PDE9-IN-(S)-C33 ((S)-C33) is a potent and selective inhibitor of PDE9 (IC50 = 11 nM). PDE9-IN-(S)-C33 can be used for central nervous system diseases and diabetes research.

PF-04822163 is a potent inhibitor of PDE1 with IC50 value of 0.0024 μM.

PDE5-IN-2 is a potent, highly selective, and orally active inhibitor of PDE5 (IC50 of 0.31 nM).

PDE5-IN-6c is a potent and selective inhibitor of PDE5A1.

Fulvic Acid is a natural product of humus produced by microorganisms in soil, sediment or aquatic environments. Fulvic acid is a phenolic acid and fungal metabolite isolated from Penicillium for the first time. Fulvic Acid inhibits the dimerization of amyloid b (17-42) (AB17-42), destroys the pre-formed trimer of AB17-42, and binds to the catalytic site of phosphodiesterase 5A (PDE5A), which can regulate the body's immune system, affect the oxidation state of cells, and improve gastrointestinal function. Fulvic Acid can be used as an oxidant or reducing agent and has the potential to study chronic inflammatory diseases such as diabetes.

PDE1-IN-4 is a potent and selective inhibitor of PDE1 (phosphodiesterase-1), acting on PDE1C (IC50: 10 nM), PDE1A (IC50: 145 nM) and PDE1B (IC50: 354 nM). PDE1-IN-4 regulates cAMP (3′,5′-cyclic adenosine monophosphate) and cGMP (3′,5′-cyclic guanosine monophosphate) and exhibits antifibrotic effects. PDE1-IN-4 can inhibit TGF-β1-induced differentiation of human lung fibroblasts, and can be used to study idiopathic pulmonary fibrosis (IPF).

PDE4-IN-12 is a potent and safe ubiquitous PDE4 inhibitor with an IC50 of 3.5 nM (SI: 2.71) and also acts on PDE7 with an IC50 of 15 nM (SI: 4.27).

Moracin M, a phenolic compound found in the skin of Morus alba Linn., effectively inhibits phosphodiesterase-4 (PDE4), exhibiting IC50 values of 2.9 μM and 4.5 μM for PDE4D2 and PDE4B2, respectively, and showing significantly lesser activity on PDE5A1 and PDE9A2 with values over 40 μM and 100 μM, respectively. This compound demonstrates notable anti-inflammatory activity.
