Used in research to activate protein kinase A (PKA) selectively, particularly in studies related to cell signaling, metabolism, and gene expression. It is valued for its ability to resist degradation by phosphodiesterases, making it more stable than cAMP in experimental settings. Commonly applied in studies of neuronal function, insulin secretion, and cardiac muscle regulation. Also investigated for potential roles in cancer research due to its influence on cell proliferation and differentiation.
