Description

IL-6 production inhibitor, anti-inflammatory agent, anti-neurodegenerative agent, anti-psychotic agent, medicine and food

The present invention relates to IL-6 production inhibitors, anti-inflammatory agents, anti-neurodegenerative agents, anti-psychotic agents, medicines and foods using rhinacanthin C.

Microglia is a type of glial cell existing in the central nervous system (brain or spinal cord). Microglia are also called microglial or Hortega cells. Microgel cells are considered as immunocompetent cells like macrophages. Microgel cells have the following functions: antigen presentation that becomes the starting point of immune response, natural immunity to foreign bodies, phagocytosis of waste that is excreted from foreign bodies or metabolism, and neural pathway A variety of functions and tasks are assisted by the formation of various circuits to assist in the production of various substances that affect the surrounding cells.

Microgel cells become active states due to external stimuli, stress, and the like, and produce useful substances such as antioxidants and nutrient factors. However, microglial cells secrete proinflammatory cytokine or chemokine, nucleic acid, glutamic acid and other excitatory amino acids such as Reactive oxygen species, protease, etc. become the starting point of neuroinflammation by harming surrounding cells. Therefore, microglia can also cause neurodegeneration of the central nervous system (see, for example, Non-Patent Document 1).

IL-6 (interleukin-6) is a type of cytokine produced by microglia. IL-6 is known to be closely related to inflammation (for example, refer to Non-Patent Document 2). IL-6 produced by microglia causes inflammation in the central nervous system, becoming Parkinson's disease, Parkinson's syndrome, amyotrophic lateral sclerosis , Multiple sclerosis, multiple sclerosis, stroke (apoplexy), cerebral infarction (cerebral infarction) and cerebral ischemia (cerebral ischemia) cause of neurodegenerative diseases. In addition, inflammation in the central nervous system has also become the cause of schizophrenia, depression, autism spectrum disorder, dependency, and neuropsychiatric disorders of sheep epilepsy (see, for example, non- Patent Document 3). Therefore, it is considered that if the production of IL-6 due to microglia can be suppressed, it is possible to prevent or treat neurodegenerative diseases or mental and neurological diseases, and to suppress or treat symptoms.

However, Rhinobacanthus nasutus (L.) Kurz (also known as Baihe Lingzhi grass) is an evergreen shrub belonging to the family Acanthaceae, which is thought to be native to the Deccan Plateau in southern India. It is known that the whole herb of Ganoderma lucidum has insect repellent, anti-inflammatory, and antibacterial effects on skin fungi (for example, refer to Non-Patent Document 4), and is mainly used as folk medicine or food in China, Taiwan, Thailand, and India. In addition, white crane ganoderma has recently been used as food in Japan. In previous applications filed by the applicant of the present application, it was revealed that Baihe Ganoderma has the ability to remove active oxygen (for example, refer to Patent Document 1); has an excretion promoting effect (for example, refer to Patent Document 2); has an antiallergic effect (for example Refer to Patent Document 3) and have antitumor effect (for example, refer to Patent Document 4).

In addition, a compound of ganoderma lucidum quinone C is contained in ganoderma lucidum (see, for example, Non-Patent Document 5). Baihe Lingzhi quinone C is a compound having a naphthoquinone skeleton, and is represented by the following chemical formula (1).

[Experimental Example] Hereinafter, the present invention will be described in more detail with reference to an experimental example related to the action of Ganoderma lucidum quinone C. In addition, the following test examples are concrete examples, and the present invention is not limited by the following test examples.

In a test example, a test to examine the effect of ganoderma lucidum quinone C was performed in consideration of the influence of a substance that promotes the production of IL-6 in microglia. As substances considered to promote the production of IL-6 in microglia, amyloid β, interferon-γ, and lipopolysaccharide are used.

Amyloid beta is a type of amyloid protein, and can be considered to have direct or indirect toxicity to nerve cells. In the test example, amyloid β (25-35), which is known as a center of action of neurotoxicity, was used as amyloid β. As amyloid β (25-35), those purchased from American Sigma-Aldrich Company (Amyloid β-Protein Fragment 25-35, Cat. No. A4559. Only described below as [Aβ]) were used.

Interferon-γ is a type of cytokine that has antiviral action, NK cell (Natural Killer cell) activity enhancement effect, macrophage activation effect, and the like. On the other hand, interferon-γ also enhances inflammation. In the test examples, the interferon-γ system was purchased from a R & D Systems company in the United States (Recombinant Mouse IFN-gamma Protein, Cat. 485-MI-100. Hereinafter, it will only be described as [IFN-γ]).

Lipopolysaccharides are glycolipids that make up the outer wall of cell walls in Gram-negative bacteria. Lipopolysaccharide acts on cells such as humans to promote the production of proinflammatory cytokines. In the test examples, lipopolysaccharides (Lipopolysaccharides from Escherichia coli0111: B4, Cat. L4391, purchased from Sigma-Aldrich Company in the United States) were used as the lipopolysaccharides. Hereinafter, it is described only as [LPS].

In addition, the white crane ganoderma quinone C used in the test example was a person using the white crane ganoderma lucidum solitary. The one-way method is shown below.

First, 2 kg of dried matter of Rhinocanthus nasutus (L.) Kurz roots was prepared and pulverized with a general-purpose grinder. Next, extraction with 90% ethanol was performed. The extraction was performed by immersing Baihe Lingzhi in 20 L of 90% ethanol for 3 days, and then refluxing the solvent for 1 hour. The extraction liquid and extraction residue were separated by filter paper. This extraction was performed three times for the same raw material in total. The solvent was removed from the extract under reduced pressure to obtain 77.82 g of a dry solid ethanol extract.

After removing 4 g of the above-mentioned ethanol extract as an analysis sample, the remaining amount of 73.82 g of the remaining ethanol extract was liquid-liquid partitioned with hexane and 90% methanol. First, 500 ml of 90% methanol was added to the ethanol extract, and then 500 ml of hexane was further added and shaken for 1 minute. Wait about 10 minutes until the solvent is separated, and collect 90% methanol phase. The same operation was repeated twice more, and the solvent was removed from the obtained 90% methanol phase under reduced pressure to obtain 54.32 g of a dry solid partition.

After removing 4 g of the above-mentioned partition as a sample for analysis, a total of 50.32 g of the remaining partition was liquid-liquid partitioned with methylene dichloride and water. First, 500 ml of purified water was added to the partition, and then 500 ml of dichloromethane was further added and shaken for 1 minute. Wait about 10 minutes until the solvent is separated, and collect the dichloromethane phase. The same operation was repeated two more times, and the solvent was removed from the obtained methylene chloride phase under reduced pressure to obtain 27.55 g of a predetermined partition.

Then, 2.50 g of a predetermined distribution was mixed with 10 g of silicone (general purpose of 0.063 to 0.2 mm). Then, a 200 g column (open column with a diameter of 2 cm, a length of 30 cm, and a volume of about 60 ml) filled with 200 g of silica gel (a general product of 0.040 to 0.063 mm) was prepared to elute the solvent (n-hexane: ethyl acetate). = 4: 1) After equilibrating, a mixture of a predetermined distributor and silicone is left, and elution is performed by using an elution solvent. The amount of the dissolution solvent was 500 ml.

In the silica gel column chromatography, each was divided into about 10 ml and collected in a test tube, and the pattern of precipitation was observed by thin-layer chromatography (TLC). Based on the approximate dissolution pattern, the sample obtained from the first test tube is regarded as the division 2-1 (the amount of the solvent is about 0 to 10 ml), and the result obtained from the second to the third test tubes is regarded as the division. Object 2-2 (the amount of solvent is about 10 ~ 30ml), and those obtained from the 4th to 10th test tubes are regarded as the division object 2-3 (the amount of solvent is about 30 ~ 100ml).

Then, the divisions 2-1 to 2-3 were constructed by comparing the data of ¹ HNMR and ¹³ CNMR with literature values (Journal of Natural Products, Vol. 59, pages 808-811, 1996). Analysis confirmed that the division 2-2 was Ganoderma lucidum quinone C. The amount of the obtained ganoderma lucidum quinone C was 444.2 mg.

In addition, a JEOL JNM-GSX500 type nuclear magnetic resonance spectrum device (manufactured by Japan Electronics Co., Ltd.) was used as the nuclear magnetic resonance spectrum device.

BV-2 cells are produced by Dr. Carina Chen's laboratory in Taipei Medical University in Taiwan. The BV-2 cells were obtained by retrovirus-introducing v-raf / v-myc oncogene into mice's microglia cultured cells, and obtained by strains. The obtained BV-2 cells were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum, 100 units / ml penicillin, and 100 μg / ml streptomycin in the presence of 5% carbon dioxide at 37 ° C. Cultivation in advance was performed.

BV-2 cells were disseminated at a density of 5 × 10 ³ cells / well on a 96-well plate (96 Well Clear Flat Bottom Polystyrene TC-Treated Microplates, Individually Wrapped, with Lid, Sterile (Product # 3599)), cultured at 37 ° C for 16 hours in the presence of 5% carbon dioxide gas. Then, a sample of Ganoderma lucidum quinone C was added to the sample, and Ganoderma lucidum quinone C was added at a predetermined concentration for 4 hours of pretreatment. Furthermore, Aβ-added samples, IFN-γ-added samples, and LPS-added samples were added to each of the substances at a predetermined concentration, and cultured at 37 ° C for 48 hours in the presence of 5% carbonic acid gas.

Supernatant was collected after the culture, and the amount of IL-6 produced was measured by a universal ELISA method. ELISA measurement was performed using Affymetrix Corporation of the United States and eBIOSCIENCE Mouse IL-6 ELISA Ready-SET-Go !. The cell survival rate was calculated by a commonly used MTT test method. Specifically, 10 μl of a 5 mg / ml MTT solution (manufactured by Thermo Fisher Scientific, USA) was added to 100 μl of a cell culture solution, and cultured at 37 ° C. for 1.5 hours in the presence of 5% carbon dioxide gas. Then, the culture medium was removed, and 100 μl of a lysing solution (a solution of 0.04 equivalent concentration of hydrochloric acid in isopropanol) was added to completely dissolve the product, and the cell survival rate was calculated by measuring the absorbance at a wavelength of 570 nm (control 640 nm).

The test examples are divided into a test using Aβ and a test using IFN-γ and LPS. In the test using Aβ, the concentration of quinone C of ganoderma lucidum was 0.25, 0.5 μM, and the concentration of Aβ was 20 μM. In the test using IFN-γ and LPS, the concentration of Baihe Lingzhi quinone C was 0.06, 0.13, 0.25, 0.5 μM, the concentration of IFN-γ was 0.1 ng / ml, and the concentration of LPS was 100 ng / ml.
