T1  - Alkali-cation specificity and carrier qualities of the antibiotics nigericin and monensin
N2  - It is shown by means of IR. spectroscopic methodsthat nigericin and monensin bave a cyclic conformation similar to that of their silver salts. Camplex fonnation constants with sodium and potassium ions follow the selectivity order determined by EMF. measurements on liquid membranes: nigericin: K\(^+\) >Rb\(^+\)> Na\(^+\)> Cs\(^+\) >Li\(^+\); monensin: Na\(^+\)> K\(^+\) >Li\(^+\)> Rb\(^+\)> Cs\(^+\). Transport experiments show that nigericin and monensin facilitate the diffusion of potassium ions across model membranes, although in electrolytic transport experiments the permeability is not affected.
