Synthesis method
By2,4,5,6- It is obtained by cyclizing tetraaminopyrimidine with dibromopropionaldehyde and then condensing it with p-methylaminobenzoylglutamic acid.
Purpose
Folic acid antagonizes Liu. A potent inhibitor of dihydrofolate reductase. Immunosuppressants. Tissue culture reagents.
This product is a good anti-tumor drug, used for acute lymphoblastic leukemia, lymphoma, malignant mole, choriocarcinoma, and squamous epithelium cancer, lung cancer, cervical cancer, breast cancer and osteosarcoma, etc. Oral methotrexate12hAfter the original drug90%Excreted in urine, the main metabolite is7-Hydroxymethotrexate. Intravenous injection in ratsLD50 for14mg/kg.
