and tested as potential muscarinic antagonists. The compounds display moderate to low affinity for the three receptor subtypes M1-M3, with some of them showing a significant selectivity for the M3 subtype. The configurational and conformational properties were studied using NOE experiments and vicinal coupling constants. The 1H and 13C NMR chemical shifts show stereochemically dependent trends.

合成了一系列带有羟甲基或酯官能团的基于1,3-二氧戊环的配体,并将其作为潜在的毒蕈碱拮抗剂进行了测试。这些化合物对三种受体亚型M1-M3表现出中等至低的亲和力,其中一些对M3亚型表现出显着的选择性。使用NOE实验和邻近耦合常数研究了构型和构象性质。1H和13C NMR化学位移显示立体化学依赖性趋势。构象种群的定量分析表明,环外CH 2 N CH 3)3基团在顺式异构体中普遍以伪轴向取向,在反式异构体中以伪赤道取向为主。
