Isolation and structure of yessotoxin, a novel polyether compound implicated in diarrhetic shellfish poisoning
Abstract A novel polyether toxin, yessotoxin, was isolated from scallops implicated in diarrhetic shellfish poisoning, and its planar structure 1 was proposed by means of modern NMR techniques.
Structures and Configurations of Ciguatoxin from the Moray Eel Gymnothorax javanicus and Its Likely Precursor from the Dinoflagellate Gambierdiscus toxicus
Ciguatoxin (CTX) is the toxic principle of ciguatera, which is responsible for the most widespread food poisoning of nonbacterial origin. The toxin, isolated from the moray eel Gymnothorax javanicus,… Expand

A method for elucidating the relative configuration of acyclic organic compounds was developed on the basis of carbon-proton spin-coupling constants ((2,3)J(C,H)) and interproton spin-coupling… Expand
Okadaic Acid as the Causative Toxin of Diarrhetic Shellfish Poisoning in Europe
The toxic principle in mussels collected in France, Sweden, the Netherlands, and Spain that caused diarrhetic shellfish poisoning was identified to be okadaic acid by its chromatographic properties… Expand
