Anabaseine

[2] Anabaseine causes paralysis in crustaceans and insects, but not in vertebrates, presumably by acting as an agonist on peripheral neuromuscular nicotinic acetylcholine receptors.

It can exist in three forms at physiological pH: a ketone, imine, or iminium structure.

This product then is decarboxylated, undergoes a ring closure, and amide hydrolysis to form anabaseine.Additional synthetic strategies have since been developed by Bloom,[5] Zoltewicz,[6] Smith,[7] and Villemin.

[8] Due to anabaseine’s fairly non-specific binding to nicotinic acetylcholine receptors, the molecule was largely discarded as a useful tool in research or medicine.

[9] Moreover, the modification of the anabaseine pyridine nucleus led to the obtainment of new derivatives endowed with binding and functional selectivity for the α3β4 nicotinic acetylcholine receptor subtype.
