The fawcettimine class of Lycopodium alkaloids consists of over 60 natural products. Typically, these tetracyclic compounds contain a single quaternary carbon center and are derived biosynthetically from the lycopodane core through an oxidative rearrangement reaction. In 1959, the first member of this class, fawcettimine (1), was isolated by Burnell in the Blue Mountain Range of Jamaica. Inubus...

Complanadines A and B (1 and 2, Scheme 1) are dimeric Lycopodium alkaloids from the lycodine family that possess significant activity for stimulating nerve growth factor (NGF) production in human glial cells. 2] As such, 1 and 2 are of interest as potential small-molecule leads for the treatment of neurodegenerative diseases, such as Alzheimer s disease, as well as adjuvants for the regeneratio...
