  • the invention belongs to the field of medicinal chemistry, and in particular relates to a regulator containing trihecyclic derivatives, its preparation method and application.
  • Schizophrenia is a disorder characterized by deep cognitive and emotional dissociations that affect the most basic human behaviors, such as language, thought, perception, and self-awareness.
  • the symptoms of the disease include a wide range, the most common being mental disorders, such as hallucinations, paranoia and delusions.
  • mental disorders such as hallucinations, paranoia and delusions.
  • schizophrenia often has comorbidities, such as anxiety disorders, depression, or psychotropic substance abuse.
  • Typical anti-schizophrenia drugs that is, traditional anti-schizophrenia drugs, are the first-generation anti-schizophrenia drugs, which mainly exert pharmacological effects by blocking dopamine D2 receptors, including chlorpromazine, fluphenazine, etc. (Fluphenazine), Haloperidol (Haloperidol), Thiothixene (Thiothixene), Trifluoperazine (Stelazine), Perphenazine (Trilafon) and Thioridazine (Mellaril), etc. They were breakthrough in treating positive symptoms of schizophrenia but failed to treat negative symptoms and cognitive impairment.
  • Typical antischizophrenia drugs generally have severe extrapyramidal syndrome (EPS) and tardive dyskinesia (TD) side effects, and are ineffective for one-third of schizophrenia patients.
  • EPS extrapyramidal syndrome
  • TD tardive dyskinesia
  • atypical anti-schizophrenia drugs that is, new anti-schizophrenia drugs, commonly used clinically include Clozapine (Clozapine), Risperidone (Risperidone) , Olanzapine (Olanzapine), Quetiapine (Quetiapine) and Ziprasidone (Ziprasidone), etc.

  • the serotonin system plays an important role in regulating the functions of the prefrontal cortex (PFC), including emotional control, cognitive behavior and working memory.
  • Pyramidal neurons and GABA interneurons of the PFC contain several serotonin receptor subtypes 5-HT 1A and 5-HT 2A with exceptionally high densities. It has recently been demonstrated that PFC and NMDA receptor channels are targets of 5-HT 1AR , and that these two receptors modulate excitatory neurons in the cerebral cortex, thereby affecting cognitive function. Indeed, various preclinical data suggest that 5-HT 1AR may be a new therapeutic target for the development of antischizophrenia drugs.
  • 5-HT 2A played an important role in it, involving various aspects of perception, emotion regulation and motor control. Blockade of 5-HT 2A receptors modulates the function of dopamine, thereby improving the positive symptoms of schizophrenia.
  • 5-HT 2B receptors are closely related to cardiometabolic abnormalities, cardiovascular abnormalities such as pulmonary hypertension, fibrosis, and valvular disease, and 5-HT 2C receptors are closely related to weight gain.
  • D3 receptors in the brain are mainly selectively distributed in the limbic system.
  • There are two main DA neural pathways in the brain one is the nigrostriatal pathway to regulate motor function, and the other is the ventral tegmental area of the midbrain
  • the DA pathway of the nucleus accumbens prefrontal cortex is closely related to learning, cognition and emotional activities, and its dysfunction will lead to abnormal mental activities. This DA pathway is also the main pathway of reward effects in the brain.
  • D 3R is in the two DA They are distributed in neural pathways and have complex interactions with other DA receptor subtypes, which may serve as a target for antipsychotic drug treatment.
  • Selective D 3 receptor antagonists can improve the dyskinesia caused by taking L-dopamine in Parkinson's patients. Therefore, it is of great significance for clinical treatment to find an anti-schizophrenia drug with few side effects of multi-receptor binding.
  • Aripiprazole is another atypical antischizophrenia drug widely used in clinical practice. It has a partial agonistic effect on the D2 receptor, an agonistic effect on the 5-HT 1A receptor, an antagonistic effect on the 5-HT 2A receptor, and an antagonistic effect on the 5-hydroxytryptamine (5-HT) receptor (5-HT 1A , 5-HT 2A ) have a lower affinity than D 2 receptors. Due to its unique pharmacological mechanism, it is not only effective in treating the positive symptoms of schizophrenia, but also can improve the negative symptoms and cognitive impairment of patients without causing extrapyramidal syndrome, tardive dyskinesia, etc. side effect.
  • aripiprazole as a new generation of atypical antischizophrenia drug, has some advantages in curative effect, it still has many adverse reactions clinically, and more than 10% of patients will experience weight gain, headache, and dizziness. , Akathisia, insomnia and gastrointestinal discomfort and other adverse reactions, leading to the withdrawal of patients to make the condition repeated.
  • the current drugs for the negative symptoms of schizophrenia referring to the existence of defects in normal emotional responses and other thinking processes
  • the negative symptoms of some patients have been improved, but the overall effect is limited, and there are still many patients Due to negative symptoms, it is impossible to recover and restore normal social functions, making it difficult to resume normal social work.
  • the treatment of cognitive impairment is also a key point in the treatment of schizophrenia, which affects the verbal memory, semantic processing ability and attention function of most patients with schizophrenia. Functional improvements are also very limited.
  • Refractory schizophrenia refers to a group of patients who cannot obtain ideal curative effect after being treated according to general methods. This type of patients have already been treated with three kinds of anti-schizophrenia drugs with different active ingredients, but the treatment response is not good. Or the adverse reactions of anti-schizophrenia drugs cannot be tolerated, or the disease relapses or worsens even with sufficient maintenance or preventive treatment. The direction to be conquered.

技术领域
本发明属于药物化学领域,特别涉及含三并环类衍生物调节剂、其制备方法和应用。
背景技术
精神分裂症是以认知力和情感深度分裂为特征的一种疾病,表现为最基本的人类行为受到影响,例如语言、思想、知觉和自我感知等。该疾病的症状所包含的范围较广,最常见的为精神方面的障碍,比如产生幻觉、妄想症和错觉等。全球范围内约有1%的人患精神分裂症,而在所有接受治疗的患者中只有5%最终能够得以完全康复。此外,由于精神分裂症通常会引发合并症,例如焦虑障碍、抑郁或精神性药物滥用等。
用于治疗精神分裂症的药物统称为抗精神分裂症药物。典型抗精神分裂症药物,即传统抗精神分裂症药物,是第一代抗精神分裂症药物,主要通过阻断多巴胺D 2受体发挥药理作用,包括氯丙嗪(chlorpromazine)、氟奋乃静(Fluphenazine)、氟哌丁苯(Haloperidol)、氨砜噻吨(Thiothixene)、三氟拉嗪(Stelazine)、奋乃静(Trilafon)和甲硫哒嗪(Mellaril)等。它们治疗精神分裂症阳性症状有突破性,但未能治疗阴性症状和认知障碍。典型抗精神分裂症药物一般有严重的锥体束外综合征(EPS)和迟发性运动障碍(TD)的副作用,并且对三分之一的精神分裂症病人无效。
20世纪90年代引入第二代抗精神分裂症药物,称为非典型抗精神分裂症药物,即新型抗精神分裂症药物,临床上常用的包括氯氮平(Clozapine)、利哌酮(Risperidone)、奥氮平(Olanzapine)、喹硫平(Quetiapine)和齐拉西酮(Ziprasidone)等,虽然它们各自的药理作用不完全一致,但却具有共同的药理特征,即对5-羟色胺(5-HT)受体(5-HT 1A、5-HT 2A、5-HT 2B、5-HT 2C)的亲和力远比对D 2受体的要高。其临床效果与第一代抗精神分裂症药物相比有更多优势,不但对阳性症状与传统抗精神分裂症药物同样有效,而且对阴性症状、认知缺陷症状有效,作用谱更广,且能明显降低引起EPS和TD的倾向,但是这些药物仍存在QTc间隙延长,高泌乳素血症,体重增加,心脏代谢异常和心血管副作用等不良反应。因此寻找能对精神分裂症阳性、阴性症状和认知障碍有效,而且副作用小的药物是现在研究的热点。
5-羟色胺系统在调节前额叶皮层(PFC)的功能中起着重要作用,包括情绪控制,认知行为和工作记忆。PFC的锥体神经元和GABA中间神经元包含了几个具有特别高密度的5-羟色胺受体亚型5-HT 1A和5-HT 2A。最近得到证明PFC和NMDA受体通道是5-HT 1AR的目标,这两个受体调节大脑皮层兴奋性神经元,从而影响认知功能。实际上,各种临床前数据表明5-HT 1AR可能是发展抗精神分裂症药物新的治疗靶标。非典型抗精神分裂症药物(如clozapine)对5-HT 1AR的高亲和力及其低的EPS 副作用均说明5-羟色胺系统在调节前额叶皮层(PFC)的功能中起着重要作用,包括情绪控制、认知行为和工作记忆。PFC的锥体神经元和GABA中间神经元包含了几个具有特别高密度的5-羟色胺受体亚型5-HT 1A和5-HT 2A。最近研究表明5-HT 1A激动剂与非典型抗精神分裂症药物治疗相关,能改善阴性症状和认知障碍。在应用非典型抗精神分裂症药物氯氮平治疗精神分裂症时,人们发现5-HT 2A在其中起着很重要的作用,涉及到感知、情绪调节以及运动控制的各个方面。阻断5-HT 2A受体可调节多巴胺的功能,从而起到改善精神分裂症阳性症状的作用。另外,5-HT 2B受体与心脏代谢异常,肺动脉高压、纤维化和瓣膜病等心血管异常密切相关,5-HT 2C受体与体重增加密切相关。
D 3受体在脑内的分布情况主要选择性分布于边缘系统,脑内有两条主要DA神经通路,一条是黑质纹状体通路调控运动功能,另一条是中脑腹侧被盖区伏隔核前额叶皮层DA通路与学习认知和情感活动密切相关,其功能紊乱将导致精神活动的异常,该DA通路也是脑内奖赏效应(reward effects)的主要通路,D 3R在两条DA神经通路中都有分布,并和其它DA受体亚型间存在着复杂相互作用,可能作为抗精神病药物治疗的一个目标。选择性D 3受体拮抗剂能改善帕金森病人服用左旋多巴胺引起的运动障碍。因此,寻找一个多受体结合副作用小的抗精神分裂症药物对临床治疗具有重要意义。
阿立哌唑是另一个在临床上广泛使用的非典型抗精神分裂症药物。其对D 2受体具有部分激动作用,对5-HT 1A受体具有激动作用,对5-HT 2A受体具有拮抗作用,其对5-羟色胺(5-HT)受体(5-HT 1A、5-HT 2A)的亲和力比对D 2受体要低。由于其独特的药理学机制,在临床上不仅对治疗精神分裂症的阳性症状有效,且能改善病人的阴性症状和认知障碍,且不引起锥体束外综合征、迟发性运动障碍等副作用。尽管阿立哌唑作为新一代的非典型抗精神分裂症药物在疗效上具有一些优势,但其在临床上依然存在许多的不良反应,有超过10%的患者会发生包括体重增加,头痛,头晕,静坐不能,失眠和胃肠道不适等不良反应,导致患者停药使病情反复。此外,虽然目前针对精神分裂症阴性症状(指存在正常情绪反应和其他思维过程的缺陷)的药物已经应用于临床,使部分患者的阴性症状得到改善,但总体而言效果有限,仍然有许多患者因阴性症状而无法痊愈和修复正常的社交功能,导致难以恢复正常的社会劳动。另外,认知障碍治疗也是目前精神分裂症治疗的一个重点,影响大多数精神分裂症患者的言语记忆、语义处理能力和注意力功能,而目前在研或上市的抗精神分裂症药物对认知功能的改善也非常有限。
目前的抗精神分裂药物除了上述问题,难治性精神分裂症的治疗依然处于困境之中。难治性精神分裂症指按照通用方法进行治疗而不能获得理想疗效的一类患者,该类患者已经经过了三种不同活性成分的抗精神分裂症药物治疗,足量足疗程但治疗反应不佳或者无法耐受抗精神分裂症药物的不良反应,或者即便得到充分的维持或预防治疗依然病情反复或恶化,因此抗难治性精神分裂症的药物一直是当下临床药物研究的难题,也是一直亟需攻克的方向。
目前,已经完成二期临床试验,三期临床试验正在筹备中的雷维瓦(Reviva)的RP5063,是一种非典型抗精神分裂症药物,通过调节多巴胺和血清素系统的功能起到抗精神分裂症的作用。它是D 2和D 3受体的部分激动剂,5-HT 1A受体的激动剂,5-HT 2A受体的拮抗剂,对5-HT 2B、5-HT 2c和5-HT 7则表现为拮抗效应。与典型抗精神分裂症药物相比,RP5063作为一种多靶点受体调节剂对精神分裂 症的阳性症状、阴性症状和认知障碍均有一定的改善作用,同时还能降低一些不良反应发生的风险。
因此,迫切需要开发出具备良好且持续有效的阴性症状治疗效果,改善患者认知功能,能够有效治疗难治性精神分裂症,此外还需具备较低的药物不良反应(如椎体外系反应,迟发性运动障碍,高泌乳素血症,体重增加,恶心呕吐,心脏代谢异常,心血管异常等药物不良反应),且作用于多靶点的抗精神分裂症药物,以满足巨大的市场需求。
