SZL P1-41 is primarily used in research settings as a potent and selective inhibitor of the kinase enzyme TBK1 (TANK-binding kinase 1). Its application is significant in studying cellular signaling pathways, particularly those involved in immune responses and inflammation. Researchers utilize SZL P1-41 to investigate the role of TBK1 in diseases such as cancer, autoimmune disorders, and viral infections. By inhibiting TBK1, it helps elucidate the enzyme's function in regulating processes like autophagy, interferon production, and cell survival. This makes it a valuable tool for developing targeted therapies and understanding disease mechanisms at the molecular level.
