Abstract

In the light of previous QSAR studies on flavones as inhibitors of xanthine oxidase, we synthesized and tested a new series of 7-hydroxyflavones carrying a wide and balanced variety of substituents (π, σp) at the 4′ position in order to explore the effect of substituents at this position on the xanthine oxidase inhibitory activity. The results of pKa determinations show that the electronic effects of the substituents are not transferred to the hydroxyl at C7, ...
