Title: Mode of action of calcimycin (A 23187). VI. Complexation of transition and heavy metal divalent cations in methanol
Abstract: Interaction between calcimycin HA and transition and heavy metal divalent cations M2+ in methanol was studied using potentiometry. Both MA+ and MA2 complexes are formed, except for Pb2+. The corresponding stability constants were obtained; these were high. Formation of further species involving the methanolate anion in the coordination of the metal cation is scarse. The selectivity of calcimycin anion for the various divalent cations is determined by the selectivity of its carboxylate group.
