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]

  • Pratol (7-hydroxy-4-methoxyflavone) is the O-methylated form of the molecule.
