Methods for treatment of a pathological condition caused by oxidative stress in a patient comprise administering to the patient a mixed metal complex of a compound of Formula I, or a salt thereof, in an amount effective to reduce the oxidative stress. Pharmaceutical compositions are formed by suspending or dissolving a mixed metal complex of a compound of Formula I, or a salt thereof, in a liquid medium, optionally with one or more physiologically acceptable excipients. The mixed metals comprise calcium and manganese in a molar ratio of calcium to manganese in the range of 1-10: wherein X, R, R, R, and Rare as defined herein.

Calmangafodipir, a new chemical entity, and other mixed metal complexes, methods of preparation, compositions, and methods of treatment

Methods for treatment of a pathological condition caused by oxidative stress in a patient comprise administering to the patient a mixed metal complex of a compound of Formula I, or a salt thereof, in an amount effective to reduce the oxidative stress. The mixed metals comprise calcium and manganese in a molar ratio of calcium to manganese in the range of 1-10: wherein X, R, R, R, and Rare as defined herein.

A mixed metal complex of a compound of Formula I, or a salt thereof, wherein the mixed metals comprise a Group III-XII transition metal and a Group II metal: wherein X, R, R, R, and Rare as defined herein, is produced in a one step crystallization from a solution of the Group III-XII transition metal, the Group II metal, and a compound of Formula I. Methods for treatment of a pathological condition in a patient, for example, a pathological condition caused by the presence of oxygen-derived free radicals, comprise administering the mixed metal complex to the patient.

Pharmaceutical compositions comprise a first compound of Formula I or a physiologically acceptable salt thereof, and a cyto-protective amount of a manganese chelate of N,N'-dipyridoxyl ethylenediamine-N,N&#x2032;-diacetic acid (MnPLED): wherein R, R, R, Rand X are defined in the specification.
