N2 - In order to develop potential anti-cancer agents that act on topoisomerase II and DNA, we have synthesized 12 new xanthone derivatives. In the cytotoxicity test, compounds 17 and 31 exhibited 2- to 7-fold stronger inhibitory activity than adriamycin against most cancer cell lines tested. Halohydrin group-tethered compounds 19, 21 and 27 showed comparable topoisomerase II inhibitory activity to etoposide at 100 μM concentration. In the DNA cross-linking test, compounds 20, 30 and 31 produced DNA cross-linked adducts and compound 30 was the strongest DNA cross-linker. Based on the combined pharmacological results, we suspected that the strong anti-cancer activity of compounds 16, 17, 20, 30 and 31 originated from the DNA mono-alkylation or cross-linking properties of the compounds. In order to develop potential anti-cancer agents that act on topoisomerase II and DNA, we have synthesized 12 new xanthone derivatives.
