Comparative Oral Bioavailability, Toxicokinetics, and Biotransformation of Enniatin B1 and Enniatin B in Broiler Chickens

Journal of Agricultural and Food Chemistry, 2016
A toxicokinetic study of the Fusarium mycotoxins enniatin B1 (ENN B1) and enniatin B (ENN B) was performed in broiler chickens. Each animal received ENN B1 or B orally via an intracrop bolus and intravenously at a dose of 0.2 mg/kg body weight. Both enniatins were poorly absorbed after oral administration, with absolute oral bioavailabilities of 0.05 ...

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.

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.

Study of locomotion response and development in zebrafish (Danio rerio) embryos and larvae exposed to enniatin A, enniatin B, and beauvericin

Science of The Total Environment, 2021
Mycotoxins are secondary metabolites produced by a variety of fungi that contaminate food and feed resources, and are capable of inducing a wide range of toxicity. Here, we studied the developmental and behavioral toxicity in zebrafish (Danio rerio) embryos and larvae exposed to three mycotoxins: beauvericin (BEA), Enniatin A (ENN A), and Ennitain B ...

The Crystal Structure of Enniatin B

Helvetica Chimica Acta, 1985
AbstractThe X‐ray crystal structure of enniatin B (trigonal (hexagonal axes), a = 14.626 Å, c = 16.309 Å, space group R3) is described and the conformation compared to results of other investigations.

A molecular orbital study on the conformation of enniatin B

Biochemical and Biophysical Research Communications, 1973
Abstract Molecular orbital calculations using the PCILO method are performed on the conformation of the symmetrical form of enniatin B. The values of the Φ and ψ angles found for the preferred conformation agree closely with the results of X-ray study of the K + complex of enniatin B.

Mechanism of depsipeptide formation catalyzed by enniatin synthetase

Biochemical and Biophysical Research Communications, 1983
Covalently bound intermediates of enniatin B synthesis could be isolated from enniatin synthetase by treatment with performic acid. By comparison with products of mild alkaline cleavage of authentic enniatin B they could be identified as the dipeptide D-2-hydroxyisovaleryl-N-methylvaline and the corresponding tetrapeptide.

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

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

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.
