Biodegradative and biosynthetic capacities of mushrooms: present and future strategies
TL;DR: In this paper, the authors present and future strategies for the development of biodegradative and biosynthetic Capacities of Mushrooms, and discuss the current state of the art.
Journal ArticleDOI
First electron spin resonance evidence for the production of semiquinone and oxygen free radicals from orellanine, a mushroom nephrotoxin
TL;DR: The formation of an apparently stable ortho-semiquinone anion radical and of reactive oxygen radical species is observed for the first time with a mushroom toxin and may at least partly explain the toxicity of orellanine.

Chromatographic behaviour and determination of orellanine, a toxin from the mushroom Cortinarius orellanus.

Poisoning by members of the genus Cortinarius - a review.
D. Michelot,I. Tebbett +1 more
TL;DR: Current knowledge of the poisonings, the toxins incriminated and their mechanism of action are reviewed; the toxins in question are presumably orellanine and cortinarins.
Journal ArticleDOI
Peroxidase-Mediated Oxidation, a Possible Pathway for Activation of the Fungal Nephrotoxin Orellanine and Related Compounds. ESR and Spin-Trapping Studies
TL;DR: None of the orellanine-related compounds can be oxidized by the HRP/H2O2 system, showing that both catecholic moieties and aminoxide groups are necessary for observing the formation of the ortho-semiquinone form of orelanine.

Mode of action of dipyridyl quaternary salts as herbicides.
TL;DR: In this article, a specific type of herbicidal activity is shown by certain diquaternary salts of 2,2′-, 2,4′- and 4, 4′-dipyridyl.

Mushroom poisoning caused by species of the genus Cortinarius Fries.

TL;DR: Pharmacokinetic experiments on the nephrotoxic bipyridines suggest that haemoperfusion is a rational therapy of intoxicated persons, even several days after mushroom ingestion, which is comparable to orellanine toxicity.
