| Abstract: | The ion-transporting antibiotic beauvericin has been shown to have a high affinity for calcium and barium ions in addition to the more usual affinity for monovalent cations. As judged by crystallization, extraction into organic solvent, and U-tube transport the cation selectivity is Rb>Ba>K>Na?Ca?Li. For these studies an improved method for the synthesis of beauvericin has been developed. |
