Medchemexpress LLC Hordenine-d6 | 1346598-66-0 | 98.03% | 171.27 | 1 MG
Hordenine-d6 is a deuterium-labeled variant of Hordenine, an alkaloid naturally occurring in plants. The unlabeled form of Hordenine has been shown to inhibit melanogenesis by suppressing the production of cyclic adenosine monophosphate (cAMP). Deuterium-labeled compounds incorporate stable heavy isotopes of elements like hydrogen and carbon into drug molecules. This labeling technique is primarily used as a tracer for quantitative analysis during drug development, and it has garnered attention for its potential to influence the pharmacokinetic and metabolic profiles of drugs.
- Used as a tracer in research applications.
- Serves as an internal standard for quantitative analysis using techniques such as NMR, GC-MS, or LC-MS.
- Incorporation of stable heavy isotopes can affect the pharmacokinetic and metabolic profiles of compounds.
- It is a deuterium labeled compound.
