The synthesis of O-propynyloximes of N-methylpiperidinone, 3-tropinone, and 3-quinuclidinone, containing several pyrazole frameworks is described, together with their muscarinic receptor affinities. Compounds derived from N-methylpiperidinone or 3-tropinone and N-(4-methoxybenzyl)- or N-(2,4,6-trimethylbenzoyl)pyrazole showed moderate activity for muscarinic receptors in the rat central nervous system
描述了含有几个吡唑骨架的N-甲基哌啶酮,3-托皮酮和3-奎宁环酮的O-丙炔肟的合成,以及它们的毒蕈碱受体亲和力。源自N-甲基哌啶酮或3-tropinone和N-(4-甲氧基苄基)-或N-(2,4,6-三甲基苯甲酰基)吡唑的化合物对大鼠中枢神经系统中的毒蕈碱受体具有中等活性。半经验AM1计算表明,肌钙蛋白的O-[((苯甲酰基-吡唑基)丙炔基]-肟)符合先前描述的毒蕈碱药效学模型,揭示了对开发新型毒蕈碱剂有用的结构特征。
