Determination of brevetoxin in recent marine sediments [PDF]

Chemosphere, 2008
Harmful algal blooms (HAB) of Karenia brevis (K. brevis) produce a suite of lipid soluble polyether brevetoxins, known to cause environmental, health and economic ill effects. There is evidence that K. brevis has increased in abundance over the past 50 years, but the dataset is incomplete.

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 ...

Brevetoxin derivatives that inhibit toxin activity [PDF]

Chemistry & Biology, 2000
The brevetoxins are marine neurotoxins that interfere with the normal functions of the voltage-gated Na(+) channel. We have identified two brevetoxin derivatives that do not exhibit pharmacological properties typical of the brevetoxins and that function as brevetoxin antagonists.PbTx-3 and benzoyl-PbTx-3 elicited Na(+) channel openings during steady ...

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.

Characterization of marine aerosol for assessment of human exposure to Brevetoxins [PDF]

, 2005
Red tides in the Gulf of Mexico are commonly formed by the fish-killing dinoflagellate Karenia brevis, which produces nine potent polyether brevetoxins (PbTxs).

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.

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.
