Mercaptopurine (6-MP), sold under the brand name Purinethol among others, is a medication used for cancer and autoimmune diseases. [2] Specifically it is used to treat acute lymphocytic leukemia (ALL), acute promyelocytic leukemia (APL), Crohn's disease, and ulcerative colitis. [2] [3] For acute lymphocytic leukemia it is generally used with ...
Thiopurine drugs such as 6-mercaptopurine are used as chemotherapeutic agents and immunosuppressive drugs. Genetic polymorphisms that affect this enzyme's activity are correlated with variations in sensitivity and toxicity to such drugs. About 1/300 individual is deficient for the enzyme. [5]
Anti-metabolites masquerade as a purine (azathioprine, mercaptopurine) or a pyrimidine, chemicals that become the building-blocks of DNA. They prevent these substances from becoming incorporated into DNA during the S phase (of the cell cycle), stopping normal development and cell division. [6] Anti-metabolites also affect RNA synthesis.
Thioguanine Mercaptopurine Azathioprine. The thiopurine drugs are purine antimetabolites widely used in the treatment of acute lymphoblastic leukemia, autoimmune disorders (e.g., Crohn's disease, rheumatoid arthritis), and organ transplant recipients. Metabolism is catalyzed by S-methyltransferase and nudix hydrolase 15 (NUDT15). [1]
Azathioprine and 6-MP may be useful for the following indications: Maintenance therapy with azathioprine or 6-mercaptopurine may lead people with active Crohn's to take less steroid medication. This may lower side effects related to steroid treatments. [9] Fistulizing disease [11] Maintenance of remission after surgery for Crohn's disease [12]
Salk Institute researchers have identified a key protein that may help users of GLP-1 drugs such as Ozempic and Wegovy maintain muscle mass while losing weight.

A prodrug, it is widely used in transplantation to control rejection reactions. It is nonenzymatically cleaved to mercaptopurine , a purine analogue that inhibits DNA synthesis. By preventing the clonal expansion of lymphocytes in the induction phase of the immune response, it affects both cell immunity and humoral immunity .
