Beschreibung
Tetrodotoxin (TTX) is a selective sodium channel blocker
nonprotein heat-stable toxin. The mechanism of toxicity is
through the blockage of fast voltage-gated sodium channels.
The consumption of toxic amounts of TTX results primarily in
neurologic and gastrointestinal signs and symptoms. TTX is
widely distributed in marine taxa such as pufferfish and
porcupine fish (suborders of the Tetraodontiformes order),
salamanders of the family Salamandridae, Central American
frogs (genus Atelopus), shellfish, starfish, crabs, and some
species of ribbonworm and octopus. However, in terrestrial
taxa, it is limited to a single class of vertebrates (Amphibia).
TTX is now known to be produced not by puffer but by
bacteria, and reaches various species of animals via food chain.
Chemische Eigenschaften
white powder
Verwenden
Tetrodotoxin is a highly selective, reversible sodium channel blocker.
Definition
ChEBI: A quinazoline alkaloid that is a marine toxin isolated from fish such as puffer fish. It has been shown to exhibit potential neutotoxicity due to its ability to block voltage-gated sodium channels.
Biologische Aktivität
Selective inhibitor of Na + channel conductance. Binding is reversible and of high affinity (K d = 1-10 nM). Blocks in a use-dependent manner.
Sicherheitsprofil
Poison by ingestion,
intraperitoneal, subcutaneous, and
intravenous routes. When heated to
decomposition it emits toxic fumes of Nox.
