“Algal-dromes”: a novel conceptual approach to illness in humans exposed to harmful algal bloom toxins [PDF]

open access: yesFrontiers in Toxicology
Although adverse health effects from harmful algal bloom (HAB) toxins have been described since antiquity, the true worldwide incidence and disease burden has yet to be defined.

Toxins of Okadaic Acid-Group Increase Malignant Properties in Cells of Colon Cancer [PDF]

open access: yesToxins, 2020
Diarrhetic shellfish poisoning (DSP) is a syndrome caused by the intake of shellfish contaminated with a group of lipophilic and thermostable toxins, which consists of okadaic acid (OA), dinophysistoxin-1 (DTX-1) and dinophysistoxin-2 (DTX-2).

Comparison of dinophysistoxin-1 and esterified dinophysistoxin-1 (dinophysistoxin-3) contents in the scallop Patinopecten yessoensis and the mussel Mytilus galloprovincialis

open access: yesToxicon, 2001
Okadaic acid (OA) homologues in toxic dinoflagellate Dinophysis fortii, scallops Patinopecten yessoensis and mussels Mytilus galloprovincialis collected at the same site in Mutsu Bay, Japan were determined by high-performance liquid chromatography fluorescence detection (HPLC-FLD) as their 9-anthryldiazomethane (ADAM) derivatives.

Risk Assessment of Pectenotoxins in New Zealand Bivalve Molluscan Shellfish, 2009–2019

open access: yesToxins, 2020
Pectenotoxins (PTXs) are produced by Dinophysis spp., along with okadaic acid, dinophysistoxin 1, and dinophysistoxin 2. The okadaic acid group toxins cause diarrhetic shellfish poisoning (DSP), so are therefore regulated.

Dinophysis acuta in Scottish Coastal Waters and Its Influence on Diarrhetic Shellfish Toxin Profiles

open access: yesToxins, 2018
Diarrhetic shellfish toxins produced by the dinoflagellate genus Dinophysis are a major problem for the shellfish industry worldwide. Separate species of the genus have been associated with the production of different analogues of the okadaic acid group ...

Structure–Activity Relationship Studies Using Natural and Synthetic Okadaic Acid/Dinophysistoxin Toxins [PDF]

open access: yesMarine Drugs, 2016
Okadaic acid (OA) and the closely related dinophysistoxins (DTXs) are algal toxins that accumulate in shellfish and are known serine/threonine protein phosphatase (ser/thr PP) inhibitors.

Quantitation of diarrhetic shellfish poisoning toxins in Chilean Mussel using pyrenyldiazomethane as fluorescent labeling reagent [PDF]

open access: yesBiological Research, 2003
Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disease caused by lipid soluble polyether toxins produced by dinoflagellates and accumulated in shellfish.

First report of diarrheic shellfish toxins in mollusks from Buenos Aires province (Argentina) associated with dinophysis spp.: evidence of okadaic acid, dinophysistoxin-1 and their acylderivatives [PDF]

open access: yesBoletín de la Sociedad Argentina de Botánica, 2012
In January 2010, the toxin-producing dinoflagellates Dinophysis acuminata and D. caudata (10³ cells·l-1) were detected in Mar Azul during routine plankton monitoring in Buenos Aires Province coastal waters, Argentina.

Occurrence and risk assessment of okadaic acid, dinophysistoxin-1, dinophysistoxin-2, and dinophysistoxin-3 in seafood from South Korea. [PDF]

open access: yesEnviron Sci Pollut Res Int, 2023
AbstractThe okadaic acid (OA)-group toxins, including OA, dinophysistoxin-1 (DTX1), dinophysistoxin-2 (DTX2), and dinophysistoxin-3 (DTX3), cause diarrheic shellfish poisoning in humans. To manage OA-group toxins more strictly, Korean regulations were recently revised to consider OA, DTX1, DTX2, and DTX3 combined.

Elucidation of the mass fragmentation pathways of the polyether marine toxins, dinophysistoxins, and identification of isomer discrimination processes

open access: yesRapid Communications in Mass Spectrometry, 2012
RATIONALE Most of the liquid chromatography/mass spectrometry (LC/MS) methods that have been developed for the analysis of Diarrhetic Shellfish Poisoning (DSP) toxins in shellfish and algae samples have been unable to differentiate the isomers okadaic ...
