Medchemexpress LLC Darutoside | 59219-65-7 | 5 MG

Darutoside is an orally effective diterpene compound with significant anti-inflammatory, analgesic, wound healing promotion, and immunomodulatory activities. It reduces edema and pain by inhibiting COX-2 expression and inflammatory cell migration, and regulates macrophage polarization towards the M2 type by inhibiting the NF-κB pathway, which alleviates inflammation and promotes wound healing. Additionally, it significantly alleviates acute gouty arthritis through multi-target regulation of metabolic networks.

Medchemexpress LLC Felbamate-d4 | 106817-52-1 | 97.2% | 1 MG

Felbamate-d4 (W-554-d4) is the deuterium labeled Felbamate. Felbamate (W-554) is a potent anticonvulsant whose clinical effect may be related to the inhibition of N-methyl-D-aspartate (NMDA). Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.

This compound can be used as a tracer.
This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
