The reduction of aromatic nitrocompounds to the corresponding amines with silanes catalyzed by high valent oxo-rhenium complexes is reported. The catalytic systems PhMe2SiH/ReIO2(PPh3)2 (5 mol %) and PhMe2SiH/ReOCl3(PPh3)2 (5 mol %) reduced efficiently a series of aromatic nitrocompounds in the presence of a wide range of functional groups such as ester, halo, amide, sulfone, lactone, and benzyl

hylguanidine (40) showed high affinity for the NMDA receptor ion channel site (IC50 = 36 nM vs [3H]-3) and low affinity for sigma receptors (IC50 = 2540 nM vs [3H]-5). Selectivity for the NMDA receptor ion channel sites over sigma receptors appears to be dependent upon the structure of the additional substituents on the guanidine nitrogen atoms bearing the aryl groups.

Tri- and tetra-substituted guanidines which exhibit a high binding affinity to phencyclidine (PCP) receptors and, more preferably, low affinity to the brain sigma receptors. These guanidine derivatives act as non-competitive inhibitors of 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 neuroprotective activity and are useful in the therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal cord ischemia, and brain or spinal chord trauma as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.
