Triterpenoic acids (oleanolic, ursolic, betulinic, platanic and glycyrrhetinic acid) were acetylated and coupled with 1,3- or 1,4-diazabicyclo[3.2.2]nonanes to yield amides. Reaction of these amides with methyl iodide at the distal nitrogen of the bicyclic system gave the corresponding quaternary ammonium salts. These compounds were shown to act as excellent inhibitors of the enzyme butyrylcholinesterase
三萜酸(齐墩果酸、熊果酸、桦木酸、铂酸和甘草次酸)被乙酰化并与1,3-或1,4-二氮杂双环[3.2.2]壬烷偶联生成酰胺。这些酰胺与碘甲烷在双环系统的远端氮上反应,得到相应的季铵盐。这些化合物被证明是丁酰胆碱酯酶 (BChE) 的优异抑制剂,而对乙酰胆碱酯酶 (AChE) 的抑制剂仅较弱。酶动力学评估表明这些化合物可作为 BChE 的双曲线抑制剂,而分子模型的结果解释了它们在 AChE 和 BChE 之间的选择性。
