Further Insights into Brevetoxin Metabolism by de Novo Radiolabeling

Toxins, 2014
The toxic dinoflagellate Karenia brevis, responsible for early harmful algal blooms in the Gulf of Mexico, produces many secondary metabolites, including potent neurotoxins called brevetoxins (PbTx).

Binding of brevetoxins and ciguatoxin to the voltage-sensitive sodium channel and conformational analysis of brevetoxin B

Toxicon, 1992
The marine toxins known generically as brevetoxins, as well as their structural relative ciguatoxin, are known as polyether ladder toxins, and bind uniquely to site 5 of the voltage-sensitive sodium channel. Rat brain synaptosome binding data show similarities in binding affinity for brevetoxins having the same structural (ladder) backbone, but ...

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

Lessening the Hazards of Florida Red Tides: A Common Sense Approach

Frontiers in Marine Science, 2020
In the Gulf of Mexico, especially along the southwest Florida coast, blooms of the dinoflagellate Karenia brevis are a coastal natural hazard. The organism produces a potent class of toxins, known as brevetoxins, which are released following cell lysis ...

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...

Pacific-Ciguatoxin-2 and Brevetoxin-1 Induce the Sensitization of Sensory Receptors Mediating Pain and Pruritus in Sensory Neurons

Marine Drugs, 2021
Ciguatera fish poisoning (CFP) and neurotoxic shellfish poisoning syndromes are induced by the consumption of seafood contaminated by ciguatoxins and brevetoxins.

Chronic and punctuated changes in subtropical reef fish assemblages

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Understanding temporal changes in marine biodiversity is crucial for managing and conserving reef ecosystems in the face of global environmental shifts. Although biodiversity changes at global and regional scales often differ, the role of subtropical systems in these patterns has been relatively understudied until recently.

Vectors of Brevetoxins to Marine Mammals [PDF]

, 2008
Mass mortalities of Florida manatees (Trichechus manatus latirostris) and bottlenose dolphins (Tursiops truncatus) have been attributed to brevetoxins produced by the Florida red tide dinoflagellate Karenia brevis.

Florida red tide toxins (brevetoxins) and longitudinal respiratory effects in asthmatics

, 2011
▶ Brevetoxins from Florida red tide ( Karenia brevis bloom) can be aerosolized. ▶ Aerosolized brevetoxins can cause acute and subacute effects in asthmatics. ▶ Unstable asthmatics are particularly susceptible to aerosolized brevetoxin exposures.
