Route of metabolization and detoxication of paralytic shellfish toxins in humans

Toxicon, 2010
Paralytic shellfish toxins (PST) are a collection of over 26 structurally related imidazoline guanidinium derivatives produced by marine dinoflagellates and freshwater cyanobacteria. Glucuronidation of drugs by UDP-glucuronosyltransferase (UGT) is the major phase II conjugation reaction in mammalian liver.

Neurotoxins from Marine Dinoflagellates: A Brief Review

Marine Drugs, 2008
Dinoflagellates are not only important marine primary producers and grazers, but also the major causative agents of harmful algal blooms. It has been reported that many dinoflagellate species can produce various natural toxins.

Paralytic shellfish poisoning due to ingestion of contaminated mussels: A 2018 case report in Caparica (Portugal)

Toxicon: X, 2019
In Portugal, the potent paralytic shellfish toxins (PSTs) have appeared irregularly since the onset of a national monitoring program for marine biotoxins in 1986. In years where high contamination levels were attained in bivalves, sporadic cases of human

Liquid Chromatographic-Fluorometric Analysis of Paralytic Shellfish Toxins

Agricultural and Biological Chemistry, 1984
Alkaline oxidation of paralytic shellfish toxins with ten-butyl hydroperoxide yielded highly fluorescent derivatives. Even gonyautoxins I and IV and neosaxitoxin, which were nonfluorescing by previously proposed hydrogen peroxide oxidations, were successfully converted to fluorescent compounds.

Simultaneous presence of Paralytic and Diarrheic Shellfish Poisoning toxins in Mytilus chilensis samples collected in the Chiloe Island, Austral Chilean Fjords

Biological Research, 2004
The study shown here provides the first indisputable evidence that shellfish can be contaminated with Paralytic Shellfish Poisoning (PSP) and Diarrheic Shellfish Poisoning (DSP) toxins during the summer season in the Southern Chilean fjords. Quantitative

Paralytic Toxins in the Dinoflagellate Gonyaulax excavata and in Shellfish

, 1978
Paralytic toxins were examined quantitatively in a culture of Gonyaulax excavata and in shellfish by the standard mouse bioassay and by an alkaline peroxide oxidation–fluorometric assay for saxitoxin (STX).

LC-HRMSn versus LC-MS/MS of Paralytic Shellfish Poisoning toxins and tetrodotoxin in microalgae and seafood

, 2017
Paralytic shellfish poisoning toxins (PST) are a group of neurotoxins produced by dinoflagellate belonging to genera Alexandrium and Gymnodinium. The accumulation of these toxins in seafood represent a major concern to humans since following ingestion of

Investigation into Paralytic Shellfish Toxins and Microcystins in Seabirds from Portugal

Toxins
Microalgae form the basis of marine food webs, essential in sustaining top predators including seabirds. However, certain species of microalgae synthesize biotoxins, which can accumulate in shellfish and fish and may cause harm to marine animals feeding ...
