Lyconadins D and E, and complanadine E, new Lycopodium alkaloids from Lycopodium complanatum

Three new Lycopodium alkaloids, lyconadins D (1) and E (2), and complanadine E (3), were isolated from the club moss Lycopodium complanatum. Lyconadin D (1) was the first example of fastigiatine-type alkaloid isolated from Lycopodium complanatum. The structures and relative stereochemistry of 1–3 were elucidated on the basis of spectroscopic data. Complanadine E (3) enhanced mRNA expression for NGF.
