The invention relates to compounds of the general formula
wherein
R1 signifies hydrogen or hydroxy; R2 signifies hydrogen or methyl; and X signifies —O— or —CH2— and their pharmaceutically acceptable acid addition salts.
It has been shown that these compounds have a good affitity to the NMDA receptor and they are therefore useful in the treatment of diseases, wherein the therapeutic indications include acute forms of neurodegeneration caused, e.g., by stroke or brain trauma; chronic forms of neurodegeneration such as Alzheimer's disease, Parkinson's disease, Huntington's disease or ALS (amyotrophic lateral sclerosis); neurodegeneration associated with bacterial or viral infections, and, diseases such as schizophrenia, anxiety, depression and chronic/acute pain.
本发明涉及一般式化合物,其中R1表示氢或羟基;R2表示氢或甲基;X表示—O—或—CH2—及其药学上可接受的酸加成盐。已经证明这些化合物对NMDA受体具有良好的亲和力,因此它们在治疗疾病方面非常有用,其中治疗适应症包括由中风或脑外伤等引起的神经退行性急性形式;阿尔茨海默病、帕金森病、亨廷顿病或ALS(肌萎缩侧索硬化症)等神经退行性慢性形式;与细菌或病毒感染相关的神经退行性以及精神分裂症、焦虑症、抑郁症和慢性/急性疼痛等疾病。
