Tetrodotoxin, a Potential Drug for Neuropathic and Cancer Pain Relief?

open access: yesToxins, 2021
Tetrodotoxin (TTX) is a potent neurotoxin found mainly in puffer fish and other marine and terrestrial animals. TTX blocks voltage-gated sodium channels (VGSCs) which are typically classified as TTX-sensitive or TTX-resistant channels.

Tetrodotoxins in Ribbon Worms Cephalothrix cf. simula and Kulikovia alborostrata from Peter the Great Bay, Sea of Japan

open access: yesToxins, 2022
Tetrodotoxin, an extremely potent low-molecular-weight neurotoxin, and its analogues (TTXs) are widely distributed in aquatic and terrestrial ecosystems. Most investigations concerning TTXs have been conducted mainly on puffer fish, octopus, and mollusks,

6-Nitrodopamine Is the Most Potent Endogenous Positive Inotropic Agent in the Isolated Rat Heart

open access: yesLife, 2023
Background: 6-nitrodopamine released from rat isolated atria exerts positive chronotropic action, being more potent than noradrenaline, adrenaline, and dopamine.

From Poison to Promise: The Evolution of Tetrodotoxin and Its Potential as a Therapeutic

open access: yesToxins, 2021
Tetrodotoxin (TTX) is a potent neurotoxin that was first identified in pufferfish but has since been isolated from an array of taxa that host TTX-producing bacteria.

The Structural Basis and Functional Consequences of Interactions Between Tetrodotoxin and Voltage-Gated Sodium Channels

open access: yesMarine Drugs, 2006
: Tetrodotoxin (TTX) is a highly specific blocker of voltage-gated sodium channels. The dissociation constant of block varies with different channel isoforms.

In Silico Analysis of Tetrodotoxin Binding in Voltage-Gated Sodium Ion Channels from Toxin-Resistant Animal Lineages

open access: yesMarine Drugs, 2022
Multiple animal species have evolved resistance to the neurotoxin tetrodotoxin (TTX) through changes in voltage-gated sodium ion channels (VGSCs). Amino acid substitutions in TTX-resistant lineages appear to be positionally convergent with changes in ...

Tetrodotoxin Concentrations in Pleurobranchaea maculata: Temporal, Spatial and Individual Variability from New Zealand Populations

open access: yesMarine Drugs, 2012
Tetrodotoxin (TTX) is a potent neurotoxin that has been identified in a range of phylogenetically unrelated marine and terrestrial organisms. Tetrodotoxin was recently detected in New Zealand in Pleurobranchaea maculata (the grey side-gilled sea slug ...

Does Ocean Sunfish Mola spp. (Tetraodontiformes: Molidae) Represent a Risk for Tetrodotoxin Poisoning in the Portuguese Coast?

open access: yesMarine Drugs, 2022
Tetrodotoxin (TTX) is a potent neurotoxin naturally occurring in terrestrial and marine organisms such as pufferfish. Due to the risk of TTX poisoning, fish of Tetraodontidae family and other puffer-related species must not be placed in the EU markets ...

First Detection of Tetrodotoxins in the Cotylean Flatworm Prosthiostomum trilineatum

open access: yesMarine Drugs, 2021
Several polyclad flatworm species are known to contain high levels of tetrodotoxin (TTX), but currently TTX-bearing flatworms seem to be restricted to specific Planocera lineages belonging to the suborder Acotylea.

Tetrodotoxin. VII. On the Structures of Tetrodotoxin and its Derivatives

open access: yesChemical and Pharmaceutical Bulletin, 1964
The structures of both tetrodonic acid hydrobromide and 6, 11-diacetylanhydrotetrodotoxin hydroiodide were established by chemical and X-ray crystallographical research. Based upon structures of both these salts and upon other chemical information, we determined that tetrodotoxin and anhydrotetrodotoxin have zwitterionic hemilactal structures.
