Description
技术领域
本发明涉及医学领域。更具体地,本发明涉及作为σ-1受体激动剂的化合物及其用于治疗中枢神经系统障碍的用途,所述中枢神经系统障碍包括认知或神经退行性障碍,例如阿尔茨海默病、帕金森病、亨廷顿病、肌萎缩侧索硬化症和多发性硬化症。
背景技术
两种σ受体亚型已基于其药理学特征被鉴定。
σ-1受体是一种膜相关蛋白,遍布全身并且在中枢神经系统、神经元、星形胶质细胞、少突胶质细胞和小胶质细胞中广泛表达。σ-1受体是包含223个氨基酸的单一多肽跨膜蛋白。作为单一的25kD多肽和伴侣蛋白,它在线粒体相关内质网(ER)膜和质膜处高度表达。其所鉴定的伙伴蛋白中包括葡萄糖相关蛋白78/结合免疫球蛋白(BiP)和肌醇-1,4,5三磷酸(IP3)受体。σ-1受体是一种配体操控的伴侣蛋白,其与多种类别的药理学化合物(包括例如bezomorphan的右旋异构体,例如(+)-喷他佐辛和(+)-SKF-10,047)结合并被其激活/失活。尽管已确定某些内源性配体与σ-1受体相互作用,例如神经(活性)类固醇、神经肽、胆碱或微量胺,但高亲和力内源性σ-1受体配体的存在仍不清楚。激动剂对σ-1受体的激活具有若干细胞后果,但通过与ER膜上的IP3受体相互作用,主要导致ER与线粒体之间钙交换的放大,并且通过与ER应激感应因子如BiP或IRE-1相互作用,导致ER应激通路的诱导。
据报道,σ-1受体激动剂在若干动物模型中具有抗抑郁作用。例如,选择性σ1受体激动剂(+)-喷他佐辛、(+)-SKF-10,047、伊格美新、OPC14523、DTG或SA4503减少条件性恐惧应激测试中的冻结或强迫游泳测试中的不动时间,或者在悬尾测试中具活性(Matsuno等人,Eur J Pharmacol 312:267-71,1996;Tottori等人,Neuropharmacology 200141:976-88;Urani等人,J Pharmacol Exp Ther 298:1269-79,2001)。
还已报道,它在细胞存活中发挥作用(Wang等人,Exp Cell Res312:1439-46,2006;Hayashi和Su,Cell 131:596-610,2007;Jiang等人,Invest Ophthalmol Vis Sci47:5576-82,2006)。据报道,σ-1受体配体具有神经保护性。据报道,σ-1受体配体奥匹哌醇可防止沙鼠中的局部缺血。此外,其他σ配体,包括BMY-14802、卡拉美芬和氟哌啶醇,在体内模型中表现出与保护作用一致的特性(Pontecorvo等人,Brain Res Bull 26:461-5,1991)。据报道,若干σ配体在体外抑制海马体切片制备物中的缺血诱导的谷氨酸释放(Lobner等人,Neurosci Lett 1 17:169-74,1990)。还已报道,σ-1受体激动剂(+)-喷他佐辛可以保护视网膜细胞免于应激(Dun等人,Invest Ophthalmol Vis Sci 48:4785-94,2007;Smith等人,Invest Ophthalmol Vis Sci 49:4154-61,2008)。
特别注意到具有低σ-2受体亲和力的σ-1受体激动剂在治疗例如来自局灶性缺血的缺血性脑/神经元损伤中的效用。σ-1受体激动剂也被认为可用于改善认知障碍,例如表现出神经递质功能受损(例如乙酰胆碱)以及与年龄相关的认知障碍和与焦虑相关的障碍(包括导致后代学习缺陷的妊娠应激)。
σ-1受体激动剂是有效的抗健忘化合物。这已在啮齿动物中学习和记忆障碍的许多药理学和病理学模型中得到证实。特别是,σ-1受体激动剂在体内针对东莨菪碱诱导的学习缺陷(一种毒蕈碱乙酰胆碱受体(mAChR)阻断模型)进行了常规验证。例如,σ-1受体激动剂LS-1-137(Malik等人,Br J Pharmacol 172:2519-31,2015)、σ-1正调节剂E1R(Zvejniece等人,Br J Pharmacol 171:761-71,2014)或OZP002(Maurice等人,PharmacolRes 144:315-30,2019)或混合型mAChR/σ1激动剂ANAVEX1-41或ANAVEX2-73(布拉美新(blarcamesine)),两种二苯基-3-呋喃甲胺衍生物(Espallergues等人,Br J Pharmacol152:267-79,2017;Villard等人,Neuropsychopharmacology 34:1552-66,2009),最近被表征为针对东莨菪碱诱导的学习障碍的抗健忘药物。σ-1受体激动剂作为认知对症药物的功效不仅在胆碱能健忘模型(例如东莨菪碱、美加明、对氯苯丙胺、前脑损伤)中得到描述,而且在学习缺陷的谷氨酸能模型中也得到描述。非竞争性NMDA受体拮抗剂地卓西平(dizocilpine)(MK-081)诱导的学习障碍已被用于证明σ-1受体对NMDA神经传递施加的正向调节作用,表明在体外或体内使用NMDA诱导的CA3海马体区锥体神经元放电的细胞外记录具有行为后果。σ-1受体激动剂在减轻地卓西平诱导的学习障碍方面的功效也指出这些药物在治疗精神分裂症相关认知缺陷方面的潜在效用,特别是因为低谷氨酸能模型被认为与模拟精神分裂症的阴性症状高度相关(Meltzer等人,Int J Neuropsychopharmacol 16:2181-94,2013)。有趣的是,在东莨菪碱和地卓西平模型中测试的σ-1受体配体在体内显示出相似的活性剂量范围。因此,σ-1受体的激活似乎类似地调节了参与边缘和皮质结构中记忆过程的两种神经传递系统(即胆碱能系统并且特别是谷氨酸能系统)的活性。σ-1受体激动剂在非常低的剂量下增强NMDA诱导的海马体放电。(+)-SKF-10,047(也称为阿拉佐辛(Alazocine))、PRE084和(+)-喷他佐辛增加大鼠海马体中NMDA受体的NR2A和NR2B亚基以及PSD95(也称为SAP-90)的表达。σ-1受体激动剂治疗导致NR2亚基与σ-1受体之间的相互作用增加,并促进NMDA受体向细胞表面的运输。σ-1受体通过调节小电导Ca2+激活的K+电流(SK通道)而与NMDA受体相互作用。在行为水平上,2月龄的年轻雄性σ-1KO小鼠在包括开放场、被动回避和高架十字迷宫在内的程序中表现出焦虑迹象,并且在强迫游泳测试中对应激的反应增强。在雄性动物中,σ1受体消融因此增加了应激和焦虑反应,但记忆反应没有改变。然而,雌性σ-1KO小鼠在自发交替和水迷宫学习范式中表现出记忆改变,并且这种表型随着年龄的增长而增加。值得注意的是,2月龄和14月龄的雌性σ-1KO小鼠显示血浆17β-雌二醇水平降低,并且激素补充治疗逆转了年轻和老年小鼠的记忆缺陷(Chevallier等人,JPsychopharmacol 25:960-75,2011)。这表明σ-1受体消融对甾体紧张(steroidal tonus)有发育影响。
因此,σ-1受体激动剂在与病理性衰老和神经退行性疾病相关的认知改变的啮齿动物模型中是有希望的对症药物。首先,在低mg/kg剂量范围内的伊格美新和PRE-084提高了衰老加速小鼠SAMP/8的学习能力(Maurice等人,Brain Res 733:219-30,1996)。其次,这些化合物还减轻了阿尔茨海默病(AD)药理学模型中由淀粉样蛋白毒性引起的记忆缺陷。(+)-喷他佐辛、PRE-084、库他美新(cutamesine)、二甲啡烷(dimemorphan)、ANAVEX1-41、布拉美新、OZP002和σ-1受体结合神经活性类固醇减轻了接受直接脑室内注射寡聚化Aβ25-35肽的小鼠的学习缺陷,这产生与AD病理学密切相关的神经毒性(Meunier等人,Br JPharmacol.149:998-1012,2006;Villard等人,J Psychopharmacol 25:1101-17,2011;Maurice等人,Pharmacol Res 144:315-30,2019)。在涉及短期以及长期记忆的空间或非空间任务中,所有σ-1受体激动剂或正调节剂都减轻了Aβ25-35诱导的学习障碍。这些作用被BD1047、氟哌啶醇、BMY-14,802和孕酮阻断,这些都是推定的σ-1受体拮抗剂。值得注意的是,虽然它们阻断了σ-1受体激动剂的作用,但单独的拮抗剂并没有改变这些模型中的行为(积极或消极)。因此,σ-1受体激动剂是治疗AD症状的有希望的药剂,其活性剂量与参考药物多奈哌齐(donepezil)、利凡斯的明(rivastigmine)、加兰他敏(galantamine)和美金刚(memantine)相似或更低(Meunier等人,Br J Pharmacol 149:998-1012,2006)。
最后,混合型毒蕈碱和σ-1药物布拉美新已成功完成AD的2期临床试验。所述药物稳定了ADAS-ADL评分,并且在显示最高药物生物利用度的患者中治疗3年后,限制了患者的MMSE评分降低(Hample等人,CTAD Abstracts,2018)。
因此,现在强烈需要开发新的σ-1受体激动剂,以用于治疗与精神病变相关的认知障碍、神经退行性疾病例如阿尔茨海默病、亨廷顿病和帕金森病、肌萎缩侧索硬化症(ALS)或多发性硬化症,以及与MAM(线粒体相关膜)功能障碍相关的遗传疾病。本发明试图满足这个和其他需要。已发现根据本发明的化合物对σ-1受体具有亲和力。

如本文所用,“本发明的化合物”是指上述化合物或其药学上可接受的盐、任何异构体或溶剂化物形式。
术语“异构体”是指具有如本文所鉴定的相同分子式但在性质或它们的原子的结合顺序或它们的原子在空间中的布局方面不同的化合物。其原子在空间中的布局不同的异构体被称为“立体异构体”。彼此不为镜像的立体异构体被称为“非对映异构体”,并且彼此为不可重叠镜像的立体异构体被称为“对映异构体”或“光学异构体”。“立体异构体”是指外消旋物、对映异构体和非对映异构体。
本领域技术人员将认识到立体中心存在于本发明的化合物中。本发明化合物的任何手性中心可以是(R)、(S)或外消旋物。因此,本发明包括式(I)化合物的所有可能的立体异构体和几何异构体,并且不仅包括外消旋化合物,而且还包括旋光异构体。当需要式(I)化合物作为单一对映异构体时,它可以通过拆分最终产物或通过从异构纯的起始材料或任何合适的中间体立体特异性合成而获得。最终产物、中间体或起始材料的拆分可以通过本领域中已知的任何合适方法进行。参见例如E.L.Eliel的碳化合物的立体化学(Stereochemistry of Carbon Compounds(Mcgraw Hill,1962))和S.H.Wilen的拆分试剂列表(Tables of Resolving Agents)。
有机化学领域的专家会理解,许多有机化合物可以与溶剂形成络合物,它们在溶剂中反应或从溶剂中沉淀或结晶。这些络合物被称为“溶剂化物”。例如,与水的络合物被称为“水合物”。式(I)化合物的溶剂化物在本发明的范围内。
有机化学专家也会理解,许多有机化合物可以以超过一种结晶形式存在。例如,结晶形式可能因不同溶剂化物而异。因此,本发明化合物或其药学上可接受的溶剂化物的所有结晶形式都在本发明的范围内。
本发明化合物的术语“药学上可接受的盐”或“药用盐”包括由药学上可接受的无机或有机酸或碱形成的常规盐以及季铵盐。合适的酸盐的更具体实例包括盐酸、氢溴酸、硫酸、磷酸、硝酸、高氯酸、富马酸、乙酸、丙酸、琥珀酸、乙醇酸、甲酸、乳酸、马来酸、酒石酸、柠檬酸、棕榈酸、丙二酸、羟基马来酸、苯乙酸、谷氨酸、苯甲酸、水杨酸、富马酸、甲苯磺酸、甲磺酸、萘-2-磺酸、苯磺酸、羟基萘酸、氢碘酸、苹果酸、硬脂酸、单宁酸等。合适的碱盐的更具体实例包括钠盐、锂盐、钾盐、镁盐、铝盐、钙盐、锌盐、N,N'-二苄基乙二胺盐、氯普鲁卡因盐、胆碱盐、二乙醇胺盐、乙二胺盐、N-甲基葡糖胺盐和普鲁卡因盐。
