Description

抗神经学疾病的杂环乙烯基醚
本发明涉及用于治疗或预防疾病的通式I杂环乙烯基醚及其可药用盐,
Figure A9880799100041
其中R代表卤素或低级烷基;n代表0-3;R1代表低级烷基;环烷基;任选被羟基,卤素,低级烷氧基或低级烷基取代的苄基;任选被氨基,低级烷基氨基或二低级烷基氨基取代的苯甲酰基;乙酰基或环烷基-羰基;及代表5员芳香基,它通过N原子连接,除连接的N原子外它还含有1-3个N原子。
很久以前就已经知道某些三唑衍生物落入式I中。例如欧洲专利申请079 856描述了它们被作为农业化学害虫控制的活性物质,尤其是用来控制和预防微生物侵蚀。
现出人意料地发现,通式I化合物是代谢(metabotropic)谷氨酸(盐)受体拮抗剂和/或激动剂。
在中枢神经系统(CNS)中刺激的传递是通过神经递质与神经受体的相互作用完成的,神经递质由神经元发送。
L-谷氨酸,即CNS中最常见的神经递质,在大量生理过程中起着决定性的作用。谷氨酸(盐)依赖性刺激受体被分成两个主组。第一个主组形成配体控制的离子通道。代谢谷氨酸(盐)受体(mGluR)属于第二个主组,而且属于G-蛋白偶合的受体家族。
目前,已经知道mGluR的8个不同成员和它们中一些成员的亚型。根据结构参数,对二次代谢物合成的不同影响以及对小分子量化合物的不同亲和力,这8个受体可以细分成3个次组:mGluR1和mGluR5属于I组,mGluR2和mGluR3属于II组,而mGluR4,mGluR6,mGluR7和mGluR8属于III组。
属于第二个主组的代谢谷氨酸(盐)受体的配体可用来治疗或预防急性和/或慢性神经学疾病,如手术后或(器官)移植后引起的脑功能受限,脑部供血不足,脊髓损伤,头部损伤,妊娠引起的氧不足,心动停止和低血糖。
其它可治疗的相关疾病包括阿尔茨海默病,亨廷顿舞蹈病,肌萎缩性侧索硬化(ALS),AIDS引起的痴呆,眼损伤,视网膜病,认知性疾病,药物引起的特发性帕金森病或帕金森病,以及缺乏谷氨酸(盐)的导致功能性疾病,如肌肉痉挛,惊厥,偏头痛,尿失禁,尼古丁上瘾,精神病,鸦片上瘾,焦虑,呕吐,慢性疼痛,运动障碍,抑郁和疼痛。
本发明的目的是式I化合物及其可药用盐作为治疗活性物质的用途,以及含有这些化合物的药物及其制备,尤其是式I中的新化合物及其可药用盐及作为药物活性物质用于控制或预防上述各种疾病。
式I中的新化合物特指其中R和R1定义如上,代表一个5员芳香环的那些化合物,该环通过N原子连接而且除了这个连接的N原子之外还含有1-3个N原子,或者指R定义如上,代表5员芳香环和R1代表环烷基的那些化合物,该5员环通过N原子连接,而且除了这个连接的N原子之外还含有1-3个N原子。
本发明所用术语“低级烷基”指带有1-7个,优选1-4个碳原子的直链或支链饱和烃基,例如甲基,乙基,正丙基,异丙基等。
术语“环烷基”指环上有3-7个碳原子的饱和环状烃基,例如环丙基,环丁基,环戊基,环己基等。
术语“低级烷氧基”指通过氧原子连接的上面定义的低级烷基。
术语“卤素”指氟、氯、溴和碘。
在本发明范围内,其中R代表氯,n是1或2,R1代表低级烷基,环己基或苄基和代表经过N原子连接的5员芳香环并且除了这个连接的N原子之外还含有2或3个N原子的那些通式I化合物优选用作治疗活性物质。
以下是优选的通式I化合物的实例:
1-[2-(2,4-二氯-苯基)-2-环己氧基-乙烯基]-1H-[1,2,4]三唑,
1-[2-(2,4-二氯-苯基)-2-苄氧基-乙烯基]-1H-四唑,
1-[2-(4-氯-苯基)-2-丁氧基-乙烯基]-2H-四唑,
1-[2-(4-氯-苯基)-2-丁氧基-乙烯基]-1H-[1,2,4]三唑及
1-[2-(2,6-二氯-苯基)-2-丁氧基-乙烯基]-1H-[1,2,4]三唑。
根据本发明,通式I的新化合物可通过烷基化或酰化式II化合物制备,
Figure A9880799100061
其中,R,n和定义如前,如果需要,可将得到的式I化合物转化为可药用盐。
如果需要,可以将式I化合物中的官能团转化为不同的官能团;具体来说,可以将氨基烷基化成低级烷基氨基或二低级烷基氨基,或将羟基烷基化。这些方法是本领域技术人员所熟悉的。
在烷基化或酰化反应中式II的苯乙酮衍生物是与适当烷基化试剂或酰基化试剂反应,优选与苄基溴,苯甲酰氯,乙酰氯,三氟甲磺酸环己基酯,环丙基氯,异丙基溴,正丁基溴,4-甲氧基苄基氯,三氟甲磺酸异丙基酯,4-二甲氨基苯甲酰氯,苄基氯等反应。该反应可根据已知方法进行,优选在氢化钠存在下进行。比例为3∶1的THF(四氢呋喃)和DMPU(1,3-二甲基-3,4,5,6-四氢-2(1H)-嘧啶酮)特别适合用作溶剂。
该制备方法将在实施例1b)中详细描述。
根据本身已知的方法并考虑到要转化成盐的化合物的性质可以很容易地制备可药用盐。下列无机酸或有机酸适用于制备式I碱性化合物的可药用盐:盐酸,氢溴酸,硫酸,硝酸,磷酸或柠檬酸,甲酸,富马酸,马来酸,乙酸,琥珀酸,酒石酸,甲磺酸,对甲苯磺酸等。含有碱金属或碱土金属,如钠,钾,钙,镁等,碱性胺或碱性氨基酸的化合物都适于制备酸性化合物的可药用盐。
