The present invention relates to pharmaceutical compositions for the treatment and prevention of obesity, diabetes, metabolic diseases, degenerative diseases and mitochondrial disorders.

Obesity is a condition in which extra calories accumulate in adipose tissue in the body when more calories are consumed than calories consumed due to an abnormally increased body fat amount. Complications due to obesity include hypertension, myocardial infarction, varicose veins, pulmonary embolism, coronary artery disease, cerebral hemorrhage, dementia, Parkinson's type 2 diabetes, hyperlipidemia, stroke, cancer (uterine, breast, prostate, colon cancer, etc.), heart disease, gallbladder Diseases, sleep apnea, arthritis, infertility, venous ulcers, sudden death, fatty liver, hypertrophic cardiomyopathy, thromboembolism, esophagitis, abdominal wall hernia, urinary incontinence, cardiovascular disease, high blood pressure, endocrine diseases (obesity research vol. 12 (8) ), 2004, 1197-1211).

Diabetes is a systemic metabolic disease caused by genetic or environmental factors. It is a condition caused by the absolute or relative lack of insulin in the body and refers to an abnormally high blood sugar level. Diabetes complications include hypoglycemia, ketoacidosis, hyperosmolar coma, macrovascular complications, diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy.

Metabolic Syndrome refers to a syndrome that is accompanied by risk factors such as hypertriglyceridemia, hypertension, abnormal glucose metabolism, abnormal coagulation, and obesity. According to ATP III of the National Cholesterol Education Program (NCEP), published in 2001, ① Abdominal obesity with waist circumference of 40 inches (102 cm) for men and 35 inches (88 cm) for women, ② Triglycerides 150 mg / dL or higher, ③ HDL cholesterol in men 40 mg / dL, women 50 mg / dL or less, ④ blood pressure 130/85 mmHg or more, ⑤ fasting glucose is 110 mg / dL or more. If a patient shows more than two, it is considered a metabolic disease.

Insulin resistance refers to a phenomenon in which even though insulin is normally secreted in the body, their "glucose supplying function" does not occur properly, and glucose in the blood does not enter the cell, resulting in hyperglycemia. Cells do not function properly due to the lack of glucose in the cell, eventually metabolic syndrome symptoms will appear.

Degeneration disease is a term derived from pathological findings and means "when oxygen consumption is reduced." Mitochondrial dysfunction, an organ organ that uses energy in the cell to produce energy, is associated with age-related degenerative disease. It means. In this regard, there are neurodegenerative diseases such as Alzheimer's, Parkinson's disease and huntington's disease (Biochemistry, Molecular Biology, 2004, 11 (2), 16-22).

Diseases due to mitochondrial dysfunction include dysfunction due to swelling due to mitochondrial membrane potential abnormalities, reactive oxygen species, or oxidative stress due to free radicals, dysfunction due to genetic factors, and oxidative phosphorylation for energy production of mitochondria. The disease may be caused by a defect of the disease, such as multiple sclerosis, encephalomyelitis, neuromyelitis, peripheral neuropathy, Ly syndrome, Friedrich's ataxia, Alper's syndrome, MELAS, migraine, psychosis, depression, seizures and dementia , Hypertrophic episodes, optic nerve atrophy, optic neuropathy, retinal pigmentation, cataracts, hyperaldosteronemia, parathyroidism, myopathy, muscle atrophy, myoglobinuria, myotonia impairment, myalgia, motor tolerance, tubulopathy, kidney failure, liver failure , Liver failure, hepatomegaly, iron cell anemia, neutropenia, hypotension Plateletosis, diarrhea, villous atrophy, multiple vomiting, dysphagia, constipation, sensorineural hearing loss, epilepsy, mental retardation, epilepsy, Alzheimer's, Parkinson's, Huntington's disease, etc. may occur (US Patent No. 6,183,948, Korean Patent Application Publication) 2004-7005109, Journal of clinical investigation 111, 303-312, 2003, Mitochondria 74, 1188-1199, 2003, Biochimica et Biophysica acta 1658 (2004) 80-88).

The above-mentioned obesity, diabetes, metabolic diseases, degenerative diseases and diseases caused by mitochondrial dysfunction, etc. are collectively referred to as "disease syndrome" in the present invention.

The best way to improve the symptoms of this disease syndrome is known to be exercise, dietary restriction and weight loss. One common method of exerting an effect on the disease syndrome is to promote energy metabolism to promote the consumption of excess energy remaining in the body so that it does not accumulate. It is believed that an effective method of effectively consuming such surplus energy will be a method for treating the disease syndrome. In order to effectively remove surplus energy, it is important to promote energy metabolism, which is involved in inhibiting fat synthesis, suppressing your life, promoting sugar consumption, promoting fatty acidization, and promoting and activating the production of mitochondria, which are the core of energy metabolism. It is essential to activate all of the factors.

The targets for treating the disease syndrome are hardly known, and many target proteins or genes for treating individual diseases are known, and methods for preventing or treating the diseases have been suggested. However, even the treatment of individual diseases such as obesity and metabolic diseases including diabetes has not been significantly improved. Despite many researches for the treatment of diseases, no suitable drugs have yet been developed to treat various diseases caused by excessive energy and aging.

Many diseases, including disease due to obesity, diabetes, metabolic disease, degenerative diseases and mitochondrial dysfunction, ie disease syndrome, begin with an imbalance of energy metabolism and redox status. For this reason, even in the present invention, a method of confirming the presence or absence of an active effect on AMPK was used as the most basic first verification method for confirming the biological efficacy of the disease syndrome.

On the other hand, when AMPK is activated, various physiological phenomena are affected in the submechanism, and the factors and expression phenomena controlled are as follows.

One. Ambassador related

In muscle tissue and cardiac muscle, AMPK promotes muscle contraction to promote glucose uptake, which activates GLUT 1 or induces migration of GLUT 4 into the plasma membrane regardless of insulin action, thereby enhancing glucose uptake into cells. (Arch. Biochem. Biophys. 380, 347-352, 2000, J. Appl. Physiol. 91, 1073-1083, 2001) After increasing glucose uptake into cells, AMPK activates hexokinase to induce glucose metabolism. It increases flux and also inhibits glycogen synthesis. In cardiac muscle tissue in ischemic state, AMPK activates the phosphorylation process of 6-phosphofructo-2-kinase (PFK-2), which in turn activates a series of metabolic processes, increasing the flow of glucose metabolism (Curr. Biol. 10, 1247-1255, 2000). In addition, the activation of AMPK in the liver inhibits the release of glucose from hepatocytes, and the activity of glucose angiogenesis phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase enzymes has been shown to be inhibited by AMPK (diabetes 49, 896- 903, 2000). This is because AMPK is involved in glycemic control by inhibiting the release of glucose from the liver regardless of insulin.

2. Mitochondria biogenesis

One important function of mitochondria is to perform an oxidative phosphorylation process that converts energy from fuel metabolites such as glucose or fatty acids into ATP. It is known that abnormalities in the function of mitochondria are involved in the pathogenesis of various degenerative diseases associated with aging, namely diabetes, cardiovascular disease, Parkinson's disease and dementia (curr.Opin. Cell Biol. 15, 706-716, Peterson et al. (Science 300, 1140-1142, 2003). The oxidative phosphorylation of mitochondria is reported to be about 40% lower in older people, suggesting that mitochondrial dysfunction may be a cause of insulin resistance. In addition, Lee et al. Confirmed that the amount of peripheral blood mitochondrial DNA decreases before the onset of diabetes (diabetes Res. Clin. Pract. 42, 161-167, 1998). Mitochondrial biogenesis in muscle is known to be accelerated by acclimatization, which increases the metabolic activity of oxidative phosphorylation of muscle cells by constant energy depletion and exercise. Zong et al. (Proc. Natl. Acad. Sci. USA 99, 15983-15987, 2002) describe the biogenesis of mitochondria in muscle cells under the condition of sustained energy depletion using genetically inactivated AMPK mice. Demonstrated the need for AMPK. Putman et al. (J. Physiol. 551, 169-178, 2003) also demonstrated the assumption that AMPK is involved in increasing the volume of mitochondria in connection with continuous exercise.

On the other hand, AMPK has been shown to increase the gene expression of PGC1α, which is known to play an important role in the biogenesis of mitochondria (Endocr. Rev. 24, 78-90, 2003). Raynald et al. (Am. J. Physiol. Endocrinol. Metab. 281, 1340, 2001) suggest that nuclear respiratory factor-1 (NRF-1) is an essential gene for mitochondrial transcription and replication as well as transcription of mitochondrial respiratory proteins. In response to stress it plays an important role in increasing oxidative capacity in muscle cells. Thus NRF-1 is ultimately involved in increasing the biogenesis of mitochondria.

The activation of AMPK is known to increase the enzymatic activity of citrate synthase and 3-hydroxyacyl-CoA dehydrogenase, which are known to increase with the increase in the amount of mRNA and protein of UCP-3 and the volume of mitochondria (J. Physiol. 551). , 169-178, 2003).

3. Fat metabolism control AMPK

The mechanism involved in the fat metabolism of AMPK AMPK inhibits fat synthesis by inducing phosphorylation of acetyl CoA carboxylase. Therefore, it is known to promote fatty acidization by lowering the intracellular concentration of malonyl CoA, an intermediate of fat synthesis and inhibitor of carnitine palmitoyl-CoA transferase (CPT I). CPT I is known as an essential enzyme for fatty acid process by fatty acid entering the mitochondria and is controlled by malonyl-CoA. In addition, AMPK is known to inhibit activity through phosphorylation of HMG-CoA reductas and glycerol phosphate acyl transferase (GPAT), which are involved in the synthesis of cholesterol and triacylglycerol (J. Biol. Chem. 277, 32571-32577, 2002, J.). Appl. Physiol. 92, 2475-2482, 2002).

On the other hand, AMPK activation has been shown to inhibit the activity of pyruvate kinase, fatty acid synthase and ACC through phosphorylation of carbohydrate-response-element-binding protein (ChREBP) (J. Biol. Chem. 277, 3829). -3835, 2002), sterol-regulated-element binding protein-1 (SREBP-1), which plays an important role in the differentiation of adipocytes, is also inhibited by AMPK to inhibit the differentiation of adipocytes.

4. Protein synthesis regulation AMPK

AMPK inhibits mTOR and p70S6K by activating TSC during protein synthesis, thereby inhibiting protein synthesis or inhibiting translation elongation through activation of elongation factor-2kinase and inactivation of eEF2 phosphorylation. EEF2 kinase is a direct inhibitor of AMPK. It was found to be a substrate (J. Biol. Chem. 278, 41970-41976, 2003).

As in the example above, AMPK is in in vitro and in Neil et al. (Nature drug discovery, 3 (April), 340, 2004) have been shown to play a pivotal role in energy metabolism of sugars, proteins and fats in vivo . Patients with metabolic syndrome could be characterized by insulin resistance, obesity, hypertension, dyslipidemia, pancreatic beta dysfunction, type 2 diabetes, and atherosclerosis precursors. The common features linking these various abnormalities were presumed to be due to the abnormal detection of energy levels of AMPK and Malonyl-CoA and the regulation of signaling networks. These dysregulations lead to abnormal fat accumulation, cell dysfunction, and ultimately, dysregulation of cells that cause disease. Evidence also suggests that factors that activate AMPK or that lower Malonyl-CoA may restore or prevent the development of these abnormal diseases and syndromes.

Roger et al. (Cell, 117, 145-151, 2004) suggested that obesity can be targeted by lowering AMPK activity in the pituitary gland and increasing malonyl-CoA content to regulate appetite.

Lee et al. (Nature medicine, 13 (June), 2004) suggest that alpha lipoic acid can treat obesity by controlling appetite by inhibiting AMPK activity in the pituitary gland. It has been reported to be effective for the treatment of obesity because it promotes energy consumption by activating UCP-1, especially in adipocytes.

Diraison et al. (Diabetes 53, S84-91, 2004) reported that the expression of appetite-regulating peptide YY increased fourfold by AMPK activation in pancreatic cells, suggesting that appetite regulation can be achieved in tissues other than the pituitary gland by AMPK. Reported.

Nandakumar et al. (Progress in lipid research 42, 238-256, 2003) suggested that AMPK is a target for the treatment of ischemia reperfusion injuries through the regulation of fat and sugar metabolism in ischemic heart disease.

Min et al. (Am. J. Physiol. Gastrointest Liver Physiol 287, G1-6, 2004) reported that AMPK is effective for regulating alcoholic fatty liver.

Genevieve et al. (J. Biol. Chem. 279,20767-74, 2004) activate AMPK to inhibit new insulin sensitivity by inhibiting the activity of iNOS, an inflammatory mediator in chronic inflammatory conditions, including obesity-related diabetes, or endotoxin shock. Height reported to be effective for mechanism development. In addition, it has been reported that by inhibiting the activity of iNOS, it can be applied to the clinic such as sepsis, multiple sclerosis, myocardial infarction, inflammatory growth disease, and pancreatic beta cells.

Zing-ping et al. (FEBS Letters 443, 285-289, 1999) reported that AMPK activates NO synthase phosphorylation of endothelial cells in the presence of ca-calmodulin in rat muscle and cardiac cells. This means that AMPK is involved in heart disease, including angina.

Javier et al. (Genes & Develop. 2004) reported that lifespan is extended by limiting energy use, which increases the ratio of AMP / ATP in vivo and thus prolongs life by activating α2 of AMPK by AMP. Therefore, it has been reported that AMPK can act as a sensor for detecting the relationship between life extension, energy level and insulin-like signal information.

Meanwhile, since ancient times, Dansam is widely used as an important herbal medicine in Northeast Asia, and it is well known that they have an excellent effect on the prevention and treatment of various cardiovascular diseases. In view of the efficacy of such sweet ginseng, the inventors of the present application, Korean Patent Nos. 2003-0099556, 2003-0099557, 2003-0099657, 2003-0099658, 2004-0036195, 2004-0036197 , No. 2004-0050200 suggested that the major components of Salvia ginseng are excellent drugs to treat obesity, diabetes, metabolic diseases, and the like.

In particular, their pharmacological action as an anticancer agent began to be known in the West, and as noted in US Pat. No. 5,969,163, these tricyclic naphtoquinone derivatives were actually developed into various anticancer agents by various research groups. have.

Techniques for formulation and administration of compounds in this application can be found in “Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, PA, 18th edition, 1990”.

In the pharmaceutical composition according to the present invention, the compounds of Formula 1 may be prepared by various methods based on known methods and / or techniques in the field of organic synthesis, as described below. It is only an example, and other methods may be present.

Preparation Method 1: lapachol  Synthesis of Derivatives and Acid Catalyzed Cyclization Reactions

Since β-lapachone is obtained in a relatively small amount from lapacho trees, while lapachol, which is a raw material for β-lapachone synthesis, is obtained in a large amount from lapacho trees, a method of synthesizing β-lapachone using lapachol has long been developed. It became. L. F. Fieser, {J. Am. Chem. Scoc. 49 (1927), 857}, when lapachol and sulfuric acid are mixed together and vigorously stirred at room temperature, β-lapachone is obtained in a relatively good yield. In general, tricyclic naphthoquinone (pyrano-o-naphthoquinone and furano-o-naphthoquinone) derivatives having a relatively simple structure are synthesized in a relatively good yield through a cyclization reaction using sulfuric acid as a catalyst as shown in the following scheme. To synthesize a variety of compounds of formula (I).

   Lapachol β-lapachone

These processes can be summarized in more general chemical equations as follows.

That is, when 2-hydroxy-1,4-naphthoquinone is reacted with various allylic bromide or its equivalents in the presence of a base, a substance having C-alkylation and O-alkylation reactions is obtained together. Depending on the reaction conditions, it is also possible to synthesize only one derivative. Here, O-alkylated derivatives are converted to another type of C-alkylated derivative through the Claisen Rearrangement reaction by refluxing with a solvent such as toluene or xylene, so that various types of 3-substituted-2-hydroxy-1, 4-naphthoquinone derivatives can be obtained. The various types of C-alkylated derivatives thus obtained may synthesize pyrano-o-naphthoquinone or furano-o-naphthoquinone derivatives among the compounds of Formula 1 by inducing a cyclization reaction using sulfuric acid as a catalyst.

Preparation Method 2: 3- methylene -1,2,4- [3H] naphthalenetrione Using Diels - Alder  reaction

V. Nair et al. Tetrahedron Lett. 42 (2001), 4549-4551}, the various olefins of 3-methylene-1,2,4- [3H] naphthalenetrione produced when 2-hydroxy-1,4-naphthoquinone is heated with formaldehyde. It has been reported that various pyrano-o-naphthoquinone derivatives can be synthesized relatively easily by inducing Diels-Alder reaction with compounds. This method has the advantage of being able to synthesize various types of pyrano-o-naphtho-quinone derivatives relatively simply compared to reactions that induce cyclization of lapachol derivatives under sulfuric acid catalytic conditions.

Preparation Method 3: Radical  By reaction Haloakylation  And cyclization reactions

The methods used for the synthesis of Cryptotanshinone and 15,16-Dihydrotanshinone can also be conveniently used to synthesize furano-o-naphthoquinone derivatives. As described by AC Baillie et al. (J. Chem. Soc. (C) 1968, 48-52), the 2-haloethyl or 3-haloethyl radical species derived from 3-halopropanoic acid or 4-halobutanoic acid derivatives are known. By reacting with 2-hydroxy-1,4-naphthoquinone, 3- (2-haloethyl or 3-halopropyl)-2-hydroxy-1,4-naphthoquinone can be synthesized, which induces cyclization under appropriate acidic catalytic conditions. Thus, various pyrano-o-naphthoquinone or furano-o-naphthoquinone derivatives can be synthesized.

Preparation Method 4: 4,5- Enzofurandione of Diels - Alder  Cyclization by reaction

Another method used for the synthesis of Cryptotanshinone and 15,16-Dihydrotanshinone is JK Snyder et al. (Tetrahedron Letters 28 (1987), 3427-3430). There is a way to notice this. In this method, furano-o-naphthoquinone derivatives can be synthesized by inducing cycloaddition by Diels-Alder reaction between 4,5-Benzofurandione derivatives and various diene derivatives.

In addition, various derivatives can be synthesized using an appropriate synthesis method according to the type of substituents based on the above methods. Specific examples thereof are shown in Table 1 below. Specific preparation methods for these are described in the Examples below.

Experimental Example 3 : β- lapachone  On by AMPK  And ACC Phosphorylation of

It was determined whether β-lapachone (Compound 1) influences phosphorylation of AMPK and ACC, energy regulator proteins in vivo. To investigate the phosphorylation of AMP kinase and acetyl-CoA carboxylase (ACC) by β-lapachone, HepG2 cells were plated in RPMI + 10% FBS medium in 6 well plates at 1 X 105 and grown for 24 hours before RPMI serum-free. After replacement with medium, β-lapachone (10 uM) was treated with control (DMSO) for 30 minutes, 1 hour, 2 hours, 4 hours and 6 hours, respectively. Anti-ACC and Anti-pS79-ACC were used to observe phosphorylated ACC, and Anti-AMPK and Anti-pT172-AMPK were used to observe phosphorylated AMP kinase. In FIG. 4, phosphorylation of AMP kinase by β-lapachone can be observed from an initial time (30 minutes), which can be confirmed to last up to 6 hours. In addition, ACC, known as a target protein of AMP kinase, can be confirmed that phosphorylation. This suggests that AMPK is activated by β-lapachone, thereby inhibiting the activity of acetyl-CoA carboxylase, an important regulator of lipogenesis.

Experimental Example 4 : β- lapachone this endothelial nitric oxide synthase ( eNOS Effect on Phosphorylation of

It is well known that the activation of AMPK activates NRF-1 and promotes mitochondrial biosynthesis. In addition, NO / cGMP activates PGC-1a and NRF-1 to promote mitochondrial biosynthesis. To investigate whether β-lapachone, which activates AMPK, is involved in NO production, phosphorylation was increased to increase endothelial nitric oxide synthase (eNOS) activity. To determine the phosphorylation of eNOS by β-lapachone, HUVEC cells were dispensed into EBM2 + 5% FBS medium in 60 mm plates in 1 X 105 cells, grown for 24 hours, and replaced with EBM2 serum-free medium. 10 uM) were each treated for a defined time. Anti-pS1177 eNOS was used to observe phosphorylated eNOS.

In FIG. 5, the phosphorylation of eNOS was maximized at 30 minutes after β-lapachone treatment and then decreased and could not be observed at 2 hours. Increasing phosphorylation of eNOS by β-lapachone has been linked to β-lapachone as well as to ischemic heart disease, mitochondrial myopathy, as well as to mitochondrial dysfunction (degenerative brain disease, diabetes, cardiomyopathy), and aging-related diseases. Shows the possibility of use for the disease and the like.

As shown in Figure 13, it was confirmed through the Western β-lapachone affects the phosphorylation of AMPK and ACC in the gonads and liver tissue of C57BL / 6 mice. Phosphorylated AMPK is expected to activate energy-related metabolism. ACC affected by AMPK activation is phosphorylated, which inhibits liposynthetic activity and affects lipid metabolism including obesity inhibition.

Experimental Example 7 : β- lapachone  this C57BL / 6 Effects on Gene Expression Involved in Lipid Metabolism in Rats

To investigate the anti-obesity effect of β-lapachone, acetyl CoA carboxylase (ACC) 1 (7,8), which is involved in lipid metabolism in liver and gonad adipose tissue after daily oral administration to obese rats at a concentration of 50 mg / kg ), MRNA levels of ACC2 (9), fatty acid synthase (FAS) (10,11), lipoprotein lipase (LPL) (12-15), stearoyl-CoA desaturase1 (SCD1) (16,17) I wanted to check through. These enzymes play an important role in lipid metabolism: ACC catalyzes the formation of malonyl CoA in acetyl CoA, FAS catalyzes the formation of palmitate in malonyl CoA, and SCD1 catalyzes the formation of monounsaturated fat. It is known to play a decisive role in the formation of triacylglycerol, an energy store. Thus, these enzymes are closely related to obesity, diabetes and lipid metabolism. As shown in FIG. 8, the expression levels of ACC1,2, FAS, LPL, and SCD1 mRNA were significantly decreased in the experimental group to which β-lapachone was administered compared to the control group, and the mRNA level of LPL was increased by 2 times compared to the control group. . It can be estimated that β-lapachone is an effective substance for treating metabolic disease through the increase and decrease of enzyme-related gene expression.

β-lapachone was administered daily to the obese rat by oral administration at a concentration of 50 mg / kg, followed by hexokinase 2 (HK2) (21, 22), glucose transporter (GLUT) 2, GLUT 4 (18, 19) in liver and gonad adipose tissue. , 20) was confirmed by real-time quantitative PCR. GLUT is well known as a protein that enters and consumes glucose in the blood from organs such as liver, adipocytes and muscle cells. HK2 is an enzyme of glucokinase, which is an enzyme that proceeds to glycolysis by phosphorylating proteins. As shown in the results of FIG. 9, the mRNA level of HK2 was decreased compared to the control group, and mRNA expressions of GLUT2 and GLUT4 were significantly increased for enzymes involved in two types of glucose transport. The increase in GLUT2 and GLUT4 promotes the intracellular influx of glucose in the blood, demonstrating the potential of β-lapachone as a treatment for diabetes.

Experimental Example  9: β- lapachone  this C57BL / 6 effect on gene expression of proteins involved in mitochondrial biosynthesis in rats

β-lapachone was administered daily to the obese rat by oral administration at a concentration of 50 mg / kg, followed by peroxisome proliferator-activated receptor coactivator alpha1 (PGC1α) (23,24), nuclear respiratory factor1 (NRF1) ( 25-27), mitochondria transcription factor (mtTFA) (25-27), cytochrome c oxidase (COX) 4, 7 (28,29) mRNA levels were confirmed by real-time quantitative PCR. The protein genes shown in FIG. 10 are representative enzymes involved in the regulation of the biosynthesis of mitochondria, which are involved in the biosynthesis of energy in cells, and are known to be involved in various cellular physiological regulation. The amount of mRNA of these enzymes was increased in the group treated with β-lapachone, although there was some difference in the degree. These results indicate that abnormal mitochondrial activity is reported in various metabolic diseases. By improving this phenomenon, β-lapachone may be a therapeutic agent for metabolic diseases, diseases caused by mitochondrial abnormalities, and energy metabolism-related diseases.

Experimental Example 10 : β- lapachone  this C57BL / 6 In the rat  Effect on gene expression involved in energy metabolism

β-lapachone was administered daily to oral rats at a concentration of 50 mg / kg, and the degree of transcripts of genes involved in energy metabolism in liver and gonad fat tissues was measured by real-time quantitative PCR. Referring to the enzyme shown in Figure 11, PPAR alpha and gamma are enzymes involved in the transcriptional regulation of enzymes involved in energy consumption (30,31), and AMPK functions to maintain energy homeostasis by detecting the ratio of AMP / ATP. AOX is an enzyme that catalyzes the activation of oxidative phosphorylation by oxidizing acyl CoA in a process of lipid metabolism (32, 33). CPT1 is also an enzyme involved in energy metabolism and is well known as an enzyme allowing long chain acyl CoA to enter the mitochondria without going to triacylglycerol (34, 35). In the β-lapachone group, the mRNA of peroxisome proliferator activated receptor (PPAR) alpha remained unchanged and nearly doubled in the case of gamma. In addition, mRNA levels of acyl CoA oxidase (AOX), AMP-activated protein kinase (AMPK) alpha1, 2, and carnitine palmitoyltransferase 1 were increased in the β-lapachone group compared to the control group. This increase in genes suggests that β-lapachone could be a therapeutic agent for energy-related metabolic diseases.

Experimental Example 11 : β- lapachone  this C57BL / 6 SIRT in rats  relation Transcript  Impact on expression

Transcripts of the Sirtuin (SIRT) gene (36,37) in gonad adipose tissue at 7, 28, and 56 days after oral administration of β-lapachone daily to oral rats at 50 mg / kg The degree of was measured using real time quantitative PCR. About 12 SIRT-related transcripts shown in FIG. 12 are known in humans. In particular, SIRT1 is well known as an enzyme involved in longevity, and this enzyme has been reported to increase significantly when limited caloric intake (37). As shown in FIG. 18, SITR1, SIRT3, and SIRT6 are significantly increased, and in the case of SIRT2, SIRT5, and SIRT7, there is no significant difference between the control group and the experimental group.

Experimental Example 12 : β- lapachone  this C57BL / 6 In the rat UCP1 and UCP2  Gene Transcript  Impact on expression

β-lapachone was administered daily to oral rats at a concentration of 50 mg / kg, and the amount of transcript of uncoupling protein 1 & 2 (UCP1 & 2) genes in liver and gonad was measured by real-time quantitative PCR. . UCP 1 & 2 is an enzyme that consumes energy through the generation of heat, and has been reported to be associated with obesity as well as to consume energy without the production of ROS (38, 39). As shown in FIG. 13, the mRNA of UCP1 & 2 was significantly increased by β-lapachone administration. These results indicate that β-lapachone may be a safe metabolic disease treatment by reducing stress caused by ROS that is incidental to energy production.

Experimental Example 13 : β- lapachone  By administration C57BL / 6 obesity In the rat  Body weight and Dietary  Changes over time

FIG. 14 shows changes in dietary weight and body weight per 56 days after β-lapachone was administered daily through the oral cavity at a concentration of 50 mg / kg. During the first two weeks, the amount of meal decreased, but then the same amount as the control group. This is seen as a result of the accelerated breakdown of fats resulting in a sufficient amount of energy. It also shows sustained weight loss for 56 days despite the high fat diet compared to the control.

FIG. 15 is a graph comparing weight change of various organs after administration of β-lapachone in C57BL / 6 obese rats for 56 days compared with the control group. As shown in the figure, the weight of tissue was significantly different due to the decrease of fat content in organ tissue after β-lapachone administration.

Figure 16 shows oil red O staining and electron microscopy to determine the overall appearance and fat accumulation of liver tissue in rats after beta-lapachone administration for 56 days in C57BL / 6 obese rats. In FIG. 16, the rats administered with β-lapachone for 56 days showed a marked loss of visceral fat and weight, a decrease in the size of liver tissue, and a change in color to red. 16 is a result of staining the accumulated fat using oil red O to confirm the improvement of fatty liver was confirmed that more than 90% fat loss compared to the control. 16 shows that the electron microscopic findings of liver tissues significantly reduced fat fear and glycogen storage, improved mitochondrial morphology, increased mitochondrial count, and improved endoplasmic reticulum.

FIG. 17 shows that C57BL / 6 obese mice were orally administered to beta-lapachone at a concentration of 50 mg / kg daily by oral cavity, and at 56 days, rats were opened to perform perilipin staining of gonad adipose tissue. It shows that the size of adipocytes is significantly reduced.

FIG. 18 shows blood TG, cholesterol, and free blood samples at 3, 7, 14, 28, and 56 days after β-lapachone was administered daily through the oral cavity at a concentration of 50 mg / kg in C57BL / 6 obese rats. Changes in fatty acids, glucose, insulin, TNFα, resistin and leptin are shown. Not only did blood and glucose levels improve significantly, but insulin and leptin resistance improved. In addition, blood levels of resistin, which causes insulin resistance, were significantly improved. This result is expected to have excellent effects on fatty liver, hyperlipidemia, type 2 diabetes and insulin resistance.

FIG. 19 shows H & E staining of brown adipose tissue of rats at 56 days after β-lapachone was administered daily through the oral cavity at a concentration of 50 mg / kg in C57BL / 6 obese rats. Significantly reduced adipocyte size.

20 shows electron microscopic findings of brown adipose tissue of rats at 56 days after β-lapachone was administered daily through the oral cavity at a concentration of 50 mg / kg in C57BL / 6 obese rats. It shows that the size of adipocytes is significantly reduced.

Experimental Example 14 : Leptin ( leptin A) receptors Missing  there is ob Of ob  Β- in the mouse lapachone  Changes with administration

FIG. 21 shows changes in dietary weight per body weight (A) and body weight for 56 days with daily oral administration of β-lapachone at 150 or 200 mg / kg concentration to ob / ob mice lacking leptin receptors. Show the change (B). Changes in dietary weight per body weight decreased specifically around 10 days, after which the diet was similar to that of the control group. This is the result of accelerated breakdown of fats, despite a similar diet, which produces a sufficient amount of energy. It also shows sustained weight loss for 56 days despite the high fat diet compared to the control. These results show that β-lapachone effectively reduces body weight in obese mice as well as mice lacking leptin receptors. After 56 days, the rats were opened to show H & E staining (C) and electron microscopy (D) to determine fat accumulation in liver tissue. Figure 21-C shows that H & E staining of liver tissues almost eliminates all fat phobias compared to the control. This result is expected to have an excellent effect on fatty liver even in mice lacking leptin. 21-D shows electron microscopic findings of liver tissue, which significantly reduced fat fear and glycogen storage compared to the control group, improved mitochondrial appearance, and increased the number of endoplasmic reticulum. 21-E shows that the bizarre mitochondrial appearance of the control group was normal and the number increased significantly.

Experimental Example  15: voluntary mobility and ability to spontaneous locomotor activity Β-) lapachone  effect

Three hours after β-lapachone was administered to C57BL / 6 obese rats, spontaneous mobility and activity were measured using Versa MAX Activity Monitors & Analyzers (AccuSan Instruments, Columbus, OH). The monitor, which measures each movement, is a 41cm x 41cm Plexiglas chamber (30 cm high) with infrared rays mounted at 2.5 cm intervals on the x- and y-axes. Measurements were made based on the successive interfering of two different scanning lines as a criterion for distinguishing spontaneous locomotor and repetitive behavior and grooming for simple embellishment. The β-lapachone administration group, excipient administration group (vehicle) and control group were put in each measuring device and the activity and movement were measured for 7 hours. Mice were placed in the measuring device two hours before the measurement to become familiar with the new environment changes. As shown in FIG. 22, there was almost no difference between the excipient-treated group and the control group, but the β-lapachone-treated group showed a significant difference in movement and activity.

Experimental Example 16 : Β- on Endurance Enhancement lapachone  effect

We tried to measure the difference in endurance through swimming. After adding water to a cylindrical barrel of 9.5 cm in diameter and 25 cm in height, β-lapachone was administered to C57BL / 6 obese rats, and after 3 hours, each sample and control group was placed in a cylindrical barrel to be measured simultaneously. Measured. As shown in the results of FIG. 23, it was confirmed that the β-lapachone-administered group was able to continue swimming more than twice by single administration compared to the control group.

Experimental Example 17 Respiratory index ( RQ Β-) lapachone  effect

The purpose of this study was to examine the effect of β-lapachone on fat metabolism by measuring respiratory index (RQ). Oxygen consumption and carbon dioxide production were measured using an Oxyscan open-circuit indirect calorimeter (AccuScan Instruments, Columbus, OH). The device consists of a sealed acrylic device (21 x 21 x 21 cm), each measuring device configured to allow oxygen and carbon dioxide to pass through the detector after fresh air is injected at a rate of 1500 ml / min. The concentrations of these gases were allowed to be recorded in ml / kg body weight / min. RQ was calculated by the formula V CO 2 / V O 2. The β-lapachone administration group, excipient administration group (vehicle) and the control group were put in each measuring device and the RQ was measured for 7 hours. Mice were placed in the measuring device two hours before the measurement to become familiar with the new environment changes. As shown in FIG. 24, it was confirmed that there was a significant difference in the RQ values between the excipient-treated group and the control group in the β-lapachone-administered group.
