title: Selective antiproliferative activity of caffeic acid phenethyl ester analogues on highly liver-metastatic murine colon 26-L5 carcinoma cell line.
abstract: Caffeic acid phenethyl ester (CAPE, 2) and its twenty analogues (1, 3-21) were prepared. These esters were tested by MTT assay on growth of murine colon 26-L5 carcinoma, murine B16-BL6 malonoma, murine Lewis lung carcinoma, human HT-1080 fibrosarcoma, human lung A549 adenocarcinoma, and human cervix HeLa adenocarcinoma cell lines. It was found that CAPE analogues possessed selective antiproliferative activity toward highly liver-metastatic murine colon 26-L5 carcinoma cell line. Among them, 4-phenylbutyl caffeate (4), (Z)-8-phenyl-7-octenyl (10a) and (E)-8-phenyl-7-octenyl (10b) caffeate showed the most potent antiproliferative activity (EC50 value, 0.02 microM). In addition, CAPE (2) induced DNA fragmentation at concentrations of 1 to 10 microg/mL towards murine colon 26-L5 carcinoma cells.
