Methotrexate
Chemical Name: N-[4-[[(2,4-Diamino-6-pteridinyl)methyl]methylamino]benzoyl]-L-glutamic acid
Purity: ≥99%
Biological Activity
Methotrexate is a cytotoxic agent. Inhibits thymidylate synthetase and de novo purine synthesis. Potent folic acid antagonist; inhibits dihydrofolate reductase. Also inhibits Ras carboxyl methylation in DKOB8 cells, leading to decreased p44 and Akt activation.Technical Data
