DYRKs-IN-1 is primarily used in biochemical research to study the role of dual-specificity tyrosine phosphorylation-regulated kinases (DYRKs) in cellular processes. It serves as a potent inhibitor, helping scientists understand the mechanisms of these kinases in diseases such as Alzheimer's, Down syndrome, and cancer. By blocking DYRK activity, researchers can explore its impact on cell proliferation, differentiation, and apoptosis. This compound is also valuable in drug discovery efforts, aiding in the development of targeted therapies for conditions linked to DYRK dysregulation. Its application extends to neurobiology, where it helps investigate neuronal development and function.
