Z-LVG-CHN2 is primarily used in biochemical research as a specific inhibitor of cysteine proteases. These enzymes play crucial roles in various biological processes, including protein degradation, immune response, and apoptosis. By inhibiting cysteine proteases, Z-LVG-CHN2 helps researchers study the function and regulation of these enzymes in cellular pathways. It is particularly valuable in understanding disease mechanisms where cysteine proteases are implicated, such as in cancer, inflammation, and parasitic infections. Additionally, it aids in the development of therapeutic agents targeting these enzymes for disease treatment.
