Abstract
本发明涉及新颖的通式A的4‑吡嗪‑2‑基甲基‑吗啉,其制备方法、含有其的药物组合物,以及其在疗法中,尤其在治疗或预防与NR2B负向立体异位调节性质相关病况中的用途。
Description
本发明涉及新颖的通式A的4-吡嗪-2-基甲基-吗啉
其制备方法、含有其的药物组合物以及其在疗法中,尤其在治疗或预防与NR2B负向立体异位调节特性相关的病况中的用途。
根据通式A的本发明化合物展示NR2B负向立体异位调节特性。
过去二十年的广泛研究已表明,N-甲基-D-天冬氨酸盐受体(NMDA)在阿尔茨海默症(Alzheimer's disease)、帕金森氏病(Parkinson's disease)、运动困难症、中风、运动神经性疾病、精神病、癫痫症、焦虑、精神分裂症及疼痛中发挥相关作用。
非选择性NMDA受体拮抗剂氯胺酮(外消旋以及S对映异构体),一种主要用于开始及保持麻醉的药物,在过去几年里已证实在以亚麻醉剂量治疗重度抑郁症(MDD)方面的临床功效(Murrough等人,2013,Am J Psychiatry.170:1134;Singh等人,2016,BiolPsychiatry.80:424)。更确切而言,氯胺酮使功效快速起效,该功效在未充分对标准药物疗法作出反应的MDD患者中持续数天(Berman等人,2000.Biol Psychiatry 47:351,Serafini等人,2014.Curr.Neuropharmacol.12:444)。然而,非选择性NMDA受体拮抗剂具有一定范围的限制其应用的非所要作用。详言的,分裂性及精神性副作用对于诸如氯胺酮的非选择性NMDA受体拮抗剂突出(Krystal等人,1994.Arch.Gen.Psychiatry 51:199)。在1990年代早期,发现存在多种NMDA受体亚型,其含有不同NR2(A-D)次单元(Paoletti等人,2013 NatRev.Neurosci 14:383)。近年来,NR2B亚型选择性NMDA受体负向立体异位调节剂(NR2BNAM)引起了人们的兴趣且已展示出在大范围临床适应症(诸如注意力、情绪、情感及疼痛)中的潜能,以及涉及许多不同的人类病症(Mony等人,2009.Br.J.Pharmacol.157:1301;Chaffey等人,Current Anaesthesia&Critical Care 19,183)。详言的,NR2B NAM亦已证实在早期临床试验中的抗抑郁功效(Preskorn等人,2008.J Clin Psychopharmacol 70:58)。使用NR2B NAM以及应用各种转殖基因小鼠菌株的临床前研究已展示出,含有NR2B的NMDA-受体调节氯胺酮在(例如)强迫游泳实验中的积极作用(Miller等人,2014eLife 3:e03581;Kiselycznyk等人,2015,Behav Brain Res,287:89)。此外,归因于极大减弱的分裂性及拟精神病的副作用,选择性NR2B NAM具有优于非选择性NMDA受体拮抗剂(诸如氯胺酮)的优点(Jimenez-Sanchez等人,2014.Neuropsychopharmacology 39:2673)。迄今为止所描述的NR2B NAM已显现出关于其受体药理学及/或关于在人类药物疗法中的潜在用途受限的其他药物特性的缺点(Taylor等人,2006,Clin Pharmacokinet.45:989;Addy等人,2009 J ofClinical Pharmacology 49:856)。
WO2015/130905公开式(I)化合物
其为用于治疗多发性硬化症、多神经炎、多发性神经炎、肌肉萎缩性侧索硬化症、阿尔茨海默症或帕金森氏病的Nav1.6的抑制剂。WO2015/130905公开特定实施例100、105、106及107,其中环B对应于间二取代苯环。
WO2015/130905报导特定实施例100、105、106及107为较弱的Nav1.6抑制剂(实施例100、105及107在1-5μM处的Nav 1.6堵塞,及实施例106在>5μM处的Nav 1.6堵塞)。
本发明的化合物一般涵盖WO2015/130905的式(I)。本发明的化合物在结构上不同于WO2015/130905中明确公开的实施例100、105、106及107,因为其含有代替间二取代苯环的对二取代吡嗪基次结构。
结构差异出乎意料地产生强力NR2B负向立体异位调节剂(参见表1),而WO2015/130905的特定实施例100、105、106及107并不展示NR1-NR2B离子通道上的任何活性(参见表2)。此外,本发明的化合物在WO2015/130905的特定实施例100及105抑制Nav 1.6的浓度处并不抑制Nav 1.6(5μM;参见表3及表4)。
此外,本发明的化合物展示良好膜渗透性且无活体外流出(参见表5的MDCK分析MDR1(P-gp))。因此,预期本发明的化合物展示灵验的CNS药物所需的有利的脑穿透。
MDCK分析提供关于化合物穿过血脑屏障的潜能的信息。横跨可渗透过滤器支撑体上所生长的偏振汇合MDCK-MDR1细胞单层的渗透性测量系用作活体外吸收模型:在自顶端至基底(AB)及自基底至顶端(BA)输送方向上测量(pH 7.4,37℃)横跨MDCK-MDR1细胞单层的化合物的表观渗透系数(PE)。AB渗透性(PEAB)表示药物自血液至大脑中的吸收且BA渗透性(PEBA)表示药物经由被动渗透以及主动转运机制两者自大脑流出返回至血液中,该等主动输送机制系由在MDCK-MDR1细胞上表达的流出及摄取转运体、主要由过度表达的人类MDR1介导。在两个转运方向上的相同或相似渗透性指示被动渗透(PEBA/PEAB≤1),向量渗透率指示另外的主动转运机制。PEBA高于PEAB(PEBA/PEAB>5)指示涉及由MDR1介导的主动流出,其可使目标折衷以达成充分大脑暴露。因此,此分析提供宝贵的支持以供选择适用于另外的活体内测试的化合物。未受到血脑屏障处的流出限制的高渗透性为待用于主要在CNS中起作用的药物的化合物的有利特征。
此外,本发明的化合物在人类肝脏微粒体中为代谢稳定的(参见表6,代谢稳定性)。因此,预期本发明的化合物在人体内具有有利活体内清除率且因此具有所要作用持续时间。
人类肝脏微粒体中的稳定性系指在选择及/或设计具有有利的药物动力学特性的药物环境中化合物对生体转化的易感性。用于许多药物的主要代谢部位为肝脏。人类肝脏微粒体含有细胞色素P450(CYP),且因此表示用于研究活体外药物代谢的模型系统。人类肝脏微粒体中的经增强稳定性系与若干优点相关,包括增加的生物可用性及足够半衰期,其可实现患者的较低及较不频繁的给药。因此,人类肝脏微粒体中的经增强稳定性为待用于药物的化合物的有利特征。
因此,本发明的化合物必须更适合人类使用。
因此,目标技术问题为提供强力及选择性NR2B负向立体异位调节剂。
本发明提供新颖的式A的4-吡嗪-2-基甲基-吗啉
其中
R1表示甲基、乙基、丙基、异丙基、环丙基、H3C-CH2-CH2-CH2-、环丁基;
R2表示任选经1、2或3个选自由以下组成的群的取代基取代的苯基:氟、氯、甲基、乙基、环丙基;
或其盐,尤其其药学上可接受的盐。
在另一个实施方式中,在通式A中,R2具有如前述实施方式中任一者所定义的相同含义,及
R1表示甲基、乙基。
在另一个实施方式中,在通式A中,R1具有如前述实施方式中任一者所定义的相同含义,及
R2表示
本发明提供新颖的通式A的4-吡嗪-2-基甲基-吗啉,其出乎意料地为NR2B的强力及选择性负向立体异位调节剂。
本发明的另一方面是指作为具有高膜渗透率且无活体外流出的强力及选择性NR2B负向立体异位调节剂的根据式A的化合物。

活体外效应:
活体外药理学活性的测定
可使用以下活体外NMDA NR1/NR2B细胞分析证明本发明的化合物的活性:
方法:
将具有NMDA NR1/NR2B受体的四环素可诱导的表达的人类HEK293细胞株用作化合物功效及效能的测试系统。细胞株系购自ChanTest,目录号#CT6121。通过在FLIPRtetra系统(分子装置)中测量化合物对由甘氨酸/谷氨酸促效作用诱导的胞内钙浓度的影响来测定化合物活性。
细胞培养:
在低温小瓶中获得呈冷冻细胞形式的细胞且将其储存直至在-150℃下使用为止。
细胞生长于培养基(DMEM/F12,10%FBS,5μg/mL杀稻瘟菌素(Blasticidin),150μg/mL新霉素(Zeozin),500μg/mL遗传霉素(Geneticin))中。重要的系密度不超过80%满度(confluence)。为了传代培养,通过维尔烯(Versene)将细胞与烧瓶分离。为了分析,将细胞分离,用诱导培养基(不含谷酰氨酸的DMEM/F12,10%FBS,2μg/mL四环素,2mM氯胺酮)洗涤两次,且在诱导培养基中进行分析之前,接种至384孔纯涂胺盘(Becton Dickinson,50μl中50000个细胞/孔)48h。
化合物制备
将测试化合物以10mM的浓度溶解于100%DMSO中,且在第一步骤中在DMSO中稀释至5mM的浓度,随后在100%DMSO中连续稀释步骤。稀释因子及稀释步骤的数目可根据需要变化。通常,一式两份地制备8种不同浓度的1:5稀释液,利用分析缓冲水溶液(137mM NaCl,4mM KCl,1.8mM CaCl2,10mM HEPES,10mM葡萄糖,pH 7.4)进行物质的进一步中间稀释(1:37.5),使化合物浓度比最终测试浓度高3倍及DMSO为2.7%,从而使分析中的最终DMSO浓度为0.9%。
FLIPR分析:
在分析日,利用分析缓冲液(如上文所描述)将细胞洗3次,在洗后将10μL缓冲液保留在孔中。将10μL Ca试剂盒加样缓冲液(loading buffer)(AAT Bioquest;由含有以下组分的试剂盒制备:组分A:将溶解于200μL DMSO中的Fluo-8 NW及20μl此溶液与由组分B及C制备的10ml缓冲液混合,成分B:10×F127 Plus在组分C中稀释1:10,组分C:HHBS(具有20mM Hepes的Hanks))添加至细胞中且将盘加盖在室温培育60分钟。将含有60μM甘氨酸(20μM最终)及3μM谷氨酸(1μM最终)的20μl分析缓冲液添加至第1至23行,第24行得到不含甘氨酸/谷氨酸的分析缓冲液以用作阴性未刺激对照。在FLIPRtetra装置上读取荧光(指示由于NR1/NR2B离子通道活化造成的钙流入)60秒,以监测谷氨酸诱导的效应。在2分钟之后,将20μL如上文所述制备的化合物稀释液或对照(第1至22列)于分析缓冲液中小心地添加至孔中。在FLIPR tetra装置上再读取荧光6分钟,以监测在通过激动剂活化之后化合物诱导的效应。计算化合物添加后5分钟及5分10秒时的2次测量的平均值,且将该平均值进一步用于IC50计算。各分析微量滴定化合物稀释盘含有具有DMSO对照替代化合物作为甘氨酸/谷氨酸诱导荧光的对照(高对照)的孔(在第23或24行中)及具有1μM参考NR2b NAM作为低对照(化合物22;参考:Layton,Mark E等人,ACS Chemical Neuroscience 2011,2(7),352-362)的孔。
数据评估及计算:
读取仪的输出档案含有孔编号及所测量的平均荧光单元。对于数据评估及计算而言,低对照的测量结果经设定为0%对照且高对照的测量结果经设定为100%对照。使用标准4参数逻辑回归公式计算IC50值。计算:[y=(a-d)/(1+(x/c)^b)+d],a=低值,d=高值;x=浓度M;c=IC50 M;b=斜率。
一般结构A所涵盖且展现低IC50值的NR2B负向立体异位调节剂为优选的。

实验方案&资料分析
Nav1.6实验方案
状态-依赖性抑制:当钠通道保持在去极化电位或长测试脉冲时,通道打开且失活,且随后保持失活直至膜电位逐步回至超极化电位,此时失活的通道自失活恢复至闭合状态。实施例为四卡因(Tetracaine)抑制,其在去极化电位处比在超极化电位处更强。
指令电压
Nav1.6资料分析
细胞保持在-120mV。为了使钠通道(脉冲1)完全失活,在步进至+0mV持续20ms(脉冲2)之前,将细胞脉冲至+0mV持续2500ms且步进回至-120mV持续10ms(以自失活完全恢复,然而结合有药物的通道将不会自失活恢复)。
