Biosynthesis of ¹⁵N₃-Labeled Enniatins and Beauvericin and Their Application to Stable Isotope Dilution Assays

, 2016
The first stable isotope dilution assay for the determination of enniatins A, A1, B, and B1 and beauvericin was developed. The 15N3-labeled enniatins and beauvericin were biosynthesized by feeding two Fusarium strains Na15NO3 and subsequently isolated ...

Effects of beauvericin on phosphorylated Akt in T cells activated by Con A or anti-CD3/anti-CD28.

, 2013
(A–B) Beauvericin inhibited Akt phosphorylation in T cells stimulated with anti-CD3/anti-CD28 or Con A. Cells were harvested and whole-cell extracts were analyzed by western blot analysis.

Overview of the suppressive effects of beauvericin on activated T cells targeting Akt phosphorylation.

, 2013
Beauvericin acts against multiple aspects of activated T cells: inhibiting proliferation and activation, suppressing cytokine profiles, and inducing apoptosis. These effects are closely associated with the downregulation of Akt phosphorylation.

Extraction and DFT study on the complexation of Zn(2+) with beauvericin.

Acta chimica Slovenica, 2013
From extraction experiments and g-activity measurements, the exchange extraction constant corresponding to the equilibrium Zn2+(aq) + 1 . Sr2+(nb) 1 . Zn2+(nb) + Sr2+(aq) taking place in the two-phase water-nitrobenzene system (1 = beauvericin; aq = aqueous phase, nb = nitrobenzene phase) was evaluated as log Kex (Zn2+, 1 . Sr2+) = -0.3 ± 0.1. Further,

Cytotoxic Effects of Major and Emerging Mycotoxins on HepaRG Cells and Transcriptomic Response after Exposure of Spheroids to Enniatins B and B1

Toxins
Mycotoxins, produced by fungi, frequently occur at different stages in the food supply chain between pre- and postharvest. Globally produced cereal crops are known to be highly susceptible to contamination, thus constituting a major public health concern.
