A class of quinolinic sulfide derivatives of formula I are potent and specific antagonists at the strychnine insensitive glycine bitding site on the NMDA receptor complex with an pharmacological advantageous profile. They may be useful in treatment or prevention of neuro-degenerative disorders. Particularly, the compounds included in the present invention are especially useful for minimizing damage of the central nervous system arising as a consequence of ischemic or hypoxic condition such as stroke, hypoglycemia, cerebral ischemia, cardiac arrest, and physical trauma. They are also useful in prevention of chronic neurodegenerative disorders including epilepsy, Alzheimer's disease, Huntington's disease and Parkinsonism. By virtue of their NMDA receptor antagonist properties, the present compounds may also use as anticonvulsant, analgesic, antidepressant, anxiolytic, and antischizophrenic agent. Formula I ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R are defined in specification.
一类化学式为I的喹啉硫醚衍生物在NMDA受体复合物的士的可卡因不敏感的甘氨酸结合位点上具有强效和特异性拮抗作用,具有药理学上的优势特性。它们可能有助于治疗或预防神经退行性疾病。特别地,本发明中包括的化合物特别适用于减轻中枢神经系统因缺血或缺氧状况(如中风、低血糖、脑缺血、心跳骤停和身体创伤)而引起的损伤。它们还可用于预防慢性神经退行性疾病,包括癫痫、阿尔茨海默病、亨廷顿病和帕金森症。由于它们的NMDA受体拮抗剂特性,本化合物还可用作抗惊厥、镇痛、抗抑郁、抗焦虑和抗精神分裂药物。化学式I如下:##STR1##其中R.sub.1、R.sub.2、R.sub.3、R.sub.4和R在规范中定义。
