Opis

Opis ogólny

Lipid-soluble polyether marine toxin produced by the red tide dinoflagellate, Ptychodiscus brevis, found along the Gulf Coast of Florida. Voltage-dependent Na⁺ channel activator that causes contractile paralysis in animal models. The excitatory action on nerve and muscle membranes is responsible for a wide spectrum of toxic effects, including massive transmitter release from nerve endings, muscle fasiculation, and ventricular fibrillation. The excitatory action is due to opening of the Na⁺ channels. The toxin does not bind either to the TTX or to the aconitine/veratridine sites.

Lipid-soluble polyether neurotoxin that binds to Na⁺ channels on nerves and muscles causing an excessive influx of Na⁺ across membranes. Binds at site 5 on the voltage-sensitive Na⁺ channel.
