  • the present invention belongs to the field of medical technology, and more specifically, relates to a class of antihistamine compounds, their preparation methods and their use in the medical field.
  • H1 receptor antagonists are the main drugs used in the clinical treatment of allergic diseases. Structure-activity relationship studies show that H 1 receptor antagonists generally consist of an aromatic ring region, a connecting segment and a basic amine region. According to their structural types, they can be roughly divided into ethylenediamines, aminoalkyl ethers, propylamines and tricyclic drugs. During the clinical application of H 1 receptor antagonists, the main adverse reactions focus on central depression and cardiotoxicity.
  • H1 receptor antagonist molecules have high fat solubility and easily penetrate the blood-cerebrospinal fluid barrier, thereby causing sedation and hypnosis.

  • desloratadine Although many tricyclic antihistamine derivatives have been synthesized, including the highly active desloratadine. But as research deepens, its side effects gradually become apparent. At lower concentrations, desloratadine's affinity for M-type choline receptors is similar to that of histamine H receptors, so symptoms such as fatigue, dry mouth, dizziness, and headaches may inevitably occur. Sedation may also occur in patients with brain barrier resistance. In addition, desloratadine has a certain inhibitory effect on potassium channels at high concentrations, which may also have an impact on the cardiovascular system. Therefore, it is of great research value to modify the structure of desloratadine and screen out new drugs with stronger antihistamine activity, better physical and chemical properties, and better stability.

Description

抗组胺类化合物及其制备方法和用途
本申请要求于2022年07月21日提交中国专利局、申请号为202210874033.3、发明名称为“抗组胺类化合物及其制备方法和用途”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明属于医药技术领域,更确切地说,涉及一类抗组胺化合物、其制备方法和在医药领域的用途。
背景技术
过敏性疾病是影响人类健康的主要疾病,开发并获得药效更强、不良反应更低的抗过敏药物一直是全世界药物工作者的研究重点之一。H1受体拮抗剂是临床治疗过敏性疾病的主要药物。构效关系研究表明:H1受体拮抗剂一般由芳环区、连接段与碱性胺区域构成。根据其结构类型可大致分为乙二胺类、氨烷基醚类、丙胺类和三环类药物。H1受体拮抗剂在临床应用的过程中主要不良反应集中在中枢抑制以及心脏毒性这两个方面。前者是因为H1受体拮抗剂分子的脂溶性较高,容易透过血脑脊液屏障从而引起镇静催眠作用。后者是因为某些H1受体拮抗剂可以抑制人心肌细胞上的延迟整流钾电流钾离子通道,导致心电图QT间期延长,同时诱发尖端扭转型室性心动过速(torsadesde pointes,TdP),引发致命性心律失常。其中H1受体拮抗剂阿司咪唑与特非拉定由于心脏毒性的问题已经撤出市场。
尽管许多三环类抗组胺衍生物已被合成,其中包括活性很好的地氯雷他定。但随着研究的深入,其副作用逐渐显现出来。在较低浓度下,地氯雷他定对M型胆碱受体的亲和力与组胺H受体类似,因此不可避免地可能出现疲劳、口干、眩晕、头痛等症状,同时其对缺乏血脑屏障抵抗力的患者也可能引起镇静作用。另外,地氯雷他定在高浓度下对钾通道有一定的抑制作用,由此也可能对心血管***产生影响。因此对地氯雷他定进行结构修饰进而筛选出抗组胺活性更强、理化性质更优,稳定性更好的新药具有重要的研究价值。
