purine

Purine (7H-Imidazo(4,5-d)pyrimidine) is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Two of the bases in nucleic acids, adenine and guanine, are purines. Purines from food (or from tissue turnover) are metabolised by several enzymes, including xanthine oxidase, into uric acid. High levels of uric acid can predispose to gout when the acid crystalises in joints; this phenomenon only happens in humans and some animal species (e.g. dogs) that lack an intrinsic uricase enzyme that can further degrade uric acid.

Hypoxanthine (Purin-6-ol), also known as purine-6-ol or Hyp. Hypoxanthine is a naturally occurring purine derivative and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the nucleotide salvage pathway. Under normal circumstances hypoxanthine is readily converted to uric acid.hypoxanthine is first oxidized to xanthine, which is further oxidized to uric acid by xanthine oxidase.

PI-55 (6-(2-hydroxy-3-methylbenzylamino)purine) is a cytokinin receptor inhibitor that exhibits structural similarity to 6-benzylaminopurine (BAP). It competitively inhibits BAP binding on the specific Arabidopsis receptors CRE1/AHK4 and AHK3. Furthermore, PI-55 effectively suppresses cytokinins-induced haustorium formation and enhances parasite aggressiveness [1].

Nebularine (9-(beta-D-Ribofuranosyl)-9H-purine) is a purine nucleoside analog with a broad spectrum of antitumor activity, targeting inert lymphoid malignancies and inducing apoptosis.The anticancer mechanism of Nebularine is dependent on the inhibition of DNA synthesis.
