New coumarins and anti-inflammatory constituents from the fruits of Cnidium monnieri.


ABSTRACT: The fruit of Cnidium monnieri is commercially used as healthcare products for the improvement of impotence and skin diseases. Three new coumarins, 3'-O-methylmurraol (1), rel-(1'S,2'S)-1'-O-methylphlojodicarpin (2), and (1'S,2'S)-1'-O-methylvaginol (3), have been isolated from the fruits of C. monnieri, together with 14 known compounds (4-17). The structures of these new compounds were determined through spectroscopic and MS analyses. Compounds 1, 4-12, and 14-17 exhibited inhibition (IC50 ? 7.31 µg/mL) of superoxide anion generation by human neutrophils in response to formyl-l-methionyl-l-leucyl-l-phenylalanine/cytochalasin B (fMLP/CB). Compounds 7, 9-11, 15, and 17 inhibited fMLP/CB-induced elastase release with IC50 values ?7.83 µg/mL. This investigation reveals that bioactive isolates (especially 6, 7, 14, and 17) could be further developed as potential candidates for the treatment or prevention of various inflammatory diseases.
