Medchemexpress LLC Galanthamine-d6 | 1128109-00-1 | 99.5% | C17H15D6NO3 | 1 MG
Galanthamine-d6 (Galantamine-d6) is a deuterium-labeled Galanthamine, known as a potent acetylcholinesterase (AChE) inhibitor with an IC50 of 500 nM. This compound is intended for research use only and can be utilized as a tracer or an internal standard for quantitative analysis by methods like NMR, GC-MS, or LC-MS. Stable heavy isotopes have been incorporated into drug molecules for quantitation during drug development, with deuteration potentially affecting pharmacokinetic and metabolic profiles.
- Used as a tracer
- Used as an internal standard for quantitative analysis
- Deuterium-labeled compound
- Potent acetylcholinesterase (AChE) inhibitor
Medchemexpress LLC Sarcosine-d3 25mg
Sarcosine-d3 is the deuterium labeled Sarcosine Sarcosine (N-Methylglycine) an endogenous amino acid is a competitive glycine transporter type I (GlyT1) inhibitor and N-methyl-D-aspartate (NMDA) receptor co-agonist Sarcosine increases the glycine concentration resulting in an indirect potentiation of the NMDA receptor Sarcosine is commonly used for the research of schizophrenia1]2]

Medchemexpress LLC 5-Fluorouracil-15N2 | 68941-95-7 | 99.0% | C4H3F15N2O2 | 1 MG
5-Fluorouracil-15N2 is the 15N-labeled 5-Fluorouracil. 5-Fluorouracil (5-FU) is an analogue of uracil and a potent antitumor agent. It affects pyrimidine synthesis by inhibiting thymidylate synthetase, thus depleting intracellular dTTP pools. 5-Fluorouracil induces apoptosis and can be used as a chemical sensitizer, and it also inhibits HIV.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
