The preventive and relieving medicine for activated matrix metalloproteinase (MMP)-causing disorders and diseases according to the present invention contains the solvent extract of Ganoderma mushroom. The solvent extract of Ganoderma mushroom has MMP inhibiting behaviors and is effective for prevention, suppression, and symptomatic relief of various activated MMP-causing disorders and diseases, such as metastasis of cancers, ulceration, rheumatoid arthritis, osteoporosis, periodontitis, and aging of skin.

## Background
TECHNICAL FIELD
The present invention relates to a matrix metalloproteinase (MMP) inhibitor. More specifically the invention pertains to an MMP inhibitor that has high safety and is expected to have effects on prevention, suppression, and symptomatic relief of various activated MMP-causing disorders and diseases, such as metastasis of cancers, ulceration, rheumatoid arthritis, osteoporosis, periodontitis, and aging of skin.
BACKGROUND ART
Cancer is one of the primary causes of death in most advanced countries. In Japan, the cancer occupies almost 30% of the cause of death. Advancement of surgical treatment and radio therapeutics often allows for removal of the primary focus of a cancer. The still high morbidity is ascribed to the metastatic properties of cancers. In the current state, it is extremely difficult to cure the cancer with multiple metastases. One of the important targets of cancer treatment is thus to establish a method of suppressing metastasis of cancer, in addition to the conventional treatment of the primary focus. In this state, the mechanism of cancer metastasis is gradually being elucidated on the molecular level. The decomposition system of the extracellular matrixes has been noted as one of the metastatic processes.
Metastasis of a cancer represents the state that cancer cells released from a primary site are distributed to the whole body through the blood stream, are delivered live to another organ, and start multiplication in the tissue of the organ. In general, the tumor tissue is surrounded by a dense extracellular matrix. Enzymolysis of the extracellular matrix is necessary for distribution of cancer cells from the primary site. The extracellular matrix is composed of various macromolecules including collagen, elastin, fibronectin, laminin, and proteoglycan. MMP is a group of primary enzymes involved in enzymolysis of the extracellular matrixes. The MMP is activated and has enhanced enzyme expression in the process of vascularization in the cancer tissue or in the process of metastasis of the cancer, as described in Reference 1 cited below. A decrease in enzyme expression and inhibition of the enzymatic activity are thus expected to suppress invasion of cancer cells and thereby metastasis of cancers.

    ‘Retinoid-Mediated Suppression of Tumor Invasion and Matrix Metalloproteinase Synthesis’, Shoenermark M. P. et al, Annals New York Academy of Sciences, Vol. 878, pp 466-486, 1999


In the process of invasion of cancer cells into the macromolecules, collagenolysis is especially a critical step. Decomposition of the type IV collagen present on the basilar membrane of a blood vessel is necessary to allow cancer cells to invade into the blood vessel or to be released from the blood vessel. Liotta et al has found that the action of the type IV collagenolytic enzyme secreted by the cancer cells is an important factor to determine the cancer metastasis power. Gelatinase included in the MMP is an enzyme produced by fibroblasts, endothelial cells, and cancer cells and decomposes the matrixes of the type IV collagen, gelatin, and elastin. A substance having the inhibiting activity, for example, against gelatinase is expected to have the effects of suppressing vascularization in the cancer tissues and metastasis of cancers and to be effective for prevention and treatment of cancers and carcinomas.

The reference 3 cited below has reported that the MMP plays an important role in decomposition of extracellular matrixes in various pathology including cancers, ulceration, rheumatoid arthritis, osteoporosis, and periodontitis. The activated MMP due to external stimuli like ultraviolet radiation decomposes essential components for maintaining the skin structure. The MMP has thus been specifically noted recently as an aging acceleration factor activated by ultraviolet radiation.

The object of the present invention is thus to provide an MMP inhibitor that has inhibiting activity against activation of MMP produced by high metastatic carcinoma cell strains and is effective for prevention and symptomatic relief of various activated MMP-causing disorders and diseases, such as metastasis of cancers.
DISCLOSURE OF THE IVNENTION
The inventors of the present invention targeted plant extracts having high safety and carried out screening of the plant extracts for the MMP inhibiting activity. As a fruit of the extensive studies, the inventors have found that solvent extracts of Ganoderma mushrooms have excellent MMP inhibition effects and high cancer metastasis suppression effects in experiments on lung-metastasized animal models, and have completed the present invention. At least part of the above and the other related objects is thus attained by an MMP inhibitor, which includes a solvent extract of Ganoderma mushroom as an active ingredient.
The present invention is also directed to any of medicines, drugs, pharmaceutical products, quasi drugs, cosmetics, toilet articles, and food products, which includes a solvent extract of Ganoderma mushroom and is applied for prevention, suppression, or symptomatic relief of activated MMP-causing disorders and diseases.


BEST MODES OF CARRYING OUT THE INVENTION
Embodiments of the present invention are discussed below. Ganoderma mushrooms used in the present invention are basidiomycetes applied for galenicals ‘Reishi’ and belong to Ganoderma, Ganodermataceae. The Ganoderma mushrooms include Ganoderma lucidum (Reishi), Ganoderma atrum, and Ganoderma sinense (according to the nomenclature in the cited reference Acta Microbiologica Sinica, 19(3), 265-279, 1979), although this classification is not restrictive. The Ganoderma mushrooms used in the present invention may be any of commercially available ones in Chinese and Japanese markets. Among the Ganoderma mushrooms, Ganoderma lucidum (Reishi) and Ganoderma atrum are preferable, and Ganoderma atrum is most preferable.
Available examples of an extractant include water, lower monohydric alcohols (for example, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, and 2-propanol), liquid polyhydric alcohols (for example, 1,3-butylene glycol, propylene glycol, and glycerol), ketones (for example, acetone and methyl ethyl ketone), acetonitrile, esters (for example, ethyl acetate andbutyl acetate), hydrocarbons (for example, hexane, heptane, and liquid paraffin), and ethers (for example, ethyl ether, tetrahydrofuran, and propyl ether). Preferable are polar solvents like water, lower alcohols, and ketones. The extractant may be one solvent or a mixture of two or more solvents. In the case of medicines for internal application, any solvent suitable for internal application may be selected.
The content of the solvent extract of Ganoderma mushroom is not specifically restricted, but is in a range of 0.0005 to 10.0% by weight or preferably in a range of 0.005 to 5.0% by weight as a dried weight to the whole weight of any of medicines, drugs, pharmaceutical products, quasi drugs, cosmetics, toilet articles, and food products for prevention, suppression, or symptomatic relief of activated MMP-causing disorders and diseases. The content of less than 0.0005% by weight does not ensure sufficient effects of the present invention. The content of greater than 10.0% by weight, on the other hand, does not further enhance the effects and is thus uneconomical.
The solvent extract of Ganoderma mushroom may be used in the form of an extracted solution without any further treatment or with any required treatment, such as concentration, dilution, filtration, or decoloration and deodorization with active carbon or the like. The extracted solution may be evaporated to dryness, spray dried, or freeze dried according to the requirements.

The following describes experimental examples for the detailed discussion of the effects of the present invention.
EXPERIMENTAL 1
MMP Inhibition Test
The solvent extracts of Ganoderma mushrooms were subjected to an inhibition test against gelatinase activity by gelatin zymography. The procedure prepared a 10% SDS-PAGE gel (1 mm thick) containing 0.6 mg/ml gelatin, and made 0.014 ml of a culture supernatant of B16 mouse melanoma cells subjected to gel electrophoresis under non-reducing conditions. The procedure subsequently washed the gel twice with a 2.5% Triton X-100 (Sigma Chemical Co.) solution at room temperature for 30 minutes for removal of SDS, and incubated the washed gel in a 30 mM tris-HCl buffer solution (pH 7.6) containing 200 ml sodium chloride, 5 mM calcium chloride, and 0.01% brij-35 (Sigma Chemical Co.) at 37° C. for 24 hours. Each of the hot water extract of Ganoderma atrum (Preparation 1), the hot water extract of Ganoderma lucidum (Reishi) (Preparation 4), and the equal amount mixture of the hot water extract of Ganoderma atrum and the hot water extract of Ganoderma lucidum (Reishi) was added to the buffer solution, in which the gel was soaked. On completion of the reaction, the gel was stained with a 0.2% Coomassie Brilliant Blue R solution and was decolorized with a 5% methanol-7.5% acetic acid solution. The procedure determined the gelatinase activity detected as a non-stained band on the blue stained gel with a densitometer (Atto Densitograph AE-6905, Atto Co.) and calculated the rate of inhibition. The rate of inhibition (%) was calculated according to Equation (1) given below from the observed values of the densitometer. The results are shown in Table 1. The solvent extracts of Ganoderma mushrooms inhibited gelatinase produced by the B16 mouse melanoma cells in a concentration dependent manner.

EXPERIMENTAL 2
Cancer Metastasis Suppression Test
Each of the hot water extract of Ganoderma atrum (Preparation 1), the hot water extract of Ganoderma lucidum (Reishi) (Preparation 4), and the equal amount mixture of the hot water extract of Ganoderma atrum and the hot water extract of Ganoderma lucidum (Reishi) was repeatedly administered at a concentration of 100 mg/kg to one group of C57BL/6 mice through the abdominal cavity once a day for 1 week. Physiological saline was administered to a control group of mice through the abdominal cavity. Each group included 8 mice in this example. B16 mouse melanoma cells were then injected into each mouse through the tail vein to a density of 1×105 cells per mouse. After the injection, the repeated administration of each sample was continued. The lung was extracted from each mouse 3 weeks after the inoculation of the cancer cells and was fixed in a 10% formalin solution. The procedure divided the formalin-fixed lung into 5 lobes and counted the number of metastasized cell nests on the surface of the lobes. The results are shown in Table 3. Administration of the solvent extracts of Ganoderma mushrooms significantly suppressed formation of the metastasized cell nests, compared with the control group. Namely the solvent extracts of Ganoderma mushrooms had sufficient metastasis resistance.
