155960-91-1 Usage
General Description
Ethyl 3,4-dihydro-4-oxoquinazoline-6-carboxylate, also known as methotrexate, is a powerful and widely used medication for the treatment of cancer and autoimmune diseases. It works by inhibiting the enzyme dihydrofolate reductase, which is involved in the synthesis of DNA, RNA, and proteins. By doing so, it impairs the growth of cancer cells and suppresses the immune response in autoimmune conditions. Methotrexate is typically taken orally or injected and is known to have both anti-inflammatory and immunosuppressive properties. It is a highly regulated and potent medication that can have significant side effects and requires careful monitoring by healthcare professionals.
