PDE4-IN-4 is a compound acting as both a potent M3 antagonist (p IC 50 = 10.2) and a PDE4 inhibitor (p IC 50 = 8.8), designed for inhalation-based treatment of pulmonary diseases.
PDE4-IN-3 is a newly developed oral compound that acts as a potent inhibitor of the enzyme phosphodiesterase 4 (PDE4), displaying a high affinity for inhibition with an IC50 value of 4.2 nM.
PDE7 inhibitor S14 is a cell-permeable PDE7 inhibitor that acts by targeting the cyclic adenosine monophosphate (cAMP) cAMP-response element-binding protein (CREB) pathway.
PDE12-IN-1 is a powerful and specific inhibitor of PDE12, exhibiting a pIC 50 value of 9.1 for enzyme inhibition. It effectively enhances levels of 2′,5′-linked adenylate polymers (2-5A), with a pEC 50 value of 7.7. Additionally, PDE12-IN-1 demonstrates antiviral activity.
