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.

A novel inorganic-organic hybrid, {Na[Tb(L)(H2O)4]3(SiW12O40)}·4H2O, in which L = 4-hydroxypyridine-2,6-dicarboxylic acid (chelidamic acid), was prepared and characterized by elemental analyses, Fourier transform infrared spectroscopy, and single-crystal X-ray diffraction. It consists of a trinuclear terbium cluster bonded to a Keggin-type polyoxotungstate.
