Ergot Alkaloids Mycotoxins in Cereals and Cereal-Derived Food Products: Characteristics, Toxicity, Prevalence, and Control Strategies

Agronomy, 2021
Ergot alkaloids (EAs) are a group of mycotoxins that are mainly produced from the plant pathogen Claviceps. Claviceps purpurea is one of the most important species, being a major producer of EAs that infect more than 400 species of monocotyledonous ...

The Biological Roles of Class II Hydrophobins at the Cell Wall of Filamentous Ascomycetes

Journal of Basic Microbiology, Volume 66, Issue 10, October 2026.
ABSTRACT One of the most elusive aspects of fungal cell wall biology has been dilucidating the specific functions of most cell wall proteins. Class II hydrophobins are small amphipathic proteins produced exclusively by filamentous ascomycetes. A comparative synthesis of their biological functions across species has been lacking for this specific group ...

Antimicrobial and Antibiofilm Activity of an Endophytic Fungus, Daldinia sp. Isolated From Avicennia officinalis

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
An endophytic fungus (Daldinia sp.) was isolated from the leaves of Avicennia officinalis collected from mangrove forests of Goa. The ethyl acetate extract of Avicennia officinalis (AO‐EA) of the identified endophyte demonstrated antibacterial and antibiofilm activity against Escherichia coli and Shigella sp.

A Multi‐Target Approach to Colitis: Ergothioneine Promotes Recovery by Restoring the Intestinal Barrier, Reducing Inflammation, and Remodeling the Microbiota

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
In LPS‐induced Caco‐2 cells, EGT inhibits inflammatory cytokine overproduction and restores tight‐junction proteins. In DSS‐induced colitis mice, EGT alleviates colitis symptoms, lowers inflammatory mediators and immunoglobulins, and remodels gut microbiota.

Ergothioneine: Biosynthesis, Molecular Mechanisms, Physiological Function, and Role in Disease

MedComm, Volume 7, Issue 9, September 2026.
Ergothioneine is a natural thione antioxidant with significant biomedical potential. By reducing oxidative stress, inflammation, mitochondrial dysfunction, and cellular injury, ergothioneine may support interventions for aging‐related disorders, neurodegeneration, metabolic diseases, and skin protection.

Effect of Field-applied Fungicides on Claviceps purpurea Sclerotia and Associated Toxins in Wheat

Journal of Food Protection, 2023
Claviceps purpurea (Fr.) Tul is the causal organism for ergot impacting grass hosts, including wheat. The pathogen produces ergot alkaloids (EAs) during the development of mature sclerotia leading to potential wheat quality discounts or rejection at the ...

An Open‐Label, 2‐Period, Fixed Sequence Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of Single Doses of STS101 (Dihydroergotamine Nasal Powder), with and without Concomitant Itraconazole in Healthy Adult Subjects

The Journal of Clinical Pharmacology, Volume 66, Issue 8, August 2026.
Abstract Dihydroergotamine (DHE) prescribing information contains a boxed warning regarding the possibility of serious and/or life‐threatening peripheral ischemia with co‐administration of strong cytochrome P450 3A4 (CYP3A4) inhibitors. The effects of the strong CYP3A4 inhibitor itraconazole on the pharmacokinetics and safety of nasally administered ...

Zur Biosynthese der Peptidalkaloide von Claviceps purpurea / Biosynthesis of Peptide Alkaloids of Claviceps purpurea

Zeitschrift für Naturforschung B, 1970
Using a strain of Claviceps purpurea which produces under submerged conditions chanoclavine, ergometrine and mainly ergotoxine the biosynthesis of ergoline derivatives has been studied. DL-Tryptophan- (ring-2-14C) is specifically incorporated into the lysergic acid moiety of ergotoxine· alkaloids.
