7-Hydroxy methotrexate-d3 (ammonium salt)
7-Hydroxy methotrexate-d3 (ammonium salt) is deuterium labeled 7-Hydroxymethotrexate. 7-Hydroxymethotrexate is a major metabolite of Methotrexate (MTX; HY-14519). Methotrexate, an antimetabolite and antifolate agent, inhibits the enzyme dihydrofolate reductase, thereby preventing the conversion of folic acid into tetrahydrofolate, and inhibiting DNA synthesis[3].
