ENNIATIN B Chemical Properties,Uses,Production
Uses
Enniatins are a family of depsipeptide ionophores produced by several Fusarium species. Recently, the effects of the enniatins on acyl-CoA cholesterol transferase, transporters and the selectivity of their antitumor action have received more focus. Enniatin B is the most studied of four major analogues of the enniatin complex.

Definition
ChEBI: An enniatin obtained from formal cyclocondensation of three N-[(2R)-2-hydroxy-3-methylbutanoyl]-N-methyl-L-valine units.
Biological Activity
enniatin b is an ionophore antibiotic.enniatins are one of the cyclohexadepsipeptides produced by various species of the genus fusarium, and are reported to have antibiotic, ionophoric, and in-vitro hypolipidaemic activities.
Biochem/physiol Actions
Enniatins are a group of cyclohexadepsipeptide mycotoxins produced by Gnomonia errabuda and several Fusaria species, with phytotoxic, antibiotic, and insecticidal activities. Enniatins function as ionophors by their incorporation into the cellular membrane to form dimeric structures that transport monovalent ions across the membrane (especially the mitochondrial membranes) affecting oxidative phosphorylation uncoupling. It has been demonstrated that enniatins have a cytotoxic effect on human cancer cells. Furthermore, incubation of H4IIE hepatoma cells with enniatins strongly diminished phosphorylation of the ERK (p44/p42). Enniatins B and B1 inhibit the multi-drug resistance transporter Pdr5p from Saccharomyces cerevisiae, indicating their beneficial potential in cases of drug resistant patients.
in vitro
a non-toxic concentration of enniatin b could strongly inhibit a pdr5p-mediated efflux of cycloheximide or cerulenin in pdr5p-overexpressing cells. the mode of pdr5p inhibition caused by enniatin b was competitive against fk506. however, enniatin b could not inhibit the function of snq2p, a homologue of pdr5p [1]. another study showed that enniatin b was a relatively poor ionophore that could facilitate import of k+ and na+ across membranes [2]. it was also found that like other enniatins, enniatin b was able to inhibit acyl-coa: cholesterol acyltransferase [3].
in vivo
after oral administration to mice, no toxicological signs or pathological changes were observed. moreover, enniatin b was found in all tissues and serum but not in urine, and the highest amounts was measured in liver and fat. three phase i metabolites of enniatin b were found in liver and colon, with dioxygenated-enniatin b being most prominent [4].
