Copper aspirinate use of copper aspirinate as a pigment in PVC and Polystyrene has also been investigated. Copper aspirinate Copper(II) aspirinate is an aspirin chelate of copper(II) cations (Cu). It is used to treat rheumatoid arthritis. Copper aspirinate can be prepared by several methods. In one route of preparation, an excess of acetylsalicylic acid is dissolved in aqueous sodium carbonate. Sodium hydroxide is not suitable for this purpose, because it will hydrolyse acetylsalicylic acid ("ASA") into salicylic acid and sodium acetate. The resulting solution is then filtered to remove any undissolved acetylsalicylic acid and is mixed with a solution containing Cu cations
Mycophenolic acid Mycophenolic acid Mycophenolic acid, also called mycophenolate, is an immunosuppressant drug used to prevent rejection in organ transplantation. It was initially marketed as the prodrug mycophenolate mofetil (MMF) to improve oral bioavailability. More recently, the salt mycophenolate sodium has also been introduced. Mycophenolate mofetil is marketed under the trade name CellCept and mycophenolate sodium as Myfortic. Discovered by an Italian medical scientist Bartolomeo Gosio in 1893, mycophenolic acid was the first antibiotic to be synthesised in pure and crystalline form. But its medical application was forgotten until two American scientists C.L. Alsberg and O.M. Black resynthesised it in 1912, and
