SM-164 is primarily used in biochemical research as a potent inhibitor of IAP (Inhibitor of Apoptosis Proteins). It is particularly valuable in studies focused on understanding apoptosis, or programmed cell death, and its role in cancer development and treatment. By inhibiting IAPs, SM-164 promotes apoptosis in cancer cells, making it a useful tool in exploring potential cancer therapies. Researchers also utilize SM-164 to investigate the mechanisms of cell survival and resistance to apoptosis, which can provide insights into improving the efficacy of anticancer drugs. Additionally, it is employed in laboratory settings to study the signaling pathways involved in cell death and survival, contributing to the broader understanding of cellular processes and disease mechanisms.
