Synthesis of the ABC Fragment of the Pectenotoxins

open access: yes, 2005
A highly stereocontrolled synthesis of the C1−C16 ABC spiroacetal-containing fragment 5 of PTX7 (4) has been achieved. Appendage of the C ring to the AB fragment involved Wittig reaction of spiroacetal aldehyde 8 with a stabilized ylide 9 followed by ...

Characterization of F-actin depolymerization as a major toxic event induced by pectenotoxin-6 in neuroblastoma cells

open access: yes, 2002
Pectenotoxins are a group of marine toxins produced by dinoflagellates and formerly included within the group of diarrhetic shellfish poison or toxins (DSP or DST) because of their physico-chemical properties. However, toxicological data on pectenotoxins

Studies of polyether toxins in the marine phytoplankton, Dinophysis acuta, in Ireland using multiple tandem mass spectrometry

open access: yes, 2004
Diarretic shellfish poisoning (DSP) is a toxic syndrome associated with the consumption of bivalve molluscs. The DSP toxins are polyether compounds, which include okadaic acid (OA), dinophysistoxins (DTXs), pectenotoxins (PTXs) and pectenotoxin seco ...

Enzymatic hydrolysis of the acylesters of shellfish toxins for use in routine monitoring

open access: yes
Toxins responsible for incidents of shellfish poisoning, including okadaic acid (OA), dinophysistoxins-1 and -2 (DTX1, DTX2), pectenotoxins, brevetoxins and spirolides can occur as acyl esters in plankton and shellfish creating complications during ...
