Grazer‐induced toxin production is energetically costly and significantly reduces growth of cylindrospermopsin‐producing cyanobacteria

Limnology and Oceanography
Toxins have been proposed as a defense mechanism for phytoplankton against zooplankton grazing. However, the associated costs are not understood.

Genotoxicity investigation of a cyanobacterial toxin, cylindrospermopsin

Toxicon, 2002
Cylindrospermopsin (CYN), a potent cyanobacterial hepatotoxin produced by Cylindrospermopsis raciborskii and other cyanobacteria, is regularly found in water supplies in many parts of the world, and has been associated with the intoxication of humans and livestock.

Photonic Aptasensor Based on the Smart Cholesteric Liquid Crystal Network Structure for Cylindrospermopsin Detection.

Analytical Chemistry
Solid-state cholesteric liquid crystals (CLCsolid) with one-dimensional photonic structure offer a promising platform for constructing chemical and biological optical sensors, owing to their facile fabrication, signal readout, and sensitive and selective

Interlaboratory comparison trial on cylindrospermopsin measurement

Analytical Biochemistry, 2004
The hepatotoxin cylindrospermopsin (CYN) is a potent inhibitor of protein synthesis in mammalian cells. It is produced by freshwater cyanobacterial blooms in countries such as Australia, the United States, Israel, Thailand, and Brazil. An interlaboratory comparison was organized as a first step to evaluate the measurement of CYN in lyophilized ...

Biosynthesis of Cylindrospermopsin in Cyanobacteria: Characterization of CyrJ the Sulfotransferase

Journal of Natural Products, 2021
7-Deoxy-desulfo-cylindrospermopsin was purified at small-scale from the supernatant of a culture of the cyanobacterium Oscillatoria sp. PCC 10702. This metabolite was obtained in a pure form using a three-step chromatographic procedure, and its identity was confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Isolation and identification of the cyanotoxin cylindrospermopsin and deoxy-cylindrospermopsin from a Thailand strain of Cylindrospermopsis raciborskii (Cyanobacteria)

Toxicon, 2001
A strain of Cylindrospermopsis (Cyanobacteria) isolated from a fishpond in Thailand was examined for its taxonomy based upon morphology and 16S rRNA gene sequence. It was also examined for production of the hepatotoxic cyanotoxin called cylindrospermopsin (CYN) and deoxycylindrospermopsin (deoxy-CYN).

Report of the cyanotoxins cylindrospermopsin and deoxy-cylindrospermopsin from Raphidiopsis mediterranea Skuja (Cyanobacteria/Nostocales)

Harmful Algae, 2011
Abstract A filamentous cyanobacterium isolated from the plankton of a eutrophic reservoir in Queensland (Australia) was, based on morphological features, putatively identified as Raphidiopsis mediterranea Skuja. Strain FSS1-150/1 was screened by HPLC MS/MS for a number of common cyanotoxins and was shown to produce both cylindrospermopsin (CYN) and ...

Synthetic Studies on a Model of Cylindrospermopsin

Synlett, 2007
A new strategy for the synthesis of cylindrospermopsin is described using an intramolecular Mannich reaction to form ring A. Guanylation of the piperidine nitrogen and reaction on an activated double bond generates ring B.
