Methotrexate disodium (Standard)

Methotrexate disodium (Standard) (Amethopterin disodium (Standard); CL14377 disodium (Standard); WR19039 disodium (Standard)) is the analytical standard of Methotrexate disodium (HY-14519A). This product is intended for research and analytical applications. 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.
