A phosphodiesterase-4 inhibitor, commonly referred to as a PDE4 inhibitor, is a drug used to block the degradative action of phosphodiesterase 4 (PDE4) on cyclic adenosine monophosphate (cAMP). It is a member of the larger family of PDE inhibitors. The PDE4 family of enzymes are the most prevalent PDE in immune cells. They are predominantly ...
It inhibits PDE4 to the greatest extent, but also shows significant inhibition of other PDE subtypes, and so acts as a selective PDE4 inhibitor or a non-selective phosphodiesterase inhibitor, depending on the dose. Piclamilast, a more potent inhibitor than rolipram. [25] Luteolin, supplement extracted from peanuts that also possesses IGF-1 ...
Inhibitors of PDE can prolong or enhance the effects of physiological processes mediated by cAMP or cGMP by inhibition of their degradation by PDE. [13] Sildenafil (Viagra) is an inhibitor of cGMP-specific phosphodiesterase type 5, which enhances the vasodilatory effects of cGMP in the corpus cavernosum and is used to treat erectile dysfunction.
Apremilast is a small-molecule inhibitor of PDE4, [4] an enzyme that breaks down cyclic adenosine monophosphate (cAMP). [4] In inflammatory cells, PDE4 is the dominant enzyme responsible for this reaction.

It acts as a selective, long-acting inhibitor of the enzyme phosphodiesterase-4 (PDE-4). [10] It has anti-inflammatory effects. [10] [11] [12] It was approved for medical use in the European Union in 2010, [7] in the United States in 2011, [4] and in Canada in 2017. [1] It is available as a generic medication. [13]
Piclamilast (RP 73401), is a selective PDE4 inhibitor. [1] It is comparable to other PDE4 inhibitors for its anti-inflammatory effects. It has been investigated for its applications to the treatment of conditions such as chronic obstructive pulmonary disease, bronchopulmonary dysplasia and asthma.
Crisaborole is a phosphodiesterase-4 inhibitor, mainly acting on phosphodiesterase 4B (PDE4B), which causes inflammation. [6] Chemically, crisaborole is a phenoxybenzoxaborole . [ 6 ] Inhibition of PDE4B appears to suppress the release of tumor necrosis factor alpha (TNFα), interleukin-12 (IL-12), IL-23 and other cytokines , proteins believed ...
