Abstract

Furanoligularenone (1), a known eremophilane, was identified from Ligularia fischeri (Compositae) together with 3-oxo-8α-hydroxy-10αH-eremophila-1,7(11)-dien-12,8β-olide (2) and 3-oxo-8α-methoxy-10αH-eremophila-1,7(11)-dien-12,8β-olide (3), by its potent inhibition of LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production in RAW 264.7 cells. Compound 1 also suppressed the expression of iNOS and COX-2 mRNA and protein in a dose-dependent manner. Taken together, compound 1 inhibits the production of NO and PGE2 at the transcription of iNOS and COX-2 genes, and would be responsible for the anti-inflammatory activities of the Ligularia fischeri.
