Enniatins A1, B and B1 from an endophytic strain of Fusarium tricinctum induce apoptotic cell death in H4IIE hepatoma cells accompanied by inhibition of ERK phosphorylation

Molecular Nutrition and Food Research, 2009
Enniatins are mycotoxins which have important impact on human health, e.g. as contaminants of cereals, but also are discussed as possible anticancer agents.

Evaluation of enniatins A, A1, B, B1 and beauvericin in Portuguese cereal-based foods

Food Additives and Contaminants - Part A Chemistry, Analysis, Control, Exposure and Risk Assessment, 2012
Sixty-one samples of Portuguese cereal-based foods were analysed for the occurrence of emerging mycotoxins called enniatins (A, A1, B and B1) and beauvericin.

Development of a LC-MS/MS Method for the Analysis of Enniatins and Beauvericin in Whole Fresh and Ensiled Maize

Journal of Agricultural and Food Chemistry, 2008
A LC-MS/MS method for the detection of beauvericin and the four enniatins A, A1, B, and B1 in maize and maize silage was developed. The method uses direct injection of maize extracts without any tedious and laborious cleanup procedures.

Investigating the Efficiency of Hydroxycinnamic Acids to Inhibit the Production of Enniatins by Fusarium avenaceum and Modulate the Expression of Enniatins Biosynthetic Genes [PDF]

Toxins, 2020
Enniatins (ENNs) that belong to the group of emerging mycotoxins are widespread contaminants of agricultural commodities. There is currently insufficient evidence to rule out health concerns associated with long-term exposure to ENNs and efforts must be strengthened to define a control strategy.

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.

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 ...

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).

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.
