4CD9
4CD9 is a chemical compound with the molecular formula C17H14N2O. It is a derivative of a purine base and is notable for its interaction with certain biological targets. Specifically, it has been identified as an inhibitor of the enzyme phosphodiesterase 4 (PDE4). PDE4 enzymes play a crucial role in cellular signaling pathways, particularly in the regulation of cyclic adenosine monophosphate (cAMP) levels. By inhibiting PDE4, 4CD9 can increase intracellular cAMP concentrations.
The modulation of cAMP levels has implications in various physiological processes, including inflammation and immune responses.
