Purine nucleoside phosphorylase: A new marker for free oxygen radical injury to the endothelial cell [PDF]

, 1990
The effect of ischemia and reperfusion on purine nucleoside phosphorylase was studied in an isolated perfused rat liver model. This enzyme is localized primarily in the cytoplasm of the endothelial and Kupffer cells; some activity is associated with the ...

Crystal structure of the nucleoside 2′-deoxyguanosine dimethyl sulfoxide disolvate

Acta Crystallographica Section E: Crystallographic Communications, 2023
The title compound, C10H13N5O4·2C2H6OS, which is of interest with respect to its biological activity, at 183 K has orthorhombic (P212121) crystal symmetry. The structure displays a network of intermolecular N—H...N, N—H...O and O—H...O hydrogen bonds. 2′-

Magnetic circular dichroism within the Algebraic Diagrammatic Construction scheme of the polarisation propagator up to third order [PDF]

, 2022
We present an implementation of the B term of Magnetic Circular Dichroism within the Algebraic Diagrammatic Construction (ADC) scheme of the polarization propagator and its Intermediate State Representation. As illustrative results, the MCD spectra of the ADC variants ADC(2), ADC(2)-x and ADC(3) of the molecular systems uracil, 2-thiouracil, 4 ...

Ischemic preconditioning attenuates portal venous plasma concentrations of purines following warm liver ischemia in man [PDF]

, 2005
Background/Aims: Degradation of adenine nucleotides to adenosine has been suggested to play a critical role in ischemic preconditioning (IPC). Thus, we questioned in patients undergoing partial hepatectomy whether (i) IPC will increase plasma purine ...

A Generalization of the Auslander-Reiten Conjecture for the Bounded Derived Category [PDF]

Archiv der Mathematik: Volume 98, Issue 6 (2012), Page 507-511, 2011
We study the bounded derived category $\D^b(\Rmod)$ of a left Noetherian ring $R$. We give a version of the Generalized Auslander-Reiten Conjecture for $\D^b(\Rmod)$ that is equivalent to the classical statement for the module category and is preserved under derived equivalence.

Azathioprine and 6-mercaptopurine for maintenance of surgically-induced remission in Crohn’s disease [PDF]

, 2014
Background Crohn’s disease (CD) is a chronic relapsing inflammatory condition. Many patients fail to achieve remission with medical management and require surgical interventions.

Efficient Biocatalytic Synthesis of Dihalogenated Purine Nucleoside Analogues Applying Thermodynamic Calculations [PDF]

, 2020
The enzymatic synthesis of nucleoside analogues has been shown to be a sustainable and efficient alternative to chemical synthesis routes. In this study, dihalogenated nucleoside analogues were produced by thermostable nucleoside phosphorylases in ...

Potential Mechanisms Connecting Purine Metabolism and Cancer Therapy

Frontiers in Immunology, 2018
Unrestricted cell proliferation is a hallmark of cancer. Purines are basic components of nucleotides in cell proliferation, thus impaired purine metabolism is associated with the progression of cancer.

Metabolic engineering of the purine biosynthetic pathway in Corynebacterium glutamicum results in increased intracellular pool sizes of IMP and hypoxanthine [PDF]

, 2012
Background: Purine nucleotides exhibit various functions in cellular metabolism. Besides serving as building blocks for nucleic acid synthesis, they participate in signaling pathways and energy metabolism.

The dynamics of single spike-evoked adenosine release in the cerebellum [PDF]

, 2010
The purine adenosine is a potent neuromodulator in the brain, with roles in a number of diverse physiological and pathological processes. Modulators such as adenosine are difficult to study as once released they have a diffuse action (which can affect ...
