oxindole skeleton by anion-based methods provided additional substituted derivatives for structure-activity relationship studies. Their effects on neuronal cell death induced by oxidative stress were evaluated by lactate dehydrogenase assay. Compounds with the alkyl chain length of 2–4 significantly suppressed the neuronal cell death. No significant change occurred in the activity by substitution with
通过以下两种途径之一合成了新型3- [4-(二甲基氨基)苯基]烷基-2-氧吲哚类似物:(1)羟吲哚与(4-二甲基氨基)肉桂醛加氢的Knoevenagel缩合序列,或(2 )用[(4-二甲基氨基)苯基]烷基卤化物对羟吲哚二价阴离子进行烷基化。随后通过基于阴离子的方法在羟吲哚骨架的C-3和/或N-1处进行烷基化,为结构-活性关系研究提供了额外的取代衍生物。通过乳酸脱氢酶测定评估它们对氧化应激诱导的神经元细胞死亡的影响。烷基链长为2-4的化合物可显着抑制神经元细胞死亡。通过用极性较小的基团取代,活性没有发生显着变化。
