| 应用领域 | Uses: MEDICATION、MEDICATION (VET)、Mercaptopurine tablets are indicated for maintenance therapy of acute lymphatic (lymphocytic、lymophoblastic) leukemia as part of a combination regimen. The response to this agent depends upon the particular subclassification of acute lymphatic leukemia and the age of the patient (pediatric or adult). Mercaptopurine is not effective prophylaxis or treatment of central nervous system leukemia. Mercaptopurine is not effective in acute myelogenous leukemia、chronic lymphatic leukemia、the lymphomas (including Hodgkins Disease)、or solid tumors.、Included in US product label、MEDICATION (VET): Rarely used in veterinary medicine. Veterinary uses of mercaptopurine have included adjunctive therapy of lymphosarcoma、acute leukemias、and severe rheumatoid arthritis. It may have potential benefit in treating other autoimmune conditions (eg、unresponsive ulcerative colitis) as well.、Antimetabolites、Antineoplastic、Immunosuppressive Agents、Nucleic Acid Synthesis Inhibitors、Methods of Manufacturing: In the original and most simple synthesis、hypoxanthine is heated with an excess of phosphorous pentasulfide for several hours at 200 °C in、e.g.、tetralin as the solvent.、Preparation from 7-aminothiazolo[5、4-d]pyrimidine: G. H. Hitchings、G. B. Elion、United States of America patent 2721866 (1955 to Burroughs Wellcome).、6-Chloropurine + sodium thiocyanate (dehydrochlorination) thiocyanate hydrolysis、Formulations、Preparations: Table: Mercaptopurine Preparations [Table#4501] |
