PKC-IN-1 is primarily used in biochemical research as a potent and selective inhibitor of protein kinase C (PKC) isoforms. Its application is crucial in studying the role of PKC in various cellular processes, including signal transduction, cell proliferation, and apoptosis. Researchers utilize PKC-IN-1 to investigate the therapeutic potential of PKC inhibition in diseases such as cancer, cardiovascular disorders, and neurodegenerative conditions. By blocking PKC activity, it helps in understanding the molecular mechanisms underlying these diseases and in developing targeted treatment strategies. Additionally, PKC-IN-1 is employed in pharmacological studies to assess the efficacy and specificity of PKC inhibitors in preclinical models.
