Used in biochemical and pharmaceutical research as a key intermediate in the synthesis of quinoline-based compounds with potential therapeutic activity. Shows relevance in studies targeting neurological pathways due to structural similarity to amino acids involved in neurotransmission. Also employed in the development of enzyme inhibitors, particularly for proteases and kinases, owing to its ability to mimic natural substrates. Its zwitterionic nature and hydrogen bonding capacity make it useful in crystallography studies for analyzing protein-ligand interactions. Additionally, it serves as a building block in the design of peptidomimetic drugs aimed at improving metabolic stability and bioavailability.
