and tested for muscarinic receptor binding affinity using [3H]pirenzepine and [3H]oxotremorine M as ligands. They were also evaluated for agonistic activities in the guinea pig ileum assay. 2-Methoxy- 2,8-diazaspiro[4.5]decane-1,3-dione (1i) was found to be a relatively M1 selective agonist. It reversed CO2-induced impairment of passive avoidance response with long duration of action, but also displayed
合成了一系列的2-烷氧基-2,8-二氮杂螺[4.5]癸烷-1,3-二酮和相关化合物,并以[3H]哌仑西平和[3H]氧代苯甲酸M作为配体测试了毒蕈碱受体的结合亲和力。还通过豚鼠回肠试验评估了它们的激动活性。发现2-甲氧基-2,8-二氮杂螺[4.5]癸烷-1,3-二酮(1i)是相对M1选择性的激动剂。它以较长的作用时间逆转了CO2引起的被动回避反应的损害,但在低剂量时也表现出外周效应。为了最小化这些副作用,我们提出了将1i与毒蕈碱拮抗剂结合的想法。因此,检查了1i的氨基甲酸酯连接的共轭物(1u)与甲基阿托品。
