This compound is primarily used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) methodologies. The Fmoc (fluorenylmethyloxycarbonyl) group serves as a protecting group for the amine functionality, allowing for the stepwise assembly of peptides. The serine residue, modified with a pseudoproline moiety (ψMe,MePro), is incorporated to improve the efficiency of peptide chain elongation by reducing aggregation and secondary structure formation during synthesis. This modification is especially beneficial when synthesizing challenging or long peptide sequences, as it enhances solubility and minimizes side reactions. The compound is widely applied in the development of therapeutic peptides, peptide-based drugs, and biochemical research tools.
