Product Description: 7-Hydroxymethotrexate-d3 (ammonium) is the deuterium labeled 7-Hydroxymethotrexate ammonium. 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[1][2].
Applications: Metabolism-protein/nucleotide metabolism
Formula: C20H22D3N9O6
