Antifungal effects of the bioactive compounds enniatins A, A1, B, B1

Toxicon, 2010
To produce enniatin (ENs), Fusarium tricinctum CECT 20150 was grown in a liquid medium of potato (PDB), being mycotoxin purified by high performance liquid chromatography (HPLC) with a reverse phase semipreparative column using a mobile phase of acetonitrile/water using gradient condition. The purity of the ENs fractions was verified by analytical HPLC

Effects of crystal packing and hydration on the conformation of enniatin B

Acta Crystallographica Section B Structural Science, 1987
The effects of crystal packing forces and of hydration on the conformations of the ion carrier enniatin B, cyclo-{O-CH[-CH(CH3)2]-C'O'-N(CH3)-CH[CH(CH3)2]-C'O'-}3, in two different crystal structures belonging to the trigonal space group R3 have been analyzed theoretically by the empirical forcefield method.

Interaction effects of enniatin B, deoxinivalenol and alternariol in Caco-2 cells

Toxicology Letters, 2016
Enniatin B (ENN B), deoxinivalenol (DON) and alternariol (AOH) are secondary metabolites of filamentous fungi. These mycotoxins are contaminants of vegetables and cereals. They are cytotoxic and their effects are enhanced by their mixtures. The objectives of this study were to compare the cytotoxicity of ENN B, DON and AOH alone or in combination in ...

An investigation of the endocrine disrupting potential of enniatin B using in vitro bioassays

Toxicology Letters, 2015
Evidence that some of the fungal metabolites present in food and feed may act as potential endocrine disruptors is increasing. Enniatin B (ENN B) is among the emerging Fusarium mycotoxins known to contaminate cereals. In this study, the H295R and neonatal porcine Leydig cell (LC) models, and reporter gene assays (RGAs) have been used to investigate the

Extraction and DFT study on the complexation of the strontium cation with enniatin B

Chemical Physics, 2014
Abstract By using extraction experiments and γ -activity measurements, the extraction constant corresponding to the equilibrium Sr 2+ (aq) + 2A − (aq) +  1 (nb)  ⇄ 1  · Sr 2+ (nb) + 2A − (nb) occurring in the two-phase water–nitrobenzene system (A −  = picrate, 1  = enniatin B; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as ...

Topochemical Approach in Studies of the Structure–Activity Relation: Enantio-enniatin B

Nature, 1967
THE interaction of a biologically active substance with a selective receptor (for instance, substrate and enzyme) to cause a certain physiological effect is chemically complex, requiring not only a certain minimum of steric congruity of the molecules but also a given electron density distribution in the interacting functional centres.

Production of type A trichothecenes and enniatin B byFusarium sambucinum Fuckel sensu lato

Mycopathologia, 1995
Twenty-nine Fusarium isolates, representing three new taxa originated by Nirenberg from F. sambucinum Fuckel sensu lato, namely: F. sambucinum Fuckel sensu stricto, F. venenotum Nirenb., and F. torulosum (Berk. & Curt.) Nirenb., were tested for in vitro production of toxic secondary metabolites on autoclaved corn kernels. F.

Enniatin B and Valinomycin as Ion Carriers: An Empirical Force Field Analysis

Journal of Biomolecular Structure and Dynamics, 1984
The alkali-ion binding properties of two natural depsipeptide ion carriers, enniatin B (EnB) and valinomycin (VM), are examined and compared by the empirical force field method. While VM has been shown to bind preferentially K+, Rb+, and Cs+ over Na+ in most solvents, EnB is considerably less specific.

Complexation of the potassium cation with enniatin B: an experimental and theoretical study

Monatshefte für Chemie - Chemical Monthly, 2016
Extraction experiments in the two-phase water-nitrobenzene system and γ-activity measurements were used to determine the stability constant of the enniatin B–K+ complex dissolved in nitrobenzene saturated with water as 105.5±0.2. Quantum mechanical calculations were applied to predict the most probable structure of this cationic complex species.
