Guanitoxin (GNT), formerly known as anatoxin-a(S) "Salivary"^[a],^[1] is a naturally occurring cyanotoxin commonly isolated from cyanobacteria (specifically of the genus Anabaena). It is a potent covalent acetylcholinesterase inhibitor, and thus a potent rapid acting neurotoxin which in cases of severe exposure can lead to death. Guanitoxin was first structurally characterized in 1989, and consists of a cyclic N-hydroxyguanidine organophosphate with a phosphate ester moiety.^[2]
