Carpesabrolide A, a novel meroterpenoid with anti-inflammatory activity from Carpesium abrotanoides.

ABSTRACT: Carpesabrolide A (1), featuring an unprecedented fumaric acid-guaiane sesquiterpenoid hybrid, has been isolated from the folk medicinal plant Carpesium abrotanoides. The structure with absolute configuration has been established by spectroscopic methods and single crystal X-ray diffraction analysis. The plausible biosynthetic pathway for 1 is proposed. Compound 1 shows significant anti-inflammatory activity by inhibiting NO production with an IC₅₀ value of 2.7 μM.
