Abstract The inherited disorders of purine metabolism associated with renal disease are listed in Table 24.1. They are the sole cause of only a small proportion of all renal disease and are therefore best considered as part of the overall problem of purine, especially uric acid metabolism-related renal disease.

3 Purine, Purine Nucleoside, and Purine Nucleotide Aminohydrolases
1971Publisher Summary This chapter discusses the chemical significance of adenosine aminohydrolase, 5′-adenylic acid aminohydrolase, adenine nucleoside, nucleotide aminohydrolase, guanine aminohydrolase, and guanosine aminohydrolase. The partially purified adenine aminohydrolase from Azotobacter vinelandii catalyzes the anaerobic conversion of adenine ...

Epilepsia, 1986
Summary: Developing antiepileptic agents that are specifically tailored to a patient's individual biochemistry has long been a goal of neurology. Three patients who had hyperuricosuria combined with a seizure disorder that failed to respond to traditional anticonvulsants are described. The patients had the best control of their seizure disorder when a

Feedback Control of Purine Biosynthesis by Purine Ribonucleotides
Nature, 1959IN recent years a number of biosynthetic sequences have been shown to be regulated by feedback mechanisms, which have been of two general types, the first involving regulation of the activity of an enzyme by an inhibitory effect of an end-product1,2, the second involving regulation of the rate of synthesis of an enzyme by negative-induction, or ...

Theoretical studies on the purine radical induced purine–purine type intrastrand cross-links
Organic & Biomolecular Chemistry, 2019Purine-type radicals can attack their 3′/5′ flanking purine deoxynucleosides forming the purine–purine type DNA intrastrand cross-links.

The fact that purine nucleotides and nucleosides are so important in normal cellular functions makes their analysis complicated. In order to measure tissue levels, samples have to be very rapidly fixed. Measurement in blood is complicated by the risk of releasing purine nucleotides during the sampling procedure and by the possibility of very rapid ...

The activation of adenosine A1, A2 andA3 receptors can protect neurones against damage generated by mechanical or hypoxic/ischaemic insults as well as excitotoxins. A1 receptors are probably effective by suppressing transmitter release and producing neuronal hyperpolarisation.
