This compound is widely used in biochemical and pharmacological research as a selective inhibitor of cyclic AMP-dependent protein kinase (PKA). It is particularly valuable in studies aimed at understanding the role of PKA in cellular signaling pathways. Researchers utilize it to investigate the effects of PKA inhibition on various physiological processes, including metabolism, gene expression, and cell proliferation. Additionally, it serves as a tool to dissect the contributions of PKA in disease models, such as cancer, cardiovascular disorders, and neurological conditions. Its application extends to in vitro and in vivo experiments, helping to elucidate the mechanisms of cAMP-mediated signaling and its impact on cellular function.
