Used in the synthesis of complex peptide-based pharmaceuticals, particularly as an intermediate in the development of protease inhibitors. Its structural features enable selective binding to enzyme active sites, making it valuable in designing drugs for viral infections and certain cancers. The compound’s chiral centers and functional groups support high specificity in biological targeting, especially in therapies requiring precise molecular recognition. It is also employed in research settings to study enzyme-substrate interactions and improve metabolic stability in peptide analogs.
