L(+)-Amethopterin hydrate is an immunosuppressant that suppresses the immune system by inhibiting RNA synthesis. It is a structural analogue of folic acid and has been shown to be effective in treating autoimmune diseases, such as rheumatoid arthritis. L(+)-Amethopterin hydrate is a neutral compound that is soluble in water and microsomal membranes, making it more easily absorbed through the gut than other compounds of this class. It also has been shown to have no toxic effects on cardiac cells at therapeutic concentrations. These properties make L(+)-Amethopterin hydrate an attractive candidate for treating autoimmune diseases when other treatments have failed.
