The present invention describes compounds produced from an orotic acid molecule and an ammo acid molecule The compounds, which include an amide linkage, are represented by the general Formula (I), wherein R is selected from the group consisting of (CH3)2CHCH2-, (CH3)2CH-, CH3CH2CH(CH3)-, H2NC(=NH)NH(CH2)3-, and C6H5CH2- Formula (I). The compounds are 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 ammo acid in the presence of dichloromethane and a dimethylammopyπdme (DMAP) catalyst, or 2) protecting the carboxylic acid of an ammo acid with a benzyl group, and then combining the benzyl-protected ammo acid with a dicyclohexylcarbodiimide (DCC) activated orotic acid, followed by removal of the protecting group. The resulting ammo acid orotate amide compounds are aimed at providing enhanced stability in solution compared with the related esters.
该发明描述了由乳酸分子和氨基酸分子产生的化合物。这些化合物包括酰胺键,由通用式(I)表示,其中R选自(CH3)2CHCH2-、(CH3)2CH-、CH3CH2CH(CH3)-、H2NC(=NH)NH(CH2)3-和C6H5CH2-。这些化合物由两种方法之一制备:1)将乳酸或其衍生物与硫酰卤反应,然后在二氯甲烷和二甲基氨基吡啶(DMAP)催化剂存在下将酰卤与氨基酸结合;2)用苄基保护氨基酸的羧基,然后将苄基保护的氨基酸与二环己基碳二亚胺(DCC)活化的乳酸结合,然后去除保护基。最终产生的氨基酸乳酸酰胺化合物旨在在溶液中提供比相关酯更强的稳定性。
