Aminopterin

EPA Extremely Hazardous Substances List.

The Aminopterin, with the CAS registry number 54-62-6, is also known as N-[4-[[(2,4-Diamino-6-pteridinyl)methyl]amino]benzoyl]-L-glutamic acid. It belongs to the product categories of Amino Acids 13C, 2H, 15N; Amino Acids & Derivatives; Aromatics; Inhibitors; Heterocycles; Intermediates & Fine Chemicals; Pharmaceuticals. Its EINECS registry number is 200-209-9. This chemical's molecular formula is C₁₉H₂₀N₈O₅ and molecular weight is 440.41. What's more, its IUPAC name is called (2S)-2-[[4-[(2,4-Diaminopteridin-6-yl)methylamino]benzoyl]amino]pentanedioic acid. It should be stored in a sealed and dry place. This chemical can be used as a folic acid antagonist. Its actively transported into cells by thefolate transporter. In the cell, its converted to a high molecular weight polyglutamate metabolite by folylpolyglutamate synthase, that, in turn, binds to dihydrofolate reductase.
