Used primarily in biochemical research as a potent inhibitor of aspartic proteases, including pepsin, cathepsin D, and renin. It is widely applied in studies to understand enzyme mechanisms and to block protease activity in experimental setups. Additionally, it aids in the investigation of protein degradation pathways and the role of proteases in disease processes, such as cancer and neurodegenerative disorders. Its application extends to the development of therapeutic strategies targeting protease-related conditions.
