  名称：

  Muscarinic cholinergic agonists and antagonists of the 3-(3-alkyl-1,2,4-oxadiazol-5-yl)-1,2,5,6-tetrahydropyridine type. Synthesis and structure-activity relationships

  摘要：

  A series of 3-(3-alkyl-1,2,4-oxadiazol-5-yl)-1,2,5,6-tetrahydro-1-methylpyridines (2a-q) were synthesized and tested for central muscarinic cholinergic receptor binding affinity by using [H-3]oxotremorine-M and [H-3]QNB as ligands and in a functional assay using guinea pig ileum. The analogues with unbranched C1-8-alkyl substituents (2a-g) were agonist, whereas the compounds with branched or cyclic substituents (2h-m) were antagonists. The alkyl ether analogues (2o-q) were also agonists but had lower receptor binding affinity than the corresponding alkyl analogues. The 3-(5-alkyl-1,2,4-oxadiazol-3-yl)-1,2,5,6-tetrahydro-1-methylpyridine analogues had only very low affinity for the central muscarinic receptors and were weak antagonists in the ileum assay. A few 3-(3-butyl-1,2,4-oxadiazol-5-yl)-1,2,5,6-tetrahydro-1-methylpyridines substituted with methyl or hydrogen in the 1-, 5-, or 6-position were synthesized and tested. N-Desmethyl analogue 7 was a potent muscarinic agonist, whereas N-desmethyl-5-methyl analogue 11 and N-methyl-6-methyl analogue 13 both were antagonists with lower muscarinic receptor affinity. The 3-(3-butyl-1,2,4-oxadiazol-5-yl)quinuclidine (17) and tropane (15) analogues were both very potent antagonists with high affinity for central muscarinic receptors. The ratio [IC50(QNB)/IC50(Oxo-M)] x 0.162 proved to be a good indicator of the efficacy of the compounds in the guinea pig ileum assay.

  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。

The exo-1-azanorbornane 16a represents the optimum arrangement, and this compound is one of the most efficacious and potent muscarinic agonists known. In a series of isoquinuclidine based muscarinic agonists efficacy and affinity are influenced by the geometry between the cationic head.group and hydrogen bond acceptor
