title: Lycoparins A-C, new alkaloids from Lycopodium casuarinoides inhibiting acetylcholinesterase.
abstract: Three new Lycopodium alkaloids, lycoparins A-C (1-3), have been isolated from the club moss Lycopodium casuarinoides. Structures and stereochemistry of 1-3 were elucidated on the basis of 2D NMR correlations. Lycoparins C (3) exhibited an inhibitory activity against acetylcholinesterase, while lycoparins A (1) and B (2) did not show activity.
