[13C6]-Diflunisal is a stable isotope-labeled compound that is commonly used in pharmacokinetic studies. It is a non-steroidal anti-inflammatory drug (NSAID) that is used to relieve pain and inflammation caused by conditions such as arthritis and osteoarthritis. The compound is labeled with 13 carbon atoms, which are stable isotopes of carbon, making it useful in metabolic studies.
The chemical formula for [13C6]-Diflunisal is C17H10D6F2O3, with a molecular weight of 350.34 g/mol. The compound is a white or off-white crystalline powder that is slightly soluble in water and soluble in organic solvents like ethanol and methanol. It is administered orally in tablet form, with a recommended dosage of 500mg every 12 hours.
The pharmacological action of [13C6]-Diflunisal is similar to other NSAIDs, as it inhibits the activity of cyclooxygenase (COX), an enzyme that is responsible for the production of prostaglandins. By inhibiting COX, [13C6]-Diflunisal reduces inflammation and pain. The compound is metabolized in the liver by cytochrome P450 enzymes, and its metabolites are eliminated primarily through urine.
In summary, [13C6]-Diflunisal is a stable isotope-labeled compound that is commonly used in pharmacokinetic studies. Its chemical formula, pharmacological action, and metabolism make it an important tool in the study of NSAIDs and their effects on the body.
