Used in research as a potent and selective inhibitor of protein kinase C (PKC) isoforms, particularly PKCδ. It is employed in cellular and biochemical studies to investigate signal transduction pathways involving PKC, helping to elucidate the role of this enzyme family in processes such as cell proliferation, apoptosis, and inflammation. Due to its selectivity, it serves as a valuable tool compound in studies targeting PKC-related diseases, including cancer, neurodegenerative disorders, and diabetes complications.
