Development of Simultaneous Analytical Method of Three Polypeptide Toxins α-Amanitin, β-Amanitin and Phalloidin in Poisonous Mushrooms and Human Serum Using UHPLC-MS/MS. [PDF]
ABSTRACT Accidental ingestion of toxic mushrooms remains a global public health concern because of the presence of highly potent peptide toxins such as α‐amanitin, β‐amanitin, and phalloidin. These compounds exhibit strong hepatotoxicity and can lead to acute liver failure and death.

Isolable Cysteine Sulfenyl Iodide: Stabilization by a Molecular Cradle, Crystal Structure, and Biologically Relevant Reactivity. [PDF]
An isolable cysteine sulfenyl iodide (Cys–SI) stabilized by a molecular cradle is reported. X‐ray analysis and reactivity studies reveal hydrolysis to sulfenic acid, electrophilic substitution with indoles, and high reactivity toward amines and dimedone, providing direct evidence for long‐standing proposals on iodine‐mediated protein modification ...

Unraveling the Carcinogenic Mechanisms of Food Contaminants: An Integrated in Silico Framework Combining Network Toxicology, Machine Learning, and Molecular Docking. [PDF]
ABSTRACT Food contamination poses a significant global health threat with carcinogenic potential, though the molecular pathways connecting contaminants to cancer remain poorly understood. This study sought to identify key molecular targets mediating the carcinogenic effects of nine prevalent dietary contaminants: glyphosate, perfluorooctane sulfonate ...

The occurrence of ansamers in the synthesis of cyclic peptides [PDF]
α-Amanitin is a bicyclic octapeptide composed of a macrolactam with a tryptathionine cross-link forming a handle. Previously, the occurrence of isomers of amanitin, termed atropisomers has been postulated.
