An almost nontoxic tetrodotoxin analog, 5,6,11-trideoxytetrodotoxin, as an odorant for the grass puffer
Y. Noguchi, T. Suzuki, K. Matsutani…·H. Abe
The paper investigates whether grass puffers detect tetrodotoxin (TTX) and finds that they respond to a less toxic TTX analog, 5,6,11-trideoxyTTX, suggesting it may function as an odorant for chemical communication.
