Sp-5,6-dichloro-cBIMPS sodium salt is primarily used in biochemical research as a potent and selective activator of cyclic AMP-dependent protein kinase (PKA). Its application is significant in studying cellular signaling pathways, particularly those involving cAMP and PKA. Researchers utilize this compound to investigate the role of PKA in various physiological processes, such as cell metabolism, gene expression, and neuronal signaling. It is also employed in experiments to understand the mechanisms of hormone action and to explore the effects of PKA activation in different cell types. Additionally, Sp-5,6-dichloro-cBIMPS sodium salt is valuable in pharmacological studies aimed at developing therapeutic agents targeting PKA-related pathways.
