Used as a potent and selective inhibitor of protein kinase C (PKC) in cellular signaling research. It helps modulate PKC-mediated pathways involved in cell proliferation, differentiation, and apoptosis. Commonly applied in studies related to cancer, neurodegenerative diseases, and inflammation to assess the role of PKC isoforms. Its selectivity makes it valuable for probing specific kinase functions without significant off-target effects in biochemical assays and cell-based models.
