PC1 Activators

PC1 Activators are a suite of chemical compounds that indirectly promote the functional activity of PC1 through a variety of cellular signaling pathways, predominantly involving the cyclic AMP (cAMP) second messenger system. Compounds such as Forskolin, Isoproterenol, Glucagon, Terbutaline, and Salmeterol exert their effects by activating adenylate cyclase or binding to beta-adrenergic receptors, which in turn increases intracellular levels of cAMP. The rise in cAMP activates protein kinase A (PKA), which is known to phosphorylate target proteins and can lead to the enhanced activity of PC1 by either direct phosphorylation or by modifying the phosphorylation state of proteins within PC1's signaling network.

Similarly, the inhibition of phosphodiesterases, which degrade cAMP, by IBMX, Rolipram, Anagrelide, Cilostamide, Zardaverine, and Milrinone also results in an increase in cAMP levels, thereby sustaining PKA activity and promoting an environment conducive to the functional enhancement of PC1.
