Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, Volume 44, Issue 6, Page 1013-1098, November/December 2025.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Exposure to Mycotoxin-Mixtures via Breast Milk: An Ultra-Sensitive LC-MS/MS Biomonitoring Approach

open access: yesFrontiers in Chemistry, 2020
Exposure to natural food contaminants during infancy may influence health consequences later in life. Hence, breast milk may serve as a vehicle to transport these contaminants, including mycotoxins, from mothers to their infants.

Enniatin Mycotoxins in Food: A Systematic Review of Global Occurrence, Biosynthesis, and Toxicological Impacts on In Vitro Human Cell Models

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Enniatins (ENNs) are emerging mycotoxins mainly produced by Fusarium species. They frequently contaminate cereals and cereal‐based products. Despite their widespread occurrence, these mycotoxins are not yet regulated, but concerns about their potential health effects due to dietary exposure exist.
