Certain 1-cyclic amino-alkylcyclohexanes selected from the group consisting of those of formula (I) wherein R* is -(CH2)n-(CR6R7)m-NR8R9; wherein n+m=0,1, or 2; wherein R1 through R2 are independently selected from the group consisting of hydrogen and lower-alkyl (1-6c), at least R1, R4, and R5 being lower-alkyl, and wherein R8 and R9 together represent lower-alkylene -(CH2)x wherein x is 2 to 5, inclusive, and enantiomers, optical isomers, hydrates, and pharmaceutically acceptable salts thereof, are systemically active uncompetitive NMDA receptor antagonists and are therefore useful in the alleviation of conditions resulting from disturbances of glutamatergic transmission. More importantly, these compounds exhibit outstanding anticonvulsant and anti-seizure activity which is not shared by closely-related noncyclic amino compounds. Pharmaceutical compositions thereof and a method-of-treating conditions which are alleviated by the employment of the same, especially the alleviation of convulsions and seizures, and method for the preparation of the active 1-cyclic amino-alkylcyclohexane compounds involved and the manufacture of medicaments therefrom. |
