Spectroscopic ellipsometry methods for brevetoxin detection
Talanta, 2022 The spectroscopic ellipsometry (SE), and attenuated internal reflection spectroscopic ellipsometry (TIRE) are promising methods in label-free biosensing applications. An ellipsometer running under surface plasmon resonance (SPR) conditions has unique advantages over other SPR-based methods in terms of sensitivity and real-time/label-free measurement ...

Synthesis, Modeling, and Biological Evaluation of Analogues of the Semisynthetic Brevetoxin Antagonist β‐Naphthoyl‐Brevetoxin [PDF]
ChemBioChem, 2007 AbstractBrevetoxins are neurotoxic compounds produced by the dinoflagellate Karenia brevis. Extensive blooms induce neurotoxic shellfish poisoning (NSP) and asthma‐like symptoms in humans. β‐naphthoyl‐brevetoxin, the first semisynthetic brevetoxin antagonist, has been defined as the lead compound in the investigation of the mechanisms of ...

Convergent, Stereoselective Synthesis of the GHIJ Fragment of Brevetoxin A
, 2016 A stereoselective synthesis of the GHIJ fragment of brevetoxin A utilizing a convergent assembly strategy is described. Glycolate alkylation, ring-closing metathesis, and Hosomi−Sakurai reactions were central operations in the construction of the G ring ...

Structure Activity Relationship of Brevenal Hydrazide Derivatives
Marine Drugs, 2014 Brevenal is a ladder frame polyether produced by the dinoflagellate Karenia brevis. This organism is also responsible for the production of the neurotoxic compounds known as brevetoxins. Ingestion or inhalation of the brevetoxins leads to adverse effects

Brevenal inhibits pacific ciguatoxin-1B-induced neurosecretion from bovine chromaffin cells.
PLoS ONE, 2008 Ciguatoxins and brevetoxins are neurotoxic cyclic polyether compounds produced by dinoflagellates, which are responsible for ciguatera and neurotoxic shellfish poisoning (NSP) respectively. Recently, brevenal, a natural compound was found to specifically

Marine Neurotoxins’ Effects on Environmental and Human Health: An OMICS Overview
Marine Drugs, 2021 Harmful algal blooms (HAB), and the consequent release of toxic metabolites, can be responsible for seafood poisoning outbreaks. Marine wildlife can accumulate these toxins throughout the food chain, which presents a threat to consumers’ health.

Fluorescent Receptor Binding Assay for Detecting Ciguatoxins in Fish. [PDF]
PLoS ONE, 2016 Ciguatera fish poisoning is an illness suffered by > 50,000 people yearly after consumption of fish containing ciguatoxins (CTXs). One of the current methodologies to detect ciguatoxins in fish is a radiolabeled receptor binding assay (RBA(R)).
