The present invention relates to a composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, and more specifically, as an extract derived from Centipeda minima, a composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, comprising Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C as active ingredients.
Autoimmune diseases, which are diseases caused by immune cells attacking organs or tissues of their own body, are incurred by immune imbalance or loss of resistance to autoantigens. Autoimmune diseases cause damage to cells or tissues by humoral immunity, cellular immunity, or both. Such an inappropriate response to autoantigens of the immune system is referred to as autoimmunity. Autoimmune diseases are associated with numerous molecules, cells, and tissues targeted by autoimmune responses, and may be systemic or specific to a certain organ depending on the distribution of the target antigens. For example, systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and multiple sclerosis (MS) are systemic autoimmune diseases. In addition, alopecia areata is an autoimmune disease that shows uneven hair loss, regardless of gender, age, and hair color worldwide, and alopecia areata exhibits a prevalence of about 0.1 to 0.2% worldwide.
Tofacitinib is widely used as an immunosuppressant for autoimmune diseases.
Tofacitinib, {3-((3R,4R)-4-methyl-3-(methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)piperidin-1-yl)-3-oxopropanenitrile}, is a compound represented by the formula shown below. The tofacitinib was first disclosed in WO 2001/042246.
Tofacitinib is a synthetic JAK (janus kinase) inhibitor, and janus kinase (JAK) is one of the enzymes that catalyze the transfer of a phosphate group. Cytokine, a protein secreted by immune cells, binds to a cytokine receptor and transmits a signal into a cell. Cytokine receptors bind to janus kinases such as TYK2, JAK1, JAK2, and JAK3.
When a cytokine binds to a cytokine receptor, phosphorylation occurs in JAK, the signal transducer and activator of transcription (STAT) is activated, and then signaling occurs, leading to hematopoietic action, inflammatory response, and immune response. In an autoimmune disease in which a hyperimmune response occurs due to cytokine overproduction, a JAK inhibitor inhibits the kinase of the cytokine receptor to which the cytokine binds.
However, not only tofacitinib but also JAKI and JAK inhibitors of the same class are synthetic drugs of which safety may not be guaranteed due to the numerous side effects identified from their raw materials. In addition, developed as prescription drugs, they have low patient accessibility, and their use is limited to pharmaceuticals for oral administration. Furthermore, their long-term use causes serious infections (nasopharyngitis, gastroenteritis, upper respiratory tract infection) and intestinal perforation due to immunosuppression, and elevated cholesterol, headache, rash, herpes zoster, anemia, and the like are caused. Moreover, based on the daily prescription of 10 mg/day, tofacitinib causes a high cost of about 6 million KRW per month when domestic health insurance does not apply.
Fatty liver is caused by the accumulation of excessive fat, mainly triglycerides, in the liver. In general, fat accumulation of more than 5% of the liver's weight is diagnosed as fatty liver. Fatty liver can be divided into alcoholic fatty liver and non-alcoholic fatty liver (NASH), which is caused in association with obesity, diabetes, and hyperlipidemia. Non-alcoholic fatty liver is associated with metabolic syndrome such as obesity, adult-onset diabetes, and hyperlipidemia. When excessive caloric intake continues, fat is accumulated in the adipocytes and the liver of the body, and various substances (cytokines) are secreted from the increased fat to cause fatty hepatitis and cirrhosis. In addition, drugs such as steroids, anti-inflammatory drugs, and heart drugs or some herbal medicines or several folk remedies can also cause fatty liver.
Centipeda minima is an annual plant belonging to the Asteraceae family. In China, the plant is used in folk remedies to treat chronic rhinitis as well as nose diseases, eye diseases, and headache. In addition, when the leaves and stems are rubbed and placed in the nostrils and kept overnight, they are effective against chronic malaria. In India, the plant is used for eye diseases, nose diseases, and toothache. The plant is distributed in Korea, Japan, China, India, Australia, eastern Siberia, and North America. The efficacy of Centipeda minima as a raw material on inflammatory disease and autoimmune diseases, and non-alcoholic fatty liver disease is not known, and so research is required.
Natural active ingredients are extracted and
selected from natural raw materials. As a general extraction method, when the raw material is a solid, a solid-liquid extraction method is used, when the raw material is a liquid, a liquid-liquid extraction (LLE) method is used. Liquid-liquid extraction is the separation of certain components of a mixture from other components by the action of a solvent on a liquid mixture containing a solute.
In general, a liquid-liquid extraction method is used. During liquid-liquid extraction, non-polar solvents such as hexane, chloroform (methane dichloride), and ethyl acetate are highly toxic. The method has problems that the extraction process is highly inefficient, complicated, and long because of the several repeated extraction processes and the drying process for removing non-polar solvents, and the production cost is high due to the low extraction efficiency and long process.
For example, in the process for extracting Brevilin A from Centipeda minima, the raw material is extracted with methanol multiple times; the resulting extracted liquid is mixed with hexane and fractionated multiple times; the resulting fraction is mixed with chloroform and fractionated multiple times; the resulting fraction is mixed with ethyl acetate and fractionated multiple times; and the resulting fraction is mixed with butyl alcohol and fractionated multiple times. Since about 25 mg of Brevilin A is extracted from 300 g of dry weight of Centipeda minima, the extraction amount is extremely little and the efficiency is very low (Non-Patent Document 1).
Therefore, an optimal extraction method capable of maximizing the extraction amount of the active ingredient of a tiny amount is required. The active ingredient can be extracted by the extraction method of Korean Patent Publication No. 10-2020-0085024, which is an application of the present applicant.
Therefore, while studying a composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, the present inventors found that a composition extracted by the optimal extraction method, as an extraction of Centipeda minima, comprising Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C as active ingredients, is effective on inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease with few side effects.

A composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease according to an Example of the present invention comprises a Centipeda minima extract.
Here, the autoimmune disease is a disease caused by an abnormal immune response due to autoimmune, but is not limited thereto, and may be, for example, hair loss, alopecia areata, rheumatoid arthritis, psoriasis, atopy, eczema, seborrheic dermatitis, scleroderma, skin immune hypersensitivity, multiple sclerosis, lupus, Behcet's disease, ankylosing spondylitis, Sjogren's syndrome, Crohn's disease, and inflammatory bowel disease.
The extract Centipeda minima extract comprises at least one selected from the group consisting of Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C as an active ingredient.
Brevilin A is represented by the formula below.
Brevilin A, having CAS number 16503-32-5, a molecular formula of C20H26O5, and a molecular weight of 346.42, is derived from Arnica sp., Centipeda sp., and Helenium sp.
A number of documents indicating that Brevilin A is contained in Centipeda minima (also referred to as ‘Abulsikcho’) have been found, and some documents reported that Brevilin A is also contained in Litsea glutinous. In addition, documents indicating that a certain amount of Brevilin A is contained in plants of the Arnica genus (Arnica longifolia, Arctium lappa, Arnica chamissonis subsp. Foliosa, and Arnica chamissonis Less.) and plants of the Helenium genus (Helenium autumnale L, Helenium alternifolium, Helenium pinnatifidum, Helenium vernale, Helenium brevifolium, and Helenium flexuosum) have been found.

Microhelenin C, having CAS number 63569-07-3, a molecular formula of C20H26O5, and a molecular weight is 346.4, is derived from Centipeda sp. and Helenium sp.
A composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease according to an Example of the present invention comprises a Centipeda minima extract, wherein the Centipeda minima extract comprises at least one of Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C, for example, comprising each of Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C alone, or comprising a combination of Brevilin A and Arnicolide D, a combination of Brevilin A and Arnicolide C, a combination of Brevilin A and Microhelenin C, a combination of Arnicolide D and Arnicolide C, a combination of Arnicolide D and Microhelenin C, a combination of Arnicolide C and Microhelenin C, a combination of Brevilin A, Arnicolide D, and Arnicolide C, a combination of Brevilin A, Arnicolide D, and Microhelenin C, a combination of Arnicolide D, Arnicolide C, and Microhelenin C, or a combination of Brevilin A, Arnicolide D, Arnicolide C, and Microhelenin C.
The action mechanism of each of the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C is described below.
The Brevilin A inhibits or suppresses the JAK-STAT signaling pathway.
The Brevilin A, which is a natural substance, is widely known to inhibit janus kinase activity (JAK) and suppresses STAT3 signaling in cancer cells (PLoS One 8 (5) (2013) e63697).
The Arnicolide D, the Arnicolide C, and the Microhelenin C inhibit or suppress cytokine-cytokine receptor interaction, mitogen-activated protein kinase (MAPK) signaling pathway, and phosphatidylinositol-3-kinase (PI3K)-AKT signaling pathway (Hair Growth Effect of Emulsion Extracted Brevilin A, a JAK3 Inhibitor, from Centipeda minima, Processes 2020, 8, 767; doi :10.33904pr8070767).
The most ideal drug candidates for NASH should reduce hepatic inflammation and hepatocellular damage, correct insulin resistance, and at the same time, have antifibrotic effects. Failure to simultaneously control these various targets can cause problems such as fibrosis. The composition is one of the ideal drug candidates that can correct insulin resistance and suppress adipocyte differentiation and fibrosis without liver damage, and provides a composition for preventing and treating fatty liver and non-alcoholic fatty liver disease. (Current efforts and trends in the treatment of NASH, Journal of Hepatology 2015 vol. 62 j S65-S75).
The Centipeda minima extract activates the WNT signaling pathway (WNT/β-catenin pathway) and facilitates the differentiation and proliferation of hair follicle stem cells and cells involved in hair growth (primary hair cells), and thus is effective for hair loss and alopecia areata among autoimmune diseases. The Centipeda minima extract increases the expression of WNT receptors and activates the WNT signaling pathway to enhance GSK3P phosphorylation and β-catenin accumulation, and activates extracellular signal-regulated kinase (ERK) (phosphorylation) to enhance the expression of growth factors such as VEGF and IGF-1 (Hair Growth Stimulation Effect of Centipeda minima Extract: Identification of Active Compounds and Anagen-Activating Signaling Pathways, Biomolecules 2021, 11, 976. https://doi.org/10.3390/biom11070976).
In addition, based on the powerful anti-inflammatory effect, the Centipeda minima has an effect of suppressing adipocyte differentiation, suppressing hepatic fibrosis in hepatic stellate cells (LX-2) (anti-fibrosis), suppressing insulin resistance, and preventing obesity.
The content of the Brevilin A may be more than double the total content of the Arnicolide D, the Arnicolide C, and the Microhelenin C.
The Brevilin A is the most important ingredient for inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, for example, hair growth and hair loss, and anti-inflammation, and the content of Brevilin A is preferably more than the total content of the Arnicolide D, the Arnicolide C, and the Microhelenin C, which are other derivatives. The may ingredient of the non-polar natural substances of Centipeda minima, which is the raw material, is the Brevilin A.
The Brevilin A is most involved in JAK-STAT signaling process, which is the main action mechanism of inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease. When Brevilin A functions with its other derivatives, the Arnicolide D, the Arnicolide, C and the Microhelenin C, a synergic effect is caused on inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease to provide a better effect on inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, for example, hair loss prevention and anti-inflammation, than in the case where each ingredient is contained alone.
For example, the Centipeda minima extract contains 30 to 90% by weight of the Brevilin A, 0 to 30% by weight of the Arnicolide D, 0 to 30% by weight of the Arnicolide C, and 0 to 15% by weight of the Microhelenin C.
The Brevilin A is included in an amount of 30 to 90% by weight, and when the amount is less than 30% or more than 90% by weight, the ingredient that is most related to the JAK-STAT signaling process becomes small and so the anti-inflammatory effect is lowered and the synergic actions with other ingredients are reduced, resulting in difficulties in sufficiently preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease.
The Arnicolide D is included in an amount of 0 to 30% by weight, and when the amount is more than 30% by weight, the synergic actions with other ingredients, which are Brevilin A, Arnicolide C, and Microhelenin C, are reduced, resulting in difficulties in sufficiently preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease. Preferably, the Arnicolide D is included in an amount of 15 to 30% by weight.
The Arnicolide C is included in an amount of 0 to 30% by weight, and when the amount is more than 30% by weight, the synergic actions with other ingredients, which are Brevilin A, Arnicolide D, and Microhelenin C, are reduced, resulting in difficulties in sufficiently preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease. Preferably, the Arnicolide D is included in an amount of 4 to 30% by weight.
The Microhelenin C is included in an amount of 0 to 15% by weight, and when the amount is more than 15% by weight, the synergic actions with other ingredients, which are Brevilin A, Arnicolide D, and Arnicolide C, are reduced, resulting in difficulties in sufficiently preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease. Preferably, the Microhelenin C is included in an amount of 3 to 15% by weight.
Therefore, when the content of each of the ingredients of the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C is out of the range, an anti-inflammatory efficacy may not be achieved.
According to one Example of the present
invention, provided is a composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, wherein the Centipeda minima extract is extracted by an extraction method comprising: preparing a primary extraction by extracting a Centipeda minima raw material; performing secondary extraction by mixing a phase separation composition comprising a lipophilic solubilizer and water with the primary extraction; and obtaining a non-polar natural substance by separating a top layer of a phase-separated solution.
The extraction method of the present invention
refers to a dissolution-emulsion extract (DEE) for non-polar natural substances. According to DEE, non-polar natural substances in a natural raw material are extracted and mixed with a phase separation composition to be dissolved and emulsified, and then the non-polar natural substances are extracted by phase separation.
The composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease may further comprise at least one selected from the group consisting of a lipophilic solubilizer, a surfactant, and water.
For example, the lipophilic solubilizer may comprise at least one selected from the group consisting of BRIJ 010-SS-(RB), Capryol 90, Capryol PGMC, Gantrez ES-435, Gantrez S-97 BF, Gelucire 43/01, Gelucire 44/14, Gelucire 50/13, Gelucire 48/16, Labrafac CC, Labrafac Lipophile WL1349, Labrafac PG, Labrafil M 1944 CS, Labrafil M 2125 CS, Labrafil M 2130 CS, Lauroglycol 90, Lauroglycol FCC, Monosteol, Peceol, Pharmasolve, Plurol Oleique CC497, Span 20-LQ-(SG), Span 60-PA-(SG), upper Refined Oleic Acid-LQ-(JP), Super Refined Tween Surfadone LP-300, Transcutol HP, Transcutol P, TWEEN 60-SS-(SG), TWEEN 80 HP-LQ-(MH), TWEEN 80-LQ-(SG), Vitamin E TPGS, Miglyol 812, and captax 355. Miglyol 812 and captax 355, which are medium chain triglyceride (MCT) oils, may be used as the lipophilic solubilizer.
For example, as a non-ionic surfactant, the surfactant may comprise at least one selected from the group consisting of Labrasol, Crodex A-PA-(RB), Geleol, Gelot 64, Suppocire AS2X, Suppocire BML, Synperonic PE/F 127, Synperonic PE/L 44, and Tefose 63.
The extraction method is described in detail as below.
First, a primary extract is prepared by extracting natural substances from a Centipeda minima raw material. As an extraction solvent, various solvents such as water and alcohol may be selected and used, and alcohol was used in the present invention. Preferably, methanol or ethanol can be used.
For example, extraction may be performed by selecting any one of methods such as hot water extraction, cold extraction, reflux cooling extraction, solvent extraction, steam distillation, ultrasonic extraction, and elution, and additionally, a conventional fractionation process may be performed.
For example, cold extraction can be performed by immersing a natural raw material in cold alcohol. For example, as a natural raw material, Centipeda minima itself may be used, or a powder obtained by pulverizing the same may be used.
Unlike this, the extraction can be performed by hot water extraction in which a Centipeda minima raw material is immersed in alcohol at a temperature of 100 ° C. or higher for about 1 hour, and about 80% alcohol can be used. For example, a step of removing an alcohol component by concentrating under reduced pressure a primary extract according to hot water extraction may be performed. Although there is no difference in achieving the present invention even if a primary extract that has not undergone a concentrating step is used to directly move on to the next step, an unnecessary alcohol component may preferably be removed in consideration of clearer phase separation and extraction efficiency.
A phase separation composition is added to the primary extract and mixed.
The phase separation composition may comprise a lipophilic solubilizer and water. For example, the phase separation composition may comprise 10 to 90% by weight of a lipophilic solubilizer and 10 to 90% by weight of water.
For example, the phase separation composition may further comprise a nonionic surfactant. The phase separation composition may comprise 40% by weight or less of a nonionic surfactant.
Therefore, the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C contained in a Centipeda minima raw material are primarily extracted as non-polar natural substances, and then mixed with a phase separation composition. Phase separation occurs as a lipophilic solubilizer and non-polar natural substances are contained in one layer, and the remaining water and other components are contained in the other layer.
In Examples of the present invention, when the phase separation composition comprises a nonionic surfactant, in the step of mixing the phase separation composition, the mixture may be heated during mixing for clearer phase separation. For example, the mixture obtained by mixing the phase separation composition with a primary extract may be stirred while maintaining a temperature of 30 to 5 ° C., preferably 35 to 45° C.
When a primary extract is mixed with the phase
separation composition, the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C, which are non-polar natural substances, are extracted with and dissolved in a nonionic surfactant or a lipophilic solubilizer. At this time, when high-speed mixing is additionally performed, the surface area of the surfactant and solubilizer in the mixture is increased, and most of the non-polar natural substances that have not been extracted or dissolved are dissolved, resulting in an instantaneous critical micelle concentration (CMC) state. At that time, when a cloud point is reached as the temperature of the mixed solution increases, since the solubility of nonionic surfactants decreases as the temperature increases, unlike ionic surfactants, the phase separation of the mixed solution becomes more apparent.
The top layer of a phase-separated solution is separated to obtain the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C. After the phase-separated solution is left as it is, it is filtered by centrifugation to obtain the Centipeda minima extract.
The composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease comprises the Centipeda minima extract obtained, and may further comprise a lipophilic solubilizer, a surfactant, and water.
In addition, with the phase separation layer containing the Brevilin A, the Arnicolide D, the Arnicolide C, and the Microhelenin C extracted according to the extraction method, an emulsification composition in a microemulsion range, which is out of the range of the phase separation composition, may be further mixed to prepare an emulsified product.
Products such as natural substances extracted according to the Examples of the present invention and compositions comprising the same can be prepared without using a liquid-liquid extraction method that uses a toxic solvent, and so steps such as drying can be omitted. In addition, since the solvent is a substance that is harmless to human body, an extract containing natural substances can be directly used as a product without any other steps. In addition, microemulsion or CMC may increase the absorption rate of the product.
In general, the use of a surfactant increases the absorption rate by increasing the solubility of a compound using the CMC of the surfactant. Microemulsion can also increase the absorption rate by not only increasing the solubility but also reducing the size of the material to be absorbed.
The products manufactured in this way can be manufactured as products such as hair tonic, hair conditioner, hair lotion, hair nutrition lotion, hair shampoo, hair rinse, hair treatment, hair cream, hair nutrition cream, hair moisture cream, hair massage cream, hair wax, and hair aerosol, hair pack, hair nutrition pack, hair soap, hair cleansing foam, hair oil, hair drying agent, hair preservative, hair dye, hair wave agent, hair bleach, hair gel, hair glaze, hair dressing, hair lacquer, hair moisturizer, hair mousse, and hairspray; and as formulations for external skin application such as cream, gel, patch, spray, ointment, plaster, lotion, liniment, paste, and cataplasma; and can be appropriately applied in a liquid phase, a solid phase, and a gaseous phase.

The present experiment was performed at the
Korea Dermatological Research Institute to confirm the hair growth and hair loss effect of the composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, comprising the Centipeda minima extract.
A sample of the composition for preventing and treating inflammatory disease and autoimmune diseases and non-alcoholic fatty liver disease, comprising the Centipeda minima extract, according to the Example, was administered to a test group, and a sample of a composition comprising Labrafac, Labrasol, and D-panthenol was administered to a control group as a placebo control group. The experiment was performed for 24 weeks, and hair growth and hair loss were observed in an interval of 8 weeks.
There were 72 subjects, including 36 subjects in the test group and 36 subjects in the control group who satisfied the criteria described below.
As an experimental method, the experimental subjects used an appropriate amount of the sample once a day under the supervision of the tester, using it once on the skin after shampooing every evening and sufficiently drying the hair by applying 0.5 mL for each use. Rather than applying the sample to the entire skin in a day, half application was performed by dividing the skin into 2 sections and applying the sample to half of the skin each day over two days.
Use of double-blind method: In sample distribution, the test sample and the control sample were distributed in the same containers so that both the test subjects and the tester could not know the contents of the samples. The sample code used for distinction was sealed so that it could not be exposed, and a classification symbol (A/B) was marked on top of the sample code.
The change of the total hair counts was evaluated with a phototrichogram, and after cutting the hairs on the hair loss area to be evaluated, small dots with a diameter of 1 mm were tattooed or a particular coordinate was recorded. The phototricogram was performed each time around the dot tattoo or the particular coordinate.
The total hair counts (number/cm2) were obtained by observing the number of hairs within a circle of 1 cm2.
The results of the test group (total hair counts) are shown in Table 1.
The results of the control group (total hair counts) are shown in Table 2.
Referring to Tables 1 and 2 above and
For a secondary efficacy evaluation, the degree of hair improvement was visually evaluated by the tester by photography. Photos of the human body were always taken at a predetermined position under the same conditions by using a high-resolution digital camera (DSLR) and compared before and after the application of the test sample.
The degree of improvement of the hair of the test group was evaluated, and the average of the evaluation results is shown in Table 4 below.
The degree of improvement of the hair of the control group was evaluated, and the average of the evaluation results is shown in Table 5 below.
