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.
Cyanide-Free Synthesis of Air Stable N-Substituted Li and K Cyanamide Salts from Tetrazoles. Applications toward the Synthesis of Primary and Secondary Cyanamides as Precursors to Amidines

A practical two-step synthesis of N,N′-disubstituted cyanamides consists in the low-temperature metalation of N-substituted 5H-tetrazoles that undergo spontaneous cycloreversion at 0 °C releasing dinitrogen, and forming N-metalated cyanamides that can be reacted in situ with a variety of electrophiles. Remarkably, the N-substituted Li and K cyanamides are air stable white solids at room temperature. Addition of lithium organometallics to the N,N′-disubstituted cyanamides provides a new method for accessing N,N′-disubstituted amidines.
Selective Gold-Catalysed Synthesis of Cyanamides and 1-Substituted 1H-Tetrazol-5-Amines from Isocyanides

The newly discovered gold-catalysed reaction of isocyanides with hydrazoic acid generated in situ from trimethylsilyl azide and methanol (or, alternatively, from NaN3/AcOH) produces either cyanamides or 1-substituted 1H-tetrazol-5-amines, depending on the amount of available HN3. The reaction proceeds selectively and in generally high yields of either product, thus providing a particularly convenient access to a wide range of substituted 1H-tetrazol-5-amines that are rather difficult to access otherwise.
SUBSTITUTED GUANIDINES HAVING HIGH BINDING TO THE SIGMA RECEPTOR AND THE USE THEREOF
-
, (2008/06/13)
The invention relates to a method for the treatment or prophylaxis of psychosis, depression, hypertension, or anxiety in an animal by administering an effective amount of an N,N'-disubstituted guanidine or 2-iminoimadazolidine having an affinity for the s
