This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methodologies. The Fmoc group serves as a protecting group for the amine functionality, ensuring selective deprotection during the synthesis process. The tert-butyl (tBu) group protects the hydroxyl group of tyrosine, while the psiMe and Mepro modifications on threonine enhance stability and control stereochemistry during peptide chain assembly. This compound is valuable in the production of complex peptides and peptidomimetics, often employed in pharmaceutical research for developing therapeutic agents, enzyme inhibitors, or bioactive peptides. Its application is crucial in constructing peptides with specific structural and functional properties, aiding in drug discovery and biochemical studies.
