This chemical is primarily used in peptide synthesis, particularly in the construction of peptide analogs with modified peptide bonds. The incorporation of the pseudoproline dipeptide mimic helps to improve the solubility and reduce aggregation during solid-phase peptide synthesis, making it easier to handle and synthesize complex peptides. It is especially valuable in the synthesis of challenging sequences, such as those prone to secondary structure formation. The Fmoc-protecting group ensures selective deprotection during the synthesis process, allowing for stepwise elongation of the peptide chain. Its application is significant in the development of therapeutic peptides, peptidomimetics, and research tools for studying protein structure and function.
