1198-47-6 - Nature
Open Data Verified Data
- This product is yellow crystalline powder; Odorless, slightly sweet taste. Slightly soluble in water and ethanol, practically insoluble in ether. Water of crystallization was lost at 140 °c. Soluble in alkaline aqueous solution, but very unstable, slow hydrolysis, light notes into black in the air. Soluble in boiling water. The melting point was 313-314 °c.
- This product is a purine antimetabolite, into the body into 6-mercaptopurine nucleotides, prevent inosinic acid into adenosine, xanthine nucleotides, inhibit the biosynthesis of Col. 6 A Mercaptopurine is hypoxanthine analogs, can competitively inhibit hypoxanthine into inosinic acid, prevent guanine into guanosine, so the inhibition of RNA and DNA synthesis, killing the proliferation of cells in each phase.
- oral absorption, 50% ~ 80% in the liver by xanthine oxidase oxidation to 6 a thiol uric acid. Its metabolites and part of the prototype are excreted by the urine. Long use has a certain accumulation, cancer cells are easy to produce drug resistance, but this drug-resistant cancer cells have increased sensitivity to methotrexate side sensitive phenomenon.

Open Data Verified Data
- gastrointestinal reaction was Nausea, Vomit, decreased appetite, sometimes Diarrhea, stomatitis and oral ulcer. Bone marrow suppression is more obvious, white blood cells, platelet reduction, and even reduce the whole blood. Hemogram should be strictly checked during medication. A small number of patients can appear liver function damage and yellow
- ↑, which could be recovered after drug withdrawal. Liver function tests should be performed during administration. Liver and kidney dysfunction should be reduced with caution. When combined with allopurinol, allopurinol should be reduced to 25% ~ 50% of the original dose,
- under shading, sealed and preserved.
