Medchemexpress LLC Methotrexate-d3 | 432545-63-6 | ≥99.0% | C20H19D3N8O5 | 1 MG
Methotrexate-d3 (Amethopterin-d3) is the deuterium labeled Methotrexate. Methotrexate (Amethopterin), an antimetabolite and antifolate agent, inhibits the enzyme dihydrofolate reductase, thereby preventing the conversion of folic acid into tetrahydrofolate, and inhibiting DNA synthesis. Methotrexate, also an immunosuppressant and antineoplastic agent, is used for the research of rheumatoid arthritis and a number of different cancers (such as acute lymphoblastic leukemia).
- Used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- 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.
