Abstract
Thiopurines are antimetabolite prodrugs used clinically as antineoplastics and as immunosuppressants. The first clinically effective thiopurines, thioguanine and mercaptopurine, were developed in the 1950s by Wellcome Research Laboratory scientists Gertrude Elion and George Hitchings [1]. After the approval of mercaptopurine in 1953 by FDA for the treatment of leukemia, it was discovered that when it was combined with other anticancer agents, childhood leukemia could be cured. The development of these compounds contributed to Elion and Hitchings being awarded the Nobel Prize in medicine in 1988. Today, there are three thiopurine drugs (mercaptopurine, thioguanine, and azathioprine) (Fig. 7.) that are widely used in the treatment of leukemia, rheumatic diseases, inflammatory bowel disease, and solid organ transplant.
