Methionine sulfoximine (MSO) is an irreversible glutamine synthetase inhibitor. It is the sulfoximine derivative of methionine with convulsant effects. Methionine sulfoximine is composed of two different diastereomers, which are L-S-Methionine sulfoximine and L-R-Methionine sulfoximine. These affect the longevity of the model mouse for Lou Gehrig's disease. Overproduction of glut… WebSince glucose is the main cerebral substrate, we have characterized the metabolism of various 13 C glucose isotopomers in rat brain slices. For this, we have used our cellular metabolomic approach that combines enzymatic and carbon 13 NMR techniques with mathematical models of metabolic pathways.
