Beschreibung

Application

Chelidamic acid hydrate has been used in eluent solution as a complexing additive in high-performance chelation ion chromatography (HPCIC) for speciation of iron. It has also been used as an organic ligand for the polyoxometalate (POM)-based lanthanoid hybrid compounds.

Biochem/physiol Actions

Chelidamic acid (CDA), a hydroxylated derivative of 2,6-pyridine-dicarboxylic acid (DPA), is a trianionic chelating agent.

Among the most potent of the tested "conformationally restricted glutamate analogs" as an inhibitor of glutamate decarboxylase.
