Styryl pyranones with apoptosis activities from the sporocarps of Phellinus igniarius

Abstract Three previously unreported compounds, phelliigniarin A (1), phelliigniarin B (2), phelliigniarin C (3), and seven known compounds were isolated and identified from the sporocarps of Phellinus igniarius. These structures were elucidated on the basis of spectroscopic analysis. Compound 4 and 10 triggered apoptosis of Hela-/- cell at the dose of 20 μM.
