  • Chemische Eigenschaften very slightly yellow to cream crystalline powder
  • Verwenden Organic synthesis, metabolism, and biochemi- cal research. (2) One of a number of basic compounds found in living matter and having a purine-type molecular structure.
  • Definition A simple nitrogenous organic molecule with a double ring structure. Members of the purine group include adenine and guanine, which are constituents of the nucleic acids, and certain plant alkaloids, such as caffeine and theobromine.
  • Definition purine: An organic nitrogenous base(see formula), sparingly soluble inwater, that gives rise to a group ofbiologically important derivatives,notably adenine and guanine,which occur in nucleotides and nucleicacids (DNA and RNA).
  • Definition ChEBI: The 9H-tautomer of purine.
  • Enzyminhibitor This heterocyclic base (FW = 120.11 g/mol; CAS 120-73-0) is the structural foundation for a wide variety of naturally occurring compounds. It is soluble in water and absorbs light in the ultraviolet. Purine was first synthesized, characterized, and named in the late nineteenth century by Emil Fischer, the 1902 Nobel Laureate in Chemistry. Target (s) : adenine deaminase; adenosine deaminase; 5-phosphoribosylamine synthetase, or ribose-5-phosphate:ammonia ligase; xanthine dehydrogenase, weakly inhibited; xanthine oxidase; and xanthine phosphoribosyltransferase.
  • läuterung methode It crystallises from toluene or EtOH, and sublimes at 100-150o/0.1mm or 160o/10-4mm. The picrate has m 207-209o after crystallisation from 20volumes of H2O. [Beilstein 26 H 354, 26 III/IV 1736.]
