Landscape of targets within nucleoside metabolism for the modification of immune responses [PDF]
Frontiers in OncologyNucleoside metabolism regulates immune cell development and function, but the therapeutic implications of this link have yet to be fully realized. Evidence for the importance of nucleoside metabolism in immune system control was provided by observations ...

Thermodynamic reaction control of nucleoside phosphorolysis [PDF]
, 2020 Nucleoside analogs represent a class of important drugs for cancer and antiviral treatments. Nucleoside phosphorylases (NPases) catalyze the phosphorolysis of nucleosides and are widely employed for the synthesis of pentose‐1‐phosphates and nucleoside ...

Conical intersection dynamics of pyrimidine nucleosides tracked with sub-20-fs UV pulses [PDF]
EPJ Web of Conferences, 2019 By combining transient absorption spectroscopy with sub-20-fs UV pulses and ab initio numerical simulations we follow the ultrafast dynamics in pyrimidine nucleosides and visualize the passage through conical intersections presiding excited state ...

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 ...

Re-Discovery of Pyrimidine Salvage as Target in Cancer Therapy
Cells, 2022 Nucleotides are synthesized through two distinct pathways: de novo synthesis and nucleoside salvage. Whereas the de novo pathway synthesizes nucleotides from amino acids and glucose, the salvage pathway recovers nucleosides or bases formed during DNA or ...

Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria [PDF]
, 1975 Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was

Synthesis and Biological Activity of Reversed Pyrimidine Nucleosides
Croatica Chemica Acta, 2015 An efficient approach to reversed nucleosides which enables their synthesis in gram quantities is described. N-1′-Pyrimidine reversed nucleosides were prepared by treating of the sodium salt of pyrimidine bases with protected 5-tosyl ribose ...
