Medchemexpress LLC L-Methionine-DL-sulfoximine | 15985-39-4 | 98.0% | 1 G
L-Methionine-DL-sulfoximine (MSX; MSO) is a highly specific and irreversible inhibitor of Glutamine synthetase (GS). It acts as a potent convulsant, primarily affecting astroglia metabolically and morphologically. This compound has been utilized to inhibit Gln-dependent ammonia-stimulated neuronal toxicity in vitro and significantly increases the release rate of fixed nitrogen in cyanobacteria. It is considered a promising candidate for research in biofertilizers and convulsive seizures (CS).
- Highly specific and irreversible inhibitor of glutamine synthetase.
- Potent convulsant affecting astroglia.
- Inhibits Gln-dependent ammonia-stimulated neuronal toxicity in vitro.
- Increases release rate of fixed nitrogen in cyanobacteria.
- Potential for research in biofertilizers and convulsive seizures.
Medchemexpress LLC Sinapyl alcohol-d3 1mg
Sinapyl alcohol-d3 is the deuterated labeled Sinapyl alcohol (HY-W109812) Sinapyl alcohol is an orally active anti-inflammatory and antinociceptive agent Sinapyl alcohol reduces the expression level of inducible NO synthase and COX-2[1]
Medchemexpress LLC Telmisartan-d7 (BIBR 277-d7) | 1794754-60-1 | 99.6% | 521.66 | 1 MG
Telmisartan-d7 (BIBR 277-d7) is a deuterium labeled Telmisartan, a potent and long-lasting antagonist of angiotensin II type 1 receptor (AT1). It selectively inhibits the binding of 125I-AngII to AT1 receptors with an IC50 of 9.2 nM. Deuteration can affect the pharmacokinetic and metabolic profiles of drugs, and stable heavy isotopes are often incorporated into drug molecules as tracers for quantitation during drug development.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
