Oxidation potentials of guanine, guanosine and guanosine-5′-monophosphate: Theory and experiment

Electrochimica Acta, 2019
Abstract Guanine, having lower one-electron oxidation potential than other nucleobases, is of relevance to oxidative degradation of nucleic acids in mutagenesis, carcinogenesis, and aging. Here we compare oxidation potentials of guanine (G), guanosine (Guo), deoxyguanosine (dGuo), guanosine -5′- monophosphate (GMP) and 2′- deoxyguanosine -5 ...

Reactions of formaldehyde with guanosine

Toxicology Letters, 1981
Formaldehyde reacted with guanosine and the products were assayed using fluorescence spectroscopy at different pHs. The reaction products were fluorescent in alkali only as was found with commercial N-2 methylguanosine. Thus, formaldehyde appeared to react with N-2 of guanosine. The reaction was completed with 30s both at 0 degrees C or at 21 degrees C.

Neurotrophic Effects of Extracellular Guanosine

Nucleosides, Nucleotides and Nucleic Acids, 2008
Central nervous system (CNS) astrocytes release guanosine extracellularly, that exerts trophic effects. In CNS, extracellular guanosine (GUO) stimulates mitosis, synthesis of trophic factors, and cell differentiation, including neuritogenesis, is neuroprotective, and reduces apoptosis due to several stimuli.

Metabolism of Guanosine in Human Erythrocytes

Vox Sanguinis, 1985
Abstract. The metabolism of guanosine in human erythrocytes has been studied in two different experimental systems – direct incubation and dialysis incubation – the latter allowing continuous addition and removal of substances. Intra‐ and extracellular purine compounds were analyzed using high‐performance liquid chromatography (HPLC).

Inactivation of phosphoenolpyruvate carboxykinase by the guanosine nucleotide analogue, 5′-p-fluorosulfonylbenzoyl guanosine

Biochemical and Biophysical Research Communications, 1981
Abstract Rat liver cytosolic phosphoenolpyruvate carboxykinase is inactivated by incubation with 0.84 mM 5′-p-fluorosulfonylbenzoyl guanosine, but is not appreciably affected by the adenosine analogue, 5′-p-fluorosulfonylbenzoyl adenosine, in correspondance with the known nucleotide specificity of this enzyme.
