Methоtrexаte is а fоlаte antagоnist and an antimetabolite widely used in chemotherapy and the treatment of autoimmune diseases such as rheumatoid arthritis and psoriasis. Its primary mechanism of action involves the inhibition of dihydrofolate reductase (DHFR), an enzyme essential for the synthesis of tetrahydrofolate. Tetrahydrofolate is a critical cofactor in the synthesis of purine nucleotides and thymidylate, which are necessary for DNA replication and cell division. By inhibiting DHFR, methotrexate reduces the availability of tetrahydrofolate, thereby disrupting DNA synthesis, repair, and cellular replication. Increasing the Dihydrofolate may reverse the action of methotrexate.This action is particularly effective against rapidly dividing cells, such as cancer cells, but it also affects normal proliferating cells in the bone marrow, gastrointestinal tract, and hair follicles, leading to side effects such as myelosuppression, mucositis, and alopecia. In autoimmune diseases, methotrexate's anti-inflammatory effects are believed to be due to its ability to increase extracellular adenosine levels and inhibit T-cell activation, among other immunomodulatory actions. What type of an inhibitor is Methotrexate?
