Ciguatoxin-2 is a diastereomer of ciguatoxin-3

Toxicon, 1993
Ciguatoxin-2, a major ciguatoxin present in the flesh and viscera of ciguateric fishes, has been shown by 1H nuclear magnetic resonance studies (2-dimensional homonuclear Hartman Hahn, nuclear Overhauser effect and decoupling difference experiments) to be a diastereomer of ciguatoxin-3, differing only in stereochemistry at carbon 52 (a quaternary ...

Total Synthesis of Ciguatoxin

Angewandte Chemie, 2009
AbstractEines der Haupttoxine bei Fischvergiftungen, das Ciguatoxin (siehe Struktur), war Ziel einer Totalsynthese. Der Syntheseweg beruht auf der Kupplung dreier Segmente, und die Schlüsselumwandlungen umfassen eine Komplexbildung zwischen Acetylen und Dicobalthexacarbonyl.magnified ...

Ciguatoxin: More Than an Anticholinesterase

Science, 1968
Anticholinesterase action of ciguatoxin has been reported. A study of the pharmacology of the action of the toxin on the respiratory system suggests that additional properties may be involved in the respiratory failure—the usual cause of death in ciguatera poisoning.

Ciguatoxin: Isolation and Chemical Nature

Science, 1967
Ciguatoxin, the agent responsible for ciguatera, a disease produced in humans from ingestion of certain fishes, has been isolated from specimens of the moray eel, Gymnothorax javanicus . The toxin is apparently a lipid containing quaternary nitrogen, hydroxyl, and carbonyl functions.
