Used in research for studying protease activity and enzyme inhibition due to its peptide structure containing multiple hydrophobic amino acid residues. Commonly employed in the development of assay substrates for proteolytic enzymes, especially in cancer and neurodegenerative disease studies. Serves as a building block in solid-phase peptide synthesis for creating larger bioactive peptides or peptidomimetics. Its Boc-protected N-terminus allows for controlled stepwise synthesis in organic solvents. Also utilized in drug discovery to mimic natural peptide substrates and investigate structure-activity relationships in enzyme interactions.
