Used in biochemical research as a peptide analog to study enzyme activity and metabolic pathways involving gamma-aminobutyric acid (GABA). Serves as a building block in the synthesis of modified peptides for pharmaceutical development. Investigated for its potential role in enhancing blood-brain barrier permeability due to its structural similarity to GABA. Also employed in assays to evaluate peptidase substrates and inhibitors, aiding in drug discovery for neurological disorders.
