Guanidine-containing analogs of amantadine and memantine, including 1-adamantylguanidine hydrochloride (IEM-2151) and 3,5-dimethyl-1-adamantylguanidine hydrochloride (IEM-2163), were synthesized and studied. IEM-2151 and IEM-2163 had greater antihypoxic, anticonvulsant, and neuroprotective activity than memantine; exhibited equally potent antiparkinsonian, antidepressant, and analgesic activity with memantine; and had higher therapeutic indices than memantine.
