Tissue Distribution and Metabolization of Ciguatoxins in an Herbivorous Fish following Experimental Dietary Exposure to Gambierdiscus polynesiensis [PDF]
Marine Drugs, 2023 Ciguatoxins (CTXs), potent neurotoxins produced by dinoflagellates of the genera Gambierdiscus and Fukuyoa, accumulate in commonly consumed fish species, causing human ciguatera poisoning.

Sensitive Detection of Ciguatoxins Using a Neuroblastoma Cell-Based Assay with Voltage-Gated Potassium Channel Inhibitors [PDF]
ToxinsCiguatoxins (CTXs) are neurotoxins responsible for ciguatera poisoning (CP), which affects more than 50,000 people worldwide annually. The development of analytical methods to prevent CP is a pressing global issue, and the N2a assay is one of the most ...

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
