Twenty-one caffeic acid phenethyl ester (CAPE) derivatives were synthesized, and characterized by IR, HR-MS, 1H and 13C NMR analyses. All compounds were evaluated for their cytoprotective effects against H2O2-induced cytotoxicity and neuritogenic activities in the neurite outgrowth in PC12cells. Compounds 1 and 20 exhibited stronger cytoprotective activities than their parent compound CAPE at 4 nM. Compounds
合成了二十一种咖啡酸苯乙酯(CAPE)衍生物,并通过IR,HR-MS,1 H和13 C NMR分析对其进行了表征。评价了所有化合物对PC 12细胞中神经突生长中H 2 O 2诱导的细胞毒性和神经生成活性的细胞保护作用。化合物1和20在4 nM时比其母体化合物CAPE表现出更强的细胞保护活性。化合物1,4,12和13显示出潜在neuritogenic活动在为0.5nM,而化合物19和20在10 nM时引起神经突生长。这项研究的结果表明,CAPE及其衍生物可能是预防神经退行性疾病的潜在功能性食品成分。
