Abstract
Five monoterpene indole alkaloids, mitradiversifoline, with a unique rearranged skeleton, specionoxeine-N(4)-oxide, 7-hydroxyisopaynantheine, 3-dehydropaynantheine, and 3-isopaynantheine-N(4)-oxide, and 10 known ones, were isolated from Mitragyna diversifolia. All the isolates were evaluated for their inhibition of acetylcholinesterase activities, and four showed moderate activities, with IC50 values of 4.1, 5.2, 10.2, and 10.3 μM, respectively.
