Used primarily in biochemical research, this compound is a potent inhibitor of caspases, which are enzymes involved in programmed cell death. It is applied in studies to understand apoptosis mechanisms and to investigate pathways that regulate cell survival and death. Researchers utilize it to block caspase activity, allowing them to dissect the roles of specific caspases in cellular processes. It is also employed in drug discovery to identify potential therapeutic agents targeting apoptosis-related diseases, such as cancer and neurodegenerative disorders. Its application extends to in vitro assays and experimental models to explore cell death pathways and their implications in health and disease.
