    • Disclosed are a novel optically active compound represented by formula (1), a racemic modification thereof, and a pharmaceutically acceptable acid addition salt of the optically active compound or racemic modification thereof: ##STR1## wherein R is a straight chain or branched C.sub.1 -C.sub.5 aliphatic group which is saturated or unsaturated, or a phenyl group which is unsubstituted or substituted with 1 to 3 substituents which are each independently selected from the group consisting of a halogen atom, a C.sub.1 -C.sub.4 alkyl group, a nitro group, an amino group, a hydroxyl group and a C.sub.1 -C.sub.4 alkoxy group; and mark * indicates an asymmetric carbon atom.The novel optically active aminoalkylcyclopropane derivative of the present invention, a racemic modification thereof, and a pharmaceutically acceptable acid addition salt of the optically active aminoalkylcyclopropane derivative or racemic modification thereof have remarkably high antagonistic activity with respect to NMDA receptor, as compared to known aminomethylcyclopropane derivatives and is useful as a preventive agent for cerebral infarction and a protective agent against ischemic diseases.
