Like many other flavonoids, 4′,7-dihydroxyflavone has been found to possess activity at opioid receptors in vitro. Specifically, it acts as an antagonist of the μ-opioid receptor and, with lower affinity, of the κ- and δ-opioid receptors.
- Pratol (7-hydroxy-4′-methoxyflavone) is the O-methylated form of the molecule.
