Protein acetylation

Protein acetylation are acetylation reactions that occur within living cells as drug metabolism, by enzymes in the liver and other organs. Pharmaceuticals frequently employ acetylation to enable such esters to cross the blood–brain barrier, where they are deacetylated by enzymes (carboxylesterases) in a manner similar to acetylcholine. Examples of acetylated pharmaceuticals are diacetylmorphine (heroin), acetylsalicylic acid (aspirin), THC-O-acetate, and diacerein. Conversely, drugs such as isoniazid are acetylated within the liver during drug metabolism. A drug that depends on such metabolic transformations in order to act is termed a prodrug.
