本文以咖啡酸苯乙酯为先导物设计合成了一系列(1E)-2-(3',4'-二羟基苯基)乙烯磺酸苯酯类化合物作为抗肌萎缩侧索硬化症的药物,并对其神经保护作用进行了活性评估,结果表明将咖啡酸苯乙酯的羧酸酯结构替换成磺酸酯结构后,在LPS诱导BV2细胞产生炎症测定药物神经保护活性的模型中,化合物的活性没有明显提高在过氧化氢H2O2诱导PC12细胞氧化损伤测定药物神经保护活性的模型中,所合成的化合物神经保护作用与咖啡酸苯乙酯处于同一水平。
A series of (1E)-phenyl-2-(3',4'-dihydroxyphenyl)ethenesulfonate derivatives were designed and synthesized as anti-amyotrophic lateral sclerosis (ALS) agents, based on the lead compound caffeic acid phenethyl ester (CAPE). And their neuroprotective activities were evaluated. The results indicated that replacement of the carboxylic ester by sulfonic ester did not produce better neuroprotective activity in the model of LPS induced inflammation in BV2 cells. However, the results in the model of H2O2 induced damage in PC12 cells showed that the neuroprotective activities of all the target compounds and CAPE were about the same.
