Abstract

The object of the present invention is to provide a composition which is effective in retarding or preventing the development of energy decrease, appearance change, etc. of humans and animals due to aging, and is highly safe even with a long period of taking. The present invention relates to an antiaging composition which comprises reduced coenzyme Q as an active ingredient. By feeding mice which develop the aging symptom early (aging-accelerated model mice) with a feed containing reduced coenzyme Q10 for a long period of time, aging process was prevented and retarded. Furthermore, aging-accelerated model mice fed with reduced coenzyme Q10 for a long period of time showed no toxic symptom, thus it was found that the antiaging composition comprising a composition containing said substance can be made into a safe antiaging composition capable of being taken for a long period of time.

Description

DESCRITPION
ANTIAGING COMPOSITION TECHNICAL FIELD The present invention relates to a composition capable of inhibiting or retarding aging.
BACKGROUND ART The antiaging effect has so far been considered from two aspects. One is the effect on apparent aging, namely skin aging and, specifically, this includes an improvement of wrinkles and freckles. This effect may include retention of skin elasticity and moisture, and the like effects. Mainly, preparations for external use such as cosmetics have claimed such effects, and some products have actually proved to be effective in humans. The other is the effect on bodily aging except for skin aging. As products effective in preventing bodily aging, antioxidant activity-based supplements may be mentioned. However, when examined in detail, the antiaging effects claimed by these supplements are just analogized from the effects obtained in vi tro; and not demonstrated from the effects obtained in vivo . Among the in vitro effects shown by these supplements, for example, there are the lipid peroxidation inhibiting effect, the inhibitory effect on the formation of homocysteine whose content in the body may possibly increase with aging, and the like. However, any positive correlation between these effects in in vitro testing and the in vivo efficacy has not been confirmed. As regards the above-mentioned cosmetics for skin aging, etc., that the influence of oxidative stress on skin aging is great is credible to some extent as demonstrated by the fact of ultraviolet irradiation causing skin deterioration. As for the aging of the living body itself, however, it is considered that the analogy from a mere antioxidant activity is quite insufficient. Although a skin aging inhibitor containing ubiquinone (oxidized coenzyme Q) has been disclosed (Japanese Kohyo Publication 2002-513746), the document gives no description or suggestion about reduced coenzyme Q. Further, a method for the treatment of memory disorder resulting from aging which comprises administering carnitine, if necessary together with a coenzyme Q and/or creatine, is also known in the art (Japanese Kohyo Publication 2003-513039) . In this method, however, carnitine is an essential ingredient. This publication does not mention at all about reduced coenzyme Qio or antiaging; in addition, it does not contain any specific report about an anti-mental disorder effect. Oxidized coenzyme Qio is on sale as an antiaging supplement. In fact, however, its efficacy has not been demonstrated but is merely an analogy from the antioxidant activity of coenzyme Qio- Further, reduced coenzyme Qio has not yet been commercialized because of its ready oxidizability; there is no knowledge in the art about its actual antiaging effect, like oxidized coenzyme Qio.
DETAILED DESCRIPTION OF THE INVENTION It is an object of the present invention to provide a substance or composition capable of preventing (retarding) aging. The present inventors have made intensive investigations to solve the above-mentioned subjects, and as a result, they have found for the first time that reduced coenzyme Qio has a distinct aging-preventing (retarding) effect in the invention. Thus, the present invention relates to an antiaging composition which comprises, as an active ingredient, a reduced coenzyme Q represented by the following formula (1) :
in the formula, n represents an integer of 1 to 12. Coenzyme Q is an essential component widely distributed in living organisms, from bacteria to mammals, and is known to occur as a component of the electron transport system of mitochondria within the cells of living bodies. Coenzyme Q functions as an electron carrier in the electron transport system through repeating the cycle of oxidation-reduction in mitochondria. In addition, it is known that reduced coenzyme Q shows antioxidant activity. In humans, coenzyme Qio in which the side chain of coenzyme Q has 10 repeating units is the main component. As mentioned above, reduced coenzyme Qι0 shows antioxidant activity in vi tro but oxidized coenzyme Qi0 does not show antioxidant activity. However, it is believed that oxidized coenzyme Qio is converted to the reduced form by means of reductase in vivo . As an important feature of coenzyme Qio, its high safety may be mentioned. It is reported that, in a chronic toxicity test in rats, there was no toxic effect even when coenzyme Qio was administered every day for 52 weeks at 1,200 mg/kg/day (K. D. Williams et al . , J. Agric. Food Chem. 47, 3756-3763, 1999). The dose of 1,200 mg/kg/day, when converted to the human basis (body weight 50 kg) , corresponds to 60 g/day. Since the usual dose of coenzyme Qio used as a health food in Europe and America is 100 to 300 mg/day, it is evident that coenzyme Qio is a very highly safe supplement material. Coenzyme Q comprises a reduced coenzyme Q represented by the following formula (1) : OH
in the formula, n represents an integer of 1 to 12, and/or an oxidized coenzyme Q represented by the following formula (2):
in the formula, n represents an integer of 1 to 12. The method of obtaining oxidized coenzyme Q and reduced coenzyme Q is not particularly restricted. Employable are, for example, the method comprising obtaining coenzyme Q in the conventional manner such as synthesis, fermentation or extraction from a natural source, and then concentrating oxidized coenzyme Q fraction or reduced coenzyme Q fraction in the effluent by chromatography. When oxidized coenzyme Q is desired, methods known in the art can be used. When reduced coenzyme Q is desired, an ordinary reducing agent such as sodium borohydride or sodium dithionite (sodium hydrosulfite) , is added to the above coenzyme Q according to need, and the coenzyme Q is reduced in the conventional manner to give reduced coenzyme Q, which is then concentrated by chromatography. Reduced coenzyme Q can also be obtained by the method comprising reacting an existing highly pure coenzyme Q product with such a reducing agent as mentioned above (the method described, for example, in Carpino, L. A. et al, 1989, J. Org. Chem. 54, 3303-3310) . The antiaging composition of the invention is a composition comprising reduced coenzyme Q as an active ingredient. So long as the antiaging composition of the invention contains reduced coenzyme Q as an active ingredient, coenzyme Q is not particularly restricted but may consist of a reduced form alone or may be a mixture with a oxidized form. Coenzyme Q that can be used in the practice of the invention may be any of those having the repeating units in the side chain (n in the formulas) of 1 to 12, as illustrated by the above formulas (1) and (2) . Among them, however, one having the repeating units in the side chain of 10 (n in the above formulas (1) and (2) being 10), namely coenzyme Qio, is particularly preferably used. In cases where coenzyme Q is a mixture of the reduced and oxidized forms, the content of reduced coenzyme Q is preferably not lower than 20% by weight, more preferably not lower than 40% by weight, still more preferably not lower than 50% by weight, relative to the total amount of coenzyme Q. Generally, the upper limit is preferably not higher than 99.5% by weight, but may be not higher than 95% by weight. In the antiaging composition of the invention, the content of reduced coenzyme Q is preferably 0.001 to 99% by weight, more preferably 0.01 to 99% by weight, still more preferably 0.1 to 50% by weight, relative to the whole composition. The antiaging composition of the invention may contain, in addition to coenzyme Q, various additives acceptable from the medical or food hygiene law or the like viewpoint. In cases where it is used as a measure for various diseases, medicaments for the disease (s) concerned can be used in combination. The above-mentioned additives are not particularly restricted but include, for example, excipients/diluents, disintegrants, lubricants, binders, coating agents, colorants, coagulation inhibitors, absorption promoters, solubilizing agents, stabilizers, health food materials, nutritional supplement materials (supplement materials) , and the like. The excipients/diluents are not particularly restricted but include, for example, white sugar, lactose, glucose, corn starch, mannitol, crystalline cellulose, calcium phosphate, calcium sulf te, and the like. The disintegrants are not particularly restricted but include, for example, starch, agar, calcium citrate, calcium carbonate, sodium hydrogen carbonate, dextrin, crystalline cellulose, carboxymethylcellulose, tragacanth, and the like. The lubricants are not particularly restricted but include, for example, talc, magnesium stearate, polyethylene glycol, silica, hydrogenated vegetable oils, and the like. The binders are not particularly restricted but include, for example, ethylcellulose, methylcellulose, hydroxypropymethyllcellulose, tragacanth, shellac, gelatin, gum arabic, polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid, polymethacrylic acid, sorbitol, and the like.

Thus, the above-mentioned antiaging composition can be prepared, for example, by adding, mixing, spraying, including, conjugating, etc. the above-mentioned additives, antioxidants and the like, according to need, to/with reduced coenzyme Q obtained as mentioned above. Further, according to the desired dose form as mentioned below, the composition can also be obtained by adding various additives, solvents, bases and the like, which are accepted as pharmaceutical and/or food additives, to reduced coenzyme Q and subjecting the resulting mixture to processing for preparing various adequate dosage forms, namely to granulation, coating, microencapsulation, inclusion, incorporation, emulsification, suspension, or the like. The dosage form of the antiaging composition of the invention may be either liquid or solid. As for the method of administration, various methods are employable such as oral administration, injection, nasal administration, administration in the form of an ophthalmic solution or suppositories, or eating of a coenzyme Q-containing foodstuff. Generally, oral administration is considered to be most effective method from the dosage and the like viewpoint. When oral administration is difficult, the composition of the invention can be administered by any other route than oral administration without any problem. For example, in patients or aged persons who find difficulty in orally taking nutrients, the recommendable method of administration includes, but is not limited to, administration in the form of suppositories, external preparations for dermal application, or the like. In the case of oral administration, for example, the dose of the antiaging composition of the invention as expressed in terms of the amount of coenzyme Q is preferably 30 to 1,200 g, more preferably 50 to 800 mg, still more preferably 100 to 300 mg, per day per human. The antiaging composition of the invention can prevent or retard the aging of humans and/or animals. The term "aging" as used herein refers, for example, to blunting of behavior, for example decreased activity or decreased passivity, backbone bending, loss of hair, corneal clouding, inflammation periphery of the eye and/or ear, and the like. The administration of the antiaging composition of the invention can delay the onset of, or ameliorate, these aging-associated symptoms. In evaluating such antiaging effects, for example, aging-accelerated model mice, can be used as an in vivo evaluation model. This mouse is a model mouse discovered and bred at Kyoto University, Japan, which develops the state of aging early and markedly. This mouse shows the state of aging quite similar to that of humans, and is a useful model animal for in vivo testing for antiaging effects . The method of preventing aging in an animal according to the invention comprises administering the above' antiaging composition to the target animal. The animal includes mammals, fish, birds, reptiles, insects, and the like. Preferred as the animal are mammals, for example humans. The term "administering" includes, within the meaning thereof, topical, enteral, e.g. oral or rectal, or parenteral administration. As for the route of administration, oral administration is preferred. The reduced coenzyme Q-containing composition of the invention produces excellent effect on preventing or retarding aging.

BEST MODE FOR CARRYING OUT THE INVENTION The following examples illustrate the present invention in further detail. These examples are, however, by no means limitative of the scope of the invention. The purity and reduced coenzyme Qio/ (reduced coenzyme Qio + oxidized coenzyme Qι0) ratio (weight ratio) were determined by the following HPLC analysis.
(HPLC analysis conditions) Column: SYMMETRY C18 (product of Waters Corporation), 250 mm (length), 4.6 mm (inner diameter); mobile phase: C2H5OH:CH3OH = 4:3 (v:v) ; detection wavelength: 210 nm; flow rate: 1 ml/min.; retention time for reduced coenzyme Qio: 9.1 min., retention time for oxidized coenzyme Qio: 13.3 min.
(Production Example 1) Production of reduced coenzyme Qio 100 g of oxidized coenzyme Qio (purity 99.4%) and 60 g of L-ascorbic acid were added to 1,000 g of ethanol, and the mixture was subjected to the reduction reaction while stirring at 78°C. After the lapse of 30 hours, the mixture was cooled to 50°C and, while maintaining that temperature, 330 g of ethanol and 70 g of water were added. This ethanol solution (containing 100 g of reduced coenzyme Qio) was cooled to 2°C at a cooling rate of 10°C/hour with stirring to give a white slurry. The slurry obtained was filtered under reduced pressure, the wet crystals were washed in sequence with cold ethanol, cold water and cold ethanol (the temperature of the cold solvents used being 2°C) , and the wet crystals were further dried under reduced pressure (20 to 40°C, 1 to 30 mmHg) to give 97 g of reduced coenzyme Qio (containing about 1% of oxidized coenzyme Qi0) as white dry crystals. All the operations other than drying under reduced pressure were carried out in a nitrogen atmosphere.
(Production Example 2) Production of reduced coenzyme Qi0 100 g of oxidized coenzyme Qio was dissolved in 1,000 g of heptane at 25°C. While stirring, the solution was gradually added with an aqueous solution prepared by dissolving 100 g of sodium dithionite (purity not lower than 75%) as a reducing agent in 1,000 ml of water, thus allowing the reduction reaction to proceed at pH 4 to 6 at 25°C. After the lapse of 2 hours, the aqueous phase was removed from the reaction mixture, and the heptane phase was washed with 1,000 g of a deaerated saturated aqueous solution of sodium chloride for six times. This heptane phase was subjected to solvent substitution under reduced pressure for preparing a 7% (w/w) ethanol solution of reduced coenzyme Qio at 50°C (the solution containing 100 g of reduced coenzyme Qi0) . 50 g of water was added to this ethanol solution, and the mixture was cooled to 2°C at a cooling rate of 10°C/hour while stirring to precipitate crystals. All the operations were carried out in a nitrogen atmosphere. The slurry thus obtained was filtered under reduced pressure, and the wet crystals were washed in sequence with cold ethanol, cold water and cold ethanol (the temperature of the cold solvents used for washing being 2°C) . The wet crystals were further dried under reduced pressure (20 to 40°C, 1 to 30 mmHg) to give 97 g of reduced coenzyme Qi0 (containing about 1% of oxidized coenzyme Qio) as white dry crystals.
(Example 1) Aging preventing (retarding) effect in aging- accelerated model mice Aging-accelerated model mice (SAMP1, 3-week-old females) were allowed free access to a feed (CE-2, product of CLEA Japan, Inc.) containing 0.2% reduced coenzyme Qio (containing about 1% of oxidized coenzyme Q10) obtained in • Production Example 1, and the aging degree of each mouse was quantified with time according to the aging degree score mentioned below. The dose of reduced coenzyme Qio as estimated from the feed consumption and animal weight corresponded to about 150 to 250 mg/kg/day. A control group was given the feed alone (CE-2, product of CLEA Japan, Inc. ) . The aging-accelerated model mice used were model mice discovered and bred at Kyoto University which develop the state of aging early and markedly. These mice show the state of aging quite similar to that of humans, and are useful model animals for in vivo testing for antiaging effects. The aging degree scoring system employed was the scoring system established by the Council for SAM Research. Thus, scores of 0 to 4 were given to each animal with respect to each of the following 11 items: 1: decrease in activity (searching behavior), 2: decrease in passivity (pinching escaping behavior), 3: loss of hair luster, 4: roughening of hair, 5: loss of hair, 6: skin ulcer, 7: periophthalmic lesions (blepharitis and periophthalmic erosion), 8: corneal clouding, 9: corneal ulcer, 10: cataract, 11: increased anterior or backward spinal • curvature. The conditions found in a group of young mice about 3 months of age were taken as standards and given the score 0 (zero) . Thus, a higher score indicates more advanced aging. The results are shown in Fig. 1. As can be seen in Fig. 1, the aging degree scores could be distinctly prevented from increasing as a result of taking of reduced coenzyme Qio-
(Comparative Example 1) The test of Example 1 was performed in the same manner except that oxidized coenzyme Qio was used in lieu of reduced coenzyme Qio. The dose of oxidized coenzyme Qio as estimated from the feed consumption and animal body weight corresponded to about 150 to 250 mg/kg/day, and it was nearly the same as the dose of reduced coenzyme Qι0. The results are shown in Fig. 2. As a result of taking of oxidized coenzyme Qio, the increases in aging degree score were suppressed to a certain extent but the aging preventing effect thereof was weak as compared .with that of reduced coenzyme Qio.
(Preparation Example 1) Powder Reduced coenzyme Qio (containing about 1% of oxidized coenzyme Qio) was dissolved in propanol and allowed to be adsorbed on macrocrystalline cellulose, which was then dried under reduced pressure. This was mixed with corn starch in a nitrogen flow to give a powder preparation.

This powder was filled into gelatin capsules in the conventional manner. The filled capsules were sealed and packed in a nitrogen atmosphere and stored in a refrigerator. Reduced coenzyme Qio 19.8 parts by weight Oxidized coenzyme Qio 0.2 parts by weight Microcrystalline cellulose 40 parts by weight Corn starch 20 parts by weight Lactose 65 parts by weight Magnesium stearate 3 parts by weight Polyvinylpyrrolidone 2 parts by weight
(Preparation Example 3) Soft capsules Corn oil was warmed to 50°C. Thereto was added with reduced coenzyme Qio (containing about 1% of oxidized coenzyme Qio) melted at the same temperature for dissolution. The solution was encapsulated into soft capsules in the conventional manner. Reduced coenzyme Qio 49.5 parts, by weight Oxidized coenzyme Qio 0.5 parts by weight Corn oil 350 parts by weight
(Preparation Example 4) Tablets Reduced coenzyme Qio (containing about 1% of oxidized coenzyme Qio) was dissolved in propanol and allowed to be adsorbed on microcrystalline cellulose, which was then dried under reduced pressure. This was mixed with corn starch, lactose, carboxymethylcellulose calcium and magnesium stearate in a nitrogen atmosphere, an aqueous solution of polyvinylpyrrolidone was then added as a binder, to the resulting mixture, and the whole mixture was granulated in the conventional manner. To this granulation product, talc was added and mixed as a lubricant, and then the resulting mixture was made into tablets. The tablets were packed in a nitrogen atmosphere and stored in a refrigerator. Reduced coenzyme Qio 19.8 parts by weight Oxidized coenzyme Qio 0.2 parts by weight Corn starch 25 parts by weight Lactose 15 parts by weight Carboxymethylcellulose calcium 10 parts by weight Microcrystalline cellulose 40 parts by weight Polyvinylpyrrolidone 5 parts by weight Magnesium stearate 3 parts by weight Talc 10 parts by weight
