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.

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.
