Production of enniatin A

Canadian Journal of Microbiology, 1973
Growth of a strain of Fusarium sambucinum in surface culture on a specially developed medium gave high yields of enniatins, from which enniatin A, free from the B and C homologues, could be obtained by column chromatography in yields of 1 g or more per liter of culture.

Biosynthesis and biological activity of enniatins

Die Pharmazie, 2007
Enniatins are N-methylated cyclohexadepsipeptides (CHDPs), composed of three units each of N-methylated branched-chain L-amino acid and L-2-hydroxy acid arranged in an alternate fashion. These low-molecular secondary metabolites are produced by Fusarium species, typical mycotoxin producing fungi. Enniatins are known for their ionophoric, phytotoxic and

The structure of enniatins and related antibiotics

Tetrahedron, 1963
Abstract The synthesis of cyclotetradepsipeptides the structure of which has previously been assigned to antibiotics of the enniatin group is described. It was found that these antibiotics cannot be represented by the formulas (I)–(VI).

Enniatin A1, enniatin B1 and beauvericin on HepG2: Evaluation of toxic effects

Food and Chemical Toxicology, 2015
Hepatotoxicity of three Fusarium mycotoxins, beauvericin (BEA) and two enniatins (ENNs) ENN A1 and ENN B1, in hepatocarcinoma cells (HepG2) were evaluated and compared. Concentrations used were 1.5 and 3 μM at 24, 48 and 72 h for each mycotoxin. Flow cytometry was used to examine enniatins effects on cell proliferation, to characterize the cell cycle ...

Investigation of the electrophysiological properties of enniatins

Archives of Biochemistry and Biophysics, 2004
Enniatins are cyclohexadepsipeptides produced by various species of the genus Fusarium, and are known to have ionophoric, antibiotic, and in vitro hypolipidaemic properties. With the patch clamp technique in the inside-out mode it could be shown that enniatin easily incorporates into the cell membrane in which it forms cation-selective pores.

Stimulation of erythrocyte phospholipid scrambling by enniatin A

Molecular Nutrition and 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.

Synthesis of enniatin B

Experientia, 1963
Die Struktur von Enniatin B, eines antimikrobiellen Wirkstoffes aus Fusarienstammen (ETH, Zurich), wird durch Synthese als die eines Cyclohexapeptolids bewiesen (vgl. X).

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.
