Detection of nodularin in European flounder (Platichthys flesus) in the west coast of Sweden: Evidence of nodularin mediated oxidative stress [PDF]
Harmful Algae, 2009 The brackish, bloom-forming cyanobacterium Nodularia spumigena produces a peptide called nodularin, which may induce liver damage in fish.

The photocatalytic destruction of the cyanotoxin, nodularin using TiO2 [PDF]
Applied Catalysis B: Environmental, 2005 Abstract Titanium dioxide (TiO 2 ) photocatalysis has been used to initiate the destruction of nodularin, a natural hepatotoxin produced by cyanobacteria. The destruction process was monitored using liquid chromatography–mass spectrometry analysis which has also enabled the identification of a number of the photocatalytic decomposition products.

Cloud-point extraction of nodularin-R from natural waters [PDF]
Analytica Chimica Acta, 2004 A cloud-point extraction (CPE) technique for the determination of a cyanobacterial hepatotoxin, nodularin-R, in aqueous media using a cationic surfactant, tricaprylmethylammonium chloride (Aliquat-336), was developed.

Biodegradation of microcystins and nodularin in freshwaters
Chemosphere, 2008Microcystin-LR (MC-LR) was readily biodegraded on addition to six different water samples irrespective of their previous exposure to microcystins. Subsequent studies with water from three of these water bodies confirmed the degradation of MC-LR and also demonstrated the biodegradation of MC-LF, nodularin and mixture of microcystins and nodularin.

Nodularin, a cyanobacterial toxin, is synthesized in planta by symbiotic Nostoc sp. [PDF]
ISME Journal, 2012 The nitrogen-fixing bacterium, Nostoc, is a commonly occurring cyanobacterium often found in symbiotic associations. We investigated the potential of cycad cyanobacterial endosymbionts to synthesize microcystin/nodularin.

Suppression of IL-2 and IL-4 gene expression by nodularin through the reduced NF-AT binding activity [PDF]
Toxicology Letters, 2000 Nodularin is a cyclic peptide produced by cyanobacteria. In the present study, the inhibitory effect of nodularin on T lymphocyte functions was demonstrated.

Comprehensive insights into the occurrence and toxicological issues of nodularins
Marine Pollution Bulletin, 2021The occurrence of cyanobacterial toxins is being increasingly reported. Nodularins (NODs) are one of the cyanotoxins group mainly produced by Nodularia spumigena throughout the world. NODs may exert adverse effects on animal and human health, and NOD-R variant is the most widely investigated. However, research focused on them is still limited. In order

Clinica Chimica Acta, 2013
Nodularins are an important class of hepatotoxic cyclic pentapeptides that are produced by the cyanobacteria Nodularia spumigena. These peptides have been found worldwide and have been implicated in the deaths of animals as well as a potent cyanotoxin in humans.

Nodularin-Har: A New Nodularin from Nodularia
Journal of Natural Products, 2000A cyanobacterial hepatotoxin, nodularin-Har, having a homoarginine instead of an arginine in nodularin, was isolated from Nodularia PCC7804. The structure was elucidated as 1 on the basis of 2D NMR and FABMS. The LD(50) (mouse ip) value of 1 was 70 microg/kg.

Redox Mechanisms of Nodularin and Chemically Degraded Nodularin
Electroanalysis, 2011AbstractThe electrochemical behaviour of Nodularin (NOD), a hepatotoxic cyclic pentapeptide, was studied at a glassy carbon electrode. NOD electrochemical oxidation is an irreversible, pH‐independent process, involving the transfer of one electron. Upon incubation in different pH electrolytes, chemical degradation of NOD was electrochemically detected ...
