Abstract: The new multifunctional antitumor conjugates containing ascorbic acid and 5-fluorouracil (5-FU) were synthesized from bicyclo[2.2.2]oct-7-ene-2,3,5,6-tetracarboxylic dianhydride, ascorbic acid and/or a chain spacer, followed by condensation with 5-FU. The synthesized conjugates were identified by 1 H and 13 C NMR spectroscopies and elemental analysis. The in vitro cytotoxicities of these conjugates were determined and their antitumor activity was evaluated. The IC 50 values (drug concentration for 50% inhibition of tumor growth) indicated that the synthesized conjugates were better inhibitors against cancer cells and were lower in cytotoxicity than the free 5-FU. The in vivo antitumor activity of the conjugates was examined against mice bearing the sarcoma 180 tumor cells. The life spans (T/C) of mice treated with the conjugates were higher than for the free 5-FU. In addition, the synthesized conjugates showed excellent antiangiogenic activity, based on the embryo chorioallantoic membrane assay.
