Abstract
Description
[Technical Field]
[0001] The present invention relates to a composition for delaying aging or extending lifespan, comprising an amino aromatic compound as an active ingredient. [Background technology]
[0002] Living organisms have a limited lifespan and, as time passes, they naturally go through a process of being born, growing, and aging, which eventually leads to death. Aging is one of the most complex biological pathways that occurs in all living organisms.
[0003] Numerous studies have been conducted to clarify the causes and processes of aging, and these are broadly explained by two mechanisms: the aging clock and cellular senescence. The aging clock is a theory that explains aging through telomere replication loss at the ends of DNA, arguing that the depletion of telomeres, which are repetitive sequences found at both ends of each chromosome, can lead to cellular senescence and organismal aging. Cellular senescence views the accumulation of intracellular damage due to oxidative damage, mitochondrial dysfunction, etc., as the main cause of aging, and among these, the mitochondrial reduction theory emphasizes the importance of mitochondrial function in healthy cellular metabolism and bioenergy. The decline in mitochondrial function associated with aging includes decreased ATP production, increased ROS production, decreased mitochondrial number, and changes in mitochondrial permeability.
[0004] As we age, the activity of pathways related to fat metabolism is inhibited. That is, fat breakdown decreases, and the absorption of low-density cholesterol (LDL) by cells decreases, leading to an increase in LDL concentration in the blood, which can cause cardiovascular disease. In addition, aging increases the incidence of neurological diseases such as Alzheimer's and Parkinson's disease, which lead to a decline in cognitive and motor function and reduce the quality of life.
[0005] During the aging process, various physiological changes occur, such as a decrease in body and bone mass, an increase in blood pressure and blood sugar, and a decrease in exercise volume and cardiac output. At the molecular level, aging is characterized by the accumulation of DNA mutations, protein oxidation, and lipid peroxidation. However, the fundamental mechanisms that can explain the changes associated with aging and the increase in mortality have not yet been fully elucidated.
[0006] In addition to research focusing on understanding the aging process, numerous studies on delaying aging and extending lifespan are also underway. The most successful method to date is dietary restriction. The effect of dietary restriction was first reported in rats, and subsequently, a lifespan phenotype due to dietary restriction has been observed in yeast, nematodes, Drosophila, and rats. However, the beneficial effects of dietary restriction as described above are only observed when dietary restriction is continuously maintained, and it is difficult to apply to all living organisms.
[0007] To date, many studies and efforts have been made to fulfill the dream of immortality and longevity, but the mechanism of aging has not yet been fully elucidated.
[0008] On the other hand, amino aromatic compounds are reported to be effective in treating neurodegenerative diseases by scavenging hydrogen peroxide in the blood as a blood hydrogen peroxide scavenger, reducing the relatively high levels of hydrogen peroxide present in pathological conditions such as neurodegenerative diseases, especially Alzheimer's disease, to an appropriate concentration. However, this is to treat neurodegenerative diseases by scavenging excess hydrogen peroxide in the blood, and there has been no research on delaying biological aging or extending lifespan. SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION
[0009] Therefore, the inventors have confirmed that amino aromatic compounds, known as blood hydrogen peroxide scavengers, can delay biological aging and extend lifespan, and have focused on their applicability as uses related to delaying aging or extending lifespan, thus completing the present invention.
[0010] The present invention provides a pharmaceutical composition for preventing or treating an aging-related disease or disorder, containing an amino aromatic compound or a pharmaceutically acceptable salt thereof as an active ingredient.
[0011] The present invention also provides a composition for delaying aging or extending lifespan, containing an amino aromatic compound or a pharmaceutically acceptable salt thereof as an active ingredient.
[0012] The present invention also provides a health functional food composition for preventing or improving an aging-related disease, containing an amino aromatic compound or a food-acceptable salt thereof as an active ingredient.

[0013] To achieve the above object, One aspect of the present invention provides a pharmaceutical composition for preventing or treating an aging-related disease or disorder, containing an amino aromatic compound represented by the following Chemical Formula 1 or a pharmaceutically acceptable salt thereof as an active ingredient. [Chemical Formula 1] JPEG2026522513000002.jpg38170In the above Chemical Formula 1, Ar is C6-C 20 arylene, and the arylene of the Ar may be further substituted with one or more selected from C1-C 10 alkyl, C1-C 10 alkoxy, amino, mono- or di-C1-C 10 alkylamino, halo C1-C 10 alkyl, halo C1-C 10 alkoxy and hydroxy, and may be further substituted, R 1 and R 2 are each independently hydrogen or C1-C 10 alkyl, R 3 is halogen, C1-C 10 alkoxy, halo C1-C 10 alkyl or halo C1-C 10 alkoxy, n is an integer, either 1 or 2.

[0015] Another aspect of the present invention provides a health functional food composition for the prevention or improvement of aging-related diseases, comprising an amino-aromatic compound represented by chemical formula 1 or a food-grade salt thereof as an active ingredient. [Effects of the Invention]
[0016] A composition according to one embodiment can significantly suppress the death of nerve cells due to aging, delay age-related nerve degeneration, improve the survival rate of dopamine-secreting nerve cells, and significantly improve the degree of decline in motor function associated with aging.
[0017] Furthermore, while the size and number of branches of astrocytes tend to decrease and shrink with age, this can be delayed by treatment or administration of the composition according to one embodiment. In addition, as aging progresses, astrocytes overproduce reactive oxygen species and GABA, which cause memory loss and cognitive impairment due to the overproduction of MAOB, but the overproduction of reactive oxygen species and GABA can be suppressed by treatment or administration of the composition according to one embodiment.
[0018] In other words, a composition according to one embodiment can delay the aging of an individual and extend their lifespan, and can prevent or treat age-related diseases or disorders. Furthermore, it can exhibit preventive or restorative effects against age-related decline in motor function. [Brief explanation of the drawing]

[0094] Furthermore, the present invention provides a method for preventing or treating age-related diseases or disorders, or a method for delaying aging or extending lifespan, which includes the step of administering the composition to an individual who has developed or is likely to develop an age-related disease or disorder, or who needs aging delay or life extension.
[0095] Furthermore, the present invention provides a health functional food composition for the prevention or improvement of aging-related diseases, comprising an amino aromatic compound represented by the chemical formula 1 or a food-grade salt thereof as an active ingredient.
[0096] The aforementioned food-grade salts can be obtained by reacting the amino-aromatic compound with an inorganic acid such as hydrochloric acid, bromate, sulfuric acid, nitric acid, or phosphoric acid; a sulfonic acid such as methanesulfonic acid, ethanesulfonic acid, or p-toluenesulfonic acid; or an organic carboxylic acid such as tartaric acid, formic acid, citric acid, acetic acid, trichloroacetic acid, trifluoroacetic acid, capric acid, isobutanoic acid, malonic acid, succinic acid, phthalic acid, gluconic acid, benzoic acid, lactic acid, fumaric acid, maleic acid, or salicylic acid. Alternatively, the amino-aromatic compound can also be obtained by reacting it with a base to form salts such as ammonium salts, alkali metal salts such as sodium or potassium salts, alkali metal salts such as calcium or magnesium salts, salts of organic bases such as dicyclohexylamine, N-methyl-D-glucamine, or tris(hydroxymethyl)methylamine, and amino acid salts such as arginine or lysine.

[0104] [Manufacturing Example 1] Production of amino aromatic compounds JPEG2026522513000010.jpg46170
[0105] An amino-aromatic compound was prepared with reference to Korean registered patent KR10-2643653 B1. The specific preparation process is as follows: Potassium carbonate (3.0 equivalents), potassium iodide (0.1 equivalent), and phenylalkyl bromide compound (b, 1.0 equivalent) were added to an acetonitrile solution containing p-phenylenediamine compound (a, 1.2 equivalents), and the mixture was stirred at 110°C for 36 hours. Next, it was cooled to room temperature, diluted with ethyl acetate, and washed with brine. The remaining organic layer was dried over Na2SO4, and the solvent was removed under reduced pressure. The residue was purified via column chromatography to obtain compound P1. The purified compound P1 was dissolved in dichloromethane (DCM), and then a 4.0 M hydrogen chloride solution was added. Next, it was stirred at room temperature for 48 hours, and the resulting precipitate was filtered to obtain compound P2 in hydrochloride form.
[0106] Using the method described above, an amino aromatic compound in hydrochloride form was produced, and its structure is shown in Table 1 below.
[0107] [Table 1] JPEG2026522513000012.jpg227170
[0108] Animal Husbandry One-year-old C57BL / 6J experimental rats were purchased from Janvier Labs (France) and isolated at the Institute for Basic Science's animal facility for two weeks prior to the experiment. The rats' body weight was measured, and their water intake (in grams) was monitored for three days to calculate the optimal drug concentration for each group. The experimental rats were randomly assigned to drug / control and dosage groups. After drug administration, water intake was observed for one week to ensure there were no changes in daily intake. Drug concentrations were adjusted every three months according to changes in the animals' body weight and water intake. The temperature and humidity in the animal housing room were set to 23±1℃ and 50±5%, maintained on a 12-hour day-night cycle (lights off at 8pm), and samples and water were freely accessible. Basal body temperature and body weight were monitored every two weeks. Animal management and handling followed the guidelines of the Institute for Basic Science's Institutional Animal Management and Use Committee.
[0109] Quantification and statistical analysis All analyses were performed in a blinded manner. Data representation and statistical analysis were performed using GraphPad Prism (Graphpad Software). Image analysis was performed using ImageJ (NIH). Here, p-values less than 0.05 were considered statistically significant (*P<0.05, **P<0.01, ***P<0.001, ****P<0.0001, NS, not significant).
[0110] [Example 1] Confirmation of life extension by amino aromatic compounds We conducted an experiment using 14-month-old female C57BL / 6 rats to confirm the extent to which amino aromatic compounds extend lifespan.
[0111] Fourteen-month-old C57BL / 6 female rats were divided into four groups of 15 rats each for the experiment. All four groups were given the same sample, but the control group was supplied with untreated general drinking water, while the remaining three groups were supplied with water containing the amino aromatic compound KDS12025, with daily intake levels of 0.1 mpk, 1 mpk, and 10 mpk, respectively. The rats' body weight and water intake during the first three days were measured to determine the amount of KDS12025 dissolved in the water. The amount of KDS12025 dissolved in the water was then checked for any abnormalities over the course of one week. Subsequently, the rats' water intake was measured every three months to adjust the drug concentration. In addition, the rats' body weight and body temperature were measured every two weeks, and the number of surviving rats was counted. The experiment was conducted for 24 months.
[0112] The survival rates of C57BL / 6 female rats during the experimental period are shown in Figure 1. From this, it was confirmed that the survival rate increased in the group treated with the amino aromatic compound KDS12025 compared to the control group. In particular, a statistically significant increase in survival time was confirmed in the groups treated with 0.1 mpk and 1 mpk of the amino aromatic compound KDS12025.
[0113] In other words, we confirmed that prolonged treatment with amino aromatic compounds delayed aging in rats, improved their survival rate, and consequently extended their lifespan.
[0114] [Example 2] Animal behavior experiment The animals were allowed one hour to acclimate to the laboratory environment before the experiment, and the experiment was conducted under ambient lighting and white noise. On the day of the experiment, all experimental equipment was cleaned with 10% bleach and 70% ethanol, and then washed with distilled water. Behavioral experiments were conducted at the same time each day. All behavioral recordings were made using the Ethovision XT (Noldus) program.
[0115] In an open field test (OFT), animals were placed in a 40cm x 40cm box and allowed to explore freely for 10 minutes. The total distance traveled and speed were measured during the last 8 minutes of the recording.
[0116] In the Novel Place Recognition Test (NPRT), two identical objects were placed in a 40cm x 40cm box, and animals were allowed to explore them freely. After exploring the objects for 8 minutes, the animals were returned to their cages. 60 minutes later, one of the objects was moved to a different, distant location, and the animals were placed back into the experimental box. The animals' exploration time for each object was recorded for 8 minutes. The recorded videos were analyzed by experimenters who were unaware of the experimental conditions. Exploration was considered to consist of the animals smelling the objects without crawling over them. The discrimination ratio was calculated as follows: (time spent smelling the moved object) / (total time spent smelling both objects).
[0117] In the Y-maze test, animals were placed in the center of a symmetrical Y-shaped maze with three identical "arms" (30 cm long, 15 cm high, and 6 cm wide) and allowed to explore freely for 8 minutes, which was recorded. The number of times the animals entered an "arm" was recorded. An entry was considered only when all four of the animal's feet were inside an "arm". The alternation rate (%) was calculated as follows: Alternation rate (%) = [(Total number of alternations) / (Number of "arm" entries - 2)] × 100.
[0118] In the Elevated Plus Maze (EPMT) test, animals were placed in an open area of a symmetrical cross-shaped maze 60 cm above the ground and observed for 8 minutes to freely explore the maze, which had two "open arms" and two "walled arms" (30 cm long, 6 cm wide, 15 cm high). The total distance traveled, the number of times each "arm" was entered, and the time spent in each "arm" were recorded. An entry was considered successful when the animal's center point was within the area. Time spent in the center area was not included in the time spent in individual "arms".
[0119] Open Field Test (OFT) Results Fourteen-month-old C57BL / 6 female rats were divided into four groups of 15 rats each for the experiment. All four groups were given the same sample, but the control group was supplied with untreated general drinking water, while the remaining three groups were supplied with water containing the amino aromatic compound KDS12025, with daily intakes of 0.1 mpk, 1 mpk, and 10 mpk, respectively. An open-field test (OFT) was performed on C57BL / 6 female rats at 26 months of age after being supplied with water containing KDS12025 for 12 months. The aim was to confirm whether it could prevent age-related decline in behavioral ability beyond simple life extension. A comparison group of 12-month-old C57BL / 6 female rats, representing a time when they were healthy and energetic, was used.
[0120] The overall degree of movement was confirmed by the open-field test results illustrated in Figure 2. From Figure 2, it was confirmed that the average speed (left side of Figure 2) and total distance traveled (right side of Figure 2) of 26-month-old animals (1 year after drug administration) treated with the amino-aromatic compound KDS12025 for an extended period were statistically significantly increased in the KDS12025 1mpk treatment group compared to the control group, indicating improved mobility. The KDS12025 0.1 and 10mpk treatment groups showed a tendency towards increase compared to the 26-month-old control group, but there was no statistically significant difference compared to the 12-month-old comparison group. Average speed and total distance traveled indicate the degree of movement and activity. In other words, it was confirmed that the experimental groups treated with the amino-aromatic compound for an extended period, despite their age, showed a level of mobility equivalent to that of the 12-month-old comparison group.
[0121] Results of the Novel Place Recognition Test (NPRT) Fourteen-month-old C57BL / 6 female rats were divided into four groups of 15 rats each for the experiment. All four groups were given the same sample, but the control group was supplied with untreated general drinking water, while the remaining three groups were supplied with water containing the amino aromatic compound KDS12025, with daily intakes of 0.1 mpk, 1 mpk, and 10 mpk, respectively. A novel spatial cognition test (NPRT) was performed on 26-month-old C57BL / 6 female rats that had been supplied with KDS12025-containing water for 12 months. A comparison group consisted of 12-month-old C57BL / 6 female rats, representing a time when they were healthy and energetic.
[0122] Figure 3 shows the results of a novel spatial recognition test (NPRT) that examined memory, particularly spatial memory. Figure 3 shows that the 26-month-old animal group (1 year after drug administration) treated with the amino-aromatic compound KDS12025 10mpk for an extended period showed a statistically significant improvement in the discrimination index for moving objects compared to the control group, confirming improved spatial memory. The amino-aromatic compounds KDS12025 0.1 and 1mpk showed a tendency to increase the discrimination index, but this was not statistically significant compared to 12-month-old rats. In other words, the group treated with the amino-aromatic compound for an extended period showed spatial memory at a level equivalent to or higher than the 12-month-old control group, despite their age.
[0123] Results of the Y-maze test Fourteen-month-old C57BL / 6 female rats were divided into two groups of 15 rats each for the experiment. Both groups were given the same sample, but the control group was supplied with untreated general drinking water, while the remaining groups were supplied with water containing the amino aromatic compound KDS12025, with a daily intake of 1 mpk. A Y-maze test was performed on 24-month-old C57BL / 6 female rats that had been supplied with water containing KDS12025 for 10 months.
[0124] Spatial memory was evaluated using the Y-maze test, and the results are shown in Figure 4. From Figure 4, it was confirmed that the 24-month-old animal group (1 year after drug administration) treated with the amino aromatic compound KDS12025 for an extended period showed a statistically significantly higher switching ratio compared to the control group, indicating a considerable improvement in memory.
[0125] Results of the Elevated Plus Maze (EPM) test Fourteen-month-old C57BL / 6 female rats were divided into two groups of 15 rats each for the experiment. Both groups were given the same sample, but the control group was supplied with untreated general drinking water, while the remaining groups were supplied with water containing the amino aromatic compound KDS12025, with a daily intake of 1 mpk. An elevated plus maze (EPM) test was performed on C57BL / 6 female rats at 24 months of age after being supplied with water containing KDS12025 for 10 months.
[0126] Anxiety levels were assessed using the Elevated Plus Maze (EPM) test, and the results are shown in Figure 5. From Figure 5, it was confirmed that the 24-month-old animal group (1 year after drug administration) treated with the amino-aromatic compound KDS12025 for an extended period spent in the open arm of the Elevated Plus Maze had a greater total time spent in the open arm compared to the control group, resulting in a significant improvement in anxiety.
[0127] [Example 3] Immunohistochemical staining (IHC) and Scholl analysis (morphological analysis) of brain tissue C57BL / 6 female rats were used as the experimental group, and those drank water containing the amino aromatic compound KDS12025 in a daily intake of 1 mpk from 12 months to 30 months of age. C57BL / 6 female rats that drank regular drinking water were used as the control group. C57BL / 6 female rats aged 18 months were used as the comparison group.
[0128] Immunohistochemical staining After anesthetizing the experimental animals in each group with isoflurane, they were washed with 0.9% saline and administered cold 4% paraformaldehyde (PFA). The brains were excised, fixed by immersion in 4% PFA at 4°C for one day, and dehydrated in 30% sucrose solution for 48 hours. Tissues 30 μm thick were prepared using a freeze-cutting machine and stored in a glycerol-based storage solution until before the experiment. Before staining, brain sections were washed three times with 0.1 M phosphate buffer (PBS) and incubated for 1 hour in staining solution (4% serum, 0.3% Triton X-100 in 0.1 M PBS). Primary antibodies were added to the staining solution at the desired dilution ratio and incubated overnight at 4°C. To remove unbound antibodies, the sections were washed three times with 0.1 M PBS, the corresponding secondary antibodies were added, and the sections were incubated at room temperature for 2 hours. To remove unbound secondary antibodies, the tissue sections were washed three times with 0.1M PBS, the first wash containing DAPI (1:1000) for nuclear staining. The tissue sections were mounted using fluorescent mounting medium (Dako) and dried. Fluorescence images were obtained using a Zeiss LSM900 microscope. For visualization, ZEN Digital Imaging for Light Microscopy blue system (Zeiss, ver.3.2) and ImageJ (NIH, ver.1.54b) software were used.
[0129] The antibodies used in the experiment are as follows: rabbit-anti-AOC1 (aviva #ARP41908_P0050, 1:200), chicken-anti-GFAP (Millipore #AB5541, 1:500), x-anti-NeuN (1:250), rabbit-anti-TH (Pelfreez #p40101-0, 1:500), guinea pig-anti-GABA (Millipore #ab175, 1:200), mouse-anti-MAOB (SantaCruz sc-515354, 1:200), donkey-anti-chicken-647 (1:500), donkey-anti-rabbit-488 (1:200), donkey-anti-rabbit-594 (1:200), donkey-anti-guinea pig-488(1:200), donkey-anti-mouse-594(1:200).
[0130] Sholl analysis (morphological analysis) Sholl analysis was performed using confocal microscopy images, following the reference [Nature Neuroscience volume 23, pages 1555-1566 (2020)]. Images of brain sections immunostained with GFAP antibody were used for Sholl analysis. Using a Sholl analysis plugin applied to the Imagej program (NIH Image, Bethesda, MD), a series of circles were constructed at 5 μm intervals from the center to the end of the GFAP signal. The number of GFAP intersections and the radius of the largest circle crossing the star pattern were measured and analyzed within each circle.
[0131] The hippocampus is a crucial brain region involved in learning and memory. As we age, neurogenesis decreases, axonal degeneration increases, and the volume of the hippocampus is known to decrease. Figure 6 shows the results of measuring the degree of age-related neuronal cell (NeuN) death in the hippocampal region of experimental animals' brains. Figure 6 shows the degree of age-related neuronal cell death and the degree of suppression of death by the amino-aromatic compound KDS12025 using tissue staining. NeuN refers to neuronal cell staining, DAPI refers to cell nucleus staining, and GFAP refers to astrocyte staining. In Figure 6, we confirmed that the 30-month-old control group showed a sharp decrease in hippocampal CA1 pyramidal neurons compared to the 18-month-old comparison group. On the other hand, we confirmed that the 30-month-old experimental group showed statistically significant suppression of age-related neuronal cell death by long-term treatment with the amino-aromatic compound KDS12025. In particular, the experimental group treated with amino aromatic compounds for an extended period expressed neurons at a level equivalent to or higher than the 18-month-old control group, despite aging, confirming that aging-related neuronal degeneration was delayed.
[0132] Previous studies have shown that dopamine neurons are lost in the ventral tegmental area, which is associated with decreased motor function in aged animals. Therefore, we measured the degree of age-related dopamine neuron loss and the results are shown in Figure 7. Figure 7 shows tissue staining that restored age-related dopamine neuron death with the amino-aromatic compound KDS12025. TH indicates dopamine neuron staining, and DAPI indicates cell nucleus staining. From Figure 7, we confirmed that the experimental group treated with the amino-aromatic compound KDS12025 for a long period of time had significantly more viable dopamine neurons expressing tyrosine hydroxylase (TH). On the other hand, the control group of the same age as the experimental group had fewer TH-positive dopamine neurons in the ventral tegmental area and substantia nigra. From this, we confirmed that the experimental group treated with amino aromatic compounds for a long period of time showed a significantly improved survival rate of dopamine neurons compared to the control group of the same age, despite aging.
[0133] Previous studies have shown that with age, the astrocyte area significantly decreases due to atrophy of astrocytes (or star cells), resulting in a reduction in the number of branches and the volume ratio of astrocytes. The pathological phenomena of astrocytes (star cells) were analyzed using immunohistochemistry and Scholl analysis, and the results of this analysis are shown in Figures 8-12. Figure 8 shows the degree of neuronal cell death due to aging and the morphological characteristics of astrocytes using the amino-aromatic compound KDS12025, as shown by tissue staining. NeuN indicates neuronal cell staining, DAPI indicates cell nucleus staining, and GFAP indicates astrocyte staining. Figure 9 shows the measurement of astrocyte size (GFAP area). Figure 10 is a morphological analysis photograph of astrocytes. Figures 11 and 12 show some of the Scholl analysis results. Figure 11 shows the number of intersections between each circle and a cell, starting from the center of the circle (or the center of the cell), during Scholl analysis. In normal cells, the length is long and there are many intersections (degree of differentiation), but in aged cells, the length is atrophied, the length is short, and there are fewer intersections. Figure 12 shows the sum of the number of points where astrocytes intersect the circles in Scholl analysis, in order to examine whether they exhibit morphological characteristics. A higher number of intersections indicates more branching or branching.
[0134] The 30-month-old control group showed a decrease in the astrocyte region due to aging compared to the 18-month-old comparison group. Furthermore, not only was the size of individual astrocytes smaller as measured by Scholl analysis, but the number of branched astrocytes was also significantly reduced. Surprisingly, while the control group showed significant atrophy of astrocytes due to aging, the experimental group of the same age treated with the amino-aromatic compound KDS12025 for an extended period recovered to levels equivalent to or better than the 18-month-old comparison group, despite the progression of aging (Figures 9-12). This suggests that while the size and number of branches of astrocytes tend to decrease with aging, administration of amino-aromatic compounds can delay this process.
[0135] Furthermore, Figure 13 shows the results of an analysis of the expression pattern of MAOB protein, one of the mechanisms of pathological phenomena in astrocytes. GFAP refers to astrocyte staining, and MAOB refers to MAOB protein staining. From this, it was confirmed that in the 30-month-old control group, MAOB was overproduced in astrocytes due to aging, while in the experimental group of the same age that received long-term administration of the amino-aromatic compound KDS12025, MAOB levels decreased. Therefore, it was confirmed that long-term administration of the amino-aromatic compound reduced MAOB production in astrocytes and suppressed the overproduction of reactive oxygen species and GABA, which cause memory decline and cognitive impairment, even as the animals aged.
