General description

Chemical structure: amino acid derivatives

Application

6-Diazo-5-oxo-L-norleucine (DON) has been used as an inhibitor of glutamine synthetase–glutamine(amide)-2-oxoglutarate aminotransferase.

Biochem/physiol Actions

6-Diazo-5-oxo-L-norleucine (DON), a glutamine analogue, is used as an inhibitor to study the function, specificity and characteristics of cytidine triphosphate synthase 1(s) (CTPS1) and various glutaminase(s). DON is used to inhibit glutamine (GLN) flux between cells.
DON is associated with a number of reactions involving L-glutamine as a nitrogen source, such as nucleic acid and protein synthesis. It is known to possess anticancer activity against choriocarcinoma.
DON is used to study mechanisms of glutamine utilizing enzymes such as carbamoyl phosphate synthase and cytidine triphosphate synthase.
