Recent studies have described novel azabicycle-based muscarinic agonists which readily penetrate into the central nervous system and are capable of displaying high efficacy at cortical sites. The current paper describes the synthesis and biochemical assessment of semirigid muscarinic ligands which were used to map the requirements of the cortical muscarinic receptor and to study the degree of conformational
最近的研究已经描述了新型的基于氮杂双环的毒蕈碱激动剂,其容易渗透到中枢神经系统中并且能够在皮质部位显示出高功效。目前的论文描述了半刚性毒蕈碱配体的合成和生化评估,这些配体用于测绘皮质毒蕈碱受体的需求并研究引起受体活化所需的构象柔性程度。类似物6和9在皮质部位提供高效毒蕈碱激动剂。然而,四氢吡啶环上的C-烷基化产生了更刚性的类似物,并显示出较低的预测功效。分子力学计算表明偏爱E旋转异构体形式。在乙烯基恶二唑12的X射线晶体结构中也观察到该构象。
