Definitions

  • the present invention relates to a series of alpha-7 nicotine acetylcholine receptor agonists, in particular to a compound of formula (I), a pharmaceutically acceptable salt thereof, or a tautomer thereof, and its medical use.
  • Nicotine acetylcholine receptors belong to the family of ligand-gated cation channels and are regulated by the endogenous agonist acetylcholine. Each receptor is a 5-mer composed of 5 sub-organisms. The homologous or heterologous subunits combine to form different nicotine acetylcholine receptor subtypes, but each subtype has the same basic structural features, and the five subtypes form a water-filled pore structure around a center [Masatomo Ishikawa and Kenji Hashimoto, current Pharmaceutical Design, 2011, 17, 121-129, Caulfield MP. Pharmacol Ther. 1993, 58, 319-79, Jones S, Sudweeks S, Yakel JL. Trends Neurosci. 1999, 22, 555-61]. They display three main functional states when they are affected by agonists: the "shutdown” state, the "channel open” state, and the "shutdown desensitization” state.
  • the a7 nicotine acetylcholine receptor is a homologous subtype and is a well-received target, mainly distributed in the cerebral cortex and hippocampus, which are related to learning, memory and cognition [Seguela P, Wadiche J, Dineley-Miller K, J Neurosci. 1993, 13, 596-604].
  • a7 nicotine acetylcholine receptors have been found around the synapses, where they are responsible for regulating other inputs to neurons and activating various downstream signaling pathways [Berg DK, Conroy WG.J Neurobiol. 2002, 53, 512–23, Shoop RD , Martone ME, Yamada N, et al. J Neurosci.
  • the a7 nicotine acetylcholine receptor not only participates in the process of learning, memory, but also plays an important role in regulating neurotransmitters.
  • the a7 nicotine acetylcholine receptor is highly permeable to calcium ions, is rapidly activated by agonists, and is rapidly desensitized. These characteristics make the a7 nicotine acetylcholine receptors the most potential targets for the repair and improvement of cognitive impairment, such as Alzheimer's disease, psychosis, Parkinson's disease, senile memory loss, and neuropathy.

技术背景
尼古丁乙酰胆碱受体(nAChRs)属于配体-门控阳离子通道家族,受内源性激动剂乙酰胆碱调控。每个受体都是由5个亚体组成的一个5聚体。同源或异源亚体相互组合构成不同的尼古丁乙酰胆碱受体亚型,但各亚型又具有相同的基本结构特征,5个亚体围绕一个中心形成一个充满水的孔状结构[Masatomo Ishikawa and Kenji Hashimoto,current Pharmaceutical Design,2011,17,121-129,Caulfield MP.Pharmacol Ther.1993,58,319–79,Jones S,Sudweeks S,Yakel JL.Trends Neurosci.1999,22,555–61]。他们在受激动剂作用的时候都会显示三种主要的功能状态,即:“关闭休眠”状态,“通道开放”状态和“关闭脱敏”状态。
a7尼古丁乙酰胆碱受体是一种同源亚型,也是备受关注的一个靶点,主要分布在大脑皮层和海马体中,而这些区域与学习,记忆以及认知相关[Seguela P,Wadiche J,Dineley-Miller K,J Neurosci.1993,13,596–604]。另外,突触周围也发现了a7尼古丁乙酰胆碱受体,在这里他们负责调节其他输入到神经元,并且激活各种下游信号通路[Berg DK,Conroy WG.J Neurobiol.2002,53,512–23,Shoop RD,Martone ME,Yamada N,etal.J Neurosci.1999,19,692–704]。因此,a7尼古丁乙酰胆碱受体不仅参与学习,记忆等过程,还在调节神经递质方面起到重要作用。a7尼古丁乙酰胆碱受体对钙离子有较高渗透性,被激动剂快速激活,然后快速脱敏。这些特点使得a7尼古丁乙酰胆碱受体作为最具潜力的靶点被广泛应用在修复和改善认知损伤的疾病领域,比如阿尔兹海默症,精神病,帕金森病,老年性记忆减退,以及神经性疼痛等。
近些年,一大批结构各异的化合物被开发出来作为选择性a7尼古丁乙酰胆碱受体激动剂,部分激动剂和正向变构调节剂。其中一些已经进入人体临床试验阶段,然而,这些化合物在临床试验中呈现的某些不利副作用和药代动力学问题阻碍了他们的进一步发展,因此,目前还没有药物被批准进入市场。

这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物的中性形式接触的方式获得碱加成盐。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机氨或镁盐或类似的盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物的中性形式接触的方式获得酸加成盐。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐(参见Berge et al.,"Pharmaceutical Salts",Journal of Pharmaceutical Science 66:1-19(1977))。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
优选地,以常规方式使盐与碱或酸接触,再分离母体化合物,由此再生化合物的中性形式。化合物的母体形式与其各种盐的形式的不同之处在于某些物理性质,例如在极性溶剂中的溶解度不同。
本文所用的“药学上可接受的盐”属于本发明化合物的衍生物,其中,通过与酸成盐或与碱成盐的方式修饰所述母体化合物。药学上可接受的盐的实例包括但不限于:碱基比如胺的无机酸或有机酸盐、酸根比如羧酸的碱金属或有机盐等等。药学上可接受的盐包括常规的无毒性的盐或母体化合物的季铵盐,例如无毒的无机酸或有机酸所形成的盐。常规的无毒性的盐包括但不限于那些衍生自无机酸和有机酸的盐,所述的无机酸或有机酸选自2-乙酰氧基苯甲酸、2-羟基乙磺酸、乙酸、抗坏血酸、苯磺酸、苯甲酸、碳酸氢根、碳酸、柠檬酸、依地酸、乙烷二磺酸、乙烷磺酸、富马酸、葡庚糖、葡糖酸、谷氨酸、乙醇酸、氢溴酸、盐酸、氢碘酸盐、羟基、羟萘、羟乙磺酸、乳酸、乳糖、十二烷基磺酸、马来酸、苹果酸、扁桃酸、甲烷磺酸、硝酸、草酸、双羟萘酸、泛酸、苯乙酸、磷酸、多聚半乳糖醛、丙酸、水杨酸、硬脂酸、亚乙酸、琥珀酸、氨基磺酸、对氨基苯磺酸、硫酸、单宁、酒石酸和对甲苯磺酸。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。一般地,优选醚、乙酸乙酯、乙醇、异丙醇或乙腈等非水介质。
本发明的某些化合物可以具有不对称碳原子(光学中心)或双键。外消旋体、非对映异构体、几何异构体和单个的异构体都包括在本发明的范围之内。
本文中消旋体、ambiscalemic and scalemic或者对映体纯的化合物的图示法来自Maehr,J.Chem.Ed.1985,62:114-120。1985年,62:114-120。除非另有说明,用楔形键和虚线键表示一个立体中心的绝对构型。当本文所述化合物含有烯属双键或其它几何不对称中心,除非另有规定,它们包括E、Z几何异构体。同样地,所有的互变异构形式均包括在本发明的范围之内。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-和(+)-对对映体、(R)-和(S)-对映体、非对映异构体、(D)-异构体、(L)-异构体,及其外消旋混合物和其他混合物,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚( 3H),碘-125( 125 I)或C-14( 14C)。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为酮基(即=O)时,意味着两个氢原子被取代。酮取代不会发生在芳香基上。术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
除非另有规定,术语“卤代素”或“卤素”本身或作为另一取代基的一部分表示氟、氯、溴或碘原子。此外,术语“卤代烷基”意在包括单卤代烷基和多卤代烷基。例如,术语“卤代(C 1-C 4)烷基”意在包括但不仅限于三 氟甲基、2,2,2-三氟乙基、4-氯丁基和3-溴丙基等等。
卤代烷基的实例包括但不仅限于:三氟甲基、三氯甲基、五氟乙基,和五氯乙基。“烷氧基”代表通过氧桥连接的具有特定数目碳原子的上述烷基。C 1-6烷氧基包括C 1、C 2、C 3、C 4、C 5和C 6的烷氧基。烷氧基的例子包括但不限于:甲氧基、乙氧基、正丙氧基、异丙氧基、正丁氧基、仲丁氧基、叔丁氧基、正戊氧基和S-戊氧基。“环烷基”包括饱和环基,如环丙基、环丁基或环戊基。3-7环烷基包括C 3、C 4、C 5、C 6和C 7环烷基。“链烯基”包括直链或支链构型的烃链,其中该链上任何的稳定位点上存在一个或多个碳-碳双键,例如乙烯基和丙烯基。
术语“卤”或“卤素”是指氟、氯、溴和碘。
除非另有规定,术语“杂”表示杂原子或杂原子团(即含有杂原子的原子团),包括碳(C)和氢(H)以外的原子以及含有这些杂原子的原子团,例如包括氧(O)、氮(N)、硫(S)、硅(Si)、锗(Ge)、铝(Al)、硼(B)、-O-、-S-、=O、=S、-C(=O)O-、-C(=O)-、-C(=S)-、-S(=O)、-S(=O) 2-,以及任选被被取代的-C(=O)N(H)-、-N(H)-、-C(=NH)-、-S(=O) 2N(H)-或-S(=O)N(H)-。
除非另有规定,术语“杂环烷基”意指稳定的含杂原子或杂原子团的单环、双环或三环,它们包含碳原子和1、2、3或4个独立地选自N、O和S的环杂原子。氮和硫杂原子可任选被氧化(即NO和S(O)p)。氮原子可以是被取代的或未取代的(即N或NR,其中R是H或本文已经定义过的其他取代基)。如果产生的化合物是稳定的,本文所述的杂环烷基可以发生碳位或氮位上的取代。杂环烷基中的氮原子任选地被季铵化。一个优选方案是,当杂环中S及O原子的总数超过1时,这些杂原子彼此不相邻。另一个优选方案是,杂环烷基中S及O原子的总数不超过1。桥环也包含在杂环烷基的定义中。当一个或多个原子(即C、O、N或S)连接两个不相邻的碳原子或氮原子时形成桥环。优选的桥环包括但不限于:一个碳原子、两个碳原子、一个氮原子、两个氮原子和一个碳-氮基。值得注意的是,一个桥总是将单环转换成三环。桥环中,环上的取代基也可以出现在桥上。
术语“烷氧基”、“烷氨基”和“烷硫基”(或硫代烷氧基)属于惯用表达,是指分别通过一个氧原子、氨基或硫原子连接到分子的其余部分的那些烷基基团。
环烷基的实例包括但不限于环戊基、环己基、1-环己烯基、3-环己烯基、环庚基等。除非另有规定,术语“芳基”表示多不饱和的芳族烃取代基,可以是单取代、二取代或多取代的,可以是一价、二价或者多价,它可以是单环或多环(比如1至3个环;其中至少一个环是芳族的),它们稠合在一起或共价连接。术语“杂芳基”是指含有一至四个杂原子的芳基(或环)。在一个示范性实例中,杂原子选自B、N、O和S,其中氮和硫原子任选地被氧化,氮原子任选地被季铵化。杂芳基可通过杂原子连接到分子的其余部分。芳基或杂芳基的非限制性实施例包括苯基、1-萘基、2-萘基、4-联苯基、1-吡咯基、2-吡咯基、3-吡咯基、3-吡唑基、2-咪唑基、4-咪唑基、吡嗪基、2-恶唑基、4-恶唑基、2-苯基-4-恶唑基、5-恶唑基、3-异恶唑基、4-异恶唑基、5-异恶唑基、2-噻唑基、4-噻唑基、5-噻唑基、2-呋喃基、3-呋喃基、2-噻吩基、3-噻吩基、2-吡啶基、3-吡啶基、4-吡啶基、 2-嘧啶基、4-嘧啶基、5-苯并噻唑基、嘌呤基、2-苯并咪唑基、5-吲哚基、1-异喹啉基、5-异喹啉基、2-喹喔啉基、5-喹喔啉基、3-喹啉基和6-喹啉基。上述任意一个芳基和杂芳基环系的取代基选自下文所述的可接受的取代基。

测试品对nAChRα7受体激动作用的测试
测试品作为尼古丁乙酰胆碱α7受体激动剂,在活性检测中缺省阳性对照乙酰胆碱(ACh)。缺省变构调节剂PNU-120596时,尼古丁乙酰胆碱α7受体迅速脱敏,难以观察到任何激动剂的激动效应。因此,在待测激动剂乙酰胆碱或测试品中加入1μM PNU-120596。阳性对照剂和变构调节剂PNU-120596(30μM乙酰胆碱+1μM PNU-120596)引起的信号被设置为激活率100%。阴性对照(1μM PNU-120596)引起的信号被设置为激活率0%。测试化合物对尼古丁乙酰胆碱α7受体激动百分比分类为:+激活率<10%,++激活率10%-40%,+++激活率40%-70%,++++激活率70%-100%,结果如表1所示。
