Abstract

Prodrugs made up of biologically-active short-chain fatty acids or derivatives thereof conjugated to neutral or cationic amino acids capable of intracellular transport by ATB⁰,⁺ are provided. The short-chain fatty acid or derivative thereof can be attached to the amino acid through a hydroxyl group of the amino acid to form a fatty acid ester of the amino acid, or it can be attached through the amino group of the amino acid to form a fatty-acid amide of the amino acid. Serine butyrate (O-butyryl serine) is a preferred prodrug. These prodrugs are useful for treatment of colon cancer, inflammatory bowel disease, ulcerative colitis, Crohn's disease, lung cancer, cervical cancer, and cancers resulting from metastases from primary colon cancer sites. Methods of delivering biologically-active short-chain fatty acids or derivatives thereof to cells in need of these molecules and methods of treating diseases using the prodrugs of this invention are also provided.
