(1R,5R,6R,7R,9S,11R,12R,13S,14S)-14-(hydroxymethyl)-3-imino-8,10-dioxa-2,4-diazatetracyclo[7.3.1.1(7,11).0(1,6)]tetradecane-5,9,12,13,14-pentol
Tetrodotoxin is a quinazoline alkaloid that is a marine toxin isolated from fish such as puffer fish. It has been shown to exhibit potential neutotoxicity due to its ability to block voltage-gated sodium channels. It has a role as a voltage-gated sodium channel blocker, a neurotoxin, a marine metabolite, an animal metabolite and a bacterial metabolite. It is a quinazoline alkaloid, an azatetracycloalkane and an oxatetracycloalkane. It is a conjugate base of a tetrodotoxin(1+).
