The Chemistry and Biology of the Tetrodotoxin Natural Product Family

Angewandte Chemie International Edition, EarlyView.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.
