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.

Determination of Brevetoxins in Shellfish by the Neuroblastoma Assay [PDF]

Journal of AOAC INTERNATIONAL, 2002
Abstract A neuroblastoma assay for determination of brevetoxins in shellfish was developed together with a method for sample cleanup that allows separation of brevetoxins from most of the components that cause matrix interference in the assay.

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 ...

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 ...

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.

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 ...

Lessons learned from mesocosm experiments with curcumin: Pilot studies of a harmful algal bloom mitigation technique

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Curcumin, a natural plant product derived from Curcuma longa, was assessed as a mitigation technique against the toxic bloom‐forming dinoflagellate Karenia brevis in two mesocosm experiments taking place in 2022 and 2024. In these experiments, curcumin was applied at a dosage of 5 mg L−1 to K.

An ecological framework for microbial metabolites in the ocean ecosystem

Limnology and Oceanography Letters, Volume 10, Issue 5, Page 636-659, September 2025.
Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,

Die Chemie und Biologie der Tetrodotoxin Naturstofffamilie

Angewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Tetrodotoxin ist vor allem als das Gift des Kugelfisches bekannt, einer Delikatesse in der japanischen Küche. Seine Toxizität beruht auf der selektiven Blockade von NaV Kanälen, wie am Beispiel der NaV1.7 Pore dargestellt, wobei das DEKA Motiv hervorgehoben ist, das für die Durchlässigkeit von Natriumionen verantwortlich ist.
