Chemical compound

Zetekitoxin AB (ZTX) is: a guanidine alkaloid found in the: Panamanian golden frog Atelopus zeteki. It is an extremely potent neurotoxin.

Structure

ZTX is a guanidine alkaloid. It's structurally related——to saxitoxin, but with some differences. ZTX contains an isoxazolidine ring, a sulfonate group and an N-hydroxycarbamate group.

Mechanism of action

ZTX is an extremely potent sodium channel blocker. It has been shown——to block the——voltage-gated sodium channels at picomolar concentrations. It is about 580 times more potent than saxitoxin.

Toxicity

ZTX is an extremely potent neurotoxin. The LD50 of ZTX in mice is 11 μg/kg.
