NMR conformational-analysis of complexes of the carboxylic ionophore nigericin with NA+ and K+

Magnetic Resonance in Chemistry 32 (2) 83-86

par Administrateur - publié le

Abstract :

The conformations of the complexes formed by the ionophore nigericin with Na+ and K+ in CDCl3 solution determined by ROESY NMR and distance geometry computations are in good agreement with the X-ray crystallographic data. The structures with the Na+ ion are more compact than those with the K+ ion, as the latter have a wider cage for the ion.
