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 ...

A total synthesis of the ammonium ionophore, (−)-enniatin B

Tetrahedron Letters, 2012
Abstract A nine-step (longest linear) batch total synthesis of the cyclic hexadepsipeptide (−)-enniatin B is described. The synthesis minimizes precipitation during reaction conditions for adaptability to flow synthesis. The route was used to prepare >100 mg of the natural product.

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.

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).

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.

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.

In vitro phase I metabolism of the depsipeptide enniatin B

Analytical and Bioanalytical Chemistry, 2011
The enniatins are a group of more than 20 cyclic depsipeptides from fungi with numerous biological effects. Enniatin B is commonly one of the principal analogues in species of the genus Fusarium, known to have ionophoric, antibiotic and insecticidal activity. In the present study, enniatin B was incubated with rat, dog and human liver microsomes.
