Methotrexate-methyl-d3

Methotrexate-methyl-d3 is a deuterated form of methotrexate, an antineoplastic and antirheumatic agent. Studies indicate that methotrexate-methyl-d3 can act as a folic acid antagonist. Methotrexate competitively and irreversibly inhibits dihydrofolate reductase (DHFR) which is essential in tetrahydrofolate synthesis. In addition, the reduction in tetrahydrofolate synthesis causes a decrease in purine base synthesis which results in the inhibition of DNA, RNA, thymidylates, and proteins. Alternate studies suggest that methotrexate-methyl-d3 can suppress T cell activation and adhesion molecule expression through IL-1 suppression.
