Enniatins are a family of depsipeptides produced several Fusarium species. The enniatins have been shown to act as ionophores. More recently their effects on acyl-CoA cholesterol transferase, transporters and the selectivity of their antitumor action have received more focus. Enniatin B1 is one of four major analogues of the enniatin complex and has not previously been available for investigation. Source: Enniatin B1 Molecular Weight: ~653.9 Solubility: Soluble in ethanol, methanol, DMF or DMSO. Storage and Stability: Lyophilized powder may be stored at -20 degrees C.
