Exploring the Diverse Uses of Aminopterin: From Leukemia Treatment to Cell Culture

Aminopterin,cas: 54-62-6 also known as 4-aminopteroic acid, is a synthetic derivative of pterin and a 4-amino derivative of folic acid. It is an antineoplastic drug with immunosuppressive properties, often used in chemotherapy. Aminopterin functions as an enzyme inhibitor by competing for the folate binding site of the enzyme dihydrofolate reductase, effectively blocking tetrahydrofolate synthesis. This leads to the depletion of nucleotide precursors and the inhibition of DNA, RNA, and protein synthesis.Discovered by Yellapragada Subbarow, Aminopterin was first used by Sidney Farber in [...]
