Phenylethyl isothiocyanate (JC5411) is an HDAC inhibitor. It potentially for the treatment of benign prostatic hypertrophy.

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.

4-Pyridoxolactone (β-Pyracin) is a pivotal substrate in the vitamin B6 degradation pathway I, primarily involved in the vitamin B6 metabolism mediated by soil microorganisms. It serves as the specific substrate for 4-pyridoxolactonase, undergoing zinc-dependent lactone ring hydrolysis catalyzed by this enzyme to produce 4-pyridoxic acid.

Argifin is a chitinase inhibitor produced by the metabolism of soil microorganisms, with inhibitory activity at the sub-nanomolar level; its IC50 values against Serratia marcescens chitinase A and B, Aspergillus fumigatus chitinase B1 and human chitotriosidase are 0.025 μM, 6.4 μM, 1.1 μM and 4.5 μM, respectively [1].
