Synthesis and evaluation of mansonone F derivatives as topoisomerase inhibitors
摘要:
A series of mansonone F (MF) derivatives were designed and synthesized. These compounds were found to be strong inhibitors for topoisomerases, with much more significant inhibition for topoisomerase II rather than topoisomerase I. The best inhibitor showed 20 times stronger anti-topoisomerase II activity than a positive control Etoposide. The cytotoxic activity of these MF derivatives was evaluated against human cancer cell lines CNE-2 and Glc-82, which showed that these compounds were potent antitumor agents. The structure activity relationships (SARs) study revealed that o-quinone group and pyran ring are important for their cytotoxic activity. (C) 2011 Elsevier Masson SAS. All rights reserved.

Several derivatives of 1-oxaphenalene (II) and 1-oxaphenalene-7,8-quinone have been synthesized in order to support the constitution I of biflorin by comparison of the absorption spectra.
