Aminopterin (4-Aminofolic acid), the 4-amino derivative of folic acid, is a folic acid antagonist. Aminopterin catalyses the reduction of folic acid to tetrahydrofolic acid, and competitively inhibits dihydrofolate reductase (DHFR) with a Ki of 3.7 pM. Aminopterin has anticancer and immunosuppressive activity. Aminopterin is used in treatment of pediatric leukemia[1][2].
In Vitro: The IC50 value of Aminopterin (4-Aminofolic acid) against CCRF-CEM cells during 72 h of exposure is 4.4 nM[2].
Aminopterin (4-Aminofolic acid) produces a marked inhibition of mitosis in low concentrations in human leukemic leukocytes[4].
