Maitotoxin Safety Profile

A poison by intraperitoneal route. When heated to decomposition it emits toxic vapors of SOx.

Maitotoxin Specification

Maitotoxin (CAS NO.59392-53-9) is an extremely potent toxin produced by Gambierdiscus toxicus, a dinoflagellate species. Maitotoxin is so potent that it has been demonstrated that an intraperitoneal injection of 0.13 µg/kg was lethal in mice.Maitotoxin was named from the ciguateric fish Ctenochaetus striatus—called “maito” in Tahiti—from which maitotoxin was isolated for the first time - later it was shown that maitotoxin is actually produced by Gambierdiscus toxicus.

 Maitotoxin is known to activate cytosolic calcium-activated proteases calpain-1 and calpain-2, contributing to necrosis. The toxicity of maitotoxin to mice is the highest in nonprotein toxins: the LD50 is 50 ng/kg.The molecule itself exists as a system of 32 fused rings. It is one of the largest and most complex non-protein, non-polysaccharide molecules produced by an organism.
