Description

Composition for antioxidant, wound healing, skin whitening or wrinkle improvement comprising Fructobacillus fructosus PRC-1 culture solution

[0001] The present invention relates to a composition for antioxidant, wound healing, skin whitening or wrinkle improvement, comprising Fructobacillus fructosus PRC-1 KCTC15271BP; a culture solution thereof; or an extracellular vesicle thereof.

[0002] As modern people's economic well-being improves and their participation in social life increases, interest in skin beauty and health is on the rise across all age groups. Numerous beauty-related cosmetics and foods are being developed to prevent skin aging and maintain clear, healthy skin by suppressing skin stress.

[0003] In addition, the development of compositions that have the function of suppressing the production of free radicals or active oxygen is ongoing, but due to consumers' low preference for synthetic compounds, recently developed products are made from natural materials.

[0004] Meanwhile, probiotics are live bacteria that are distributed as dominant bacteria in the human intestines, where various microorganisms exist, and promote the growth of beneficial bacteria in the body. They live symbiotically in the human digestive system, breaking down fiber and complex proteins to transform them into important nutrients. They also inhibit the growth of harmful bacteria such as Escherichia coli and Clostridium difficile, improve diarrhea and constipation, and play a role in vitamin synthesis and lowering blood cholesterol. Among these probiotics, lactic acid bacteria are bacteria that obtain energy by fermenting sugars and produce large amounts of lactic acid. They are widely distributed in nature, including agricultural products, foods, and the bodies of humans and animals. They are widely used in the fermentation of cheese, fermented milk, kimchi, and bread. In general, it is known that consuming lactic acid bacteria not only suppresses harmful bacteria among the intestinal microflora, but also increases beneficial bacteria that aid in the digestion, absorption, and breakdown of food. Therefore, it has been reported that consuming lactic acid bacteria has various benefits, including reducing blood cholesterol, boosting immunity, suppressing endogenous infections, improving liver cirrhosis, and having anticancer effects. Furthermore, recent research is also being conducted to enhance the efficacy of natural products fermented with lactic acid bacteria.

[0005] To date, approximately 400 species of lactic acid bacteria have been discovered, and they are being used in the manufacture of pharmaceuticals, health functional foods, and cosmetics. Fermented solutions obtained by culturing these lactic acid bacteria in common culture media, such as those containing skim milk, whey, and sugars, have been reported to have effects such as whitening, moisturizing, skin softening by increasing the turnover rate of the stratum corneum, and wrinkle reduction. However, in reality, these functional effects of compositions containing these fermented solutions are often due to other raw materials added to the composition rather than the active ingredients contained in the fermented solution.

[0006] Accordingly, the inventors of the present invention have completed the present invention by confirming that Fructobacillus fructosus PRC-1 KCTC15271BP isolated from honey; its culture solution; or its extracellular vesicles; has excellent antioxidant, wound healing, skin whitening, or wrinkle improvement effects.

[0007] The purpose of the present invention is to provide a pharmaceutical composition for preventing or treating wounds, skin pigmentation diseases, or skin wrinkle-related diseases, comprising Fructobacillus fructosus PRC-1 KCTC15271BP; a culture solution thereof; or an extracellular vesicle thereof.

[0008] The purpose of the present invention is to provide a food composition for antioxidant, wound healing, skin whitening or wrinkle improvement, comprising Fructobacillus fructosus PRC-1 KCTC15271BP; a culture solution thereof; or an extracellular vesicle thereof.

[0009] The purpose of the present invention is to provide a cosmetic composition comprising Fructobacillus fructosus PRC-1 KCTC15271BP; a culture solution thereof; or an extracellular vesicle thereof.

[0010] The purpose of the present invention is to provide a feed composition comprising Fructobacillus fructosus PRC-1 KCTC15271BP; a culture medium thereof; or an extracellular vesicle thereof.

[0023] Additionally, depending on the need, live cells, dead cells or cultures thereof may be used after being crushed or after further extraction.

[0024] Shredded material refers to a material that has been separated and processed into a shredded form through mechanical or chemical methods. For example, shredded material can be produced through bead mills, presses, sonicators, microfluidizers, or enzyme treatment.

[0025] The term "extract" refers to a "water (liquid)" form obtained by further extracting living cells, dead cells, and / or fragments using a commonly known extraction method. For example, it refers to a product obtained by extracting living cells, dead cells, and / or fragments using a commonly known extraction method (a known extraction solvent (e.g., water, C1 to C4 alcohol (methanol, ethanol, etc.)).

[0026] Preferably, the culture medium may be obtained by culturing the strain for 12 hours or more, and preferably, may be obtained by culturing for 12 to 30 hours, 12 to 28 hours, 12 to 26 hours, 12 to 24 hours, 18 to 30 hours, 18 to 28 hours, 18 to 26 hours, 18 to 24 hours, 24 to 30 hours, or 24 to 28 hours, and for example, may be obtained by culturing for 24 to 26 hours, but is not limited thereto.

[0031] In the present invention, "extracellular vesicles (EV)" refers to particles secreted from cells and released into the extracellular space, and are called exosomes, ectosomes, microvesicles, microparticles, exosome-like vesicles, etc. Extracellular vesicles were observed in electron microscopic studies to originate from specific intracellular compartments called multivesicular bodies (MVBs) and to be released and secreted outside of the cell, rather than being directly separated from the plasma membrane. That is, when fusion of multivesicular bodies and the plasma membrane occurs, the vesicles are released into the extracellular environment, which are called extracellular vesicles.

[0032] Extracellular vesicles (EVs) facilitate the exchange of materials (proteins, lipids, and genetic material) between cells and function as mediators for physiological and pathological signaling. Extracellular vesicles are broadly categorized into exosomes and microvesicles. Exosomes vary in size depending on their biological origin. They are intraluminal vesicles created when the endosomal membrane inwardly inflates during the maturation of multi-vesicular endosomes, and are secreted when multi-vesicular endosomes fuse with the cell surface. Microvesicles, 50-1000 nm in size, are vesicles secreted outside the cell by protruding from the plasma membrane. Each cell produces different types of EVs depending on its physiological state and secretes EVs with specific lipid / protein / nucleic acid compositions. The above “extracellular vesicles” is used to mean exosomes and microvesicles.

[0033] The above extracellular vesicles may have an average diameter of 20 nm to 400 nm, preferably 50 nm to 300 nm, more preferably 100 nm to 250 nm.

[0034] The above extracellular vesicles can be obtained using an extracellular vesicle (EV) extraction method known in the art, and are not limited thereto, but can be obtained by an extraction method including, for example, the following steps:

[0035] 1) Step of culturing Fructobacillus fructosus PRC-1;

[0036] 2) A step of recovering the above Fructobacillus fructosus PRC-1 culture solution;

[0037] 3) A step of centrifuging the recovered culture solution to remove cell residue; and

[0038] 4) A step of obtaining extracellular vesicles from the culture medium from which the cell debris has been removed using at least one selected from the group consisting of tangential flow filtration (TFF), ultracentrifugation, size exclusion chromatography, and an exosome isolation kit.

[0039] In one embodiment, the present invention can purify extracellular vesicles of Fructobacillus fructosus PRC-1 with high purity through filtration and ultracentrifugation.

[0040] In the process of isolating extracellular vesicles in the present invention, any method commonly used in the art can be used without limitation, for example, utilizing the commercially available exosome isolation kit (e.g., EXO-BB, ExoQuick ® -ULTRA, ExoQuick ® -TC, Capturem TM Exosome Isolation Kit, Total Exosome Isolation Kit, ExoTrap TM Exosome Isolation Spin Column Kit, Exo2DTM, etc.), or including separation based on the difference in specific gravity between components in a solution (e.g., centrifugation), separation based on size (e.g., ultrafiltration or vacuum filter), separation based on affinity for a specific substrate (e.g., affinity chromatography), but is not limited thereto, and any method commonly used in the art as a separation method based on the unique physical properties of a target substance in a heterogeneous sample can be used without limitation.

[0110] 2. Preparation of Fructobacillus fructosus PRC-1 culture solution

[0111] For the preparation of culture medium, live Fructobacillus fructosus PRC-1, a lactic acid bacterium isolated from honey, was added to DMEM medium (1*10 9 CFU / ml) was cultured for 24 hours, centrifuged, and the supernatant was separated. The supernatant was adjusted to pH 7.4, sterilized using a syringe filter (0.2 ㎛), and then stored.

[0112] 3. Preparation of extracellular vesicles derived from Fructobacillus fructosus PRC-1

[0113] Extracellular vesicles derived from Fructobacillus fructosus PRC-1 were isolated according to the following steps.

[0114] 1) The culture solution of Fructobacillus fructosus PRC-1 according to the above manufacturing example 1-2 was centrifuged at 2000 g for 10 minutes to separate and remove the strain from the culture solution.

[0115] 2) The culture solution centrifuged in step 1 was filtered through a 0.2㎛ bottle top filter to increase the purity of the culture solution.

[0116] 3) It was concentrated 10-fold through tangential flow filtration (TFF).

[0117] 4) The culture solution concentrated in step 3 above was filtered through a 0.22 ㎛ syringe filter.

[0118] 5) The culture solution filtered in step 4 above was centrifuged at 4°C, 150,000g for 3 hours to separate extracellular vesicles.

[0119] 6) After ultra-high-speed centrifugation in step 5 above, the supernatant was removed and the remaining extracellular vesicle pellet was resuspended in a buffer solution (PBS).

[0120] 4. Preparation of Fructobacillus fructosus PRC-1 dead cells

[0121] Fructobacillus fructosus PRC-1 KCTC15271BP was heat treated three times at 90°C for 10 minutes to produce dead cells.

[0122] 5. Preparation of Fructobacillus fructosus PRC-1 lysate (soluble and insoluble)

[0123] Fructobacillus fructosus PRC-1 (Fructobacillus fructosus PRC-1) KCTC15271BP was centrifuged and 1x10 6 Suspend in sterile distillation to CFU / mL, 4o Sonication at C (1 min treatment, 1 min rest, repeated 5 times) and centrifugation (10,000 g, 4 o C, 15 minutes) to obtain the supernatant (soluble matter) and precipitate (insoluble matter). This was freeze-dried and used.

[0124] <Example 1> Measurement of skin cell protection ability of Fructobacillus fructosus PRC-1 culture solution

[0125] 1. Cytotoxicity evaluation of Fructobacillus fructosus PRC-1 culture solution

[0126] Keratinocytes (HaCaT) were seeded in 96-well plates at 5X10 4 The cells were cultured for 16 hours in DMEM medium containing 10% (v / v) FBS at a concentration of 10 cells / ㎖. Thereafter, DMEM medium containing 1% (v / v) FBS with 2.5%, 5%, or 10% of the Fructobacillus fructosus PRC-1 culture solution according to Manufacturing Example 1-2 was treated, and DMEM medium containing 1% (v / v) FBS without the Fructobacillus fructosus PRC-1 culture solution was used as the control group.

[0127] After culturing for 24 h, 4 mg / ml MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) reagent was diluted 10-fold in DMEM medium and treated for 4 h. Afterwards, formazan crystals were dissolved using DMSO, and the absorbance was measured at 540 nm using a spectrophotometer. Cytotoxicity was expressed as a percentage based on the absorbance measured in the control group.

[0128] When cells are treated with MTT, MTT is converted into formazan crystals due to a reduction reaction in the mitochondria within the cells, and cytotoxicity can be determined through the amount of formazan crystals produced.

[0129] The results of this experiment confirmed that the Fructobacillus fructosus PRC-1 culture solution did not affect cytotoxicity (see Figure 2). Based on these results, subsequent experiments were conducted using the Fructobacillus fructosus PRC-1 culture solution at a maximum concentration of 10%.

[0130] 2. Confirmation of the keratinocyte recovery ability of Fructobacillus fructosus PRC-1 culture solution.

[0131] Keratinocytes (HaCaT) were seeded at 3X10 in a 12-well plate with 2-well silicone attached. 5 The cells were cultured for 16 hours in DMEM medium containing 10% (v / v) FBS at a concentration of 10 cells / ㎖. The medium was replaced with a medium not containing FBS, and the silicone was removed to create a cell-free gap. Thereafter, the medium was replaced with DMEM medium containing 1% (v / v) FBS supplemented with 2.5%, 5%, or 10% of the Fructobacillus fructosus PRC-1 culture medium according to Manufacturing Example 1-2. After 1 hour of culture, hydrogen peroxide was treated at a concentration of 500 μM, and the cells were imaged after 0 h, 12 h, and 24 h. In addition, the area of ​​the cell-free gap in the image was quantified using the Image J program.

[0132] This experiment aimed to determine the effect of Fructobacillus fructosus PRC-1 culture on the migratory ability of keratinocytes, which are essential for wound healing and regeneration. First, when keratinocytes were stressed by treating them with hydrogen peroxide, it was confirmed that the migratory ability of the cells was reduced and the cell-free gap was maintained. However, when treated with Fructobacillus fructosus PRC-1 culture, the cell migratory ability increased despite the stress caused by hydrogen peroxide treatment, and it was confirmed that the cell-free gap disappeared at all concentrations after 24 h of treatment (see Figures 3A and 3B).

[0133] That is, it was confirmed that Fructobacillus fructosus PRC-1 culture solution increases the migratory ability of keratinocytes and contributes to wound healing and regeneration.

[0134] <Example 2> Measurement of the ability of Fructobacillus fructosus PRC-1 culture solution to inhibit intracellular ROS production

[0135] 1. ROS measurement (DCF-DA assay) method

[0136] Keratinocytes (HaCaT) were seeded in 12-well plates at 5X10 4 Cells were cultured in DMEM medium containing 10% (v / v) FBS at a concentration of 10 cells / ㎖ for 16 hours, and then treated with DMEM medium containing 1% (v / v) FBS supplemented with 2.5%, 5%, or 10% Fructobacillus fructosus PRC-1 culture. After 1 hour, hydrogen peroxide was treated at a concentration of 500 μM and cultured for 3 hours. Afterwards, the cells were stained with 10 μM DCF-DA for 20 minutes, and the generated ROS were imaged using a fluorescence microscope. In addition, the relative level of the generated ROS was quantified using the Image J program.

[0137] 2. Evaluation of the ability of Fructobacillus fructosus PRC-1 culture solution to inhibit intracellular ROS production

[0138] DCF-DA, a non-fluorescent substance, is oxidized by ROS to the fluorescent DCF. Using this principle, the DCF-DA assay was used to confirm the inhibitory ability of Fructobacillus fructosus PRC-1 culture to inhibit intracellular ROS production.

[0139] In an experiment where Fructobacillus fructosus PRC-1 culture was treated together with hydrogen peroxide, it was confirmed that Fructobacillus fructosus PRC-1 culture inhibited ROS production as fluorescence was not observed (see Figures 4A and 4B). In particular, compared to the hydrogen peroxide control group which showed strong fluorescence, it was confirmed that the Fructobacillus fructosus PRC-1 culture strongly inhibited ROS production starting from the low concentration treatment of 2.5%.

[0140] <Example 3> Evaluation of the whitening improvement efficacy of Fructobacillus fructosus PRC-1 culture solution

[0141] 1. Method for measuring the inhibition rate of melanin biosynthesis

[0142] B16F10 cell line, a human-derived malignant melanoma cell line, was purchased from ATCC and used in the experiment. B16F10 cells were cultured and 1X10 cells were seeded per well in a 12-well plate. 5 After dispensing at cells / ml, the cells were cultured for 24 hours for attachment and stabilization. After the culture was completed, DMEM medium containing 1% (v / v) FBS supplemented with 2.5%, 5%, or 10% Fructobacillus fructosus PRC-1 culture medium or 2% Arbutin, known as a whitening agent, was treated for 1 hour. Afterwards, α-melanocyte-stimulating hormone (α-MSH), a melanin-stimulating hormone, was treated, and the melanin production concentration was expressed as a percentage compared to the control group. After 48 hours, each well was washed with PBS, 500 ㎕ of 1 N NaOH solution was added, and the cells were dissolved at 60°C for 3 hours. The absorbance was measured at 475 nm using a microplate reader.

[0143] 2. Evaluation of the inhibition rate of melanin biosynthesis by lactic acid bacteria culture solution

[0144] Excessive melanin synthesis and accumulation on the skin surface leads to hyperpigmentation symptoms such as freckles and melasma. Experimental results showed that α-MSH treatment in B16F10 cells induced melanin production by 193.6%, while treatment with 2% arbutin, the positive control, inhibited melanin production by 115.8%.

[0145] Meanwhile, Fructobacillus fructosus PRC-1 culture inhibited melanin production in a concentration-dependent manner. In particular, treatment with 10% Fructobacillus fructosus PRC-1 culture inhibited melanin production by up to 70%, resulting in a decrease in melanin production compared to the control group not exposed to α-MSH. (See Fig. 5).

[0146] <Example 4> Evaluation of the wrinkle improvement efficacy of Fructobacillus fructosus PRC-1 culture solution

[0147] 1. Method for measuring elastase inhibition

[0148] 30 μL of the test substance was added to 170 μL of 0.2 M Tris-HCl buffer (pH 8.0), and 50 μL of porcine pancreas elastase diluted to 0.5 units / mg was added, and then left at room temperature for 10 minutes. The test substance was 2.5%, 5%, or 10% Fructobacillus fructosus PRC-1 culture medium, or DMEM medium containing 1% (v / v) FBS supplemented with 2 mg / mL of vitamin C as a positive control. Afterwards, 50 μL of N-succinyl-(L-Ala)3-p-nitroanilide, a substrate, was diluted to 2 mg / mL and added, and the amount of p-nitroanilide produced was measured using a microplate reader at a wavelength of 410 nm. The elastase activity inhibition ability was calculated using the following equation 1.

[0149] [Formula 1]

[0150] Elastase inhibition (%) = (Control absorbance - Experimental absorbance) / Control absorbance * 100

[0151] 2. Evaluation of the Elastase Activity Inhibition Ability of Fructobacillus fructosus PRC-1 Culture Solution

[0152] Elastase, an elastin-degrading enzyme known to be the cause of wrinkles, reacts with its substrate, N-succinyl-(L-Ala)3-p-nitroanilide, to produce p-nitroanilide. In this experiment, the elastase activity inhibitory ability of Fructobacillus fructosus PRC-1 culture was evaluated through changes in the amount of p-nitroanilide produced.

[0153] As a result, it was confirmed that the positive control group treated with Vitamin C inhibited the activity of Elastase by approximately 95%. In the case of Fructobacillus fructosus PRC-1 culture, the higher the concentration, the higher the inhibition effect of Elastase activity, and in particular, it was confirmed that the group treated with 10% of Fructobacillus fructosus PRC-1 culture showed inhibition of up to 85% (see Figure 6).

[0154] <Example 5> Evaluation of the whitening improvement efficacy of extracellular vesicles derived from Fructobacillus fructosus PRC-1

[0155] 1. Evaluation of the inhibition rate of melanin biosynthesis by extracellular vesicles derived from Fructobacillus fructosus PRC-1

[0156] The inhibition rate of melanin biosynthesis of extracellular vesicles derived from Fructobacillus fructosus PRC-1 was measured in the same manner as in Example 3-1 above, but 0.5x10 of extracellular vesicles derived from Fructobacillus fructosus PRC-1 was used instead of the Fructobacillus fructosus PRC-1 culture medium. 8 particles / ml, 5x10 8 particles / ml or 50x10 8 particles / ml were used.

[0157] As a result of the experiment, it was confirmed that melanin production was induced by 219.1% by α-MSH treatment in B16F10 cells, and melanin production was inhibited by 142.5% by treatment with 2% Arbutin as a positive control.

[0158] Meanwhile, extracellular vesicles derived from Fructobacillus fructosus PRC-1 inhibited melanin production in a concentration-dependent manner. In particular, 50x10 extracellular vesicles 8 When treated with particles / ml, melanin production was inhibited by up to 125.2%, confirming that melanin production was inhibited more strongly than the positive control group (see Figure 7).

[0159] Through the above results, it was confirmed that Fructobacillus fructosus PRC-1, its culture solution, or its extracellular vesicles according to the present invention have excellent efficacy in inhibiting reactive oxygen species (ROS) production, inhibiting melanin production, promoting wound healing and regeneration, and inhibiting elastase activity, and thus it is expected to have high utility as a cosmetic, pharmaceutical, and food agent.
