- Psychotic patients will have positive symptoms such as delusions, hallucinations, disordered thoughts, language and behavior, negative symptoms such as lack of emotions and expressions, poor speech, lack of pleasure, and cognitive impairment.
- antipsychotics first generation
- second generation clozapine, risperidone, olanzapine, aripiprazole, etc.

Abstract
一种吗啉杂环类化合物的盐及其制备方法和应用。具体涉及一种具有通式(V)所示化合物的盐及晶型、制备方法和含有治疗有效量的该盐的药物组合物,及其用于制备治疗、预防或控制神经障碍的药物用途。
Description
本发明属于医药生物领域,具体涉及一种吗啉杂环类化合物的盐、晶型及其制备方法和应用。
精神分裂症是患病率最高的一种精神病,病程缓慢,容易反复发作、加重或恶化,对患者及患者家属所造成了严重的疾病负担和不良后果。精神病患者会出现妄想,幻觉,思想语言和行为紊乱等阳性症状,无情绪和表情,言语贫乏,缺乏愉悦感等阴性症状以及认知障碍等症状。虽然在过去的几十年中,抗精神分裂症药物的研发和临床应用有了很大发展,但传统抗精神病药(一代)(氟哌啶醇,氟哌利多,甲硫哒嗪等)及非典型抗精神病药(二代)(氯氮平,利培酮,奥氮平,阿立哌唑等)都是针对D2和5-HT2A靶点机制的,对阳性症状治疗效果较好,对阴性症状和认知障碍改善效果不理想,且具有锥体外束和体重增加等副作用。抗精神分裂药物也有很多非D2/5-HT2A受体研究,包括GlyT1 D1,D4,D3,NMDA,mGluR2/3,AMPA 5-HT2C,烟碱a7,毒蕈碱的M1/M4,H3,NK-3等。尽管这些靶点在临床前模型中有很好的疗效,但大多数新的非D2/5-HT2A机制药物在临床试验中显示疗效有限或没有成功。所以急需开发不仅能够改善阳性症状,也能改善阴性症状和认知障碍且无锥体外系副作用的抗精神分裂症的新靶点药物。
痕量胺(trace amines,TAs)在哺乳动物脑内浓度很低,在很多精神疾病(精神分裂症、抑郁症、焦虑症、帕金森病/注意缺陷多动障碍)中,痕量胺的含量发生改变。TAAR1受体是TA1受体一种亚型,属于G蛋白偶联受体,主要表达在外周器官和细胞(如胃、小肠、十二指肠,和白细胞)和中枢神经系统(CNS)星形胶质细胞以及单胺神经元的轴突末梢突触前膜内,具有调节DA、5-HT和谷氨酸能活动的功能。
5-HT1A受体是G蛋白耦联受体家族成员,是5-HT受体的一种亚型,在中枢及外周均有分布,与精神、情绪、学习与记忆等密切相关,精神分裂症患者额叶和颞叶皮质5-HT1A受体密度增加,5-HT1A受体激活可以改善精神分裂症的阴性症状,研究发现也与改善阳性症状有关。
现已公开国际申请的WO-2011069063A2为TAAR1受体激动剂、5-HT1A受体部分激动剂的SEP-363856,用于治疗精神分裂症,临床二期试验结果良好,对阳性症状和阴性症状均有疗效、安全性好,目前已进入临床三期研究。目前急需开发具有对阳性症状和阴性症状均有疗效且安全性好的新颖性靶点的药物用于治疗精神分裂症,以满足巨大的市场需求。
PCT/CN2022/129881中公开了一系列2-(芳基-2-基)吗啉及其氘代衍生物的结构,在后续的研发中,为了产物易于处理、过滤和干燥,寻求适合的便于储存、产品长期稳定的晶体,本发明对上述化合物的盐型及晶型进行了全面的研究。
