Effects of marine phycotoxin dinophysistoxin-1 on the growth and cell cycle of Isochrysis galbana

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2023
The phycotoxin dinophysistoxins are widely distributed in the global marine environments and potentially threaten marine organisms and human health. The mechanism of the dinophysistoxin toxicity in inhibiting the growth of microalgae is less well understood.

Direct evidence of transformation of dinophysistoxin-1 to 7-O-acyl-dinophysistoxin-1 (dinophysistoxin-3) in the scallop Patinopecten yessoensis

Toxicon, 1999
Non-toxic scallops Patinopecten yessoensis were reared for 5 days with the toxic dinoflagellate Dinophysis fortii sampled from the sea. The total cell number ingested by five scallops during the feeding experiment was approximately 682 x 10(3). Okadaic acid (OA), dinophysistoxin-1 (DTX1) and esterified toxins of OA and DTX1 in D.

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

Toxicon, 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.

METABOLIC TRANSFORMATION OF DINOPHYSISTOXIN-3 INTO DINOPHYSISTOXIN-1 CAUSES HUMAN INTOXICATION BY CONSUMPTION OF O-ACYL-DERIVATIVES DINOPHYSISTOXINS CONTAMINATED SHELLFISH

open access: yesJournal of Toxicological Sciences, 2005
This paper describes for the first time a massive intoxication episode due to consumption of shellfish contaminated with 7-O-acyl-derivative dinophysistoxin-1, named Dinophysistoxin-3 (DTX-3). 7-O-acyl-derivative dinophysistoxin-1, a compound recently described in the literature, was found in shellfish samples collected in the Chilean Patagonia fjords.

Aqueous photodegradation of okadaic acid and dinophysistoxin-1: Persistence, kinetics, photoproducts, pathways, and toxicity evaluation

Science of The Total Environment, 2020
Diarrhetic shellfish poisoning (DSP) toxins are a class of natural organic contaminants that pose a serious threat not only to marine ecosystems and fisheries but also to human health. They are widely distributed in coastal and offshore waters around the world.
