Abstract

A new dihydropyranocoumarin, (+)-cis-(3'S,4'S)-diisobutyrylkhellactone (1), together with five known compounds, 3'-senecioyl-4'-acetylkhellactone (2), 3'-isovaleryl-4'-acetylkhellactone (3), 3',4'-disenecioylkhellactone (4), 3'-isovaleryl-4'-senecioylkhellactone (5), and 3',4'-diisovalerylkhellactone (6), was isolated from Glehnia littoralis. Their chemical structures were elucidated based on the spectroscopic data interpretation, particularly 1D and 2D NMR data including HMQC and HMBC. All the isolated compounds showed the potential to inhibit LPS-induced nitric oxide production in RAW 264.7 cells with IC50 values ranging from 7.4 to 44.3μM.
