Biosynthetic Pathways of Ergot Alkaloids [PDF]

open access: yesToxins, 2014
Ergot alkaloids are nitrogen-containing natural products belonging to indole alkaloids. The best known producers are fungi of the phylum Ascomycota, e.g., Claviceps, Epichloë, Penicillium and Aspergillus species.

Ergot Alkaloids Produced by Endophytic Fungi of the Genus Epichloë

open access: yesToxins, 2015
The development of fungal endophytes of the genus Epichloë in grasses results in the production of different groups of alkaloids, whose mechanism and biological spectrum of toxicity can differ considerably.

Monitoring and Managing of Ergot Alkaloids in Cereal Grains: A Comprehensive Analysis of Analytical Challenges, Sampling Uncertainty, and Processing for Food Safety. [PDF]

open access: yesCompr Rev Food Sci Food Saf
ABSTRACT Ergot alkaloids (EAs), toxic secondary metabolites produced by Claviceps purpurea, pose food and feed safety concerns for cereal grains, particularly rye and wheat. While EAs are most frequently associated with rye, their occurrence in other cereals has been increasingly reported across diverse regions.

Methods of Lysergic Acid Synthesis—The Key Ergot Alkaloid

open access: yesMolecules, 2022
Ergot is the spore form of the fungus Claviceps purpurea. Ergot alkaloids are indole compounds that are biosynthetically derived from L-tryptophan and represent the largest group of fungal nitrogen metabolites found in nature.

The New Ergot Alkaloid [PDF]

open access: yesNature, 1936
DURING the first half of the year 1935 communications appeared from four different laboratories, in three different countries, each describing the discovery and isolation of a new alkaloid from ergot, very different in its properties from those previously known.

Vasoactive Effects of Acute Ergot Exposure in Sheep

open access: yesToxins, 2021
Ergotism is a common and increasing problem in Saskatchewan’s livestock. Chronic exposure to low concentrations of ergot alkaloids is known to cause severe arterial vasoconstriction and gangrene through the activation of adrenergic and serotonergic ...
