Used as a selective protein kinase C (PKC) inhibitor in cellular and biochemical research. It helps study signal transduction pathways by blocking PKC activity, which plays a role in cell proliferation, differentiation, and apoptosis. Commonly applied in studies related to cancer, neuroscience, and cardiovascular diseases to investigate the role of PKC isoforms. Also used in assays to determine the involvement of PKC in receptor-mediated responses and intracellular signaling mechanisms.
