2-amino-6-mercaptopurine crystalline - Nature
Open Data Verified Data
- This product is light yellow crystalline powder; Odorless or almost odorless. Insoluble in water, ethanol or chloroform; Soluble in dilute sodium hydroxide solution.
- This product is purine Antimetabolite. After being converted into the corresponding nucleotides in vivo, it can inhibit the synthesis of purine nucleotides; Its metabolic pathway is similar to that of mercaptopurine, which is a kind of DNA base, it can be incorporated into a DNA molecule as a wrong base, thus affecting the synthesis and function of DNA. It mainly acts on S phase, is a cycle specific drug, and has cross resistance to mercaptopurine, but the toxicity is small. In vivo metabolic pathways are: after methylation to become 2-amino -6-thiopurine, after the amino group to become 2-hydroxy -6-mercaptopurine, part of the oxidation to thiouric acid form is excreted in the urine.
