Beauvericin and enniatin: emerging toxins and/or remedies?

World Mycotoxin Journal, 2010
Beauvericin (BEA) and enniatins (ENN) are emerging Fusarium mycotoxins that are known to contaminate food and feed. BEA- and ENN-mediated cytotoxicity towards various mammalian and cancer cell lines is only partly understood yet and engages several cellular targets and molecular mechanisms.

THE ENNIATIN IONOPHORES. CONFORMATION AND ION BINDING PROPERTIES

International Journal of Peptide and Protein Research, 1974
The ability of enniatins to bind alkali metal, alkaline earth metal and certain transition metal ions in solution has been investigated. The complexes have been shown to form in 1:1, 2:1 and 3:2 macrocycle:cation ratios; their stability constants have been determined, and the conditions favoring their formation have been established. The enniatins were

Stimulation of erythrocyte phospholipid scrambling by enniatin A

Molecular Nutrition & Food Research, 2011
AbstractScope: Enniatin A, a peptide antibiotic and common food contaminant, triggers mitochondrial dysfunction and apoptosis. Even though lacking mitochondria, erythrocytes may similarly undergo suicidal cell death or eryptosis. Eryptosis is characterized by cell shrinkage and cell membrane phospholipid scrambling.

Conformation of enniatine B in nonpolar solvents

Chemistry of Natural Compounds, 1974
1. The relative positions of the CαH and N-Ch3 signals in the1H NMR spectra of different conformers of enniatine B have been evaluated. 2. The1H NMR spectra [tri-(N-methyl-D-valyl-Cα-d)] enniatine B have been investigated. 3. The spatial structure of enniatine B in nonpolar media has been determined.

Fusaproliferin, beauvericin and enniatins: occurrence in food – a review

World Mycotoxin Journal, 2012
The present review summarises data on the prevalence and concentration of fusaproliferin, beauvericin and enniatins in small grains, maize and processed grain-based foods. These fungal secondary metabolites possess interesting biological activities and are presently often referred to as 'emerging mycotoxins'. They have been considered as less important

Involvement of enniatins-induced cytotoxicity in human HepG2 cells

Toxicology Letters, 2013
Enniatins (ENNs) are mycotoxins found in Fusarium fungi and they appear in nature as mixtures of cyclic depsipeptides. The ability to form ionophores in the cell membrane is related to their cytotoxicity. Changes in ion distribution between inner and outer phases of the mitochondria affect to their metabolism, proton gradient, and chemiosmotic coupling,

Theoretical conformational analysis of cyclic hexadepsipeptides. Enniatins

Chemistry of Natural Compounds, 1970
The spatial conformation of the “polar” form of enniatin B has been established. A conformation of the N1 type has been proposed for the “nonpolar” form.

Effects of technological processes on enniatin levels in pasta

Journal of the Science of Food and Agriculture, 2015
AbstractBACKGROUNDPotential human health risks posed by enniatins (ENs) require their control primarily from cereal products, creating a demand for harvesting, food processing and storage techniques capable to prevent, reduce and/or eliminate the contamination.
