Medchemexpress LLC Diclofenac-d4 | 153466-65-0 | C14H7D4Cl2NO2 | 5 MG
Diclofenac-d4 is a deuterium labeled form of Diclofenac, a potent and nonselective anti-inflammatory agent that acts as a COX inhibitor. It has been shown to induce apoptosis of neural stem cells (NSCs) via the activation of the caspase cascade. Incorporating stable heavy isotopes like deuterium allows for its use as a tracer for quantitative analysis during drug development, potentially influencing pharmacokinetic and metabolic profiles.
- Deuterium labeled compound
- Potent and nonselective anti-inflammatory agent
- Acts as a COX inhibitor
- Induces apoptosis of neural stem cells
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS

Medchemexpress LLC Rosiglitazone-d3 | 1132641-22-5 | 97.2% | 360.45 | 1 MG
Rosiglitazone-d3 is the deuterium labeled Rosiglitazone. Rosiglitazone is a selective, orally active PPARγ agonist with EC50s of 30 nM, 100 nM, and 60 nM for PPARγ1, PPARγ2, and PPARγ, respectively. It binds to PPARγ with a Kd of approximately 40 nM and is also an activator of TRPC5 and an inhibitor of TRPM3. Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules as tracers for quantitation during drug development. Deuteration has gained attention due to its potential to affect the pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
