For example, harmful algal blooms produced by Karenia brevis, a marine dinoflagellate, have been reported to produce brevetoxins
that are associated with gastrointestinal and respiratory illnesses (Backer et al.
The influence of some abiotic parameters, as well as the production of brevetoxins
and their analogues were also investigated.
Red tide organisms cause problems for fish because they emit chemicals called brevetoxins
which interfere with the functioning of gills.
05[micro]g/mL), exceeded in potency only by brevetoxins
, unique activators of voltage-sensitive sodium channels bind to specific sites in rat brain synaptosomes.
Karenia brevis red tides, brevetoxins
in the food web, and impacts on natural resources: Decadal advancements.
Tetrazolium-based cell bioassay for neurotoxins active on voltage-sensitive sodium channels: semiautomated assay for saxitoxins, brevetoxins
, and ciguatoxins.
The chemicals of focus are okadaic acid, brevetoxins
, lyngbyatoxin A, caulerpenyne, bryostatins, and isocyano terpenes.
Phycotoxins are covered in alphabetical order and include: azaspiracids, brevetoxins
, domoic acid, pectenotoxins, and yessotoxins.
during a Gymnodinium breve red tide: comparison of sodium channel specific cytotoxicity assay and mouse bioassay for determination of neurotoxic shellfish toxins in shell-fish extracts.
Scientists are working to harness these novel compounds as antidotes to brevetoxins
or even as treatments for unrelated lung diseases, such as cystic fibrosis.
can also be aerosolized by wave action.
