Structure Activity Relationship of Brevenal Hydrazide Derivatives

open access: yesMarine 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

Acute Effects of Brevetoxin-3 Administered via Oral Gavage to Mice

open access: yesMarine Drugs, 2023
Brevetoxins (BTXs) constitute a family of lipid-soluble toxic cyclic polyethers mainly produced by Karenia brevis, which is the main vector for a foodborne syndrome known as neurotoxic shellfish poisoning (NSP) in humans.

Brevenal inhibits pacific ciguatoxin-1B-induced neurosecretion from bovine chromaffin cells.

open access: yesPLoS 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

open access: yesMarine 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.

Convergent, Stereoselective Synthesis of the GHIJ Fragment of Brevetoxin A

open access: yes, 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 ...

Characterization of Interaction Between Brevetoxin and Its Native Receptor and Identification of the Role of Brevetoxin in Karenia brevis [PDF]

open access: yes, 2016
Algae are important to marine and fresh-water ecosystems. However, some species of algae are harmful or even toxic. They can consume oxygen or block sunlight that is essential for other organisms to live. Indeed, some algae blooms can produce toxins that

Potential Threats Posed by New or Emerging Marine Biotoxins in UK Waters and Examination of Detection Methodology Used in Their Control: Brevetoxins

open access: yesMarine Drugs, 2015
Regular occurrence of brevetoxin-producing toxic phytoplankton in commercial shellfishery areas poses a significant risk to shellfish consumer health. Brevetoxins and their causative toxic phytoplankton are more limited in their global distribution than

Fluorescent Receptor Binding Assay for Detecting Ciguatoxins in Fish. [PDF]

open access: yesPLoS 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)).

Profiling of Brevetoxin Metabolites Produced by Karenia brevis 165 Based on Liquid Chromatography-Mass Spectrometry

open access: yesToxins, 2021
In this study, Karenia brevis 165 (K. brevis 165), a Chinese strain, was used to research brevetoxin (BTX) metabolites. The sample pretreatment method for the enrichment of BTX metabolites in an algal culture medium was improved here.

Chemodiversity of Brevetoxins and Other Potentially Toxic Metabolites Produced by Karenia spp. and Their Metabolic Products in Marine Organisms

open access: yesMarine Drugs, 2021
In recent decades, more than 130 potentially toxic metabolites originating from dinoflagellate species belonging to the genus Karenia or metabolized by marine organisms have been described.
