Chemical Structure
L-Methionine-DL-sulfoximine
Synonym(s): MSX; MSO
- No. CAS: 15985-39-4
- Formula:C5H12N2O3S
- Molecular Weight:180.23
IUPAC Name: (2S)-2-amino-4-(S-methylsulfonimidoyl)butanoic acid
InChIKey: SXTAYKAGBXMACB-DPVSGNNYSA-N
SMILES: O=C(O)[C@@H](N)CCS(=N)(C)=O
Biological Activity: L-Methionine-DL-sulfoximine (MSX; MSO), a highly specific and irreversible inhibitor of Glutamine synthetase (GS), is also a potent convulsant which metabolically and morphologically primarily affects astroglia. L-Methionine-DL-sulfoximine has been employed to inhibit the Gln-dependent ammonia-stimulated neuronal toxicity in vitro, potentiating Gln deficit-dependent depression. L-Methionine-DL-sulfoximine tremendously increases the rate of release of fixed nitrogen in cyanobacteria. L-Methionine-DL-sulfoximine is a promising candidate for research in biofertilizers and convulsive seizures (CS)[1][2][3][4][5].
