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

Caffeic acid phenethyl ester (CAPE, 2) and its 20 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, 0.02μM). In addition, CAPE (2) induced DNA fragmentation at concentrations of 1 to 10μg/mL towards murine colon 26-L5 carcinoma cells. Copyright

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

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 e

Imidazolidinones as brain activators

This invention relates to imidazolidinone compounds of the formula STR1 wherein Q is methylene group or a single bond: R is a heterocyclic group selected from the group consisting of pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl and 1,3-thiazolyl which may be unsubstituted or with a substituent selected from the group consisting of lower alkyl, lower alkoxy and halogen atom, wherein R is bonded to Q or, when Q is a single bond, to the imidazolidinone ring, through the carbon atom of R; the ring A is an unsubstituted phenyl or a substituted phenyl having 1 or 2 substituent(s) selected from the group consisting of lower alkyl, lower alkoxy, halogen, lower alkylthio, trihalogeno-lower alkyl and nitro; Y is vinylene group or ethynylene; m is a integer from 1 to 6 and n is 0, 1 or 2, or a pharmacetically acceptable salt thereof. These compounds aer useful as cerebral activators, anti-depressants and nootropic drugs.
