    • A method for administering pyruvate is disclosed which comprises administering a therapeutically effective amount of a pyruvate precursor to a mammal in the form of pyruvamide or a pyruvyl-amino acid. The pyruvyl-amino acid is preferably selected from the group comprising pyruvyl-glycine, pyruvyl-alanine, pyruvyl-leucine, pyruvyl-valine, pyruvyl-isoleucine, pyruvyl-phenylalanine, pyruvyl-proline and pyruvyl-sarcosine, and their amides and esters as well as their salts. Associated with the administration of a pyruvate precursor to a mammal in accordance with this invention are improved insulin resistance, lower fasting insulin levels, and reduced fat gain. Novel methods of synthesizing several pyruvate precursors are also disclosed.
    • 公开了一种给予丙酮酸盐的方法,其包括给予哺乳动物治疗有效量的丙酮酸前体以丙酮酰胺或丙酮酸 - 氨基酸的形式。 丙酮酸氨基酸优选选自丙酮酸 - 甘氨酸,丙酮酸 - 丙氨酸,丙酮酸 - 亮氨酸,丙酮酸 - 缬氨酸,丙酮酸 - 异亮氨酸,丙酮酸 - 苯丙氨酸,丙酮酸 - 脯氨酸和丙酮酸 - 肌氨酸,其酰胺和酯为 以及它们的盐。 与根据本发明的哺乳动物的丙酮酸前体的施用相关联的是改善的胰岛素抵抗,降低的空腹胰岛素水平和降低的脂肪增加。 还公开了合成若干丙酮酸前体的新方法。
