Abstract

The synthesis and biological evaluation of ethyl 5-amino-4-(3-pyridyl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrano[2,3-b]quinoline-3-carboxylates (9-11) is described. We have found that these compounds inhibit AChE with a mild potency, mitigates the Ca(2+) triggered by high K(+), and cause neuroprotection against Ca(2+) overloading and free radical-induced neuronal death.

摘要

描述了5-氨基-4-(3-吡啶基)-2-甲基-6,7,8,9-四氢-4H-吡喃并[2,3-b]喹啉-3-羧酸乙酯(9-11)的合成及生物学评价。我们发现这些化合物以中等效力抑制乙酰胆碱酯酶,减轻高钾引发的[Ca(2+)]c,并对Ca(2+)过载和自由基诱导的神经元死亡具有神经保护作用。
