A Multistep Oxidative Cascade Reaction from a Naphthalenediol‐Based Pre‐Ligand to a Tetranuclear Perylenequinone‐Based FeIII Complex

Chemistry – A European Journal, Volume 31, Issue 6, January 27, 2025.
Two 1,8‐naphthalenediol‐based ligands are coupled in a multistep oxidative cascade reaction to a tetranuclear perylenequinone‐based FeIII complex involving an overall 10‐electron oxidation. The assignment of the electronic structure of the new backbone is based on experimental data supported by DFT calculations.

Diversity of Alternaria‐derived toxins and their toxicodynamic and toxicokinetic characteristics in the food chain

Food Frontiers, Volume 6, Issue 1, Page 185-217, January 2025.
The Alternaria genus includes over 250 fungal species that contaminate crops and food with harmful mycotoxins, posing risks to plant, animal, and human health. This review discusses the classification, impact, and prevalence of Alternaria mycotoxins, their toxicodynamics and toxicokinetics, and highlights the need for regulations and preventive ...

Elsinoe species: The rise of scab diseases

Plant Pathology, Volume 74, Issue 1, Page 39-58, January 2025.
We critically evaluate research on the taxonomic status, phylogenetic relationships, host range, biology and epidemiology of Elsinoe causing scab diseases—a genus known for over 100 years but which remains poorly understood. Abstract The genus Elsinoe contains many aggressive pathogens of a wide range of plants, many of which are economically important.

Antimicrobial Polymeric Nanoparticles in Endodontics: A Systematic Review

Journal of Nanotechnology, Volume 2025, Issue 1, 2025.
Background: The efficacy of endodontic treatments, essential for managing infections and injuries in dental pulp, heavily relies on completely eradicating microorganisms from the root canal system. Traditional methods often fail to achieve thorough disinfection, prompting the exploration of polymeric nanoparticles for their potential to enhance ...

Phaeosphaerins A–F, Cytotoxic Perylenequinones from an Endolichenic Fungus, Phaeosphaeria sp.

, 2016
Six novel phototoxins, phaeosphaerins A–F (1–6), together with six known perylenequinones were isolated from an endolichenic fungus Phaeosphaeria sp. Their structures were determined unequivocally on the basis of comprehensive analysis of MS and NMR data

Mini‐review of developments in the chemical modification of plant‐derived photosensitizing drug hypocrellin and its biomedical applications

Interdisciplinary Medicine, Volume 2, Issue 4, October 2024.
This review focuses exclusively on a plant‐derived photosensitizing drug‐hypocrellin for its chemical modification and its significant potential in biomedical applications. Hypocrellin is an ideal candidate due to its straightforward preparation and purification processes, high phototoxicity, low toxicity in the absence of light, and rapid metabolism ...

Significance of lignin and fungal markers in the Devonian (407 Ma) Rhynie Chert

Geobiology, Volume 22, Issue 4, July/August 2024.
Abstract The Rhynie Chert (Lower Devonian, Scotland) hosts a remarkably well‐preserved early terrestrial ecosystem. Organisms including plants, fungi, arthropods, and bacteria were rapidly silicified due to inundation by silica‐rich hot spring fluids.
