Used in biochemical and pharmaceutical research as a dipeptide building block for synthesizing larger peptides and proteins. Commonly employed in studies related to enzyme activity, receptor binding, and signal transduction due to the presence of aromatic amino acids. Serves as a model compound in metabolic stability tests and in the development of peptidomimetic drugs. Also utilized in cell culture applications to investigate peptide transport mechanisms and in the design of enzyme inhibitors, particularly for proteases that recognize phenylalanine and tyrosine residues.
