Infobox references

4',7-Dihydroxyflavone is a flavone. It is found in Medicago truncatula in relation with the root nodulation symbiont Sinorhizobium meliloti^[1] or in seeds of Sophora viciifolia.^[2]

Like many other flavonoids, 4',7-dihydroxyflavone has been found to possess activity at the opioid receptors.^[3] Specifically, it acts as an antagonist of the μ-opioid receptor and, with lower affinity, of the κ- and δ-opioid receptors.^[3]
