In order to search for new psychotropic agents, several conformationally restricted analogs (see Chart 1D) of haloperidol or benperidol were synthesized. cis-and trans-1-[2- (2-Phenylcyclopropyl) ethyl] piperidine derivatives (Xa, Xb, and XXIV) were prepared in several steps from the corresponding cis-and trans-1-phenyl-1-butene derivatives (III and XX). The effect of the compounds on spontaneous motor activity in mice was determined. trans-Isomer (Xb), which was the most active compound, was about 11 times more active than cis-isomer (XXIV). But the activity of Xb was about one-fifth as potent as benperidol. Structure-activity relationships of these compounds are discussed.
为了寻找新的精神药物,合成了几种构象受限的
氟哌啶醇或苯丙
哌啶的类似物(见图表1D)。通过几步反应,从相应的顺式和反式1-苯基-1-
丁烯衍
生物(III和XX)制备了顺式和反式1-[2-(2-苯基环丙基)乙基]
哌啶衍
生物(Xa、Xb和XXIV)。测定了这些化合物对小鼠自发运动活动的影响。反式异构体(Xb)是最活跃的化合物,其活性约为顺式异构体(XXIV)的11倍。但Xb的活性约为苯丙
哌啶的五分之一。讨论了这些化合物的结构-活性关系。
