Acetylcholine esterase, experiment with

Biosynthesis The biosynthesis of the L. a. has not been completely elucidated. Since Lycopodium species cannot or can only be cultivated with difficulty, tracer experiments must be performed at the natural locations. It is certain that the biogenetic building blocks for the complex ring systems are lysine and acetate. Pharmacological activity The L. a. are moderately toxic. Some L. a. are purported to be potent inhibitors of acetylcholine esterase. Huperzine A has attracted attention on account of its stimulating effect on learning and memory behavior in laboratory animals. In Chinese traditional medicine various Lycopodium species are used to treat skin diseases and as a tonic.
