General description

Methotrexateis an analog of folate. It shows anti-inflammatory effects throughseveral cellular mechanisms. The inhibition of dihydrofolate reductase reducesthe de novo synthesis of pyrimidines and purines, transmetylation ofphospholipids and proteins, and formation of polyamines.

Application

Methotrexatehydrate has been used as a disease modifyinganti-rheumatic drug (DMARD) to study its effects on Ross River virus disease (RRVD) in mice models.
Potent inhibitor of dihydrofolate reductase and agent for antitumor studies. Use to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also effective in treatment of pyrimethamine-resistant Plasmodium vivax malaria parasites.
Potent inhibitor of dihydrofolate reductase and agent for antitumor studies. Use to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also shows immunosuppressive effects in, e.g., rheumatoid arthritis.

Other Notes

Folic acid antagonist. Potent inhibitor of dihydrofolate reductase.

Methotrexate remains a cornerstone in the treatment of rheumatoid arthritis and other rheumatic diseases. Folate antagonism is known to contribute to the antiproliferative effects that are important in the action of methotrexate against malignant diseases, but concomitant administration of folic

Because of methotrexate's well-documented efficacy in the treatment of rheumatoid arthritis, it is important that we understand the mechanism of action of this drug. There are two biochemical mechanisms by which methotrexate may modulate inflammation: (1) promotion of adenosine release
