Structure-affinity relationship of flavones on binding to serum albumins: effect of hydroxyl groups on ring A.
Four flavones (flavone, 7-hydroxyflavone, chrysin, and baicalein) sharing the same B- and C-ring structure but a different numbers of hydroxyl groups on the A-ring were studied for their affinitiesExpand
