1-Hydroxy-2,3,4,7-tetramethoxyxanthone

This small molecule exhibits dual bioactivity, functioning as a coronary vasodilator (EC50 = 6.6 μM against 5-HT-induced contraction) and an inhibitor of osteoclast differentiation in co-culture systems. Its actions support research in cardiovascular pharmacology and bone metabolism, including studies on osteoporosis and vascular tone.
