History of aspirin Hermann Hildebrandt). In 1894, the young chemist Felix Hoffmann joined the pharmaceutical group. Dreser, Eichengrün and Hoffmann would be the key figures in the development of acetylsalicylic acid as the drug Aspirin (though their respective roles have been the subject of some contention). In 1897, Hoffmann started working to find a less irritating substitute for salicylic acid. It is generally accepted that he turned to this idea because his father was suffering the side effects of taking sodium salicylate for rheumatism. In 1853, Charles Frédéric Gerhardt had published the first methods to prepare acetylsalicylic acid. In the course of his
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
