This compound is primarily used in biochemical research as a selective inhibitor of serine proteases, particularly elastase. It functions by irreversibly binding to the active site of the enzyme, thereby inhibiting its activity. Researchers utilize it to study the role of elastase in various physiological and pathological processes, such as inflammation and tissue remodeling. Additionally, it is employed in the development of therapeutic agents targeting elastase-related diseases, including chronic obstructive pulmonary disease (COPD) and cystic fibrosis. Its application extends to the investigation of protease mechanisms and the design of enzyme inhibitors in drug discovery.
