A Structural Basis for Regulation of Actin Polymerization by Pectenotoxins [PDF]

Journal of Molecular Biology, 2007
(PTXs) are polyether macrolides found in certain dinoflagellates, sponges and shellfish, and have been associated with diarrhetic shellfish poisoning. In addition to their in vivo toxicity, some PTXs are potently cytotoxic in human cancer cell lines.

Function-Oriented Studies Targeting Pectenotoxin 2: Synthesis of the GH-Ring System and a Structurally Simplified Macrolactone

Organic Letters, 2017
A chemical foundation for function-oriented studies of pectenotoxin 2 (PTX2) is described. A synthesis of the bicyclic GH-system, and the design and synthesis of a PTX2-analogue, is presented.

A THEORETICAL ESTIMATION OF EXPOSURE TO SHELLFISH TOXINS OF DIFFERENT POPULATION GROUPS IN BULGARIA

Archives of the Balkan Medical Union, 2021
Introduction. Shellfish poisoning could be caused by ingestion of shellfish contaminated by bacteria, viruses, heavy metals, pesticides, marine biotoxins etc. The objective of the study was to determine the theoretical human exposure to shellfish toxins

Novel synthetic routes towards trans-THFs and application towards the FG fragment of pectenotoxin-4 [PDF]

, 2013
trans-2,5-Disubstituted tetrahydrofurans (THFs) are a common structural motif in a multitude of biologically active natural products. This thesis explores new synthetic routes for their synthesis and subsequent application towards the C31-40 fragment of ...

LC-MS/MS method for the detection of multiple classes of shellfish toxins

Czech Journal of Food Sciences, 2019
Marine shellfish toxins are seafood safety problems of global concern. Herein the analysis of six shellfish toxins, regulated by European Union, with one single run by LC-MS/MS with acidic mobile phase was developed.

A Screening Tool for the Direct Analysis of Marine and Freshwater Phycotoxins in Organic SPATT Extracts from the Chesapeake Bay

Toxins, 2020
Many detection methods for phycotoxins, bioactive compounds produced by harmful algae, focus on one compound or a class of related compounds. Multiple harmful algal species often co-occur in the environment, however, emphasizing the need to analyze for ...
