HABs Karenia brevis and Pseudo-nitzschia pre- and post-Hurricane Michael [PDF]
Journal of Water and Health, 2023 Increased occurrences of harmful algal blooms (HAB) in the Gulf of Mexico, and even worldwide, yield concern for increases in brevetoxin exposure leading to respiratory illness or even death, highlighting the need for extensive scientific research and ...

Predicting <i>Karenia brevis</i> Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed. [PDF]
GeohealthAbstract Nearly annually, blooms of the dinoflagellate Karenia brevis form along the southwest Florida coast leading to a variety of negative impacts, including respiratory irritation (RI) in humans. To limit these impacts, NOAA's National Centers for Coastal Ocean Science (NCCOS) developed a RI model to provide beach‐goers with a category‐based ...

Synthesis of the A-F Fragment of the Pacific Ciguatoxin CTX3C by Iterative Ring-Closing Metathesis and Tsuji-Trost Allylation. [PDF]
Chemistry, 2023 The fully functionalized A−F ring system of the Pacific ciguatoxin CTX3C suitable for coupling to the I−M fragment of the natural product, has been synthesized from a simple glucal derivative. A six‐step sequence that features ring‐closing metathesis and stereoselective palladium‐mediated allylation has been deployed in an iterative manner to construct

Guidance Level for Brevetoxins in French Shellfish [PDF]
Marine Drugs, 2021 Brevetoxins (BTXs) are marine biotoxins responsible for neurotoxic shellfish poisoning (NSP) after ingestion of contaminated shellfish. NSP is characterized by neurological, gastrointestinal and/or cardiovascular symptoms. The main known producer of BTXs is the dinoflagellate Karenia brevis, but other microalgae are also suspected to synthesize BTX ...

Detection of Brevetoxin in Human Plasma by ELISA. [PDF]
J Anal Toxicol, 2022 Abstract Florida red tides have become more common and persistent in and around the Gulf of Mexico. When in bloom, red tides can produce brevetoxins in high concentrations, leading to human exposures primarily through contaminated food and ocean spray.

Foods, 2021 The consumption of shellfish contaminated with brevetoxins, a family of ladder-frame polyether toxins formed during blooms of the marine dinoflagellate Karenia brevis, can cause neurotoxic poisoning, leading to gastroenteritis and neurotoxic effects.

Total Synthesis of Brevetoxin-B [PDF]
Journal of the American Chemical Society, 2003 Brevetoxin-B (BTX-B), produced by the red tide organism, Gymnodium breve Davis, is the first member of marine polycyclic ethers to be structurally elucidated and one of the most potent neurotoxins. The structural feature is a trans-fused polycyclic ether ring system with 23 stereocenters.
