生物活性

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.

体外研究

The IC50 value of Aminopterin (4-Aminofolic acid) against CCRF-CEM cells during 72 h of exposure is 4.4 nM.
Aminopterin (4-Aminofolic acid) produces a marked inhibition of mitosis in low concentrations in human leukemic leukocytes.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
