group showed thickening of the skin epidermal layer compared to the normal group without UV irradiation (-UVB) (Fig. 6B). As shown in Fig.

5) Quantity and morphology of collagen fibers in dermal layer of ultraviolet irradiated mice

In the case of skin that has undergone photoaging by ultraviolet irradiation, the collagen fiber network of the epidermal-dermal binding site is damaged, and therefore the amount and shape of the collagen fiber is used as a skin photoaging index (Varani et al., "Inhibition of type I procollagen synthesis damaged collagen in photoaged skin and collagenase-degraded collagen in vitro. "The American Journal of pathology 158: 931-942, 2001). Ultrastructural examination of collagen fibers stained with Masson's trichrome showed that the anionic blue-colored collagen fibers were observed in the dermal layer under the epidermis of the UVB group, but UVB In the UVB group were weakly stained with aniline blue. The density of collagen fibers was relatively dense and arranged in the dermis of the dermis of the supernatant group, which was supplemented with UVB for 10 weeks, and the degree of staining by aniline blue was stronger than that of the control group. (Fig. 7).

6) Changes in gene expression in ultraviolet irradiated mouse skin

Collagen type 1 and 3 are proteins that constitute the epidermal component of the dermal layer. In particular, type 1 collagen is present in the largest amount among the extracellular matrix proteins present in the connective tissue of the skin. Meanwhile, 23 types of MMPs catalyzing collagen degradation exist in mammals. MMP types 1, 3 and 9 are known to increase by ultraviolet rays. These three types of MMPs are enzymes that degrade collagen type 1 and 3 to be. It is known that MMP-1 cleaves the middle of collagen fibers while MMP-3 and MMP-9 cleave the cut collagen fibers (Quan T. et al., Elevated matrix metalloproteinases and collagen fragmentation J Dermatological Science 23: S30-S36, 2000). In this study, we have investigated the effects of various types of cytokines in human dermal fibroblast.

As a result of RT-PCR analysis of gene expression in skin tissues, it was found that the + UVB control group had higher collagen type 1α1 and α2, and collagen type 3α1 (compared to -UVB) Expression of MMP-1a and -1b, MMP-3, and MMP-9 gene were significantly increased. On the other hand, the expression of collagen type 1α1 and α2, and collagen type 3α1 was significantly increased in the supernatant group compared to the + UVB control group, and the expression of MMP-1a and -1b, MMP-3 and MMP- (Fig. 8). Therefore, it is considered that suveric acid suppresses the formation of wrinkles due to ultraviolet irradiation by increasing collagen protein synthesis in skin tissue and inhibiting degradation of collagen fiber.

These results suggest that suberosan has the effect of preventing or alleviating skin wrinkles caused by ultraviolet rays, suggesting that it can be usefully used as functional cosmetics, health functional foods, medicines or quasi-drugs.

In addition, as compared with the nutritional cream formulation of Comparative Example 1, the relative skin wrinkle-reducing effect of the nutritional cream formulation of Experimental Example 1 containing suberic acid was 4.25, which indicates that the degree of wrinkle improvement was also excellent.

Accordingly, the cosmetic composition containing the suberic acid or the cosmetically acceptable salt thereof of the present invention as an active ingredient has no skin side effects, has an excellent effect of improving skin wrinkles, increasing the synthesis of collagen proteins and inhibiting the decomposition of collagen fibers It is excellent for improving skin wrinkles.

3-3. skin Moisture power  Increased measurement test

In order to measure the moisture holding ability of the skin when the nutritional cream of Experimental Example 1 and Comparative Example 1 shown in Table 3 were respectively applied to the skin, 20 women in the 20s to 50s of age group were observed on the left side of Table 3 Experimental Example 1 A nutritive cream (test group) was applied to the right side of the face and a nutritive cream (control group) of Comparative Example 1 of Table 3 was gently massaged in a sufficient amount. Massage was carried out evenly over a minute.

Skin moisture content was measured by using a coneometer in a constant temperature and humidity room at room temperature 25 and relative humidity 45% before application. The skin moisture content was measured in Experimental Example 1 and Comparative Example 1 of Table 3 on the left and right sides of the face, respectively After resting for 10 minutes after application, skin moisture was measured 12 hours after application and 24 hours after application. The moisture content of the skin was measured using a coneometer (CM820, Courage Khazaka electronic GmbH, Germany) which measures the moisture content of the skin by measuring the skin's electric capacity according to the moisture content of the skin. The coneometer measures the amount of moisture present in the epidermis of the skin by measuring the degree of ion of water using a sensor and numerically expressing the amount of water to calculate the amount of moisture, and the measurement method is as follows.

1) A coneometer probe was placed on the skin area to be measured.

2) When the probe is pressed onto the skin, the electrical conductivity of the skin is quantified through the sensor and displayed on the screen.

3) Measurement was repeated with different measurement sites.

4) After the measurement, the sensor was wiped with a tissue paper such as a kim wipe and then measured again.

The measured values are shown in Table 5 as average values.
