  Selective antiproliferative activity of caffeic acid phenethyl ester analogues on highly liver-Metastatic murine colon 26-L5 carcinoma cell line

  摘要：

  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 muM). In addition, CAPE (2) induced DNA fragmentation at concentrations of 1 to 10 mug/mL towards murine colon 26-L5 carcinoma cells. (C) 2002 Elsevier Science Ltd. All rights reserved.

  Intramolecular anodic olefin coupling reactions: a useful method for carbon-carbon bond formation

  摘要：

  The utility of intramolecular anodic olefin coupling reactions for effecting carbon-carbon bond formation has been examined. All of the successful cyclizations studied utilized either an alkyl or silyl enol ether as one of the participating olefins. The enol ethers could be coupled to simple alkyl olefins, styrenes, and allylsilanes in isolated yields ranging from 57 to 84%. The reactions were found to be effective for generating both five- and six-membered rings. The best conditions for cyclization utilized a reticulated vitreous carbon anode, constant-current conditions in an undivided cell, and a lithium perchlorate in either 50% methanol/tetrahydrofuran or 20% methanol/dichloromethane electrolyte solution. The use of an allylsilane as one of the participating olefins allowed for the regiospecific formation of olefinic products. In addition to the olefinic products, these reactions produced a small amount of a cyclized ether product in which the silyl group had not been eliminated. Deuterium-labeling studies showed that at least half of this ether byproduct arose from intramolecular migration of the methoxy group that was initially part of the starting enol ether to the carbon-beta to the silyl group. Intramolecular migration reactions of this type were found to participate in a number of the reported cyclization reactions.
