The present invention discloses compounds of the formula
or a pharmaceutically-acceptable addition salt thereof
wherein
R' and R'' independently of each other are hydrogen or alkyl, or R' and R'' together form a 3 to 6 membered alkylene chain;
one of R¹ and R² is aryl which may be substituted one or more times with halogen, CF₃, CN, OH, alkyl, cycloalkylalkyl, alkenyl, alkynyl, alkoxy, amino, nitro, sulphamoyl, tetrazolyl, CO₂H, CO₂-alkyl and the other of R¹ and R² is hydrogen, halogen, alkoxy, amino or alkyl; and
R⁴, R⁵, R⁶ and R⁷ independently of each other are hydrogen, halogen, amino, nitro, CN, OH, CF₃, alkyl or alkoxy; and n is 0 or 1; provided that neither of R¹ and R² is phenyl or substituted phenyl when n is 0.
The compounds are useful as pharmaceuticals, for example, in the treatment of ischemia, anoxia, migraine and psychosis.
本发明公开了如下式的化合物
或其药学上可接受的加成盐
其中
R'和 R''各自独立地为氢或烷基,或 R'和 R''共同形成 3 至 6 个成员的亚烷基链;
R¹ 和 R² 中的一个为芳基,可被卤素、CF₃、CN、OH、烷基、环烷基、烯基、炔基、烷氧基、氨基、硝基、氨基磺酰基、四唑基、CO₂H、CO₂-烷基取代一次或多次,R¹ 和 R² 中的另一个为氢、卤素、烷氧基、氨基或烷基;以及
R⁴、R⁵、R⁶ 和 R⁷ 相互独立地为氢、卤素、氨基、硝基、CN、OH、CF₃、烷基或烷氧基;且 n 为 0 或 1;但当 n 为 0 时,R¹ 和 R² 均不是苯基或取代苯基。
这些化合物可用作药物,例如用于治疗缺血、缺氧、偏头痛和精神病。
