    • The present invention describes compounds produced from an orotic acid molecule and an amino acid molecule. The compounds being in the form of amino acid orotate compounds bound by an amide linkage and produced by one of two disclosed methods; 1) reacting orotic acid or derivatives thereof with a thionyl halide, and then combining the acyl halide with an amino acid in the presence of dichloromethane and a DMAP catalyst; or 2) protecting the carboxylic acid of an amino acid and then combining the amino acid with a DCC activated orotic acid, followed by removal of the carboxylic acid protecting group. The resulting amino acid orotate amide has an enhanced stability in solution as compared to a related ester. In addition, specific benefits are conferred by the particular amino acid used to form the compounds in addition to, and separate from, the orotate substituent.
    • 本发明描述了由乳清酸分子和氨基酸分子产生的化合物。 化合物是由酰胺键结合的氨基酸乳清酸酯化合物的形式,并通过两种公开的方法之一产生; 1)将乳清酸或其衍生物与亚硫酰卤反应,然后在二氯甲烷和DMAP催化剂的存在下将酰基卤与氨基酸组合; 或2)保护氨基酸的羧酸,然后将氨基酸与DCC活化的乳清酸结合,然后除去羧酸保护基。 所得到的氨基酸乳清酸酰胺与相关酯相比在溶液中具有增强的稳定性。 此外,特别的益处是由用于形成化合物的具体氨基酸,除了和与乳清酸酯取代基分开外,还有其独特之处。
