Saxitoxin (STX) is the best-known paralytic shellfish toxin (PST) although other related compounds have been reported such as neosaxitoxin (NSTX) the 11-alpha and 11-beta-O-sulphates of saxitoxin and neosaxitoxin and carbonyl-N-sulphate derivatives of saxitoxin and neosaxitoxin.STX is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp. Gymnodinium sp. Pyrodinium sp.) and cyanobacteria (Anabaena sp. some Aphanizomenon spp. Cylindrospermopsis sp. Lyngbya sp.Planktothrix sp.).
