One of the factors that contribute to the shortening of the healthy life is the accompanying yearsIncrease in age, nicotinamide Adenine Dinucleotide (NAD) in vivo + ) The production of (2) and the decrease in physical functions and the like.
Here, nicotinamide Adenine Dinucleotide (NAD) + (hereinafter also referred to as NAD)) is a coenzyme that mediates a variety of redox reactions in vivo. NAD levels are known to decrease during aging, causing nuclear and mitochondrial dysfunction, and causing a variety of age-associated pathologies. For example, non-patent document 1 suggests aging or aging-related diseases and intracellular Nicotinamide Adenine Dinucleotide (NAD) + ) Reduced levels, and as NAD + Sirtuin's enzymatic activity of deacetylase-dependent longevity genes is associated with a decrease in Sirtuin's enzymatic activity. In recent years, it has been reported that NAD is used + In addition, sirtuin is activated to obtain an anti-aging effect (non-patent document 2). Therefore, research is being conducted on NAD accompanying the increase in age + Is effective in preventing or improving the decrease of the content of the compound (I), and can be used for searching for ingredients of pharmaceuticals, specific health foods, functional foods, etc.
For example, non-patent document 3 discloses that Nicotinamide Ribose (NR), which is a NAD precursor, induces a protein response for mitochondrial unfolding and synthesis of an antiproliferative protein, thereby activating muscle stem cells (muscs) of aged mice. Furthermore, NR is disclosed to prevent MuSC aging in mouse models of muscular dystrophy, NR delays aging of neural SC (stem cells), melanocyte SC prolongs the lifespan of mice.
Further, nicotinamide Ribose (NR) is shown as NAD in non-patent document 4 + The precursor vitamins are widely used, through a single oral administration of NR, NAD in the blood of humans + The concentration dose dependence increases. Further, non-patent document 5 shows that NMN activates Sirtuin, and specifically shows that natural NAD is administered mainly to normal wild-type mice + Nicotinamide Mononucleotide (NMN) of the intermediate (also known as an intermediate metabolite) was effective at mitigating physiological decline associated with age increase in mice without significant toxicity for 12 months, demonstrating the great potential for NMN as an effective anti-aging intervention in humans.
On the other hand, sesamin and/or episesamin have not been suggested or disclosed at all for its action of elevating Nicotinamide Adenine Dinucleotide (NAD) in vivo.

Detailed Description
The composition of the present invention contains 1 or more sesamins.
Sesamins have an effect of increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD), and have an effect of increasing, suppressing, maintaining or improving the concentration of intracellular Nicotinamide Adenine Dinucleotide (NAD), and are used for increasing the concentration of NAD, suppressing the decrease in the concentration of NAD, maintaining the concentration of NAD, or improving the concentration of NAD. The concentration of Nicotinamide Adenine Dinucleotide (NAD) is increased, and the amount of Nicotinamide Adenine Dinucleotide (NAD) is increased. The NAD concentration refers to the intracellular NAD concentration.
Sesamins have an effect of increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD), and are expected to contribute to the prevention or improvement of aging associated with a decrease in the concentration of NAD by increasing, reducing, suppressing, maintaining, or improving the concentration of NAD. Aging is understood as the phenomenon of decline of physical, physiological and mental functions. After aging-based body changes reach maturity, wrinkles of the skin, loss of hair or teeth, graying of hair, accumulation of fatigue or reduction in recovery power, visual or auditory deterioration, motor function deterioration, reduction in muscle strength or activity, reduction in sleep quality, reduction in bone mass, and the like are observed from about 40 years old. Although aging itself is not called a disease, the decrease in physical function and physiological function increases the risk of so-called senile diseases such as arteriosclerosis, abnormal sugar and lipid metabolism, nerve loss degeneration, osteoporosis, and cataract, and aging related to mental functions such as memory and learning occurs with the deterioration of physical function. Increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD) is effective for preventing or improving aging accompanying the decrease in NAD concentration.
(sesamin compounds)
In the present invention, sesamin compounds are a generic term for compounds including sesamin and analogues thereof. Sesamin is one of the main lignan compounds contained in sesame. Examples of the sesamin analogues include, in addition to episesamin, dioxabicyclo [3.3.0] octane derivatives described in jp-a-4-9331. As 1 or more sesamins, 1 or more of these compounds may be used alone, or 2 or more of them may be used. Specific examples of sesamin compounds include sesamin, episesamin, sesaminol, episesamin, sesamol, sesamolin, and the like, and stereoisomers or racemates thereof may be used alone or in combination. Metabolites of sesamins (for example, as described in Japanese patent application laid-open No. 2001-139579) are sesamin analogs included in sesamins of the present invention, as long as the effects of the present invention are exhibited, and can be used in the present invention. In the present invention, sesamin and/or episesamin may be preferably used as the 1 or more sesamins, and sesamin and episesamin may be more preferably used. When sesamin and episesamin are used, the ratio thereof is not particularly limited, and examples thereof include sesamin: episesamin (weight ratio) is preferably 1.
The sesamin-based compound used in the present invention is not limited at all in terms of its form, production method, and the like. For example, in the case of sesamin, sesamin (referred to as sesamin extract or purified product) extracted from sesame oil by a known method (for example, the method described in japanese patent application laid-open No. 4-9331) can be used. In addition, commercially available sesame oil (liquid) may be used as it is. However, when sesame oil is used, since the flavor peculiar to sesame oil may not be evaluated good in a sensory manner, it is preferable to use a sesamin extract (or a sesamin purified product) which is extracted from sesame oil and is odorless. In addition, when sesame oil is used, since the sesamin content is low, if a preferred amount of sesamin is to be formulated, the volume per unit dose of the formulation composition becomes excessively large, and thus inconvenience may occur at the time of ingestion. In particular, when the preparation is prepared for oral administration, the preparation (tablet, capsule, etc.) becomes too large and causes a trouble in ingestion. Accordingly, from the viewpoint that the intake amount can be small, it is preferable to use a sesamin extract (or a sesamin purified product) derived from sesame oil. Sesamin can also be obtained by synthesis. As a method therefor, for example, sesamin and episesamin can be synthesized by a method of Beroza et al (j.am. Chem. Soc.,78, 1242 (1956)). Sesamin and episesamin metabolites can be synthesized by the method of Urata et al (chem. Pharm. Bull. (Tokyo), 56 (11) 1611-2 (2008)).
Sesamins are contained in natural products or foods and drinks, and are compounds that have been recognized for their high safety because of their abundant experience in eating. Sesamin compounds with ensured safety are suitable for continuous intake and long-term intake.
(nicotinamide riboside (NR), nicotinamide Mononucleotide (NMN) and salts thereof)
The composition of the present invention contains 1 or more selected from Nicotinamide Riboside (NR), nicotinamide Mononucleotide (NMN), and salts thereof.
NR and NMN are intermediates of NAD. NR is known to be converted to NMN by Nicotinamide Ribokinase (NRK) to synthesize NAD + . NR, NMN, and salts thereof are known compounds, and can be produced by known production methods, and commercially available products can be used.
As the salt of NR and/or NMN, a pharmacologically acceptable salt can be used, and examples thereof include an acid addition salt and a base addition salt. Specific examples thereof include metal salts (for example, alkali metal salts such as sodium salt and potassium salt; alkaline earth metal salts such as calcium salt, magnesium salt and barium salt), ammonium salts, salts with inorganic acids (for example, salts with inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, sulfuric acid and phosphoric acid), and salts with organic acids (for example, salts with organic acids such as acetic acid, phthalic acid, fumaric acid, oxalic acid, tartaric acid, maleic acid, citric acid, succinic acid, methanesulfonic acid and p-toluenesulfonic acid).
The salt of NR and/or NMN is preferably a salt that can be used in foods, drinks, pharmaceuticals, and the like, and examples thereof include chloride; alkali metal salts such as sodium salt and potassium salt; alkaline earth metal salts such as calcium salts and magnesium salts. As the salt of NR, nicotinamide ribochloride (chloride) is preferred.
(composition containing 1 or more sesamin selected from Nicotinamide Riboside (NR), nicotinamide Mononucleotide (NMN) and their salts and 1 or more sesamin)
The composition of the present invention contains 1 or more selected from the group consisting of Nicotinamide Riboside (NR), nicotinamide Mononucleotide (NMN) and salts thereof, and 1 or more sesamins. The composition of the present invention contains 1 or more selected from Nicotinamide Riboside (NR), nicotinamide Mononucleotide (NMN) and salts thereof, and 1 or more sesamins as active ingredients. The composition of the present invention may be a composition for increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD).
In the composition of the present invention, the molar ratio of 1 or more selected from NR, NMN and salts thereof to sesamins (1 or more selected from NR, NMN and salts thereof/sesamin) is preferably 1 to 100 from the viewpoint of effectively increasing the effect of increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD), that is, from the viewpoint of effectively increasing the effect of increasing the concentration of NAD, reducing the inhibitory effect, maintaining the effect or improving the effect. The molar ratio of 1 or more selected from NR, NMN and salts thereof to sesamins (1 or more selected from NR, NMN and salts thereof per sesamin) is more preferably 3 to 80, and still more preferably 5 to 50. Since the anti-aging effect is exerted by increasing the concentration of Nicotinamide Adenine Dinucleotide (NAD), that is, increasing, decreasing, inhibiting, maintaining, or improving the concentration of NAD, the composition of the present invention preferably has the molar ratio of NR, NMN, or a salt thereof to sesamins in the above specific range from the viewpoint of the anti-aging effect.
In the present specification, when the amount of NR, NMN or a salt thereof is expressed, a value converted to the amount of Nicotinamide Ribose (NR) is used. The equivalent weight of 1 or more NR selected from NR, NMN and salts thereof is the equivalent value of NR to the total weight of NR, NMN and salts thereof.
The total content of 1 or more sesamins contained in the composition of the present invention is not particularly limited, and may be set according to the form and the like.
The total content of sesamins in the composition of the present invention is, for example, preferably 0.001 wt% or more, more preferably 0.01 wt% or more, still more preferably 0.05 wt% or more, and further preferably 10 wt% or less, more preferably 5 wt% or less in the composition.
