Definitions
- the present invention relates to a novel class of five- and six-membered cyclic carbamate derivatives, a process for the preparation thereof, and pharmaceutical compositions containing the same and their use as therapeutic agents, particularly as cholesterol ester transfer protein inhibitors. Background technique
- Hypercholesterolemia particularly high serum levels of low-density ester protein cholesterol, shows a risk of arteriosclerotic disease.
- atherosclerosis and its associated coronary heart disease (CHD) stroke and peripheral vascular disease have become a huge obstacle to the global industrialization of the health care system.
- CHD coronary heart disease
- CVD coronary heart disease
- LDL low-density lipoprotein
- HDL high-density lipoprotein
- Increasing low-density lipoprotein (LDL) cholesterol levels increases the risk of atherosclerosis.
- epidemiological studies have shown that lowering high-density lipoprotein (HDL) cholesterol levels will also increase the risk of atherosclerosis.
- HDL high-density lipoprotein
- HMG-CoA 3-hydroxy-3-methylglutaryl coenzyme
- reductase inhibitors and clofibrate can only partially increase high-density lipoprotein (HDL) cholesterol levels, and niacin derivatives can significantly increase HDL, but Serious tolerance problems. Therefore, there is a need for drugs that can significantly increase high-density lipoprotein (HDL) cholesterol levels and are well tolerated to prevent atherosclerosis.
- Metabolic control of lipoprotein levels is a complex and dynamic process involving multiple factors. Many ester proteins in the patient's catabolic regulation mechanisms are related. Among them, cholesterol ester transfer protein (CETP) is an important lipoprotein level metabolic control factor, which is a 70,000 Dalton glycoprotein present in the plasma of humans and other animals. Transports cholesterol esters, triglycerides, and certain phospholipids between protoplast lipoprotein particles.
- the above lipoprotein microparticles include high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and chylomicrons.
- CETP catalyzes the transfer of cholesterol esters from high-density lipoprotein (HDL) to apoprotein-containing apoprotein B, especially to very low-density lipoproteins (Hesler, CB, et. al. (1987) Purification and Characterization of human plasma cholesteryl ester transfer protein. J. Biol. Chem.
- CETP lipid transfer activity in pharmacy may increase high-density lipoprotein (HDL) cholesterol levels while lowering low-density lipoprotein (LDL) levels, which is beneficial to the human body.
- HDL high-density lipoprotein
- LDL low-density lipoprotein
- CETP inhibitors have shown that the body can use this mechanism to increase circulating high-density lipoprotein (HDL) cholesterol levels.
- One study showed that using CETP inhibitors at a dose of 900 mg per day increased HDL cholesterol by 34% after 4 weeks (Circulation, 2002, 105: 2159).
- the highest dose was administered twice a day at 120 mg twice daily, and high-density lipoprotein (HDL) cholesterol was increased by 106% after 4 weeks (N. Engl. J. Med. , 2004, 350: 1505-15).
- High-density lipoprotein (HDL) cholesterol levels in plasma by inhibiting CETP activity may give people the anti-atherosclerosis.
- CETP inhibitors have been shown to have anti-atherosclerotic effects in rabbits, this has not been confirmed in humans (Nature 2000, 406: 203-2071).

Description
氨基甲酸酯类衍生物及其在医药上的应用 技术领域 Carbamate derivatives and their application in medicine
本发明涉及一类新的五元及六元环氨基甲酸酯类衍生物, 其制备方法及含有 该衍生物的药物组合物以及其作为治疗剂特别是作为胆固醇酯转移蛋白抑制剂 的用途。 背景技术 The present invention relates to a novel class of five- and six-membered cyclic carbamate derivatives, a process for the preparation thereof, and pharmaceutical compositions containing the same and their use as therapeutic agents, particularly as cholesterol ester transfer protein inhibitors. Background technique
高胆固醇血症,特别是低密度酯蛋白胆固醇的高血清水平, 显示出动脉硬化 疾病的危险性。 目前, 动脉粥样硬化及其引起的冠状动脉心脏病 (CHD)、 中风和 外周血管性疾病己经成为医疗保健体系全球工业化的一个巨大阻碍。 仅在美国, 大约有 1300万人患有冠状动脉心脏病 (CHD), 而每年因此死亡的人数超过 50万, 并且这个数字仍在不断增长。尽管人们尝试通过合理饮食和药物疗法来治疗血脂 障碍, 冠状动脉心脏病 (CHD)仍然以占总死亡数 44%的比例成为美国最常见的死 亡原因, 而其中的 53 %都是由动脉粥样硬化引起的。 Hypercholesterolemia, particularly high serum levels of low-density ester protein cholesterol, shows a risk of arteriosclerotic disease. At present, atherosclerosis and its associated coronary heart disease (CHD), stroke and peripheral vascular disease have become a huge obstacle to the global industrialization of the health care system. In the United States alone, approximately 13 million people have coronary heart disease (CHD), and the number of deaths per year exceeds 500,000, and this number is still growing. Despite attempts to treat dyslipidemia through proper diet and medications, coronary heart disease (CHD) is still the most common cause of death in the United States at 44% of all deaths, and 53% of them are atherosclerotic. Caused by hardening.
动脉粥样硬化的产生是与其血脂水平是紧密相关的。高水平的低密度脂蛋白 (LDL)胆固醇是公认的血脂障碍形式, 但它决不是造成冠状动脉心脏病 (CHD)的 唯一因素。 低水平的高密度脂蛋白 (HDL)胆固醇也是造成冠状动脉心脏病 (CHD) 的危害因素 (Gordon, D. J., et al., "High-density Lipoprotein Cholesterol and Cardiovascular Disease", Circulation, (1 989), 79: 8-1 5)。 升高低密度脂蛋白(LDL) 胆固醇水平将增加动脉粥样硬化的危险度。最近, 流行病学会研究表明降低高密 度脂蛋白 (HDL)胆固醇水平也将增加动脉粥样硬化的危险度, 。 The production of atherosclerosis is closely related to its blood lipid level. High levels of low-density lipoprotein (LDL) cholesterol are recognized as forms of dyslipidemia, but it is by no means the only cause of coronary heart disease (CHD). Low levels of high-density lipoprotein (HDL) cholesterol are also a contributing factor to coronary heart disease (CHD) (Gordon, DJ, et al., "High-density Lipoprotein Cholesterol and Cardiovascular Disease", Circulation, (1 989), 79: 8-1 5). Increasing low-density lipoprotein (LDL) cholesterol levels increases the risk of atherosclerosis. Recently, epidemiological studies have shown that lowering high-density lipoprotein (HDL) cholesterol levels will also increase the risk of atherosclerosis.
众所周知,增加 HDL胆固醇水平可以预防或者治疗动脉硬化性疾病。然而, 目前没有较好的升高高密度脂蛋白 (HDL)药物。 3-羟基 -3-甲基戊二酰辅酶 (HMG-CoA)还原酶抑制剂和氯贝特只能部分提高高密度脂蛋白 (HDL)胆固醇水 平, 烟酸衍生物能明显增加 HDL, 但有严重的耐受性问题。 因此, 需要有一些 可以明显升高高密度脂蛋白 (HDL)胆固醇水平且耐受性良好的药物来阻止动脉 粥样硬化。 It is well known that increasing HDL cholesterol levels can prevent or treat arteriosclerotic diseases. However, there is currently no good high-density lipoprotein (HDL) drug. 3-hydroxy-3-methylglutaryl coenzyme (HMG-CoA) reductase inhibitors and clofibrate can only partially increase high-density lipoprotein (HDL) cholesterol levels, and niacin derivatives can significantly increase HDL, but Serious tolerance problems. Therefore, there is a need for drugs that can significantly increase high-density lipoprotein (HDL) cholesterol levels and are well tolerated to prevent atherosclerosis.
脂蛋白水平的代谢控制是一个涉及到多种因素的复杂而动态的过程。病人分 解代谢调节机制中的很多酯蛋白是有关联的。 在它们中, 胆固醇酯转移蛋白 (cholesteryl ester transfer protein, CETP)是一个重要的脂蛋白水平代谢控制因素, 它是一种出现在人类和其他动物血浆中的具有 70,000道尔顿的糖蛋白, 负责在 原生质脂蛋白微粒间传输胆固醇酯、甘油三酯和某些磷脂。上述脂蛋白微粒包括 高密度脂蛋白 (HDL),低密度脂蛋白 (LDL),极低密度脂蛋白 (VLDL)和乳靡微粒。 CETP能催化胆固醇酯从高密度脂蛋白 (HDL)转移到含有脂蛋白的脱辅基蛋白 B 中, 尤其是转移到极低密度脂蛋白中 (Hesler, C.B., et. al. (1987) Purification and characterization of human plasma cholesteryl ester transfer protein. J. Biol. Chem.Metabolic control of lipoprotein levels is a complex and dynamic process involving multiple factors. Many ester proteins in the patient's catabolic regulation mechanisms are related. Among them, cholesterol ester transfer protein (CETP) is an important lipoprotein level metabolic control factor, which is a 70,000 Dalton glycoprotein present in the plasma of humans and other animals. Transports cholesterol esters, triglycerides, and certain phospholipids between protoplast lipoprotein particles. The above lipoprotein microparticles include high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL) and chylomicrons. CETP catalyzes the transfer of cholesterol esters from high-density lipoprotein (HDL) to apoprotein-containing apoprotein B, especially to very low-density lipoproteins (Hesler, CB, et. al. (1987) Purification and Characterization of human plasma cholesteryl ester transfer protein. J. Biol. Chem.
262(5), 2275-2282)。 在生理条件下, 净反应是一个由 CETP带着甘油三酯从脱辅 基蛋白 B 脂蛋白转移到高密度脂蛋白 (HDL)同时将胆固醇酯从高密度脂蛋白 (HDL)运输到脱辅基蛋白 B脂蛋白的交换反应。一些研究清楚地指出了高密度脂 蛋白 (HDL)胆固醇的血浆浓度与 CETP活性是相对的。 (Inazu, A., et. al. (2000)262(5), 2275-2282). Under physiological conditions, the net reaction is a transfer of CELP with triglycerides from apoprotein B lipoprotein to high density lipoprotein (HDL) while transporting cholesterol esters from high density lipoprotein (HDL) to apoprotein Protein B lipoprotein exchange reaction. Some studies have clearly indicated that the plasma concentration of high density lipoprotein (HDL) cholesterol is relative to CETP activity. (Inazu, A., et. al. (2000)
Cholesteryl ester transfer protein and atherosclerosis, Curr. Opin. Lipidol. 11(4).Cholesteryl ester transfer protein and atherosclerosis, Curr. Opin. Lipidol. 11(4).
389-396), 由此推断: 药学上对 CETP脂转移活性进行抑制可能会增加高密度脂 蛋白 (HDL)胆固醇水平同时降低低密度脂蛋白 (LDL)水平从而对人体有利。 389-396), it is concluded that inhibition of CETP lipid transfer activity in pharmacy may increase high-density lipoprotein (HDL) cholesterol levels while lowering low-density lipoprotein (LDL) levels, which is beneficial to the human body.
CETP抑制剂的临床试验结果显示, 人体可以利用这种机制提高循环高密度 脂蛋白 (HDL)胆固醇水平。 一项研究表明, 以每天 900毫克的剂量使用 CETP抑 制剂, 4周后高密度脂蛋白 (HDL)胆固醇增加了 34% (Circulation, 2002, 105:2159)。 在另一个 CETP抑制剂的研究中,采用了每次 120毫克每天 2次这一最高剂量给 药, 4 周后高密度脂蛋白 (HDL)胆固醇提高了 106 % (N. Engl. J. Med., 2004, 350:1505-15)。通过抑制 CETP活性来提高血浆中高密度脂蛋白 (HDL)胆固醇水平 这一方式可能会给人们带来抗动脉粥样硬化这一福音。 尽管在兔子体内显示 CETP 抑制剂具有抗动脉粥样硬化的作用, 但是这点在人体中.尚未得到证实 (Nature 2000, 406: 203-2071)。 Clinical trials of CETP inhibitors have shown that the body can use this mechanism to increase circulating high-density lipoprotein (HDL) cholesterol levels. One study showed that using CETP inhibitors at a dose of 900 mg per day increased HDL cholesterol by 34% after 4 weeks (Circulation, 2002, 105: 2159). In another study of CETP inhibitors, the highest dose was administered twice a day at 120 mg twice daily, and high-density lipoprotein (HDL) cholesterol was increased by 106% after 4 weeks (N. Engl. J. Med. , 2004, 350: 1505-15). Increasing high-density lipoprotein (HDL) cholesterol levels in plasma by inhibiting CETP activity may give people the anti-atherosclerosis. Although CETP inhibitors have been shown to have anti-atherosclerotic effects in rabbits, this has not been confirmed in humans (Nature 2000, 406: 203-2071).
一些制药公司一直在研究抑制 CETP的新化合物,然而目前没有 CETP抑制 剂上市。需要找到更安全有效的新型药物化合物, 通过单一用药或与其他药物联 用来治疗脂类疾病。基于此, 本发明描述了一系列五元及六元环氨基甲酸酯类衍 生物的制备方法及其在医药上的应用, 尤其是作为 CETP 抑制剂在医药上的应 用。 发明内容 Some pharmaceutical companies have been investigating new compounds that inhibit CETP, but no CETP inhibitors are currently available. There is a need to find new safer and more effective pharmaceutical compounds that can be used to treat lipid diseases through a single use or in combination with other drugs. Based on this, the present invention describes a process for the preparation of a series of five- and six-membered cyclic carbamate derivatives and their use in medicine, especially as a pharmaceutical application for CETP inhibitors.
