Definitions

  • the invention belongs to the field of drug synthesis, and in particular relates to a KHK inhibitor, its preparation method and application.
  • metabolic diseases such as obesity, diabetes, fatty liver, and hyperlipidemia
  • cardiovascular diseases such as atherosclerosis, hypertension and coronary heart disease, or various diseases such as kidney and gout, which seriously endanger people's physical and mental health and social development.
  • NASH nonalcoholic steatohepatitis
  • HCC hepatocellular carcinoma
  • NAFLD not only affects the hepatobiliary system of patients, but is also closely related to insulin resistance, blood lipid disorders, atherosclerosis, fat embolism, and blood system diseases. NASH is currently the second leading cause of liver transplantation in the United States, and there are currently no approved drugs for the treatment of NASH.
  • fructose can also synthesize endogenous fructose through the polyol pathway.
  • glucose is converted into fructose through the intermediate sorbitol through the polyol pathway to produce endogenous fructose.
  • the endogenous pathway of fructose polyols is used in high blood sugar, inflammatory and other pathological environments, such as acute kidney injury , the activity of this pathway is significantly increased, and the increase of endogenous fructose may be related to the pathogenesis of diabetic nephropathy, gout and other diseases.
  • fructokinase is not regulated by negative feedback from the substrate. Therefore, the fructose taken up by cells can be quickly phosphorylated, and in the case of excessive fructose intake, the rapid phosphorylation of fructose can consume a large amount of ATP and phosphoric acid.
  • the reduction of phosphate groups will stimulate AMP deaminase (AMP deaminase, AMPD), catalyze the degradation of AMP into inosine acid, and increase the degradation rate of purine.
  • hypoxanthine is oxidized to xanthine and finally converted to uric acid.
  • xanthine oxidoreductase xanthine dehydrogenase and xanthine oxidase
  • hypoxanthine is oxidized to xanthine and finally converted to uric acid.
  • humans are born with a lack of uricase, so excessive fructose intake promotes uric acid production, which can lead to elevated blood uric acid levels.
  • Ketohexokinase also known as fructokinase (Fructose kinase, FK), is a key enzyme in fructose metabolism. With the assistance of ATP (adenosine triphosphate), KHK enzyme in the liver phosphorylates the C 1 position of fructose to produce fructose-1-phosphate (FlP), which enters the normal metabolic pathway; at the same time, uric acid is produced downstream of ATP.
  • Human ketohexokinase (hKHK) expressed by two alternative mRNA splices encodes two distinct regioisomers KHK-A and KHK-C.
  • KHK-C has a lower Km value, a higher Kcat, and a catalytic efficiency higher than 405 times, indicating that KHK-C has significantly higher affinity and ability to phosphorylate fructose than KHK-A.
  • KHK-A is widely expressed and KHK-C is distributed in the liver, kidney, and intestine, KHK-C is the main metabolic site of fructose in the body.
  • KHK is the rate-limiting enzyme that metabolizes fructose to fructose-1-phosphate and is an important target for regulating fructose metabolism.
  • Fructose is the only common carbohydrate that produces uric acid during its metabolism, and fructose also stimulates the synthesis of uric acid from amino acid precursors.
  • Inhibition of KHK may therefore be effective in inhibiting fructose metabolism and the resulting accumulation, oxidative stress, inflammation and insulin resistance, and thus for NASH and gout, and for changes involving either or both endogenous or ingested fructose It is beneficial for many diseases.
  • the object of the present invention is to provide a kind of KHK inhibitor, its preparation method and application.

Description

一种KHK抑制剂,其制备方法和应用 技术领域
本发明属于药物合成领域,具体涉及一种KHK抑制剂,其制备方法和应用。
背景技术
肥胖、糖尿病、脂肪肝、高血脂等代谢性疾病的患病率在全球呈现快速上升趋势。这些代谢性疾病可进一步发展为动脉粥样硬化、高血压和冠心病等心血管疾病或肾脏、痛风等多种疾病,严重危害人们的身心健康和社会发展。
大量的流行病学资料和实验研究表明,果糖(fructose)摄入过量和代谢合成异常可能是代谢性疾病发病率升高的重要因素。高果糖玉米糖浆的广泛应用,大大增加了现代人对果糖的摄入。过量果糖摄入可引起内脏脂肪积聚,导致肥胖、高血脂、高血压、胰岛素抵抗和高尿酸血症,引起糖尿病、脂肪肝、痛风和急慢性肾脏疾病等代谢性疾病。其中,最为大家关注的是非酒精性脂肪性肝病NAFLD/(非酒精性脂肪肝炎)NASH。
最近的研究发现高果糖饮食是造成NASH的重要原因。很多食物,包括天然水果中均含有丰富的果糖。由于饮料和加工食品中糖添加(通常是蔗糖和高果糖玉米糖浆)不断增加,导致现代人饮食中果糖的含量增加。高果糖摄入已被证明会引起许多不良代谢作用,它在肥胖和代谢综合征的发展中具有一定的作用,如体重增加,高脂血症,高血压和胰岛素抵抗。果糖促进了NAFLD的发生、发展,加剧了NAFLD的发展和恶化。同时,高果糖摄入会增加NASH和进展期肝纤维化的风险。饮食习惯和生活方式的西化导致NAFLD的发病率显著增加,流行病学研究发现,约10~20%NAFLD患者会发展为非酒精性脂肪肝炎(nonalcoholic steatohepatitis,NASH),这是单纯性脂肪肝进一步发展的结果,其病理表现为脂质沉积、炎性细胞浸润、肝组织坏死和纤维化病变。世界范围内,NASH在普通人群的发病率在5~7%,在糖尿病人群中,发病率显著升高到22%。NASH患者中有15~25%会进一步病变为更严重的肝硬化和肝细胞癌(HCC)。NAFLD不仅会影响患者的肝胆系统,还与胰岛素抵抗、血脂紊乱、动脉粥样硬化、脂肪栓塞、血液系统疾病等密切相关。NASH目前是美国肝移植的第二大病因,目前尚无任何获准的治疗NASH的药物。
除了食物中摄入的外源性果糖外,果糖还可以通过多元醇途径合成内源性果糖。在人体内,葡萄糖通过多元醇通路经过中间体山梨糖醇转化为果糖,产生内源性果糖,研究发现,果糖多元醇内生途径在高血糖,存在炎性等病理环境下,如急性肾损伤,此通路的活性显著增加,内源性果糖的升高可能跟糖尿病肾病,痛风等多种疾病的发病有关系。
虽然,果糖与葡萄糖的分子量完全相同,但二者的体内代谢路径存在很大差 别。与葡萄糖激酶不同的是,果糖激酶不受底物的负反馈调节。因此,细胞摄取的果糖能被快速磷酸化,在果糖摄入过多的情况下,果糖的快速磷酸化可消耗大量ATP和磷酸。磷酸基团的减少会刺激AMP脱氨酶(AMP deaminase,AMPD),催化AMP降解为次黄苷酸,提高嘌呤降解率。在黄嘌呤氧化还原酶(黄嘌呤脱氢酶和黄嘌呤氧化酶)的作用下,次黄嘌呤被氧化为黄嘌呤,最终转变为尿酸。和啮齿类动物不同,人先天缺乏尿酸酶,因此果糖摄入过量促进尿酸生成,可导致血尿酸水平升高。
己酮糖激酶(ketohexokinase,KHK),又称果糖激酶(Fructose kinase,FK)为果糖代谢的关键酶。肝脏中KHK酶在ATP(三磷酸腺苷)的协助下磷酸化果糖Cl位,产生果糖-1-磷酸(FlP),进入正常代谢路径;同时ATP下游产生尿酸。两个替代性mRNA剪切体表达的人源性己酮糖激酶(hKHK)编码两个不同区域异构体酶KHK-A和KHK-C。KHK-C具有更低的Km值,更高的Kcat,高于405倍的催化效率,说明KHK-C对果糖磷酸化的亲和力和能力明显比KHK-A高。虽然KHK-A表达广泛,KHK-C分布于肝脏、肾脏、肠,但是KHK-C是体内果糖的主要代谢位点。
KHK是果糖代谢为果糖-1-磷酸的限速酶,是调节果糖代谢的重要靶点,研究表明敲除果糖代谢的关键基因KHK小鼠被保护免受葡萄糖诱导的体重增加、胰岛素抗性及脂肪变性,表明在高血糖病况下,内源性产生的果糖可促成胰岛素抗性及脂肪变性。果糖是唯一在其代谢过程中产生尿酸的常见碳水化合物,同时果糖还会刺激氨基酸前体合成尿酸。因此抑制KHK可以有效地抑制果糖代谢及造成的直至堆积、氧化应激、炎症和胰岛素抵抗,从而对于NASH和痛风,以及对其中涉及内源性或摄入果糖中的任一或两者的改变的许多疾病均有益处。
