Methotrexate (MTX) is an antifolate metabolite that inhibits DNA synthesis, repair and cellular replication.

[6] Methotrexate reduces the rate of cell proliferation, increases the rate of T-cell apoptosis, increases endogenous concentrations of adenosine, and alters the production of cytokines and humoral responses.

.

Although methotrexate is one of the first examples of intelligent drug design, multiple mechanisms potentially contribute to the anti-inflammatory actions of methotrexate, including the inhibition of purine and pyrimidine synthesis, transmethylation reactions, translocation of nuclear factor-κB (NF-κB) to the nucleus, signalling via the Janus. .
