ABSTRACT:
Disubstituted guanidines, e.g., bis-1,3-(o-isopropylphenyl)guanidine, bis-1,3-(m-isopropylphenyl)guanidine, bis-1,3-(1-naphthyl)guanidine, bis-1,3-(m-methoxyphenyl)guanidine, N-(1-naphthyl)-N'-(o-iodophenyl)-guanidine, N-(1-naphthyl)-N'-(m-ethylphenyl)guanidine, and N-(1-napthyl)-N'-(o-isoproylphenyl) guanidine, exhibit a high binding affinity to phencyclidine (PCP) receptors. These N,N'-disubstituted guanidine derivatives act as non-competitive inhibitors of glutamate-induced responses generated via 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 therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal chord ischemia, brain or spinal cord trauma, as well as being useful for the treatmnet of epilepsy, Alzheimer's disease, Amyotrophic Laterla Scherosis, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.
