摘要：Tumor-reducing effect in vivo and antioxidant effect in vitro of 12 sydnone-substituted chalcones having various groups on the benzene ring were studied. All of them were found to be cytotoxic to tumor cells in vitro , while only methyl substitution increased the in vivo tumor-reducing activity. Some of the substituted chalcones were found to inhibit lipid peroxidation and scavenge superoxides and hydroxyl radicals in vitro . The biological activities of the chalcones were compared with those of curcumin I, an analog of chalcone with known antioxidant activity; and although the sydnone-substituted chalcones had higher cytotoxicity than curcumin I, their tumor-reducing and antioxidant activity were lower. Tumor-reducing activity was found to be independent of their antioxidant activity.
