STK16-IN-1 is primarily utilized in biochemical research to study the role of STK16 kinase in cellular processes. It serves as a selective inhibitor, allowing researchers to investigate the kinase's function in signaling pathways, particularly those related to cell proliferation and survival. By blocking STK16 activity, this compound helps in understanding its potential involvement in diseases such as cancer, where kinase signaling is often dysregulated. Additionally, STK16-IN-1 is used in drug discovery efforts to identify and develop targeted therapies for conditions linked to abnormal kinase activity. Its application is essential in advancing knowledge of cellular mechanisms and exploring new therapeutic strategies.
