Definitions

  • the invention relates to the field of medicinal chemistry, in particular to a nitrogen-containing heterocyclic 5-HT3 receptor modulator and a preparation method and application thereof.
  • Serotonin type 3 also known as serotonin type 3, 5-HT3 receptors are expressed in the central nervous system involved in the gag reflex, pain processing, cognition and anxiety control, and also in the gastrointestinal Gastrointestinal disorders such as irritable bowel syndrome, dyspepsia, gastroesophageal reflux disease and irritable bowel syndrome play a modulating role.
  • Irritable bowel syndrome is a persistent or intermittent functional gastrointestinal disorder characterized by abdominal pain, bloating, altered bowel habits and/or stool characteristics, lack of gastrointestinal structure, and Biochemical abnormalities. Compounds that alter the activity of certain serotonin receptors have been shown to be beneficial in the symptomatic treatment of irritable bowel syndrome (IBS).
  • 5-HT3 receptor modulators The only drug in this class of 5-HT3 receptor modulators is FDA-approved alosetron, which was withdrawn from the market shortly after its approval in 2000 because of ischemic colitis in patients with IBS . The drug was later reinstated by the FDA due to high demand from IBS patients, and alosetron tablets were approved in 2002 for limited use in patients where the medical benefits outweighed the risks. Therefore, it is of great significance to develop safe 5-HT3 receptor modulators for the treatment of IBS.
  • Carcinoids are rare, slow-growing tumors that can produce small molecule polypeptides or peptide hormones. They are the most common endocrine tumors in the gastrointestinal tract and are now classified as neuroendocrine neoplasms (NENs). ). Carcinoid syndrome is mainly controlled by somatostatin analogs (SSAs). However, for the treatment of adult patients with carcinoid syndrome diarrhea (CSD) whose disease cannot be adequately controlled by SSAs alone, targeting tryptophan hydroxylase (TPH) in carcinoid tumor cells and inhibiting excess serotonin production, can reduce the frequency of carcinoid syndrome diarrhea and significantly change the symptoms.
  • SSAs somatostatin analogs
  • TPH tryptophan hydroxylase
  • CINV chemotherapy-induced nausea and vomiting
  • Postoperative nausea and vomiting is the most common symptom after surgery, and is affected by various factors such as the type of surgery, duration of surgery, anesthetic drugs and methods, and preoperative anxiety. PONV occurs in the last 24 hours, with marked nausea before vomiting. Postoperative nausea and vomiting is also a common postoperative complication, with a reported average incidence of 20% to 30%, and even up to 70% in high-risk patients. In addition to causing severe discomfort to patients, nausea and vomiting may also cause medical complications, such as wound dehiscence, bleeding, aspiration pneumonia, and water and electrolyte disturbances. Therefore, people's attention has been paid to the prevention and treatment of PONV.
  • 5-HT3 receptor antagonists which are a drug that completely antagonizes the activity of serotonin 3 receptors, and its adverse reactions are constipation and colonic Ischemia, even life-threatening in severe cases. Therefore, the preparation of more effective, safer and better pharmacokinetic 5-HT3 receptor modulators that can meet clinical needs is the key to the treatment of various diseases including IBS, CSD, CINV and PONV.

Description

一种含氮杂环类5-HT3受体调节剂及其制备方法和用途 技术领域
本发明涉及药物化学领域,具体涉及一种含氮杂环类5-HT3受体调节剂及其制备方法和用途。
背景技术
5-羟色胺3型(又称血清素3型,5-HT3)受体在涉及呕吐反射、疼痛处理、认知和焦虑控制的中枢神经系统中表达,并且在胃肠道中也有表达,因此可对胃肠道病症(如肠易激综合征、消化不良、胃食管反流疾病和激燥性肠综合征)起到调节作用。
肠易激综合征(irritable bowel syndrome,IBS)是一种持续或间歇发作的功能性胃肠道疾病,临床表现为腹痛、腹胀、排便习惯和(或)大便性状改变、缺乏胃肠道结构和生化异常。改变某些5-羟色胺受体活性的化合物已显示出有益于肠易激综合征(irritable bowel syndrome,IBS)的症状治疗。
在这类5-HT3受体调节剂中,仅有的药物为FDA批准的阿洛司琼,2000年获批后不久,因为在IBS患者中出现缺血性结肠炎,阿洛司琼退出市场。后来因为IBS患者需求较大,FDA恢复了该药物,于2002年批准阿洛司琼片剂在限制条件下用于医疗益处超过风险的患者。因此,研发安全的5-HT3受体调节剂用于治疗IBS具有重要的意义。
类癌(carcinoid)是一种罕见的、生长缓慢的、能产生小分子多肽类或肽类激素的肿瘤,是胃肠道最常见的内分泌肿瘤,现已归属于神经内分泌肿瘤(neuroendocrine neoplasms,NENs)。类癌综合征主要采用生长抑素类似物(SSAs)控制症状。但是对于单独接受SSAs疗法无法充分控制病情的类癌综合征腹泻(CSD)成人患者的治疗,靶向类癌肿瘤细胞内的色氨酸羟化酶(TPH),抑制血清素(serotonin)的过量生产,能降低类癌综合征腹泻的频率,显著改变症状。
由化学疗法引起的恶心和呕吐(chemotherapy-induced nausea and vomiting,CINV),平均发生率为高达90%。其可能使患者抵抗力越来越差,延缓病情的改善,对病人造成负面的结果。
术后恶心呕吐(postoperative nausea and vomiting,PONV)是患者手术后最常见症状,受手术类型、手术持续的时间、麻醉药物和方法及术前焦虑等多种因素的影响,绝大多数患者在术后24小时会发生PONV,呕吐前会出现明显恶心症状。术后恶心呕吐也是常见的术后并发症,据报道它的平均发生 率为20%~30%,在高风险病人中甚至达70%。恶心呕吐除了带给患者严重的不适,也可能引起医疗方面的并发症,如伤口裂开、出血、吸人性肺炎、水电解质紊乱等。所以对PONV的防治方法日益受到人们的重视。
研究显示,调节5-HT3受体对IBS、CSD、CINV和PONV均有治疗效果。目前被批准用于治疗IBS的调节5羟色胺3受体活性的药物为5-HT3受体拮抗剂,它是一种对5-羟色胺3受体活性完全拮抗的药物,其不良反应为便秘和结肠缺血,严重时甚至威胁生命。因此,制备出能够满足临床需求的、更有效、更安全、药代动力学性能更好的5-HT3受体调节剂是治疗包括IBS、CSD、CINV和PONV在内的多种疾病的关键。
发明内容
本发明的目的在于提供一种更有效、更安全、药代动力学性能更好的5-HT3受体调节剂。

以下通过具体的试验例证明本发明的有益效果
试验例1、本发明化合物对人5-HT3受体的亲和力评价
1、试验方法
使用闪烁亲近测定(SPA)形式在放射性配体结合测定中测量化合物对人5-HT3受体的相对亲和力。将受试化合物用100%DMSO稀释至10mM,然后在96孔板中用100%DMSO以10×测定浓度梯度稀释,并进一步用测定缓冲液稀释至4×测定浓度。将受试化合物与终体积为0.2mL的10nM[9-甲基- 3H]BRL-43694(Perkin Elmer,Waltham,MA)、3μg的人5-HT3受体膜(Perkin Elmer,Waltham,MA)和0.5mg/mL SPA珠(WGA PVT,Amersham Biosciences)孵育在50mM Tris-HCl,pH 7.5、3mM MgCl 2、1Mm EDTA和10%DMSO中。通过连续地添加50μL的受试化合物或缓冲液、SPA珠、放射性配体和5-HT3受体膜,将结合反应设置在PicoPlates-96(Perkin Elmer,Waltham,MA)的孔中。室温搅拌过夜孵育后,以1500rpm离心15分钟,避光孵育30分钟。最后在TopCount微板计数器(Perkin Elmer)中读取5分钟放射活性。总结合对照为只含有化合物稀释缓冲液;非特异性结合是在存在30μM MDL-72222的情况下确定的。特异性结合是通过从总结合中减去非特异性结合来确定。所有实验是十个竞争配体浓度一式两份进行。IC 50值是使用来自IDBS Ltd的Xlfit4.1曲线拟合软件由特异性结合数据确定的。
实验数据及分析:抑制常数Ki=IC 50/(1+(L/KD)),其中L=在测定中 放射性配体的浓度,KD=放射性配体对受体的亲和力。
2、试验结果
本实验测试本发明化合物对人5-HT3受体的亲和力,实验结果如下表1所示。
表1.本发明化合物对人5-HT3受体的亲和力
Cmpd. IC 50(nmol) Ki(nmol)
1 288.3 52.23
2 1783 321.26
3 >10000 >1802
4 8955 1613.51
综上,本发明提供了一种含氮杂环类化合物及其制备方法,该化合物能够用作5-HT3受体调节剂。实验证明,本发明制备的化合物对5-HT3受体具有很强的亲和力,作为5-HT3受体的调节剂具有很高的活性,可以用于制备5-HT3受体调节剂,还可以用于制备治疗与5-HT3受体相关的疾病(如肠易激综合征、恶心、呕吐、肠胃炎、胃功能紊乱、腹泻、疼痛、类癌综合征、以及药物成瘾)的药物,具有良好的应用前景。
