4-Methylamino antipyrine-d3

4-Methylamino antipyrine-d3 is a deuterated analog of 4-methylaminoantipyrine, a non-steroidal anti-inflammatory drug (NSAID) with antipyretic and analgesic properties. It is commonly used in the treatment of pain and fever, as well as in the management of inflammatory conditions such as rheumatoid arthritis and osteoarthritis. The chemical formula of 4-methylamino antipyrine-d3 is C12H10D3N3O, and it has a molecular weight of 221.27 g/mol. The deuterated version of this compound is used in research and drug development studies as a stable isotopic internal standard in mass spectrometry analysis. The mechanism of action of 4-methylamino antipyrine-d3 is not fully understood, but it is believed to inhibit cyclooxygenase enzymes, which are responsible for the production of prostaglandins that cause inflammation and pain. By blocking these enzymes, the drug reduces the levels of prostaglandins in the body, leading to a reduction in pain and inflammation. 4-Methylamino antipyrine-d3 is typically administered orally, and its effects last for several hours. It is metabolized in the liver and excreted in the urine. The drug is generally well-tolerated, but like all NSAIDs, it can cause side effects such as gastrointestinal irritation, renal impairment, and bleeding disorders. Therefore, it is important to use this drug under medical supervision and follow the recommended dosage instructions.
