A series of 3,7-disubstituted-2-(3',4'-dihydroxyphenyl)flavones was synthesized as potential cardioprotective agents in doxorubicin antitumor therapy. The influence of substituents on the 3 and 7 positions of the flavone nucleus on radical scavenging and antioxidant properties was explored to improve the antioxidant activity of our lead compound monoHER. In the TEAC assay most compounds had a similar
