Development of a validated direct injection-liquid chromatographic tandem mass spectrometric method under negative electrospray ionization for quantitation of nine microcystins and nodularin-R in lake water

Journal of Chromatography A, 2020
Microcystins (MCs) are cyclic heptapeptide toxins produced by various cyanobacterial genera that are toxic to both animals and humans. In this study, a novel strategy was proposed for the quantitation of nine MCs and Nodularin-R (NOD) in lake water using UHPLC-MS/MS under negative ionization mode, in which only centrifugation was employed during sample

Theoretical investigation of microcystin-LR, microcystin-RR and nodularin-R complexation with α-, β-, and γ-cyclodextrin as a starting point for the targeted design of efficient cyanotoxin traps

Sustainable Chemistry and Pharmacy, 2016
Abstract The interactions of three abundant cyanotoxins, namely microcystin-LR, microcystin-RR and nodularin-R with α-, β-, and γ-cyclodextrin in water were structurally and thermodynamically investigated by a computationally affordable methodology using the semi-empirical PM7 method in conjunction with an implicit treatment of solvent effects by the

A Visible-Light-Driven Self-Powered Nodularin-R Biosensing Platform Controlled by an Integrated Portable Photoelectrochemical Detection Device

Analytical Chemistry
The presence of nodularin-R (NOD-R) in water has gained considerable attention because of its widespread distribution and high toxicity. In this study, an accurate and rapid visible-light-driven self-powered photoelectrochemical (PEC) biosensor was developed by integrating a portable paper-based electrode with a custom-built miniaturized PEC detection ...

Determination of oxidation rate constant for nodularin‐r, saxitoxin, dc‐saxitoxin, and neo‐saxitoxin with conventional water treatment plant oxidants and advanced oxidation processes

AWWA Water Science
AbstractThe effectiveness of chemical oxidation depends on the type of cyanotoxins present in the water and varies with the water quality parameters. This study investigated four cyanotoxins to understand their reactions with conventional drinking water treatment plant oxidants and with advanced oxidation.

Drug Designing and Molecular Dynamics Identifies Cyanobacterial Nodularin-R as the Candidate Molecule Against SARS‒CoV‒2 Main Protease (Mpro)

Journal of Environmental Science and Agricultural Research
The COVID-19 pandemic, caused by SARS-CoV-2, is a significant public health challenge. One approach to combat this virus is to develop antiviral drugs from natural products, such as those produced by cyanobacteria. Cyanobacteria produce a diverse range of secondary metabolites (SMs), including nodularin, aplysiatoxin, and obyanamide, which have unique ...
