产品描述：
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.
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].
Clinical trial: Up to now, enniatin B is still in the preclinical development stage.
