Application Notes

Eserine (physostigmine) was isolated from the Calabar bean in 1878 and its structure first elucidated in 1925 and subsequently revised in 1973. Eserine inhibits acetylcholinesterase, indirectly stimulating both nicotinic and muscarinic receptors due to the consequential increase in available acetylcholine at the synapse. Eserine acts allosterically as a noncompetitive sensitizer of acetylcholine in the rat heart.
