Definitions

  • the present invention relates to the field of medicines, and in particular to a novel aromatic compound, a preparation method thereof and use as a biologically active substance in a medicament for treating and/or preventing a depression-related disease.
  • Depression is usually referred to as a mood disorder. It is an emotional psychosis characterized by depression, sadness, despair, and depression, accompanied by symptoms such as sleep disorders, anxiety, and physical discomfort. It is a common and serious mental illness. It seriously affects the patient's ability to work, quality of life, and even life-threatening. With the intensification of various stress factors, depression has become a common disease and high incidence in modern society, and its incidence is rising rapidly year by year. According to the World Health Organization, there are about 300 million people with depression worldwide, and by 2020, it may become the second largest disease after cardiovascular and cerebrovascular diseases.
  • the pathogenesis of depression is complex, and it is related to many factors such as genetics, environment and society.
  • the pathogenesis is unclear. At present, there is no clear mechanism to be widely recognized.
  • the traditional "monoamine neurotransmitter hypothesis" indicates that low levels of neurotransmitters such as central norepinephrine (NE) or serotonin (5-HT) and dopamine (DA) or low receptor function are considered to be The main cause of depression.
  • NE central norepinephrine
  • 5-HT serotonin
  • DA dopamine
  • Antidepressants have been in the market for more than 60 years since their initial publication. According to the mechanism of action, they can be divided into two generations of antidepressants.
  • the first generation of antidepressants were mainly tricyclic antidepressants (TCAs, imipramine, clomipramine, amitriptyline, etc.) and monoamine oxidase inhibitors (MAOIs, moclobemide, etc.).
  • TCAs tricyclic antidepressants
  • MAOIs monoamine oxidase inhibitors
  • moclobemide moclobemide
  • Most second-generation antidepressants mainly act on central neurotransmitters, such as selective serotonin (5-HT) reuptake inhibitors (SSRIs, fluoxetine, paroxetine, citalopram, sertraline, fluoride). Fusamine, etc., selective norepinephrine (NE) reuptake inhibitors (NaRIs, reboxetine) 5-HT and NE reuptake inhibitors (SNRIs, venlafaxine, duloxetine, etc.), NE and specific 5-HT reuptake inhibitors (NaSSAs, mirtazapine) and the like.

  • Ketamine has been used clinically for more than 50 years as a traditional anesthetic.
  • subanesthetic doses of ketamine have rapid (several hours), significant and relatively long-lasting effects in patients with refractory depression (TRD)
  • TRD refractory depression
  • the antidepressant effect about a week
  • BTD breakthrough drug qualification
  • ketamine Although ketamine exhibits a rapid, sustained antidepressant effect, it also has its own problems that may affect its clinical use. 1. Side effects: including psychotic-like, isolated side effects and respiratory depression side effects; long-term application may cause urinary tract dysfunction or even renal failure; 2. Oral bioavailability is low, difficult to orally administered; 3. Cause euphoria, hallucinations, and Addictive. These side effects of ketamine are unacceptable when used clinically.
  • (2R,6R)-HNK has the very desirable characteristics of rapid onset of treatment of depression, but there are still many shortcomings: if the compound is not good in medicine, the metabolic properties of the mouse are not ideal, T 1/2 ⁇ 1h, the clearance is fast, the plasma exposure is not high, the antidepressant activity is weak, and the amount of the drug distributed to the central nervous system is not high, so it is difficult to directly develop into a drug.

Description

芳香类化合物及其制备方法和用途 技术领域
本发明涉及药物领域,具体而言,涉及一种新型芳香类化合物及其制备方法和作为药物中生物活性物质在治疗和/或预防抑郁相关疾病中的用途。
背景技术
抑郁症通常指的是情绪障碍,是一种以情绪低落、悲伤、绝望和沮丧等为特征,伴有睡眠障碍、焦虑及躯体不适等症状的情感性精神病,作为一种常见而严重的精神疾病,严重影响患者的工作能力、生活质量,甚至可危及生命。随着多种应激因素的加剧,抑郁症已成为现代社会的常见病、高发病,其发病率在逐年快速攀升。据世界卫生组织预测,全球抑郁症病人约3亿人,到2020年,可能成为仅次于心脑血管疾病的第二大疾病。
抑郁症发病机制复杂,与遗传、环境、社会等多种因素有关,发病机制不清楚,目前尚未有一个明确的机制得到广泛认同。传统的“单胺递质假说”表明,中枢去甲肾上腺素(NE)或5-羟色胺(5-HT)、多巴胺(DA)等神经递质的含量过低或其受体功能低下被认为是引起抑郁症的主要原因。
目前,抗抑郁主要治疗手段仍然是药物治疗为主。抗抑郁药从最初上市至今已有60余年,根据作用机制,可分为两代抗抑郁药。第一代抗抑郁药主要是三环类抗抑郁药(TCAs,丙咪嗪、氯米帕明、阿米替林等)及单胺氧化酶抑制剂(MAOIs,吗氯贝胺等)。第一代抗抑郁药虽然在抑郁症的治疗方面取得了重大突破且卓有成效,但其众多的不良反应严重限制了其临床使用。大多数第二代抗抑郁药主要作用于中枢神经递质,如选择性5-羟色胺(5-HT)再摄取抑制剂(SSRIs,氟西汀、帕罗西汀、西酞普兰、舍曲林、氟伏沙明等)、选择性去甲肾上腺素(NE)再摄取抑制剂(NaRIs,瑞波西汀)5-HT和NE再摄取抑制剂(SNRIs,文拉法辛、度洛西汀等),NE和特异性5-HT再摄取抑制剂(NaSSAs,米氮平)等。与第一代抗抑郁药相比,具有较好的药代动力学和药效动力学性质,疗效好,安全性高,服用方便,受到了医生和患者的青睐,成为了目前治疗抑郁障碍的一线用药。但这些药物同时也存在严重缺陷:1、起效慢,通常需要2-4周,甚至更长时间才能发挥出较明显的疗效;2、治疗响应率低,仅有约1/3的患者对首次治疗药物有响应,而约2/3的患者仅在尝试多种抗抑郁药后才有响应。特别是,对于有自杀倾向的严重抑郁症患者(MDD),现有所有抗抑郁药物起效缓慢(需要服药2-4周时间后才能有明显疗效)的缺陷,对有高自杀风险的患者及其不利。
氯胺酮(Ketamine)作为传统麻醉药在临床应用已有五十余年。但在后期的研究中发现(Arch Gen Psychiatry,2006;63(8):856–864),亚麻醉剂量氯胺酮对难治性抑郁症(TRD)患者具有快速(几个小时)、显著且相对持久(大约一周)的抗抑郁效果,才开始逐渐为临床所关注。目前,强生公司开发的艾氯胺酮(esketamine)处于III期临床研究,并分别在药物难治性抑郁症和伴有紧迫自杀风险的重度抑郁症方面,取得了FDA授予的突破性药物资 格(BTD)。
虽然氯胺酮表现出快速、持续的抗抑郁效果,但其自身也存在一些可能影响其临床使用的问题。1、副作用:包括精神病样、分离性副作用及呼吸抑制副作用;长期应用可能引起尿道功能紊乱甚至肾衰竭;2、口服生物利用度低,难以口服给药;3、引起欣快、幻觉,具有成瘾性。氯胺酮的这些副作用是临床普遍使用时不可接受的。
2016年5月,Zanos等发表研究成果(Nature,2016,533,481-486)表明,氯胺酮快速持续的抗抑郁效果主要是源于其代谢产物(2R,6R)-HNK,而非氯胺酮本身。目前该化合物快速抗抑郁机理仍不是很清楚,有可能是因为激动AMPAR受体而发挥抗抑郁效果。
(2R,6R)-HNK具有能够快速起效治疗抑郁症这一令人十分渴望的特点,但是仍存在许多不足:如该化合物成药性不好,小鼠代谢性质不理想,T 1/2<1h,清除快,血浆暴露量不高,抗抑郁活性比较弱,药物分布到中枢神经系统中的量不高等,因此难以直接开发成为药物。
因此,临床迫切需要起效快,疗效确切,安全性高的新型抗抑郁药物。

生物学评价
以下结合测试例进一步描述解释本发明,但这些实施例并非意味着限制本发明的范围。
测试例1、本发明化合物小鼠腹腔给药强迫游泳实验中抗抑郁活性评价
强迫游泳实验(forced-swimming test)是目前应用最广泛的在啮齿动物上评价化合物抗抑郁效果的经典方法。该实验是一种行为绝望方法(行为绝望是抑郁症的核心症状),通过将动物置于一个局限的环境中(如水中),动物在该环境中拼命挣扎试图逃跑而又无法逃脱,从而提供了一个无可回避的压迫环境,一段时间后,动物即表现出典型的“不动状态”,观察并记录实验动物不动状态的时间,可以用来评价抗抑郁化合物的作用效果。
1.1、实验目的
通过单次腹腔给药10mg/kg 1h和24h后分别进行强迫游泳实验,考察不同化合物对C57小鼠抑郁样行为的影响。
1.2、实验方案
1)动物
实验动物为6周龄C57小鼠,雄性,C57种小鼠购自上海斯莱克实验动物有限公司,体重20.45±0.19g。实验前到达中国科学院上海药物研究所动物饲养中心(动物生产许可证:SCXK9[沪]2004-0002,使用许可证:SYXK[沪]2003-0029),并在动物设施中适应3天以上,6只/笼饲养。饲养环境为室温23±0.2℃,12/12小时昼夜明暗交替。行为学测试前,动物先提前2小时移至行为测试操作间,使之适应该环境,降低其紧张感。
2)动物分组
动物分组信息及相关给药信息如表2所示。
表2.动物分组及给药信息
组别 数量(只) 给药方式 注射剂量(mg/kg) 注射体积(ml/kg)
空白对照组 10 腹腔注射 0.9%NaCl 10
氟西汀 10 腹腔注射 10 10
氯胺酮 10 腹腔注射 10 10
(2R,6R)-HNK 10 腹腔注射 10 10
本发明化合物 10 腹腔注射 10 10
3)实验步骤
供试品配制:分别精密称量各受试化合物溶于0.9%NaCl溶液中,充分混匀,配成1mg/ml溶液,待用。
在给药前24小时,小鼠放入圆柱型缸内适应水中环境10min。行为测试当天,动物给药1次,分别在行为测试前1h和24h腹腔给药。将小鼠单独放入高30厘米、直径20厘米的圆柱形玻璃缸中,缸内水深为15厘米,使动物既不能逃出玻璃缸,其脚和尾部又不接触到缸底,水温23℃-25℃。拍摄小鼠入水后的6分钟视频,由于大多数动物 在开始两分钟十分活跃,因此计算后4分钟不动时间(判定不动标准:小鼠在水中停止挣扎,不动和为保持平衡或呈漂浮状态的细小的肢体运动)。
4)测试结果
通过与空白组相比,化合物使动物强迫游泳实验不动时间减少的能力来评价化合物抗抑郁效果。待测使动物不动时间越短,抑制率越高,抗抑郁活性越强,。
抑制率 1h(%)=不动时间 (空白,1h)-不动时间 (给药,1h)/不动时间 (空白,1h)×100%
抑制率 24h(%)=不动时间 (空白,24h)-不动时间 (给药,24h)/不动时间 (空白,24h)×100%

由表3可以看出,传统抗抑郁药氟西汀在强迫游泳实验中,1小时及24小时均没有明显的抗抑郁效果,说明氟西汀不具备快速起效抗抑郁的特点,与临床结果一致。文献报道的对比化合物1在1小时及24小时对不动时间的抑制率分别仅为17.4%及10.6%,远低于本发明化合物。而本发明化合物和氯胺酮一样,在腹腔给药1小时后,便快速发挥抗抑郁效果。更为突出的是,本发明化合物1小时的抗抑郁活性(抑制率32.0%-50.9%)明显优于阳性对照药氯胺酮(抑制率29.2%),特别是本发明化合物比先导化合物(2R,6R)-HNK抗抑郁活性(抑制率31.1%)也有了大幅提高。24小时抗抑郁活性证明,本发明化合物具有持久的抗抑郁活性,且同样明显优于阳性对照药氯胺酮,比先导化合物(2R,6R)-HNK(抑制率27.4%)提高幅度更大。
总之,以上实验结果表明,本发明化合物和现有化合物相比,具有快速、持久、更强的抗抑郁活性。

实验动物为6周龄C57小鼠,雄性,C57种小鼠购自上海斯莱克实验动物有限公司,体重20.45±0.19g。实验前到达中国科学院上海药物研究所动物饲养中心(动物生产许可证:SCXK9[沪]2004-0002,使用许可证:SYXK[沪]2003-0029),并在动物设施中适应3天以上,6只/笼饲养。饲养环境为室温23±0.2℃,12/12小时昼夜明暗交替。行为学测试前,动物先提前2小时移至行为测试操作间,使之适应该环境,降低其紧张感。
2)动物分组
动物分组信息及相关给药信息如表4所示。
表4.动物分组及给药信息
组别 数量(只) 给药方式 给药剂量(mg/kg) 给药体积(ml/kg)
空白对照组 10 灌胃 0.9%NaCl 10
氟西汀 10 灌胃 20 10
氯胺酮 10 腹腔 10 10
(2R,6R)-HNK 10 灌胃 20 10
本发明化合物 10 灌胃 20 10
3)实验步骤
供试品配制:分别精密称量各受试化合物溶于0.9%NaCl溶液中,充分混匀,分别配成1mg/ml及2mg/ml溶液,待用。
在给药前24小时,小鼠放入圆柱型缸内适应水中环境10min。行为测试当天,动物给药1次,分别在行为测试前1h和24h灌胃给药。将小鼠单独放入高30厘米、直径20厘米的圆柱形玻璃缸中,缸内水深为15厘米,使动物既不能逃出玻璃缸,其脚和尾部又不接触到缸底,水温23℃-25℃。拍摄小鼠入水后的6分钟视频,由于大多数动物在开始两分钟十分活跃,因此计算后4分钟不动时间(判定不动标准:小鼠在水中停止挣扎,不动和为保持平衡或呈漂浮状态的细小的肢体运动)。
4)测试结果
通过与空白组相比,化合物使动物强迫游泳实验不动时间减少的能力来评价化合物抗抑郁效果。
抑制率 1h(%)=不动时间 (空白,1h)-不动时间 (给药,1h)/不动时间 (空白,1h)×100%
抑制率 24h(%)=不动时间 (空白,24h)-不动时间 (给药,24h)/不动时间 (空白,24h)×100%
表5.本发明化合物小鼠口服给药抗抑郁活性结果
化合物 1h抑制率(%) 24h抑制率(%)
44 27.3±1.2 22.3±2.3
46 31.2±4.7 32.3±1,5
50 34.5±3.1 35.6±3.6
51 66.9±0.3 38.6±2.1
59 28.6±1.8 36.1±1.6
64 36.5±5.3 34.5±1.0
65 23.8±0.6 32.0±2.9
氟西汀 2.2±1.2 1.8±1.3
氯胺酮(腹腔) 22.7±0.2 25.1±2.7
(2R,6R)-HNK 18.4±1.6 19.6±4.4
氯胺酮口服吸收差,口服疗效不佳,不得已临床采用注射给药。而目前临床研究用于快速抗抑郁治疗时,迫不得已采取鼻腔给药途径,给临床使用带来不便。
由表5可知,传统抗抑郁药氟西汀口服在强迫游泳实验中,和腹腔给药一样,1小时及24小时均没有显现出抗抑郁效果,说明氟西汀不具备快速起效抗抑郁的特点,这与临床结果一致。而本发明化合物在小鼠口服给药情况下,无论1h及24h均显著降低小鼠强迫游泳的不动时间,显示出快速、持久、强效的抗抑郁效果。
本发明化合物相对于阳性对照药氯胺酮和先导化合物(2R,6R)-HNK,抗抑郁活性大幅提高,具有明显优势。
本发明化合物口服有效,未来可以做成口服剂型,是本发明化合物相对氯胺酮的另一个显著优势。

作为治疗抑郁症这一中枢神经系统疾病的药物,药物分布进入CNS系统如脑组织是必须的,进入脑组织药物的量直接决定了其治疗效果。通常情况下,腹腔注射给药的吸收程度要明显优于口服给药,而从表11可以看出,本发明化合物口服10mg/kg进入脑组织的药物浓度比先导化合物2R,6R-HNK腹腔给药10mg/kg进入脑组织的药物浓度提高2倍多;另外,本发明化合物脑部药物半衰期(T1/2)比2R,6R-HNK提高一倍多;给药后10min,本发明化合物20mg/kg口服给药进入脑组织的药物浓度比先导化合物2R,6R-HNK口服给药50mg/kg进入脑组织的药物浓度显著提高2-3倍,脑部药物暴露量(AUC)也有了非常显著的提高;同时也比阳性药氯胺酮腹腔给药进入脑组织的最大药物浓度显著提高。
因此,由上表可知,本发明化合物相比于阳性药氯胺酮及先导化合物2R,6R-HNK,在脑组织分布方面更具优势,具有更好的成药性。
