Sodium methotrexate

Methotrexate Sodium is the sodium salt of methotrexate, an antimetabolite with antineoplastic and immunomodulating properties. Methotrexate binds to and inhibits the enzyme dihydrofolate reductase, resulting in inhibition of purine nucleotide and thymidylate synthesis and, subsequently, inhibition of DNA and RNA syntheses. Methotrexate also exhibits potent immunosuppressant properties. Its therapeutic use is listed as anti-psoriatic agents, antineoplastics and antirheumatic agents. The directory classifies it as a commercial API with a synthetic source/manufacturing origin. Other names for this substance include Abitrexate, Trexall, Folex Pfs and Mexate. Its PubChem CID is 11329481.
