glutamine synthetase

L-Methionine-DL-sulfoximine (MSO) inhibits glutamine synthetase and metabolically and morphologically primarily affects astroglia. L-Methionine-DL-sulfoximine can be used in convulsant studies.

JFD01307SC ([(1,1-DIOXIDOTETRAHYDROTHIEN-3-YL)AMINO]) is a glutamine synthetase inhibitor. It is anti-tuberculosis agent and acts as a mimic of L-Glutamate and thus target enzymes involved in glutamine biosynthesis.

Albizziin is amino acid analog which acts as a competitive inhibitor of asparagine synthetase with respect to glutamine. Albizziin has been used to isolate mutants of Chinese hamster ovary cells with alterations in levels of the target enzyme. Several classes of mutations can be distinguished on the basis of cross-resistance to beta-aspartyl hydroxamate, another amino acid analog. Studies on asparagine synthetase indicate that resistance to albizziin may be due to altered regulation of asparagine synthetase, structural mutations of the enzyme, and gene amplification.

Methionine sulfoximine (MSO) is an irreversible glutamine synthetase inhibitor. It is the sulfoximine derivative of methionine with convulsant effects.

Acivicin hydrochloride is the hydrochloride form of Acivicin (AT125, U42126).Acivicin, a natural product from Streptomyces sviceus (Streptomyces), is a glutamine analog and a potent inhibitor of γ-glutamyltransferase (GGT) and a potent inhibitor of l -Asparagine synthetase and other l-glutamine aminotransferases, and is cytotoxic by blocking nucleotide biosynthesis.

Temtokibart is a humanized IgG1 λ2 antibody that specifically targets IL22RA1, expressed by cells deficient in the glutamine synthetase gene [glutamine synthetase deficient cells].
