Marine neurotoxins: Ingestible toxins

Current Treatment Options in Neurology, 2004
Fish and shellfish account for a significant portion of food-borne illnesses throughout the world. In general, three classes of diseases result from seafood consumption--intoxication, allergies, and infections. In this review, the authors discuss several seafood-borne toxins, including domoic acid, which acts on the central nervous system. In addition,

Partial blockade of human voltage-dependent sodium channels by the marine toxins azaspiracids.

Chemical Research in Toxicology, 2020
Azaspiracid toxins were first identified at the end of the last century in Irish mussels and during the last two decades considerable several cytotoxic and neurotoxic effects caused by these toxins have been described.

Determination of lipophilic marine toxins in fresh and processed shellfish using modified QuEChERS and ultra-high-performance liquid chromatography-tandem mass spectrometry.

Food Chemistry, 2019
A simple QuEChERS method coupled with ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was developed to improve the extraction efficiency of lipophilic marine toxins (yessotoxins, dinophysistoxins, okadaic acid ...

Chemosensors for the Marine Toxin Saxitoxin

Journal of the American Chemical Society, 2002
Eleven anthracylmethyl crown ethers have been synthesized and evaluated as fluorescence sensors for the marine toxin saxitoxin. Fluorescence enhancement data are consistent with a 1:1 binding complex for all crowns. The binding constants are in the range of 10(4) M(-)(1) in ammonium phosphate buffer (pH 7.1) in 80% ethanol solvent.

Outbreaks, toxicology, and analytical methods of marine toxins in seafood

Current Opinion in Food Science, 2018
The consumption of seafood with marine toxins can cause intoxications of varied severity and often-fatal symptoms which may appear in few minutes. Marine toxins are resistant to cooking and freezing, posing a serious hazard to public health.

A Perspective on the Toxicology of Marine Toxins

Chemical Research in Toxicology, 2012
Although there has been much progress with regard to marine toxins from dinoflagellates, much remains to be done. Because these compounds are a seafood consumer risk, the demands cover from legislative to scientific aspects. Legislation is required for all new toxins that appear in the coasts.

[Marine toxins].

Wiener medizinische Wochenschrift (1946), 2001
The consumption of seafood, which is contaminated by toxines of red tides, is a common cause of disease in tropic regions. The most important diseases, which are caused by red tides are Paralytic Shellfish Poisoning (PSP), Diarrhetic Shellfish Poisoning (DSP), Neurotoxic Shellfish Poisoning (NSP), Amnesic Shellfish Poisoning (ASP), Ciguatera Fish ...

Marine Toxins and Nonmarine Toxins:  Convergence or Symbiotic Organisms?

Journal of Natural Products, 2004
Bioactive marine natural products occur only rarely in nonmarine sources. The converse also is true. Divergent evolutionary pathways for the biosynthesis of bioactive secondary metabolites seem to be the rule. Marine biosynthetic pathways lead to a wide variety of different structural classes, among which polyethers, macrolides, terpenes, unusual amino
