Azathioprine
An immunosuppressant created in the late 1950s by Gertrude Elion and George Hitchings, Nobel laureates in medicine in 1988: it helps prevent transplant rejection and is used in autoimmune diseases such as rheumatoid arthritis. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards, nitrosamines and other impurities.
Did you know?It was born as a masked form of 6-mercaptopurine, intended against cancer: British surgeon Roy Calne tested it in transplants, and in 1962 it made possible the first successful kidney transplant between unrelated people.
