Abstract

Cholangiocarcinoma (CCA) is an aggressive malignancy with a very high morbidity and mortality for which an effective treatment is lacking. In this study, seventeen zerumbone derivatives were synthesized and evaluated for in vitro cytotoxicity against cholangiocarcinoma cell lines. 5 showed the most potent antiproliferative activity against KKU-100 cell line with an IC(50) value of 16.44 microM. To investigate the potential molecular target of the most active compound, the docking was performed using different enzymes and receptor proteins including CDK-2, CDK-5, EGFR, and GSK-3. The docking results revealed that 5 exhibited better binding interaction to EGFR than CDK-2, CDK-5 and GSK-3. All results indicate that 5 should be a promising candidate for treatment of cancer.2010 Elsevier Masson SAS. All rights reserved.
