4-Amino-DL-phenylalanine, also known as 4-Amino-phenylalanine or DL-4-Aminophenylalanine, is an amino acid derivative characterized by the presence of an amino group (-NH2) at the para position of the phenyl ring relative to the carboxylic acid group. This compound is a racemic mixture of its D and L isomers, which means it contains equal amounts of both enantiomers. It is soluble in water and exhibits properties typical of amino acids, such as the ability to participate in peptide bond formation. The presence of the amino group contributes to its basicity, while the phenyl group provides hydrophobic characteristics. 4-Amino-DL-phenylalanine is of interest in biochemical research and may have applications in the study of neurotransmitter synthesis and metabolism. Additionally, it can serve as a building block in the synthesis of various pharmaceuticals and biologically active compounds. Safety and handling precautions should be observed, as with all chemical substances, due to potential toxicity and reactivity.

4-Amino-DL-phenylalanine (4AP) is an inhibitor that binds to the receptor binding site on the surface glycoprotein of E. coli, thereby inhibiting the attachment of this bacterium to host cells. 4AP has been shown to inhibit the growth of pathogens such as Salmonella enterica serotype Typhi, Shigella flexneri, and Pseudomonas aeruginosa. 4AP also has a hydroxyl group that can react with other molecules by transfer reactions, which may be important for its antimicrobial activity. The chemical stability of 4AP allows it to maintain its biological properties in vivo. The optimum pH for 4AP’s antimicrobial activity is 7.4.
