Disubstituted guanidines, e.g., N,N'-di-m-tolyl guanidine, N,N'-di-o-ethylphenyl guanidine, N,N'-di-m-ethylphenyl guanidine, and N,N'-di-o-iodophenyl-guanidine, exhibit a high binding affinity to phenylcyclidine (PCP) receptors. These guanidine derivatives act as non-competitive blockers to glutamate induced responses of the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert a neuroprotective property and are useful in the therapeautic treatment of neuronal loss in ischemia, hypoxia, hypoglycemia, and brain and spinal cord trauma as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Down's Syndrome and other neurodegenerative disorders.
二取代胍胺,例如N,N'-二-间甲苯基胍胺,N,N'-二-邻乙基苯基胍胺,N,N'-二-间乙基苯基胍胺和N,N'-二-邻碘苯基胍胺,对苯环己胺(PCP)受体表现出高结合亲和力。这些胍胺衍生物作为非竞争性阻滞剂,通过作为NMDA受体的离子通道的阻滞剂,对谷氨酸诱导的NMDA受体的反应起作用。这些化合物因此具有神经保护性质,并且在治疗缺血、缺氧、低血糖、脑和脊髓创伤中的神经元丧失方面具有用处,同时也适用于癫痫、阿尔茨海默病、肌萎缩侧索硬化症、亨廷顿病、唐氏综合症和其他神经退行性疾病的治疗。
