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.
本发明公开了一种治疗组合物,该组合物包含 2ketoalkanoic acid 的烷基、芳基、烷氧基烷基或羧基烷基酯和一种在生理 pH 值下诱导和稳定酯的烯醇共振形式的成分。本发明的组合物还包括一种药学上可接受的carier载体,在该载体中,酯的烯醇共振形式在生理pH值下被稳定。含有本发明组合物的制剂可以成功地使用 2-酮烷酸酯,如丙酮酸酯,来治疗如化学事件、休克、器官复生、复苏和其他公认的丙酮酸有效治疗。本发明的组合物还可用于保存从活体哺乳动物身上摘除并需要保存的器官部分、器官或肢体,例如,用于以后移植给器官接受者。
