Cyproheptadine derivatives substituted with a trifluoromethylthio or trifluoromethylsulfonyl group in one of the benzo rings and having a hydroxyalkyl or cycloalkylalkyl group on the piperidine nitrogen are potent antipsychotic agents, with a low propensity to induce extrapyramidal side effects that are experienced with most major tranquilizers. The tranquilizing activity is predominantly in the levorotatory enantiomers, whereas the dextrorotatory enantiomers have anticholinergic activity. Each enantiomer is useful as a source of the other by racemization. The novel compounds are prepared by treatment of the corresponding iodo or bromo compound with bis(trifluoromethylthio)mercury and copper powder.
一种Cyproheptadine衍生物,在其苯环中的一个上取代有三氟甲基硫醇或三氟甲基磺酰基,并在哌啶氮上具有羟基烷基或环烷基烷基,是有效的抗精神病药物,具有引起大多数主要镇静剂经外锥体副作用的低倾向。镇静活性主要在左旋异构体中,而右旋异构体具有抗胆碱能活性。通过消旋反应,每个对映体都可用作另一个对映体的来源。这些新化合物是通过将相应的碘化物或溴化物化合物与双(三氟甲基硫醇)汞和铜粉处理制备的。
