Common Name |
Saxitoxin
Description |
Saxitoxin is a paralytic poison from Alaska butter clams (Saxidomus giganteus), toxic mussels (Mytilus californianus), the plankton Gonyaliax cantenella and Protogonyaliax tamarensis. Causal agent of paralytic shellfish poisoning. Saxitoxin (STX) is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp., Gymnodinium sp., Pyrodinium sp.) and cyanobacteria (Anabaena sp., some Aphanizomenon species, Cylindrospermopsis sp., Lyngbya sp., Planktothrix sp.). Ingestion of saxitoxin (usually through shellfish contaminated by toxic algal blooms) is responsible for the human illness known as paralytic shellfish poisoning (PSP). (Wikipedia) Saxitoxin has been shown to exhibit emetic function (PMID 17482032 ).Saxitoxin belongs to the family of Saxitoxins, Gonyautoxins, and Derivatives. These are compounds whose structure is based on a 2,6-diamino-4-methyl-pyrrolo[1,2-c]purin-10-ol skeleton.
