Beschreibung

Anwendung

Chelidamic acid hydrate has been used in eluent solution as a complexing additive in high-performance chelation ion chromatography (HPCIC) for speciation of iron.[1] It has also been used as an organic ligand for the polyoxometalate (POM)-based lanthanoid hybrid compounds.[2][3]

Biochem./physiol. Wirkung

Among the most potent of the tested "conformationally restricted glutamate analogs" as an inhibitor of glutamate decarboxylase.[4]

Chelidamic acid (CDA), a hydroxylated derivative of 2,6-pyridine-dicarboxylic acid (DPA)[5], is a trianionic chelating agent.[6]
