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:
wherein R is a straight chain or branched C1-C5 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 C1-C4 alkyl group, a nitro group, an amino group, a hydroxyl group and a C1-C4 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.
本发明公开了一种由式(1)代表的新型光学活性化合物、其外消旋修饰物以及该光学活性化合物或其外消旋修饰物的药学上可接受的酸加成盐:
其中 R 是饱和或不饱和的直链或支链 C1-C5 脂肪族基团,或未被取代或被 1 至 3 个取代基取代的苯基,这些取代基各自独立地选自卤素原子、C1-C4 烷基、硝基、氨基、羟基和 C1-C4 烷氧基组成的组;标记 * 表示不对称碳原子。
与已知的氨基甲基环丙烷衍生物相比,本发明的新型光学活性氨基烷基环丙烷衍生物、其外消旋修饰物以及光学活性氨基烷基环丙烷衍生物或其外消旋修饰物的药学上可接受的酸加成盐对 NMDA 受体具有显著的高拮抗活性,可用作脑梗塞的预防剂和缺血性疾病的保护剂。
