Interpretive Summary: Drug metabolism is a biochemical process by which drugs and xenobiotics are chemically modified to metabolites, primarily by liver enzymes. Metabolites may sometimes affect cellular therapeutic or toxicological processes, therefore knowledge of metabolic processes is essential for understanding drug or chemical actions in cellular systems.1 However, low recovery of metabolites from biological matrices makes identification and study difficult. Conventional chemical synthesis of metabolites is difficult, time consuming and expensive, but is often necessary.2 Here we demonstrate, the in-vitro synthesis and structural elucidation of metabolites of flunixin, a non-steroidal anti-inflammatory agent, and dicoumarol, a fungal anticoagulant using LC-MS/MS.
