H-7 is widely used in biochemical research as a potent and selective inhibitor of protein kinase C (PKC). It plays a crucial role in studying cellular signaling pathways, particularly those involving PKC-mediated processes. Researchers utilize H-7 to investigate the mechanisms of cell proliferation, differentiation, and apoptosis, as PKC is involved in regulating these functions. Additionally, H-7 is employed in studies exploring the role of PKC in various diseases, such as cancer, cardiovascular disorders, and neurological conditions. Its ability to inhibit PKC activity helps in understanding the therapeutic potential of targeting this enzyme in drug development. H-7 is also used in experimental models to dissect the contributions of PKC in immune responses and inflammation.
