Used as a potent and selective inhibitor of protein kinase C (PKC) enzymes, particularly effective in research settings to study signal transduction pathways. Commonly applied in cellular and molecular biology to investigate the role of PKC in cell proliferation, apoptosis, and neurotransmitter release. Widely utilized in neuroscience research due to its ability to cross the blood-brain barrier, making it suitable for studies on neuronal function and neurodegenerative diseases. Also employed in cancer research to explore the involvement of PKC isoforms in tumor progression and to evaluate potential therapeutic strategies. Its selectivity helps minimize off-target effects in experimental models.
