AbstractThe identification of novel tetrodotoxin (TTX,1) analogues would significantly contribute to the elucidation of its biosynthetic pathway. In this study, the first C5–C10 directly bonded TTX analogues, 4,9‐anhydro‐10‐hemiketal‐5‐deoxyTTX (2) and 4,9‐anhydro‐8‐epi‐10‐hemiketal‐5,6,11‐trideoxyTTX (3), were found in the newtCynops ensicauda popeiby

Tetrodotoxin and its analogues profile in nemertean species from the sea of Japan
Toxicon, 2018For the first time search for tetrodotoxin (TTX) and its analogues in the extracts of nemerteans using HPLC-MS/MS was performed. TTX analogues were detected in two nemertean species in addition to TTX: 7 analogues were detected in the extract of Cephalothrix simula, 3 analogues - in the extract 11-norTTX of Kulikovia manchenkoi. Presence of 5-deoxyTTX,

Tetrodotoxin (TTX) is one of the most potent toxin already isolated, which occurs in a wide range of marine as well as terrestrial animals such as in newts and anurans. In this work, the occurrence of TTX and analogues was examined in three brachycephalid species: Brachycephalus ephippium, B. nodoterga and B. pernix using LC-FLD and LC-MS/MS.

The monoclonal antibody against tetrodotoxin (TTX), prepared by Kawatsu et al. (1997), has been used in several TTX-related studies. Herein, we confirmed the quite low cross-reactivity of this antibody to three major TTX analogues in pufferfish using competitive ELISA: 5,6,11-trideoxyTTX (

Brachycephalus ephippium is a diurnal frog, that shows aposematic colouration and inhabits Atlantic forest leaf litter in south-eastern Brazil. The presence of tetrodotoxin (TTX) in the skin, liver and ovaries of B. ephippium was demonstrated. The skin (260 M.U./g) exhibited the highest toxicity followed by liver (177 M.U./g).

Tetrodotoxin (TTX) is a potent neurotoxin naturally found in terrestrial and marine animals targeting the voltage-gated sodium channels. Historically, TTX has raised food safety concerns mainly in the Asian countries due to the consumption of the typical pufferfish-derived delicacy fugu.
