A novel approach to the synthesis of the FG fragment of pectenotoxin-4 [PDF]

, 2012
The cobalt-catalysed oxidative cyclisation of 5-hydroxy alkenes has been demonstrated to be a powerful synthetic tool for the formation of trans-THFs with excellent diastereoselectivity.

Small-Scale Biophysical Interactions and Dinophysis Blooms: Case Study in a Strongly Stratified Chilean Fjord

Journal of Marine Science and Engineering
Diarrhetic shellfish poisoning (DSP) toxins and pectenotoxins (PTXs) produced by endemic species of Dinophysis, mainly D. acuta and D. acuminata, threaten public health and negatively impact the shellfish industry worldwide.

Diversity of eukaryote plankton and phycotoxins along the West Kalaallit Nunaat (Greenland) coast

Frontiers in Marine Science
The West Kallaallit Nunaat (Greenland) coast, characterized by a variety of fjords, bays, and channels influenced by glacier melting and Atlantic and Arctic waters, is one of the most affected ecosystems by climate change.

Profiles and levels of fatty acid esters of okadaic acid group toxins and pectenotoxins during toxin depuration, Part I: Brown crab (Cancer pagurus)

, 2008
In 2002, two outbreaks of diarrhetic shellfish poisoning (DSP) occurred in Norway, which was later confirmed to be caused by the consumption of brown crab (Cancer pagurus) contaminated predominantly by esters of okadaic acid (OA) after feeding on toxic ...

Synthetic Studies Towards Shellfish Toxins Containing Spiroacetal Units

, 2007
The synthesis of the ABC spiroacetal-containing fragment of the marine biotoxins, the pectenotoxins (PTXs), is described. The synthetic strategy involves appendage of the highly substituted tetrahydofuran C ring to the AB spiroacetal unit via ...

First identification of a C9-diol-ester of okadaic acid in Dinophysis acuta from Galician Rías Baixas (NW Spain)

, 2018
Dinoflagellates of the genus Dinophysis produce okadaic acid (OA) and analogues. Cultures of a strain of Dinophysis acuta isolated from the Galician Rías contained high levels of pectenotoxins but little OA. Isomeric forms of the latter were suspected as

Liquid chromatography - tandem mass spectrometry for the detection of marine lipophilic toxins under alkaline conditions

, 2009
A new LC-MS/MS method for the separation and detection of the most prominent marine lipophilic toxin groups comprising okadaic acid, dinophysistoxins, yessotoxins, azaspiracids, pectenotoxins, spirolides and some okadaic acid fatty acid esters has been ...
