Carinatumins A–C, new alkaloids from Lycopodium carinatum inhibiting acetylcholinesterase

Three new Lycopodium alkaloids, carinatumins A–C (1–3), have been isolated from the club moss Lycopodium carinatum. Structures and stereochemistry of 1–3 were elucidated on the basis of 2D NMR correlations. Carinatumins A (1) and B (2) exhibited a potent inhibitory activity against acetylcholinesterase.
