Identification of Decrease in TRiC Proteins as Novel Targets of Alpha-Amanitin-Derived Hepatotoxicity by Comparative Proteomic Analysis In Vitro

Toxins, 2021
Alpha-amanitin (α-AMA) is a cyclic peptide and one of the most lethal mushroom amatoxins found in Amanita phalloides. α-AMA is known to cause hepatotoxicity through RNA polymerase II inhibition, which acts in RNA and DNA translocation. To investigate the

Demystifying fungal systematics: A gateway to fungal literacy and societal/ecological relevance through familiar species

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 499-515, March 2026.
Fungal systematics can feel overwhelming given the vast species diversity within this kingdom, with numerous subgroups at every taxonomic rank. This often creates a disconnect between the undertsnidng of fungal taxonomic diversity and their societal relevance.

Exploring the Substitution of the C21‐OAc Moiety in [11]Cytochalasans: Synthesis and Evaluation of Fluorophore Conjugates

ChemBioChem, Volume 27, Issue 1, January 2026.
Via in silico docking of pyrichalasin H on G‐ and F‐actin, the C21‐OAc moiety is identified as a modifiable site tolerated for actin binding. Fluorescent [11]cytochalasan probes from pyrichalasin H and epoxycytochalasin C are obtained by selective C21‐OAc hydrolysis and acylation.

Multicomponent Synthesis of Fluorine‐Containing Bioactive Compounds and Drugs

European Journal of Organic Chemistry, Volume 28, Issue 38, October 15, 2025.
Multicomponent reactions are robust synthetic tools to assamble complex polyheterocycles and other interesting molecular architectures with potential application in medicinal chemistry, including their fluorine‐containing analogues. Fluorine atoms placed strategically into bioactive molecules often enhance essential pharmacokinetic parameters like ...

A New Conjugation Method Used for the Development of an Immunoassay for the Detection of Amanitin, a Deadly Mushroom Toxin

Toxins, 2018
One of the deadliest mushrooms is the death cap mushroom, Amanita phalloides. The most toxic constituent is α-amanitin, a bicyclic octapeptide, which damages the liver and kidneys.

Molecular mechanisms of hotspot variants in cytoskeletal β‐actin associated with Baraitser–Winter syndrome

The FEBS Journal, Volume 292, Issue 18, Page 4898-4917, September 2025.
Variants at position R196 in cytoskeletal β‐actin are the most common variants associated with Baraitser–Winter cerebrofrontofacial syndrome and result in craniofacial anomalies and neurodevelopmental disorders, most likely due to neuronal migration defects. This study explores the molecular mechanisms of p.R196 variants using purified proteins.

[Poisonings with Amanita phalloides].

Medycyna pracy, 2010
Amanita phalloides is the most dangerous, poisonous mushroom species in our climatic conditions. It is the cause of 90-95% of all deaths due to mushroom poisoning, a-Amanitin, a polymerase RNA II inhibitor, is mainly responsible for the Amanita phalloides toxic property.

Unraveling Hematotoxicity of α-Amanitin in Cultured Hematopoietic Cells

Toxins
Amanita phalloides poisonings account for the majority of fatal mushroom poisonings. Recently, we identified hematotoxicity as a relevant aspect of Amanita poisonings. In this study, we investigated the effects of the main toxins of Amanita phalloides, α-
