Abstract

Recent study indicated that terpyridine and its derivatives displayed highly active antitumor properties. In this presentation. derivatives of terpyridines having three pyridine moieties at 2',4',6'-position of central pyridine skeleton were prepared, and evaluated their cytotoxicity against several human cancer cell lines and topoisomerase I inhibitory activities. Most of the prepared compounds showed strong cytotoxicity compared to doxorubicln. In addition. several compounds displayed better cytotoxicity than that of doxorubicin. In addition, several compounds displayed better cytotoxicity than that of doxorubicin. Structure-activity relationship study was perfomed to be indicated that [2.2':6',2']terpyidine skeleton is important to show strong xytotoxicity. Significant topoxicity. Significant topoisomerase I inhibitory activity was not observed for prepared compounds.
