Purine is a heterocyclic aromatic organic compound that consists of two rings (pyrimidine and imidazole) fused together. It is water-soluble. Purine also gives its name to the wider class of molecules, purines, which include substituted purines and their tautomers. They are the most widely occurring nitrogen-containing heterocycles in nature. [1]
[1] [2] At high levels, uric acid crystallizes and the crystals deposit in joints, tendons, and surrounding tissues, resulting in an attack of gout. [1] Gout occurs more commonly in those who regularly drink beer or sugar-sweetened beverages; eat foods that are high in purines such as liver, shellfish, or anchovies; or are overweight.

Hyperuricemia (high levels of uric acid), which induces gout, has various potential origins: Diet may be a factor. High intake of dietary purine, high-fructose corn syrup, and sucrose can increase levels of uric acid. [36] [37] Serum uric acid can be elevated by reduced excretion via the kidneys. [38]
The structure is a purine alkylated with an oxidized sugar fragment. Eritadenine synthesis: [2] Alternative synthesis: [3] Ring opening of the protected lactone (1), derived from erythrose with sodium phthalimide gives the acid 2; hydrazinolysis (cf Gabriel synthesis) then leads to the amino acid 3.
