A cyclopropachromen derivative represented by formula (I):
wherein n represents an integer of 2 to 5; R1 and R2 independently represent a hydrogen atom or an alkyl group having from 1 to 5 carbon atoms, a phenyl group or an aralkyl group having 7 to 10 carbon atoms, or alternatively R1 and R2 form together with the nitrogen atom, to which they are attached, a morpholino group, a thiomorpholino group, a pyrrolidinyl group, a piperidinyl group, a homopiperidinyl group, a piperazinyl group, a homopiperazinyl group, an N-alkylpiperazinyl group, N-alkylhomopiperazinyl group, an N-hydroxyalkylpiperazinyl group or a pyrrolidonyl group or alternatively R1 and R2 form together with the nitrogen atom to which they are attached, and further a carbon atom to which said nitrogen atom is bound, a pyrrolitidinyl group; A1 and A2 independently represent a hydrogen atom, a hydroxyl group, a halogen atom or an optionally substituted alkoxy group; B1 and B2 independently represent a hydrogen atom, a hydroxyl group, a halogen atom or an optionally substituted alkoxy group; provided that where R1 and R2 both represent a hydrogen atom, A1, A2, B1 and 82 on the two benzene rings all represent a hydrogen atom or, otherwise, the two substituents on at least one benzene ring have the meaning other than a hydrogen atom, and a pharmaceutically acceptable salt thereof are disclosed. The compounds are useful as improving and treating agents for cerebral organic disorders and psychic function disorders.
由式(I)代表的环丙基苯衍生物:
其中 n 代表 2 至 5 的整数;R1 和 R2 独立地代表氢原子或具有 1 至 5 个碳原子的烷基、苯基或具有 7 至 10 个碳原子的芳烷基,或者 R1 和 R2 与它们所连接的氮原子一起形成吗啉基、硫代吗啉基、吡咯烷基、哌啶基、均哌啶基、哌嗪基、均哌嗪基、哌嗪基、N-烷基哌嗪基、N-烷基高哌嗪基、N-羟基烷基哌嗪基或吡咯烷基,或者 R1 和 R2 与它们所连接的氮原子以及与所述氮原子结合的碳原子一起形成吡咯烷基;A1和A2独立地代表一个氢原子、一个羟基、一个卤素原子或一个任选取代的烷氧基;B1和B2独立地代表一个氢原子、一个羟基、一个卤素原子或一个任选取代的烷氧基;条件是当R1和R2均代表一个氢原子时,两个苯环上的A1、A2、B1和82均代表一个氢原子,否则,至少一个苯环上的两个取代基具有氢原子以外的含义,本发明公开了这些化合物及其药学上可接受的盐。这些化合物可作为改善和治疗脑器质性疾病和精神功能障碍的药物。
