As a lead development based on the previous quantitative structure-activity relationship (QSAR) results on cerebral vasodilating activities of 1-benzyl-4-diphenylmethylpiperazines, 1- cinnamyl-4-diphenylmethylpiperazines having electron-donating groups on the cinnamyl moiety were designed. Two methods of synthesis were developed. As expected from the QSAR results, these compounds exhibited stronger potency and longer-lasting effect than cinnarizine and flunarizine.
作为基于先前1-苄基-4-二苯基甲基
哌嗪脑血管舒张活性的定量构效关系(Q
SAR)结果的先导开发,设计了在肉桂基部分上具有给电子基团的1-肉桂基-4-二苯基甲基
哌嗪。开发了两种合成方法。正如 Q
SAR 结果所预期的那样,这些化合物比
桂利嗪和
氟桂利嗪表现出更强的效力和更持久的效果。
