This chemical is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methods. It serves as a building block for creating peptides with specific structural features, especially those involving pseudoproline dipeptides. The Fmoc group protects the amino terminus during synthesis, while the Boc group protects the lysine side chain, ensuring selective reactions. The pseudoproline moiety (Ser[Psi(Me,Me)Pro]) is particularly useful for improving peptide solubility and reducing aggregation during synthesis, which is critical for constructing complex or long peptide sequences. This compound is valuable in the development of therapeutic peptides, research peptides, and peptidomimetics, where precise control over peptide folding and stability is essential. Its application is also relevant in drug discovery and biochemical research, enabling the study of protein-protein interactions and enzyme mechanisms.
