Abstract
A therapeutic composition comprising an alkyl, aralkyl, alkoxyalkyl or carboxyalkyl ester of 2ketoalkanoic acid and a component for inducing and stabilizing the enol resonance form of the ester at physiological pH values is disclosed. The composition of the invention further comprises a pharmaceutically acceptable carier vehicle in which the enol resonance form of the ester is stabilized at physiological pH values. Formulations containing the compositions of the invention permit the successful use of 2-ketoalkanoic acid esters, e.g., pyruvic acid esters, to treat, e.g., is chemic events, shock, organ reanimation, resuscitation and other recognized pyruvate-effective treatments. The compositions of the inventions are also useful in a process for preserving organ parts, organs or limbs removed from a living mammal and in need of preservation, e.g., for later transplantation to an organ recipient.
