Targeting purine metabolism in ovarian cancer
Purine, an abundant substrate in organisms, is a critical raw material for cell proliferation and an important factor for immune regulation. The purine de novo pathway and salvage pathway are tightly regulated by multiple enzymes, and dysfunction in ...

Trypanosoma brucei methylthioadenosine phosphorylase protects the parasite from the antitrypanosomal effect of deoxyadenosine [PDF]
Trypanosoma brucei causes African sleeping sickness for which no vaccine exists and available treatments are of limited use due to their high toxicity or lack of efficacy. T.

Pyrimidine biosynthesis is not an essential function for trypanosoma brucei bloodstream forms [PDF]
<p>Background: African trypanosomes are capable of both pyrimidine biosynthesis and salvage of preformed pyrimidines from the host, but it is unknown whether either process is essential to the parasite.</p> <p>Methodology/Principal ...

Pyrazolo[4,3-e][1,2,4]triazines: Purine Analogues with Electronic Absorption in the Visible Region
Synthesis of several pryrazolo[4,3-e][1,2,4]-triazines is described. Theabsorption spectrum of some 5-substituted derivatives was found to extend to the visibleregion.

Functional and genetic evidence that nucleoside transport is highly conserved in Leishmania species: Implications for pyrimidine-based chemotherapy [PDF]
Leishmania pyrimidine salvage is replete with opportunities for therapeutic intervention with enzyme inhibitors or antimetabolites. Their uptake into cells depends upon specific transporters; therefore it is essential to establish whether various ...

Cerebellar abnormalities in purine nucleoside phosphorylase deficient mice
Inherited defects in purine nucleoside phosphorylase (PNP) cause severe T cell immunodeficiency and progressive neurological dysfunction, yet little is known about the effects of PNP deficiency on the brain.

Plasmodium falciparum parasites are killed by a transition state analogue of purine nucleoside phosphorylase in a primate animal model. [PDF]
Plasmodium falciparum causes most of the one million annual deaths from malaria. Drug resistance is widespread and novel agents against new targets are needed to support combination-therapy approaches promoted by the World Health Organization. Plasmodium

Ethenoguanines undergo glycosylation by nucleoside 2'-deoxyribosyltransferases at non-natural sites. [PDF]
Deoxyribosyl transferases and functionally related purine nucleoside phosphorylases are used extensively for synthesis of non-natural deoxynucleosides as pharmaceuticals or standards for characterizing and quantitating DNA adducts.

Anatomical Distribution of Nucleoside System in the Human Brain and Implications for Therapy [PDF]
Nucleosides have a wide range of physiological and pathophysiological roles in the human brain as modulators of a variety of neural functions. For example, adenosine, inosine, guanosine, and uridine participate in the mechanisms underlying memory ...

Energy metabolism during the maturation of reticulocyte in vitro [PDF]
1. For the purpose to clarify the mechanism of the revolutional changes in energy metabolism during the reticulocyte maturation the metabolisms of glucose and of the pentose moieties of acid soluble nucleotides have been observed on rabbit reticulocytes ...
