Neuroactivity of a number of flavonoids is mediated by modulation of type A gamma-aminobutyric acid (GABA(A)) receptor function via benzodiazepine sites, mostly as partial agonists. In the present study, 6,2'-dihydroxyflavone (DHF) was characterized for potential inverse agonistic activity, and its
