Methotrexate disodium
Based on 80 publication(s) in Google Scholar
Methotrexate disodium (Amethopterin disodium; CL14377 disodium; WR19039 disodium) is an orally active antifolate (Antifolate). Methotrexate disodium inhibits dihydrofolate reductase (DHFR), blocks tetrahydrofolate production, suppresses purine/pyrimidine synthesis and transmethylation, and causes intracellular accumulation of AICAR. Methotrexate disodium promotes extracellular adenosine release, regulates the cytokine network, and inhibits the alarmin function of HMGB1. Methotrexate disodium induces apoptosis and cytotoxicity, upregulates the expression of iNOS and COX-2, suppresses hippocampal neurogenesis, and induces pulmonary fibrosis. Methotrexate disodium is used in the research of various immune and inflammation-related diseases such as arthritis, psoriasis, systemic lupus erythematosus, as well as pulmonary fibrosis and breast cancer.

Methotrexate disodium at high concentrations stimulates adenosine secretion of endothelial cells, fibroblasts and peripheral blood monocytes, and this effect is amplified under metabolic stress; it further modulates macrophage function through adenosine and suppresses peripheral blood mononuclear cells from producing immunoglobulins, rheumatoid factors and spontaneous IL-8, which may be attributed to the reduction of intracellular polyamine levels[1].
Methotrexate (MTX) (0.01-100 μM; 72 h) disodium induces dose-dependent cytotoxicity in primary mouse alveolar epithelial cells (MAEC) and primary mouse lung fibroblasts (MLF)[4].
Methotrexate (1 μM; 12-48 h) disodium induces significant time-dependent apoptosis in primary mouse alveolar epithelial cells (MAEC), but exerts no significant pro-apoptotic effect on primary mouse lung fibroblasts (MLF) under the same conditions[4].
Methotrexate (0.5-5 μM; 24 h) disodium dose-dependently enhances cytotoxicity and reduces cell viability in FM3A breast cancer cells[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Methotrexate (3 mg/kg; p.o.; daily; days 21-35) disodium induces pulmonary fibrosis in male C57BL/6J mice in a time-dependent manner[4].
Methotrexate (40 mg/kg; i.p.; single dose) disodium induces hippocampal dysfunction in both FM3A-inoculated breast cancer mice and tumor-free healthy mice, including significant depression-like behaviors, cognitive impairment, reduced hippocampal neurogenesis, and upregulated expression of pro-inflammatory enzymes[5].
Methotrexate (MTX) (2 mg/kg; i.p.; once weekly for 5 consecutive weeks) disodium is effective against Freund's complete adjuvant-induced arthritis[6].
Methotrexate (1 mg/kg, intraperitoneal injection, once a week for 5 weeks) disodium combined with Curcumin (HY-N0005, 30 mg/kg and 100 mg/kg, intraperitoneal injection, three times a week for 5 weeks) exhibits remarkable anti-arthritic effects and protective activity against hematotoxicity[6].

Solvent & Solubility
H2O : 50 mg/mL (100.32 mM; Need ultrasonic)
DMSO : 5 mg/mL (10.03 mM; ultrasonic and warming and adjust pH to 5 with HCl and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
