Used in peptide synthesis as an N-methylated D-amino acid building block, particularly in the development of bioactive peptides and pharmaceutical research. The D-configuration and N-methylation enhance metabolic stability, making it valuable in designing peptides with improved resistance to enzymatic degradation. Commonly employed in the production of synthetic analogs for structure-activity relationship (SAR) studies. Also utilized in the preparation of peptidomimetics for drug discovery, especially in oncology and endocrinology.
