Definitions

  • the invention belongs to the field of medical technology, and specifically relates to a class of compounds that can be used to lower uric acid.
  • Xanthine oxidase is an important target for drug treatment of hyperuricemia and gout. Hypoxanthine in the human body will be metabolized into xanthine, and xanthine is further metabolized into uric acid. In the process of uric acid formation, XO plays a decisive role. When the activity of XO is inhibited, hypoxanthine, xanthine and uric acid will The conversion between them will be inhibited, thereby reducing the concentration of uric acid in human serum. Therefore, inhibiting the activity of XO has become the key to inhibiting uric acid production.
  • hyperuricemia blood uric acid levels exceeding 420 ⁇ mol/L in men and 360 ⁇ mol/L in women are called hyperuricemia.
  • hyperuricemia has become the second largest metabolic disease after diabetes, seriously threatening human health.
  • Hyperuricemia is not only an important biochemical basis for gout, but is also closely related to the occurrence of hypertension, hyperlipidemia, atherosclerosis, obesity, and insulin resistance.
  • the prevalence of gout among adults in the United States was 3.9% (approximately 8.3 million people) from 2007 to 2008 (Zhu Y, Pandya BJ, Choi HK.
  • urate anion transporter 1 URAT1
  • xanthine oxidase inhibitors urate oxidase
  • URAT1 inhibitors mainly act on the urate transporter in the renal proximal tubule, inhibiting the reabsorption of uric acid and increasing its excretion, thereby reducing the concentration of uric acid in the body.
  • Drugs in this class include benzbromarone, lesinurad, and probenecid.
  • Benzbromarone is an effective uricosuric drug that has been approved for marketing in many countries, but has not been approved in the United States. Benzbromarone was withdrawn from the market in some European countries in 2003 due to severe liver toxicity.
  • benzbromarone As a first-line uric acid-lowering drug. Lesinurad was approved for marketing in the United States in 2015. Its drug instructions include a black box warning that it may cause acute renal failure and cardiovascular disease risks (possibly fatal), and its efficacy is far inferior to benzbromarone, and it needs to be combined with allopurinol. use.
  • Probenecid is recommended as a single drug for reducing urinary symptoms in the US guidelines
  • Uric acid excretion drugs are the first choice in acid treatment, but their application is limited due to multiple significant interactions with some commonly used drugs (such as nonsteroidal anti-inflammatory drugs, ⁇ -lactam drugs, heparin, etc.) .
  • Xanthine oxidase inhibitors mainly include allopurinol and febuxostat. Allopurinol has been widely used clinically since it was approved by the US FDA in 1966. Currently, this drug is still recommended as the first-line drug for the treatment of gout in most countries’ gout guidelines. However, allopurinol has poor efficacy. It only inhibits XO in the reduced state and has no effect on XO in the oxidized state. Relevant studies have shown that even if allopurinol is used at the maximum dose, the rate of subjects reaching the treatment endpoint is less than 50%. (Robert M, Douglas CA, Scott B.
  • allopurinol induces acute liver damage , allopurinol should be used with caution when treating patients with hyperuricemia combined with liver disease (Imai H, Kamei H, Onishi Y, et al. Successful living-donor liver transplantation for cholestatic liver failure induced by allopurinol:case report[J] .Transplantation Proceedings, 2015,47(9):2778-2781).
  • Other side effects of allopurinol include stomach discomfort, nausea, abdominal pain, diarrhea, leukopenia and thrombocytopenia, headache, fever, loss of appetite, weight loss, and urination Pain, hematuria, itching, and drowsiness.
  • Febuxostat is a non-purine XO inhibitor developed by Teijin Company of Japan. It can inhibit the oxidation and reduction states of XO, and its activity is significantly higher than that of allopurinol. It was launched in Europe in 2008 and in the United States in 2009. With the continuous expansion of clinical application of febuxostat, its cardiovascular adverse reactions in the treatment of hyperuricemia are increasingly reported, and due to its cardiovascular toxicity (such as the risk of sudden death), the United States The Food and Drug Administration requires the addition of a black box risk warning to its drug inserts, and will adjust the prescription information in 2019 from first-line drugs to second-line drugs.
  • Polyethylene glycol recombinant uricase is the main urate oxidase drug currently on the market and is administered via intravenous injection.

Abstract

本发明公开了一类可用于降尿酸的化合物,它为通式(I)所示的化合物或其药学上可接受的盐,它能够显著降低高尿酸血症大鼠模型的血清尿酸水平,在抗痛风药物、抗高尿酸血症药物等方面具有潜在的应用价值。

Description

可用于降尿酸的化合物 技术领域
本发明属于医药技术领域,具体涉及一类可用于降尿酸的化合物。
背景技术
黄嘌呤氧化酶(XO)是药物治疗高尿酸血症和痛风的重要靶点。人体内的次黄嘌呤会代谢成黄嘌呤,黄嘌呤再进一步代谢生成尿酸,在尿酸形成的过程中,XO起了决定性的作用,当XO的活性被抑制,次黄嘌呤、黄嘌呤及尿酸之间的转化就会被抑制,进而降低人体血清中尿酸的浓度。因此,抑制XO的活性成了抑制尿酸生成的关键。
一般情况下将男性血尿酸水平超过420μmol/L,女性超过360μmol/L称之为高尿酸血症。目前,高尿酸血症成为仅次于糖尿病的第二大代谢性疾病,严重威胁人类的健康。高尿酸血症不仅是引起痛风的重要生化基础,而且与高血压、高脂血症、动脉粥样硬化、肥胖、胰岛素抵抗的发生密切相关。根据美国国家健康与营养调查的数据,2007~2008年间,美国成年人群中痛风患病率为3.9%(约830万人)(Zhu Y,Pandya BJ,Choi HK.Prevalence of Gout and Hyperuricemia in the US General Population:The National Health and Nutrition Examination Survey 2007-2008[J].Arthritis Rheum,2011,63(10):3136-3141);Meta分析显示,中国高尿酸血症的总体患病率为13.3%,痛风为1.1%(Liu R,Han C,Wu D,et al.Prevalence of hyperuricemia and gout in mainland China from 2000to 2014:A systematic review and meta-analysis[J].Biomed Research International,2015:1-12)。在过去数十年内,由于可促进高尿酸血症的合并疾病(如高血压、肥胖、代谢综合征、2型糖尿病、慢性肾脏病)的流行,痛风的发病率也逐渐上升(Khanna D,Fitzgerald JD,Khanna PP,et al.American College of Rheumatology Guidelines for Management of Gout.Part 1:Systematic Nonpharmacologic and Pharmacologic Therapeutic Approaches to Hyperuricemia[J].Arthritis Care&Research,2012,64(10):1432-1446)。
高尿酸血症和痛风发病率的日益升高严重危害着人类健康,应及早干预和治疗。但目前上市的降尿酸药物非常有限,而且毒副作用明显、患者的依从性较差。目前,用于高尿酸血症和痛风的治疗药物主要有三大类:尿酸盐阴离子转运蛋白1(URAT1)抑制剂、黄嘌呤氧化酶抑制剂和尿酸氧化酶。
URAT1抑制剂主要作用于肾近曲小管的尿酸盐转运体,抑制尿酸的重吸收,增加其排泄,从而降低体内的尿酸浓度。该类药物包括苯溴马隆、Lesinurad和丙磺舒。苯溴马隆是一种有效的促尿酸排泄药,已在多国获批上市,但美国未批准。由于严重肝毒性,2003年苯溴马隆从欧洲一些国家撤市。由于苯溴马隆相关的肝脏相关不良事件存在种族差异,中国高尿酸血症与痛风诊疗指南(2019)推荐苯溴马隆为一线降尿酸药物。Lesinurad于2015年在美国获批上市,其药品说明书中以黑框警示其可能引发急性肾衰竭和心血管疾病的风险(可能致死),且疗效远不如苯溴马隆,需与别嘌醇联用。丙磺舒在美国指南中是单药降尿 酸治疗中促尿酸排泄药的首选,但由于其与部分常用药物(如非甾体抗炎药、β-内酰胺类药、肝素等)之间存在多重显著的相互作用,使其应用受到限制。
黄嘌呤氧化酶抑制剂主要包括别嘌醇和非布司他。别嘌醇于1966年被美国FDA批准上市以来被广泛用于临床。目前,该药仍然是大多数国家痛风指南中推荐的治疗痛风的一线用药。但是别嘌醇疗效差,只对还原态的XO有抑制作用,对氧化态的XO不起作用,有关研究表明别嘌醇即使使用到最大剂量,受试者达到治疗终点率也低于50%(Robert M,Douglas CA,Scott B.Less than half of patients treated with high-Dose allopurinol reach serum uric acid target[J].ACR/ARHP Annual Meeting,2017,Abstract Number:1120)。另外它还会引起皮疹和其它罕见但致命的副反应,包括Stevens-Johnson综合征,中毒性表皮坏死松解症,致死率约10%~30%(Bocquet H,Bagot M,Roujeau JC.Drug-induced pseudolymphoma and drug hypersensitivity syndrome(drug rash with eosinophilia and systemic symptoms:DRESS[J].Seminars in Cutaneous Medicine and Surgery,1996,15(4):250-257)。临床上曾经报道别嘌醇致急性肝损害,别嘌醇在治疗合并肝脏疾病高尿酸血症患者时应慎用(Imai H,Kamei H,Onishi Y,et al.Successful living-donor liver transplantation for cholestatic liver failure induced by allopurinol:case report[J].Transplantation Proceedings,2015,47(9):2778-2781)。别嘌醇的其他副反应包括胃部不适、恶心、腹痛、腹泻、白细胞及血小板减少、头痛、发热、食欲不振、体重下降、排尿疼痛、血尿、瘙痒和嗜睡。
非布司他为日本Teijin公司研制的非嘌呤类XO抑制剂,能抑制XO的氧化态和还原态,活性明显高于别嘌醇。2008年于欧洲上市,2009年于美国上市。随着非布司他在临床上应用的不断扩展,其治疗高尿酸血症时出现的心血管不良反应越来越多地被报道出来,并且由于其心血管毒性(如猝死的风险)导致美国食品药品监督管理局要求在其药品说明书上增加黑框风险警示,并在2019年调整处方信息,由一线用药改为二线用药。2018年3月新英格兰医学杂志发表一项6190例痛风患者的研究结果公布:研究人员发现平均治疗32个月后,非布司他和别嘌醇治疗组总体的不良心血管事件发生风险相似(HR 1.03,95%CI,0.87-1.23),但是非布司他组的全因死亡率和心血管死亡率高于别嘌呤醇组。非布司他组患者心血管死亡率增加34%(HR 1.34,95%CI,1.03-1.73),全因死亡率增加22%(HR 1.22,95%CI,1.01-1.47)。心血管死亡原因中心脏性猝死最常见,其中非布司他组83例(2.7%),别嘌醇组56例(1.8%)(William B,Kenneth G,Michael A,et al.Cardiovascular safety of febuxostat or allopurinol in patients with gout[J].The New England Journal of Medicine,2018,378:1200-1210)。此外,非布司他也可能会导致严重的胃肠道毒副作用、肾脏毒副作用、肝功能异常等。
聚乙二醇重组尿酸酶为目前主要上市的尿酸氧化酶类药物,通过静脉注射给药。FDA对此药物有多条黑框警告,在20%-40%的患者中有严重的免疫过敏性副反应。其疗效一般,只有47%的病人达到低于0.36mmol/L的治疗终点。
在过去的几十年里,高尿酸血症和痛风的治疗药物开发进度缓慢,但随着发病率的逐渐增高,治疗药 物的开发引起越来越多研究人员的关注。以黄嘌呤氧化酶为作用靶点的新药设计也已经得到广泛重视,多种化合物已经进入临床试验,但仍面临毒副作用较大等诸多问题,有待更深入的研究。因此,高效低毒的XO抑制剂具有巨大开发潜力和应用价值。
