spirocyclopiperazinium derivatives 7a-n and 10a-h were synthesized and evaluated for their in vivo analgesic and sedative activities. Compounds 7f and 10c were discovered to exhibit excellent analgesic activity. Structure-activity relationships revealed that anion of the quaternary salt affected the analgesic and sedative activity significantly; the allyl group is a most effective group among the compounds
基于化合物3的结构,合成了两个螺环哌嗪鎓衍生物系列7a-n和10a-h,并评估了它们的体内止痛和镇静活性。发现化合物7f和10c显示出优异的镇痛活性。构效关系表明季盐阴离子显着影响镇痛和镇静作用。烯丙基是化合物7a-n中最有效的基团。芳环上电子释放的取代基有利于增加镇痛活性。
