Abstract
本发明提供式(I)的化合物,其中取代基如本申请中所定义。该化合物是有价值的甘氨酸运载蛋白抑制剂。
Description
本发明涉及新的化合物,其为甘氨酸运载蛋白抑制剂,因而可有效用于治疗CNS障碍。
发明背景
谷氨酸是哺乳动物中枢神经系统(CNS)中主要的兴奋性氨基酸,并通过两种类型的受体起作用,分别为ionotropic和metabotrobic受体。ionotropic谷氨酸盐受体可根据激动剂对这些受体的亲合性分成三个亚型,即N-甲基-D-天冬氨酸(NMDA),(R,S)-2-氨基-3-(3-羟基-5-甲基异噁唑-4-基)丙酸(AMPA)和红藻氨酸(或红藻胺酸盐)受体。
NMDA受体含有调制化合物比如甘氨酸和聚胺的结合位点。甘氨酸与其受体的结合可提高NMDA受体的活化作用。这样的NMDA受体活化作用可能是治疗精神分裂症及其它与NMDA受体机能障碍有关的疾病的潜在目标。通过甘氨酸运载蛋白的抑制剂可以实现活化作用。
分子克隆显示存在两种甘氨酸运载蛋白,GlyT-1和GlyT-2,其中GlyT-1可以更进一步地细分成GlyT-1a,GlyT-1b和GlyT-1c。
NMDA受体被诱导类似精神分裂症的精神病状态的化合物比如苯西克定阻断。同样地,NMDA拮抗剂,比如氯胺酮,可诱导类似于精神分裂症的消极和认知的病征。这表明NMDA受体机能障碍与精神分裂症的病理生理学有关。
NMDA受体与若干疾病,比如疼痛(Yaksh Pain 1989,37,111-123),痉挛,肌阵挛和癫痫(Truong等人,Movement Disorders 1988,3,77-87),学习和记忆(Rison等人,Neurosci.Biobehav.Rev.1995,19,533-552)有关。
甘氨酸运载蛋白拮抗剂或抑制剂被认为在治疗精神分裂症中是非常有益的(Javitt WO 97/20533)。
甘氨酸运载拮抗剂或抑制剂可有效用于治疗精神分裂症及其它精神病的阳性和阴性症状,和用于改善在认知过程减弱的症状中的认知,即阿尔茨海默氏病,多发性脑梗塞痴呆,AIDS痴呆,亨廷顿舞蹈病,帕金森氏症,肌萎缩性侧索硬化或大脑由于内部或外部影响损坏的疾病,比如头部外伤或中风。同样地,惊厥性疾患比如癫痫,痉挛或肌阵挛可能受益于甘氨酸运载蛋白拮抗剂。
已经有人报告了甘氨酸的临床试验,Javitt等人,Am.J.Psychiatry 1994,151,1234-1236和Leiderman等人,Biol.Psychiatry 1996,39,213-215。据报道用高-剂量甘氨酸治疗可改善精神分裂症的症状。现在仍需要更有效治疗NMDA相关疾病的化合物。
本发明提供了为甘氨酸运载蛋白的有效抑制剂的化合物,而且这些化合物可有效地用于治疗与NMDA机能障碍有关的疾病。
