Definitions

  • the present invention relates to novel quinazoline derivatives effective in lowering blood glucose level and reducing body weight, and a preparation for treatment and/ or prevention of diabetes and/ or obesity, which comprises the compound as an active ingredient.
  • Diabetes one of the most common modern diseases, is on the increase in Korea, too. Because of its severe symptoms and sequela, the disease is becoming a social problem. Improvement of living standards and environments resulting form economic development has led to lack of exercises, while calorie intake has increased significantly. As a result, obesity and type 2 diabetes are also on the increase. If diabetes persists, blood lipid level increases, not to mention the blood glucose level, leading to cardiovascular diseases such as arteriosclerosis and coronary heart disease and complications such as diabetic kidney and retinal diseases. Therefore, development of a treatment for the above disease is an important issue.
  • IDDM insulin-dependent diabetes mellitus
  • NIDDM non-insulin-dependent diabetes mellitus
  • IDDM insulin-dependent diabetes mellitus
  • NIDDM non-insulin-dependent diabetes mellitus
  • Insulin secretory defect refers to the condition in which the beta cells of the pancreas cannot secrete an adequate amount of insulin depending on the blood glucose level and includes both quantitative and functional secretory defects.
  • Insulin resistance refers to the condition in which target cells fail to respond to ordinary levels of circulating insulin. The cause of insulin resistance is generally thought of as hindered signal transfer after binding to the cell membrane receptor, resulting from genetic factors, obesity, reduced physical activity, hyperglycemia, abnormal blood lipid level, etc. What is important is that the two factors are related with each other. If there is insulin resistance, more insulin has to be secreted to overcome the resistance. And, hyperglycemia caused by insufficient secretion of insulin may aggravate the insulin resistance.
  • type 2 diabetes is related with obesity, but the exact mechanism of the interaction or interrelationship still needs to be elucidated.
  • the focus of the research on the cause of diabetes has recently shifted from "glucose metabolism” to "fatty acid metabolism.”
  • type 2 diabetes patients such lipid metabolism disturbances as increase in blood fatty acid level, increase in neutral fats, decrease in high-density lipoprotein cholesterol, accumulation of fats in muscles, increase in abdominal fats and fatty liver are frequently found, as well as hyperglycemia.
  • insulin resistance is thought to be the most important pathological cause of NIDDM. Insulin resistance is the condition in which glucose is not fully utilized even when there is a sufficient amount of insulin.
  • various hypoglycemic drugs are used to treat insulin resistance. The hypoglycemic drugs are classified as follows depending on the treatment mechanism and the target site:
  • Sulfonylurea based drugs promote the movement of insulin-containing granules in the beta cells of the pancreas, thereby promoting the secretion of insulin at second hand.
  • Sulfonylurea based drugs promote the movement of insulin-containing granules in the beta cells of the pancreas, thereby promoting the secretion of insulin at second hand.
  • Biguanide based drugs transfer glucose to muscle cells and inhibit gluconeogenesis in the liver. They are advantageous in that they do not cause hypoglycemia, but care should be taken for aged people and patients with cardiovascular diseases.
  • ⁇ -Glucosidase inhibitors inhibit the enzymatic action of glucose production in the small intestine, preventing abrupt increase of blood glucose level after meals. With few side effects, the drugs are used to treat mild cases of diabetes.
  • thiazolidione (TZD) based drugs are known to activate PPAR- ⁇ , which participates in the differentiation of fat cells.
  • these oral hypoglycemic drugs are not so effective in reducing blood glucose level and cause side effects, development of safer diabetic treatments is imminent.
  • search for new target proteins capable of regulating the signal transfer system and metabolism processes is essential for development of such treatment drugs.
  • AMPK 5'AMP-activated protein kinase
  • AMPK plays a variety of other roles in the body. Besides controlling insulin production in pancreatic cells, it inhibits activation of acetyl CoA carboxylase
  • ACC HMG-CoA reductase
  • AMPK plays a key role in energy homeostasis control and carbohydrate and lipid metabolism control, as activated by AMFs accumulated by muscle contraction, exercise or energy depletion in cells. Also, it is viewed as new target material for treating metabolic diseases, such as diabetes and obesity, caused by energy imbalance.
  • metabolic diseases such as diabetes and obesity
  • the importance of AMPK in glucose absorption during exercise is widely known.
  • the fact that the action of AMPK is independent of the insulin signal transfer system means that it can become a new target material for treatment of type 2 diabetics, most of whom show troubles with the insulin signal transfer system. Actually, a lot of type 2 diabetics could reduce their blood glucose level through exercise and the diabetic model animal test confirmed that exercise promotes activation of AMPK and decrease in blood glucose level.
  • metformin or thiazolidinedione (TZD) based drugs which are widely used as diabetic treatments at present, reduce blood sugar level partly by an AMPK-involved mechanism.
  • search of the drugs that can activate AMPK will lead to the development of a new-concept treatment that imitates the therapeutic effect of exercise on a variety of metabolic diseases.
  • the present inventors synthesized a novel material that has a remarkable effect in increase of AMPK activity and prevention and/ or treatment of obesity and diabetes and confirmed the effect.
  • the present inventors synthesized several compounds with quinazoline backbones and confirmed that they are superior in reducing blood glucose level and body weight.

Description

QUINAZOLINE DERIVATIVES FOR THE TREATMENT AND PREVENTION
OF DIABETES AND OBESITY
Technical Field
The present invention relates to novel quinazoline derivatives effective in lowering blood glucose level and reducing body weight, and a preparation for treatment and/ or prevention of diabetes and/ or obesity, which comprises the compound as an active ingredient.
Background Art
Diabetes, one of the most common modern diseases, is on the increase in Korea, too. Because of its severe symptoms and sequela, the disease is becoming a social problem. Improvement of living standards and environments resulting form economic development has led to lack of exercises, while calorie intake has increased significantly. As a result, obesity and type 2 diabetes are also on the increase. If diabetes persists, blood lipid level increases, not to mention the blood glucose level, leading to cardiovascular diseases such as arteriosclerosis and coronary heart disease and complications such as diabetic kidney and retinal diseases. Therefore, development of a treatment for the above disease is an important issue.
Diabetes is classified roughly into the insulin-dependent diabetes mellitus (hereunder referred to as "IDDM") and the non-insulin-dependent diabetes mellitus (hereunder referred to as "NIDDM"). The insulin-dependent diabetes mellitus (IDDM), or the type 1 diabetes, refers to a condition in which the beta cells of the pancreas produce little or no insulin due to immunological cause. In contrast, the non-insulin-dependent diabetes mellitus (NIDDM), or the type 2 diabetes, is caused by insulin secretory defect and insulin resistance and accounts for over 95 % of diabetes. Insulin secretory defect refers to the condition in which the beta cells of the pancreas cannot secrete an adequate amount of insulin depending on the blood glucose level and includes both quantitative and functional secretory defects. Insulin resistance refers to the condition in which target cells fail to respond to ordinary levels of circulating insulin. The cause of insulin resistance is generally thought of as hindered signal transfer after binding to the cell membrane receptor, resulting from genetic factors, obesity, reduced physical activity, hyperglycemia, abnormal blood lipid level, etc. What is important is that the two factors are related with each other. If there is insulin resistance, more insulin has to be secreted to overcome the resistance. And, hyperglycemia caused by insufficient secretion of insulin may aggravate the insulin resistance. Accordingly, extensive researches have been conducted to study insulin signal transfer system, glucose transfer and metabolism processes to accurately identify the cause of NIDDM. However, the exact pathological mechanism has yet to be found because the cause of NIDDM is very complicated and diverse and improvement of adequate treatment is being retarded.
It is well known that the type 2 diabetes (NIDDM) is related with obesity, but the exact mechanism of the interaction or interrelationship still needs to be elucidated. On the assumption that obesity and fatty acid metabolism disturbance resulting therefrom may be inseparably related with metabolic diseases, the focus of the research on the cause of diabetes has recently shifted from "glucose metabolism" to "fatty acid metabolism." In type 2 diabetes patients, such lipid metabolism disturbances as increase in blood fatty acid level, increase in neutral fats, decrease in high-density lipoprotein cholesterol, accumulation of fats in muscles, increase in abdominal fats and fatty liver are frequently found, as well as hyperglycemia. Of course, it is not certain as yet whether the trouble with lipid homeostasis results from hyperglycemia due to diabetes or it causes diabetes. Insulin resistance is preceded by excessive accumulation of neutral fats in target organs of insulin, including skeletal muscles, cardiac muscles and liver tissues, or fatty acid metabolism disturbance including increase of free fatty acids in fat tissues. When such a state persists, insulin resistance is aggravated and hyperglycemia occurs after meals or during fasting, which, in turn, aggravates the insulin resistance and fatty acid metabolism disturbance. Other metabolic diseases are induced as the cycle is repeated. This pathological phenomenon is corroborated with relative consistency in in vitro experiments, animal tests and human tests. However, it is still uncertain what causes the lipid metabolism disturbance or by what mechanism the insulin resistance is brought about, interfering with physiological homeostasis. At present, insulin resistance is thought to be the most important pathological cause of NIDDM. Insulin resistance is the condition in which glucose is not fully utilized even when there is a sufficient amount of insulin. Currently, various hypoglycemic drugs are used to treat insulin resistance. The hypoglycemic drugs are classified as follows depending on the treatment mechanism and the target site:
1) Sulfonylurea based drugs promote the movement of insulin-containing granules in the beta cells of the pancreas, thereby promoting the secretion of insulin at second hand. There was a report of severe side effects, including inducement of hypoglycemia, but recently, a drug with minimized side effects was developed. 2) Biguanide based drugs transfer glucose to muscle cells and inhibit gluconeogenesis in the liver. They are advantageous in that they do not cause hypoglycemia, but care should be taken for aged people and patients with cardiovascular diseases.
3) α-Glucosidase inhibitors inhibit the enzymatic action of glucose production in the small intestine, preventing abrupt increase of blood glucose level after meals. With few side effects, the drugs are used to treat mild cases of diabetes.
4) Recently developed thiazolidione (TZD) based drugs are known to activate PPAR-γ, which participates in the differentiation of fat cells. However, because these oral hypoglycemic drugs are not so effective in reducing blood glucose level and cause side effects, development of safer diabetic treatments is imminent. And, since the type 2 diabetes is caused by various reasons in insulin signal transfer system and carbohydrate and lipid metabolism processes, search for new target proteins capable of regulating the signal transfer system and metabolism processes is essential for development of such treatment drugs. Recently, as the role of 5'AMP-activated protein kinase (hereunder referred to as "AMPK") in carbohydrate and lipid metabolism and glucose absorption control is elucidated, the possibility of utilizing the activators of the enzyme as treatment for type 2 diabetes is proposed. The basis is as follows. 1) In the muscle cells of exercised mice, increase of AMP resulting from ATP consumption, which increases activity of AMPK, was found. As a result, increase in glucose absorption was observed.
2) The increase of glucose absorption caused by AMPK is independent of the insulin signal transfer system, which implies that it can be a new target material for most of type 2 diabetics showing abnormality in the insulin signal transfer system.
3) In fact, a lot of type 2 diabetics could reduce their blood glucose level through exercise. Also in the diabetic model animal test, it was found that exercise promotes activation of AMPK and decrease in blood glucose level.
4) AMPK plays a variety of other roles in the body. Besides controlling insulin production in pancreatic cells, it inhibits activation of acetyl CoA carboxylase
(ACC) and HMG-CoA reductase in fat cells, thereby inhibiting fat production and cholesterol synthesis. Thus, it is important in controlling obesity.
To conclude, AMPK plays a key role in energy homeostasis control and carbohydrate and lipid metabolism control, as activated by AMFs accumulated by muscle contraction, exercise or energy depletion in cells. Also, it is viewed as new target material for treating metabolic diseases, such as diabetes and obesity, caused by energy imbalance. The importance of AMPK in glucose absorption during exercise is widely known. The fact that the action of AMPK is independent of the insulin signal transfer system means that it can become a new target material for treatment of type 2 diabetics, most of whom show troubles with the insulin signal transfer system. Actually, a lot of type 2 diabetics could reduce their blood glucose level through exercise and the diabetic model animal test confirmed that exercise promotes activation of AMPK and decrease in blood glucose level. There is a report that metformin or thiazolidinedione (TZD) based drugs, which are widely used as diabetic treatments at present, reduce blood sugar level partly by an AMPK-involved mechanism. Thus, search of the drugs that can activate AMPK will lead to the development of a new-concept treatment that imitates the therapeutic effect of exercise on a variety of metabolic diseases.
However, there are a few reports about AMPK activators which are selectively effective against type 2 diabetes and obesity and significantly reduce blood glucose level in diabetic animal tests.
The present inventors synthesized a novel material that has a remarkable effect in increase of AMPK activity and prevention and/ or treatment of obesity and diabetes and confirmed the effect.
To solve the above-mentioned problems, the present inventors synthesized several compounds with quinazoline backbones and confirmed that they are superior in reducing blood glucose level and body weight.
Therefore, in an embodiment of the present invention there is provided a novel quinazoline compound effective in reducing blood sugar level and body weight, which is essential in treating diabetes and obesity. In an embodiment of the present invention there is provided a treatment for diabetes and obesity with no toxicity or side effects, which comprises the novel quinazoline compound, a pharmaceutically available salt thereof or a pharmaceutically available prodrug thereof as an active ingredient.

[Composition]
Active ingredient 5 g, cetyl palmitate 20 g, cetanol 40 g, stearyl alcohol 40 g, isopropyl myristrate 80 g, sorbitan monostearate 20 g, polysorbate 60 g, propyl p-oxybenzoate 1 g, methyl p-oxybenzoate 1 g, phosphoric acid and purified water proper quantity.
Preparation Example 3: Preparation of injections
An injection with the following composition was prepared. [Composition] Active ingredient 100 mg, mannitol 180 mg, dibasic sodium phosphate 25 mg, water for injection 2974 mg. Experimental Example 1. Analysis of glucose absorption
C2C12 muscle cells were cultured in DMEM (Dulbecco's modified Eagle's medium) containing 10 % bovine calf serum. When the cell density increased to about 85 to 90 %, the culture medium was replaced with 1 % bovine calf serum and cell differentiation was induced for 6 days. Completely differentiated cells were cultured for 3 hours with Krebs-Ringer buffer (KRB) containing 5 mM glucose. The test materials were added at a concentration of 10 μM. 30 minutes later, 0.2 μCi 2-deoxyglucose was added. KRB was removed 20 minutes later and the cells were washed for 3 times with cold PBS. The cells were lysed with 0.5N NaOH and counted using a radioactive counter.
As seen in Table 2 below, the group treated with the compound represented by the formula 1 showed glucose absorption 2.8 times as large as the control group.
Table 2
Experimental Example 2. Measurement of AMPK activity by Western blot
C2C12 cells were cultured and differentiated in the same manner as in Experimental Example 1. Treatment with the test materials was also performed in the same manner as in Experimental Example 1 (10 μM for 50 minutes). The culture medium was removed and the cells were washed for 2 times with PBS and protein extracts were obtained using a lysis buffer (50 mM tris-HCl, pH 7.4, 1 % NP-40, 0.25 % sodium deoxycholate, 150 mM NaCl, 1 mM EDTA, 1 mM PMSF, 1 mM sodium o-vanadate, 1 mM NaF, 1 μg/ mL apronitin, 1 μg/mL leu-peptin, 1 μg/mL pepstatin). The AMPK activity was determined from Western blot analysis of the degree of phosphorylation of serine-79 by acetyl CoA carboxylase and the degree of phosphorylation of threonine-172. The amount of ERK
(extracellular signal regulated protein kinase) was confirmed by Western blot in order to quantify the proteins.
The result of Western blot analysis is given in Table 3 below, wherein "strong" means that the degree of phosphorylation of threonine-172 increased by 3 times or more, "mild" means that the degree of phosphorylation of threonine-172 increased by 1 to 3 times and "weak" means that the degree of phosphorylation of threonine-172 increased by less than 1 time.
Table 3
As seen in Table 3, FIG. 1 and FIG. 2a to FIG. 2g, increase of AMPK activity was observed when the muscle cells were treated with the compound represented by the formula 1. Experimental Example 3. Preventive and therapeutic effect for diabetes/obesity in db/db mice
8- to 9-week-old male db/db mice (C57BL/Ks) were tested. 0.5 % carboxylmethylcellulose (CMC), rosiglitazone dissolved in 0.5 % carboxylmethylcellulose (CMC) and the test material were administered orally or abdominally every afternoon to the negative control group, the positive control group and the test group, respectively. Blood glucose level measurement was made just before the administration, at an interval of 3-4 days, by incising the tail vein. Body weight and the amount of feed were measured every day just before the administration.
After 10 days of administration, blood glucose level measurement and body weight measurement, serum was separated from blood for measuring the biochemical parameters related with liver function, kidney function and lipid level.

Experimental Example 4. Preventive and therapeutic effect for diabetes/obesity in ob/ob mice Experimental Example 4-1
6- week old male ob/ob mice (Harlan) were accustomed to the environment of the animal breeding facility of SK for a week. During the period, the mice were freely given feed and water. The mice were grouped based on the body weight. The mice were grouped into the control group, the positive control group (sibutramine) and the test group. The administration dosage was 15 mg/kg for the positive control group and 200 mg/kg/10 mL for the test group. Administration was given abdominally using an insulin syringe. Administration was given once a day at 5 p.m. over a 4-week period. The control group was administered with 0.5 % carboxymethyl cellulose (CMC), at kg/ 1O mL.
Body weight was measured over the 4-week period. The difference in the body weight of the control group and the body weight of the test group (g) and the increase of the body weight (%) were calculated to evaluate the inhibitive effect against body weight increase. Also, the amount of feed intake was measured in order to evaluate the inhibitive effect against feed intake.
