Isotope exchange between hypoxanthine and both inosinate and guanylate, and between guanine and the same two ribonucleotides, support the view that hypoxanthine and guanine bind to the same site on hypoxanthine-guanine phosphoribosyltransferase.

Synthesis of hypoxanthin from xanthin
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1969We have described a preparative method for producing hypoxanthin by heating xanthin with a mixture of formamide and benzylamine.

Purine metabolism in the central nervous system (CNS) is characterized by: (i) reduced de novo purine synthesis (1), (ii) increased HPRT activity (2), and (iii) absence of detectable xanthine oxidase activity (3, 4). These facts determine that, instead of uric acid, the end products of purine nucleotide degradation in the CNS are hypoxanthine for ...

Hypoxanthine Uptake by Isolated Brain Microvessels
1986Brain is among the most active tissues in nucleotide and nucleic acid synthesis (1) but the role of the blood brain barrier in regulating the transport of purine and pyrimidine has not, so far, well defined. The existence of a presynaptic purinergic modulation of trasmitter release in the central nervous system (1) emphasize a possibly important role ...

Gas phase studies of hypoxanthine
2010Hypoxanthine is not only a naturally occurring nucleobase in tRNA but also a damaged one in DNA arising from oxidative deamination of adenine. This thesis describes studies of the intrinsic reactivity of hypoxanthine as a free base and the stability of DNA duplexes containing hypoxanthine in the gas phase versus in solution by calculation and mass ...
