Popis

General description

Reversibly blocks Na⁺ channels, which are essential for the propagation of impulses in excitable membranes. Useful as a marker of Na⁺ channels in excitable tissues. Inhibits the release of glutamate via Na+-dependent glutamate transporter and prevents veratradine-induced intracellular Ca²⁺ accumulation (IC₅₀ = 63 nM).

Application

Tetrodotoxin, Fugu sp., CAS 18660-81-6, is a reversible blocker of Na+ channels. Inhibits the release of glutamate via Na+-dependent glutamate transporter.

Biochem/physiol Actions
