Definitions

  • the application belongs to the field of medicinal chemistry, and specifically relates to a piperidine derivative and its pharmaceutical composition, preparation method and application.
  • opioid analgesics and non-steroidal anti-inflammatory drugs dominate the pain treatment market, and are widely used in surgical analgesia, advanced cancer analgesia and long-term chronic pain, etc. field.
  • Opioid analgesics are the main treatment drugs for moderate to severe pain in clinic because of their fast onset of action and strong analgesic effect.
  • KOP receptor agonists and DOP receptor agonists although not having the side effects mediated by MOP receptor agonists, each have some side effects of their own.
  • KOP receptor agonists can mediate side effects such as dysphoria, sedation, and polyuria, but they have also been found to reduce the rewarding effects of addictive drugs, so they have the potential to be developed as analgesics to overcome opioid dependence.
  • DOP receptor After the DOP receptor is activated by the agonist, it will produce a twitching effect, but it also shows that it has a good analgesic effect on chronic pain.
  • the DOP receptor will not produce physiological dependence after being activated, abuse dependence less sexual. And also has anxiolytic and antidepressant effects.
  • selective KOP receptor or DOP receptor ligand compounds have not been successful in clinical development due to their limited analgesic efficacy.
  • NOP receptors The analgesic effect mediated by NOP receptors is more complex than that of other opioid receptor family members.
  • the nociceptin/orphanin FQ-NOP receptor system not only inhibits the analgesic effect mediated by opioid receptors, but also reduces Hyperalgesia to mediate analgesic effects.
  • NOP receptor agonists have the effect of analgesia and regulating the addiction caused by MOP agonists.
  • RO 64-6198 is the first reported small-molecule NOP receptor selective agonist, developed by Roche, and has shown good analgesic effects in non-human primate models and rodent model experiments, and Does not have classic opioid-mediated side effects.
  • BU08028 is an analogue of buprenorphine. This molecule has high affinity for four typical opioid receptors. The results of in vitro experiments show that BU08028 is a partial agonist of MOP/NOP receptors. Compared with buprenorphine and remifentanil, BU08028 has higher biological activity on NOP receptors; in non-human primate experiments, compared with buprenorphine and remifentanil, BU08028 showed very high analgesic and anxiolytic activity effect, is less addictive and more importantly does not show significant physiological dependence.
  • Nalorphine is a kind of bifunctional opioid drug of MOP receptor antagonist and KOP receptor agonist, which can inhibit the effect of morphine in vivo, and itself can show analgesic activity.
  • Bifunctional molecules with high activity on KOP receptors and low or moderate activity on MOP receptors are less addictive than pure MOP receptor agonists, but they have their own dysphoric and carcinogenic effects. Phantom side effects.
  • Cebranopadol is a bifunctional agonist of MOP/NOP receptors. Preclinical data show that Cebranopadol also has partial agonistic activity on KOP receptors. Cebranopadol has recently been reported to exhibit reduced tolerability, physiological dependence, and respiratory depression compared to morphine.
  • Patent WO2017/096323 discloses AT-121, which is a class of piperidinyl spirocyclic compounds, has high affinity for both MOP receptors and NOP receptors, and is a partial agonist of these two receptors. In the experiment, this molecule showed better analgesic and anti-compulsory effects, and no side effects such as respiratory depression, opioid-induced hypersensitivity and drug dependence.
  • the application provides a piperidine derivative and its pharmaceutical composition, preparation method and application.
  • This type of compound has novel structure, high affinity and agonistic biological activity of MOP receptor, NOP receptor (ORL-1 receptor) and (or) KOP receptor, and has bifunctional effects on MOP receptor and KOP receptor High selectivity for MOP receptors and NOP receptors (ORL-1 receptors), or high selectivity for bifunctional effects on MOP receptors and NOP receptors (ORL-1 receptors), and some compounds have high G protein bias, so they have unique pharmacological mechanisms.

技术领域
本申请属于药物化学领域,具体涉及一种哌啶衍生物及其药物组合物、制备方法和用途。
背景技术
疼痛是人们日常生活中最常见的生理感受,影响的病人数量甚至超过糖尿病、心血管疾病和肿瘤病人的总和。疼痛的发病机制多样,几乎伴随所有的疾病。临床上对于抗炎镇痛的需求巨大,目前阿片类镇痛药和非甾体抗炎药(NSAIDs)主宰着疼痛治疗市场,广泛应用在外科手术镇痛,晚期癌症镇痛和长期慢性疼痛等领域。阿片类镇痛药物由于其具有起效快,镇痛效果强等特点,是临床上中重度疼痛的主要治疗药物。但其成瘾性、呼吸抑制、便秘、耐受性和瘙痒等副作用限制了其使用,也带来了药物依赖、滥用致死等社会问题。研究开发一种安全有效,无副作用的镇痛药物是一项非常紧迫的社会需求。
多年来科学家们一直努力寻找可供临床选择的新型镇痛剂,既具有阿片类药物镇痛效果,又不具有其副作用。药物学家们采用了多种策略来开发安全有效的药物用以治疗疼痛和阿片成瘾。许多新的靶点机制被发现,并应用于新型镇痛剂的研发。大量研究表明,μ受体激动剂镇痛作用是通过激活G i信号,而成瘾性、呼吸抑制和便秘等副作用是通过下游β-arrestin信号通路调节。因此G蛋白偏向性μ阿片受体激动剂是近年来该领域研究的重要方向。μ受体的偏向性激动剂,选择性激活G i通路,而不影响β-arrestin信号通路, 为开发理想的阿片药物提供了可能性。
在WO2017/161017中公开了一类G蛋白偏向性MOP受体激动剂苯并咪唑酮基哌啶化合物,该类化合物在啮齿类动物镇痛模型中表现出较好的镇痛活性,且相关的副作用小于吗啡。然而该化合物本身可能在成药性方面存在缺陷,没有进一步的进入临床研究的报道。
选择性的KOP受体激动剂和DOP受体激动剂,虽然没有MOP受体激动剂介导的副作用,但它们各自有其自身的一些副作用。KOP受体激动剂会介导产生烦躁不安、镇静、多尿等副作用,但也发现其能够减少成瘾性药物的奖赏效应,因此具有开发成为克服阿片药物依赖性镇痛剂的潜力。DOP受体被激动剂激活后会产生抽搐效应,但也显示对于慢性疼痛具有较好的镇痛效果,相对于MOP受体激动剂,DOP受体被激动后不会产生生理依赖性,滥用依赖性更小。并且还具有抗焦虑和抗抑郁的效应。然而,到目前为止,选择性的KOP受体或DOP受体的配体化合物在临床开发中都因其镇痛药效有限而未见成功。
由NOP受体介导的镇痛效应要比其它阿片受体家族成员复杂的多,痛敏肽/孤啡肽FQ-NOP受体系统既抑制阿片受体介导的镇痛效应,又通过降低痛觉过敏来介导镇痛效应。研究表明,NOP受体激动剂具有镇痛和调节MOP激动剂引起的成瘾性的作用,在非人灵长动物试验中发现,选择性的NOP激动剂不会产生呼吸抑制和潜在成瘾性。RO 64-6198是报道的第一个小分子NOP受体选择性激动剂,由罗氏公司研发,在非人灵长类动物模型和啮齿类动物模型实验中表现出了良好的镇痛效应,并且不具有经典的阿片类药物介导的副作用。先灵公司在WO01/07050中公开了一类哌啶基衍生化合物,作为NOP受体(ORL-1受体)激动剂,被用作治疗咳嗽。由于痛敏肽/孤啡肽FQ受体与经典的阿片受体间存在着紧密的相互作用功能,近年来人们的注意力逐渐转移到同时作用于双靶点配体化合物的研究。
BU08028是丁丙诺啡的类似物,这一分子对于四种典型的阿片受体都具有较高的亲和力,体外的实验结果显示,BU08028是MOP/NOP受体的部分激动剂,与丁丙诺啡比较,BU08028对于NOP受体的生物活性更高;在非人灵长类动物体内实验中,与丁丙诺啡和瑞芬太尼比较,BU08028显示出了 非常高的镇痛和抗焦虑的效应,而成瘾性更低,更重要的是没有显示出明显的生理依赖性。纳络啡是一类MOP受体的拮抗剂和KOP受体的激动剂的双功能作用的阿片类药物,其在体内能够抑制吗啡产生的效应,并且自身能够显示出镇痛的活性。对KOP受体有高活性而对MOP受体具有较低或中等活性的双功能分子相对于单纯的MOP受体激动剂具有较低的成瘾性,但其自身却有令患者烦躁不安和致幻的副作用。Cebranopadol是一个MOP/NOP受体的双功能激动剂。临床前的数据显示Cebranopadol对于KOP受体也具有部分激动的活性。最近有报道与吗啡相比Cebranopadol显示出了减小耐受性、生理依赖性和呼吸抑制的效应。专利WO2017/096323公开了AT-121,是一类哌啶基螺环化合物,对MOP受体和NOP受体都具有高亲和力,是这两种受体的部分激动剂,在非人灵长动物实验中这一分子显示出了较好的镇痛和抑制强制效应的药效,并且没有呼吸抑制、阿片药物诱导的超敏效应和药物依赖性等副作用。
从已有的报道可以看到,不同的阿片受体具有自身的药理学功能特点,对阿片受体具有双功能或多功能作用的分子呈现出了独特的药理学作用,产生良好的镇痛药效的同时,能够有效的减少吗啡等传统阿片类药物的副作用,如呼吸抑制、便秘、耐受性、成瘾性等,并且具有抗抑郁和抗焦虑的效应,对治疗酒精成瘾有潜在的有效性。但目前均处于早期的研究阶段,鲜见成功。另一方,无副作用的镇痛药物有着紧迫的社会需求。因此有必要在具有多功能或双功能阿片受体作用的新型镇痛药物的领域开展更广泛的研究。

动物体内药效学测试-福尔马林诱导的炎性疼痛模型
福尔马林诱导的炎性疼痛药效动物模型由Dubuisson与Dennis于1977年创立,通过实验的长期验证,将稀释一定倍数的福尔马林利用微量注射器注射于大鼠后足掌部皮下,可以制造出一种持续的伤害性刺激,使动物出现自发性疼痛行为反应。
实验动物:SPF级雄性SD大鼠,6-7周龄,体重范围在160~180g;在满足研究目的、科学标准前提下,使用尽可能少的动物。
实验方法:1、实验开始前所有动物在动物饲养室适应性饲养一周,使其适应环境。室温保持在22±2℃,灯光照,避免强烈的声光刺激。根据实验需要随机分组,每组6-8只,并给大鼠编号。所有测试实验在上午8点至12点之间进行,为使大鼠适应福尔马林试验环境,分别将分组大鼠放在实验测试箱(透明可视)中,每天60分钟,共3天。
2、试剂配制。将分析纯的甲醛水溶液在密封小瓶中配制成2%福尔马林溶液备用(用后放置在4℃冰箱);
3、测试化合溶液配制。溶剂体系为5%DMSO+10%Solutol+85%生理盐水,根据测试实验需求,现配成实际需要的浓度;
4、给药方式及造模。本实验给药方式为皮下注射。动物实验环境饲养至第6天开展实验,记录大鼠体重,室温,湿度,和常规控制参数。按照体重给大鼠给药,给药15min后在大鼠足背皮下注射50μl的2%福尔马林溶液造模。
5、模型的评估。福尔马林注射后,将大鼠放置于测试箱中采用电脑统计其注射福尔马林后60分钟内大鼠的运动次数(注射足的抬足、舔足次数),包括早期急性期(I期)和晚期紧张期(II期)抬足次数(I期(0-9分钟)、II期(10-60分钟)、平均累积抬足次数。
计算MPE%(Maximum Possible Effect最大可能效应以百分比记)
%MPE=(1-给药组的运动次数/阴性对照组的运动次数)x100%
数据统计与分析:
计量资料以平均值±标准误来表示,所有数据统计均采用SPSS13.0统计学软件进行,所有数据进行方差齐性检验,具有方差齐性的数据(p>0.05)进行单因素方差分析,有差异(p≤0.05)的数据进行LSD多重比较分析,以p≤0.05为具有统计学差异;方差不齐的数据(p≤0.05)进行Kruskal-wallis非参数检验,有差异(p≤0.05)的数据进行Mann-Whitney两两分析比较,以p≤0.05为具有统计学差异。采用GraphPad Prism 8.0(GraphPad Software,San Diego,Califomia USA)软件进行作图。
从时间效应曲线图(图1A)可以看到,EX3在10mg/kg给药剂量时,在0~40min时间区间内时间效应曲线与吗啡组(mor)效应曲线基本重合,随后时间效应曲线逐渐靠近模型组(model),这提示化合物EX3(10mg/kg)在0~40min时间区间内具有较好的镇痛效应,且与吗啡3mg/kg镇痛效应相当。从统计分析的最大可能镇痛效应曲线图(图1B)可以看到,与空白对照组(sham)(100±3.3%)相比,模型组显著低于其均值,最大可能效应为0±18.33%,化合物EX310mg/kg剂量组最大可能镇痛效应值为94.04±5.81%,均显著高于模型对照组(p<0.05)。以上实验结果表明,化合物EX3对于福尔马林诱导的炎性疼痛具有良好的抑制效果。
动物体内药效学测试-保留性神经损伤模型
保留性神经损伤(Spared Nerve Iniury,SNI)动物模型被开发来用于研究神经性疼痛的药理机制。该模型通过人工手术的方式建立,在手术侧可产生持续和再生的疼痛超敏反应,模拟临床神经性疼痛紊乱的典型症状。SNI模型的制作:在实验的第0天将大鼠用通入异氟烷的麻醉机麻醉,俯卧位固定于手术台上,充分暴露侧臀区,对其左后支剃除体毛并酒精擦拭消毒,使用手术剪于股骨平行坐骨神经方向剪开皮肤,钝性分离臀部肌肉、股二头肌,暴露坐骨神经干,小心分离周围粘连组织,及筋膜。直至暴露出三个分支,即胫神经,腓总神经和腓肠神经。手术组的大鼠用丝线将胫神经、腓总神经结扎,分别剪断胫神经和腓总神经,并保证腓肠神经完整,逐层缝合肌肉、表皮。手术后给每只大鼠皮下注射青霉素6万单位。放置于笼内饲养,于手术后第10天开展给药实验。主要检测指标及方法:体重,所有动物每周称一次体重并详细记录;机械痛阈测定,将动物置于特制疼痛检测多单元金属网笼内,让动物适应环境10min,待动物的梳理、探究活动结束并且适应了检测环境后,用电子弗莱毛(Von Frey Hairs,法国Bioseb公司生产)刺激大鼠SNI手术侧的后肢小指侧脚掌,持续增加压力直至大鼠出现明显的缩足反应,记录此时弗莱毛的值即为机械疼痛反应的阈值,以“克”为检测单位,重复检测2次,然后取平均值作为最终检测指标;足承重测定,SNI模型组的大鼠两只后肢足的承重重量是不平衡的,采用足支撑力测量仪(Dynamic Weight Bearing Test,BIO-DWB-DUAL,BIOSEB)测量动物两只后肢足的承重差值(左足-右足),重复测量2次,取均值作为动物两只后肢足的承重差值平衡值。机械痛阈值和足承重测试时间点为造模前、给药前和给药后1、2和4h,共5个检测点。本申请的实验,根据动物体重,及给药前机械痛阈值和足承重的基值,将大鼠随机分为5组(每组8只),分别是溶媒对照组(5%DMSO+10%Solutol HS15+85%生理盐水)、阳性对照组(加巴喷丁,100mg/kg,剂量根据加巴喷丁临床使用剂量换算)、测试化合物高中低剂量组(10、3和1mg/kg),阳性对照组采用与临床用药一致的口服给药方式,其它实验组均为腹部皮下注射给药,所有实验组均为单次给药。实验结果以机械痛阈值弗莱毛和足承重差值报告,并计算相应的镇痛率。弗莱毛相对镇痛率(%)=(检测值-对照组均值)/(SNI手术前基值-对照组均值)×100;足承重相对 镇痛率(%)=(对照组均值-检测值)/(对照组均值-SNI手术前基值)×100。使用GraphPad Prism 8.0(GraphPad Software,San Diego,California USA)软件分析数据,并作图。
从实验结果可以看到(图2中A和C),在给药后1h弗莱毛测试的结果显示化合物EX3的三个剂量都能够在一定程度上提高动物的机械痛阈值,尤其是中高剂量最为明显,与模型组比较具有极显著差异(p<0.01),测得的中高剂量组大鼠的机械痛阈值分别为7.0±0.1g和9.5±0.2g,弗莱毛相对镇痛率均值分别为12.93%和49.02%,高剂量组的镇痛效果优于阳性对照组(加巴喷丁,100mg/kg,弗莱毛相对镇痛均值为29.71%)。随着时间的推进,第2h各测试药物组大鼠的机械痛阈值均有所降低,但与模型组相比均具有极显著差异(p<0.01),化合物EX3高剂量(10mg/kg)组大鼠的机械痛阈值为8.3±0.1g,弗莱毛相对镇痛率均值为33.99%,与阳性对照组接近(阳性对照组弗莱毛相对镇痛率均值为36.26%)。
SNI模型大鼠两只后足的承重重量是不平衡的,为更进一步的验证化合物EX3对于大鼠SNI神经痛的镇痛效果,本实验测量动物两只后足的承重差值(左足-右足),取均值作为动物两只后足的承重差值平衡值。测试时间点与弗莱毛测试相同。从实验结果可以看到(图2中B和D),造模后模型组动物的足承重差值的平衡值显著增加,为59.87±1.60g(手术前为3.88±0.56g),在药物的作用下,大鼠的后足承重差值平衡值显著减小,在第1h时间点最为明显,各实验组与模型组比较均具有极显著差异(p<0.01),化合物EX3高剂量组(10mg/kg)大鼠后足承重差值平衡值为46.82±1.68g,足承重相对镇痛率均值为22.11%,与阳性对照加巴喷丁组相近(阳性对照组大鼠足承重相对镇痛率均值为20.85%)。随着时间的推进,药物的镇痛作用逐渐减弱,但与模型组相比仍然具有极显著差异性(p<0.01),在第2h时化合物EX3中低剂量组足承重相对镇痛率仍保持在10%左右,高剂量组(10mg/kg)大鼠后足承重差值平衡值为46.54±0.80g,足承重相对镇痛率均值为20.03%,仍维持在较高水平,略优于阳性对照组(足承重相对镇痛率均值为17.55%),到第4h时,化合物EX3高剂量组大鼠后足承重差值平衡值与模型组相比较仍然具有极显著差异(p<0.01),足承重相对镇痛率均值为15.38%,稍优 于阳性对照组(足承重相对镇痛率均值为14.07%)。
通过SNI神经痛模型的评估,可以看到化合物EX3能够有效抑制大鼠的神经痛,且具有较好的剂量依赖性,镇痛作用效果与药物代谢周期保持一致,在1h时药物发挥最大药效,高剂量组(10mg/kg)与阳性对照加巴喷丁(100mg/kg)相比较,具有一定的镇痛优势,且作用时间较长,到第4h仍然具有很好的镇痛效应,化合物EX3在较低剂量下即表现出了优于阳性对照加巴喷丁的镇痛效果。
以上研究结果表明,本申请所示化合物对于MOP受体和KOP受体具有双选择性,通过这种双功能作用于MOP受体和KOP受体发挥着良好的镇痛效应,尤其是对神经性疼痛的抑制远优于临床用药加巴喷丁。根据已有的众多文献的报道,这一效果,单选择性的MOP受体激动剂是达不到的。
本申请中公开的化合物,优选其中部分化合物使用上述方法进行了体内药效学的评估,结果显示本申请公开的化合物具有良好的治疗炎性疼痛和神经性疼痛的药效。通过持续观察实验过程中的现象和数据分析,本申请公开的化合物其便秘和瘙痒等副作用比阳性对照要更小。
