Phosphoribosyl pyrophosphate
Phosphoribosyl pyrophosphate, also known as PRPP or PRib-PP, belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. Phosphoribosyl pyrophosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). Phosphoribosyl pyrophosphate exists in all living species, ranging from bacteria to humans. Within humans, phosphoribosyl pyrophosphate participates in a number of enzymatic reactions. In particular, guanine and phosphoribosyl pyrophosphate can be biosynthesized from guanosine monophosphate through its interaction with the enzyme adenine phosphoribosyltransferase. In addition, guanine and phosphoribosyl pyrophosphate can be biosynthesized from guanosine monophosphate; which is catalyzed by the enzyme hypoxanthine-guanine phosphoribosyltransferase. In humans, phosphoribosyl pyrophosphate is involved in adenosine deaminase deficiency. Phosphoribosyl pyrophosphate is a pentosephosphate and it is the key substance in the biosynthesis of histidine, tryptophan, and purine and pyrimidine nucleotides. It is formed from ribose 5-phosphate by the enzyme ribose-phosphate diphosphokinase. It plays a role in transferring phosphate groups in several reactions. Phosphoribosyl pyrophosphate (PRPP) is a pentosephosphate. The key substance in the biosynthesis of histidine, tryptophan, and purine and pyrimidine nucleotides.

Thioguanine
Thioguanine is only found in individuals that have used or taken this drug. It is an antineoplastic compound which also has antimetabolite action. The drug is used in the therapy of acute leukemia. [PubChem]Thioguanine competes with hypoxanthine and guanine for the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) and is itself converted to 6-thioguanilyic acid (TGMP), which reaches high intracellular concentrations at therapeutic doses. TGMP interferes with the synthesis of guanine nucleotides by its inhibition of purine biosynthesis by pseudofeedback inhibition of glutamine-5-phosphoribosylpyrophosphate amidotransferase, the first enzyme unique to the de novo pathway of purine ribonucleotide synthesis. TGMP also inhibits the conversion of inosinic acid (IMP) to xanthylic acid (XMP) by competition for the enzyme IMP dehydrogenase. Thioguanine nucleotides are incorporated into both the DNA and the RNA by phosphodiester linkages, and some studies have shown that incorporation of such false bases contributes to the cytotoxicity of thioguanine. Its tumor inhibitory properties may be due to one or more of its effects on feedback inhibition of de novo purine synthesis; inhibition of purine nucleotide interconversions; or incorporation into the DNA and RNA. The overall result of its action is a sequential blockade of the utilization and synthesis of the purine nucleotides.

Diphosphate
In chemistry, the anion, the salts, and the esters of pyrophosphoric acid are called pyrophosphates. The anion is abbreviated PPi and is formed by the hydrolysis of ATP into AMP in cells. This hydrolysis is called pyrophosphorolysis. The pyrophosphate anion has the structure P2O74-, and is an acid anhydride of phosphate. It is unstable in aqueous solution and rapidly hydrolyzes into inorganic phosphate. Pyrophosphate. CAS Common Chemistry.
