Tetrodotoxin belongs to the amino-perhydroquinazoline type compounds, which is a kind of toxic and powerful neurotoxin. Tetrodotoxin has a local stimulating effect on the intestinal tract, and after absorption, it rapidly acts on the nerve endings and nerve centers, which can block the sodium ion channels of the nerve excitation membrane with high selectivity and high affinity, hindering the nerve conduction, thus causing nerve paralysis and death.
