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.
