A New Indole Alkaloid and Anti-Inflammatory Constituents from Strychnos cathayensis. [JOURNAL ARTICLE]
Chem Biodivers 2008 Jul 22; 5(7):1345-1352.
A new indole alkaloid, 11,12-dimethoxyhenningsamine (1), was isolated from the roots of Strychnos cathayensis, together with 19 known compounds. The structure of this new compound was determined through spectroscopic and mass-spectrometric analyses. Among the isolated compounds, 11-methoxyhenningsamine (3) and aesculetin dimethyl ether (4) exhibited potent inhibition (IC(50)<5.5 mug/ml) on superoxide-anion generation and elastase release by human neutrophils in response to fMet-Leu-Phe/cytochalasin B.
