A series of CAPE derivatives with mono-substituted phenylethanols moiety were synthesized and evaluated by MTT assay on growth of 4 human cancer cell lines (Hela, DU-145, MCF-7 and ECA-109). The substituent effects on the antiproliferative activity were systematically investigated for the first time. It was found that electron-donating and hydrophobic substituents at 2'-position of phenylethanol moiety could significantly enhance CAPE's antiproliferative activity. 2'-Propoxyl derivative, as a novel caffeic acid ester, exhibited exquisite potency (IC=0.4±0.02 & 0.6±0.03μM against Hela and DU-145 respectively).
合成了一系列带有单取代苯乙醇部分的咖啡酸苯乙酯（CAPE）衍生物，并通过MTT法对4种人类癌细胞系（Hela、DU-145、MCF-7和ECA-109）的生长进行了评估。首次系统研究了取代基对其抗增殖活性的影响。结果发现，苯乙醇部分2'-位的供电子和疏水取代基可显著增强CAPE的抗增殖活性。2'-丙氧基衍生物作为一种新型咖啡酸酯，表现出优异的活性（对Hela和DU-145的IC50分别为0.4±0.02和0.6±0.03μM）。
