This product is intended for research and analytical applications. Methotrexate (Amethopterin; CL14377; WR19039) is an orally active antifolate (Antifolate). Methotrexate inhibits dihydrofolate reductase (DHFR), blocks tetrahydrofolate production, suppresses purine/pyrimidine synthesis and transmethylation, and causes intracellular accumulation of AICAR. Methotrexate promotes extracellular adenosine release, regulates the cytokine network, and inhibits the alarmin function of HMGB1. Methotrexate induces apoptosis and cytotoxicity, upregulates the expression of iNOS and COX-2, suppresses hippocampal neurogenesis, and induces pulmonary fibrosis. Methotrexate 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.

Betaine also acts as an osmolyte, to maintain the avian’s cellular water and ion balance to improve the avian’s capacity against heat stress via preventing dehydration and osmotic inactivation. It helps in maintaining the protective osmolytic activity, especially in heat-stressed birds. Betaine may promote various intestinal microbes against osmotic variations and thus improve microbial fermentation activity.
