Muscarinic agonists were tested in two models indicative of clinical antipsychotic activity: conditioned avoidance responding (CAR) in rats and inhibition of apomorphine-induced climbing in mice. The standard muscarinic agonists oxotremorine and pilocarpine were both active in these tests but showed little separation between efficacy and cholinergic side effects. Structure-activity relationships of
在两种指示临床抗精神病活性的模型中测试了毒蕈碱激动剂:大鼠的条件回避反应(CAR)和小鼠中的阿扑吗啡诱导的爬升抑制。标准毒蕈碱激动剂oxotremorine和毛果芸香碱在这些测试中均很活跃,但在功效和胆碱能副作用之间几乎没有分离。显示了烷硫基1,2,5-噻二唑氮杂环型毒蕈碱部分激动剂的结构-活性关系,揭示了exo-6-(3-丙基/丁基硫代1,2,5-噻二唑-4-基)-1 -氮杂双环[3.2.1]辛烷类似物(4a,b和9a,b)是最有效的抗精神病药,在疗效和胆碱能副作用之间有较大的分隔。对映异构体选择性的缺乏表明药效团元素在化合物的镜平面中。提供了一个解释紧密相关化合物功效差异的模型。数据表明毒蕈碱激动剂起功能性多巴胺拮抗剂的作用,它们可能成为精神病患者的新型治疗方法。
