The present invention discloses compounds of formula (I), their optical isomers or pharmaceutically acceptable salts thereof, their preparation and uses thereof, wherein the definitions of R1, R2, R3 and R4 are shown in the description. These compounds are optical isomers or racemic mixtures. After these compounds are uptaken, they are metabolically transformated in vivo into 1-[2-dimethylamino-1-(4-hydroxyphenyl)-ethyl]-cyclohexanol that has neuropharmacological activity, by interrupting reuptake of 5-hydroxytryptamine (5-HT) and/or norepinephrine (NA), which is used for treating diseases associated with central nerve system, such as depression, etc.
本发明公开了式(I)的化合物,它们的光学异构体或其药学上可接受的盐,它们的制备和用途,其中R1、R2、R3和R4的定义如描述中所示。这些化合物是光学异构体或混合物。这些化合物被摄取后,在体内代谢转化为具有神经药理活性的1-[2-二甲基
氨基-1-(
4-羟基苯基)-乙基]-
环己醇,通过中断5-羟
色胺(5-HT)和/或
去甲肾上腺素(NA)的再摄取,用于治疗与中枢神经系统相关的疾病,如抑郁症等。
