Summary

Methotrexate (Amethopterin) disodium, an antimetabolite and antifolate agent, inhibits the enzyme dihydrofolate reductase , thereby preventing the conversion of folic acid into tetrahydrofolate, and inhibiting DNA synthesis. Methotrexate disodium, also an immunosuppressant and antineoplastic agent, is used for the research of rheumatoid arthritis and a number of different cancers (such as acute lymphoblastic leukemia) [1] [2] [3] .


IC50 & Target

Traditional Cytotoxic Agents


In Vivo

Methotrexate (Amethopterin) disodium reduces thymus and spleen indices of mice. Methotrexate disodium markedly decreases white blood cells, thymic and splenic lymphocytes at dose ≥5 mg/kg. However, there is a significant difference between the treatment plus control group and the model group (p<0.01). The combination of grape seed proanthocyanidins and Siberian ginseng eleutherosides obviously diminishes the effects of Methotrexate exposure on indices of thymus and spleens in mice [2] .
Methotrexate (MTX) disodium (2 mg/kg; i.p.; once in a week for 5 weeks) is effective in Freund's complete adjuvant-induced arthritis. The combination of Methotrexate disodium (1 mg/kg; i.p.; once in a week for 5 weeks) and Curcumin (30 mg/kg and 100 mg/kg, thrice a week for 5 weeks; i.p.) shows a significant anti-arthritic action and protection from hematological toxicity [4] .

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
