Abstract
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.
