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盐。已经证明这些化合物与N
MDA受体有很好的亲和力,因此它们在治疗疾病方面非常有用,其中治疗指标包括急性神经退化的形式,例如中风或脑外伤引起的急性神经退化;慢性神经退化,如阿尔茨海默病、帕
金森病、亨廷顿病或ALS(肌萎缩侧索硬化症);与细菌或病毒感染相关的神经退化,以及精神分裂症、焦虑、抑郁和慢性/急性疼痛等疾病。
