Used in pharmaceutical research as a building block for synthesizing peptide-based drugs, particularly those targeting specific enzymes or receptors. Its structure allows for the development of compounds with enhanced stability and bioavailability. It is also employed in biochemical studies to investigate cysteine-related metabolic pathways and enzyme mechanisms. Additionally, it serves as a precursor in the preparation of modified peptides for therapeutic applications, such as anticancer or antimicrobial agents. Its methoxybenzyl group provides unique properties that can influence drug delivery and target specificity.
