Adenosine(5') oligophospho-(5') guanosines and guanosine(5') oligophospho-(5') guanosines in human platelets. [PDF]
Journal of Clinical Investigation, 1998 We isolated and identified nucleoside(5') oligophospho-(5') nucleosides containing adenosine and guanosine (ApnG; n = 3-6) as well as diguanosine polyphosphates (GpnG; n = 3-6) in human platelets. For identification, UV spectrometry, matrix-assisted laser desorption/ionization, postsource decay matrix-assisted laser desorption/ionization mass ...

Antiparkinsonian Efficacy of Guanosine in Rodent Models of Movement Disorder
Frontiers in Pharmacology, 2017 Guanosine (GUO) is a guanine-based purine nucleoside with important trophic functions and promising neuroprotective properties. Although the neuroprotective effects of GUO have been corroborated in cellular models of Parkinson’s disease (PD), its ...

Synthetic (p)ppGpp analogue is an inhibitor of stringent response in mycobacteria [PDF]
, 2017 Bacteria elicit an adaptive response against hostile conditions such as starvation and other kinds of stresses. Their ability to survive such conditions depends, in part, on stringent response pathways.

Neuromodulatory Effects of Guanine-Based Purines in Health and Disease
Frontiers in Cellular Neuroscience, 2018 The function of guanine-based purines (GBPs) is mostly attributed to the intracellular modulation of heteromeric and monomeric G proteins. However, extracellular effects of guanine derivatives have also been recognized.

Cyclic nucleotide specificity of the activator and catalytic sites of a cGMP-stimulated cGMP phosphodiesterase from Dictyostelium discoideum [PDF]
, 1985 The cellular slime mold Dictyostelium discoideum has an intracellular phosphodiesterase which specifically hydrolyzes cGMP. The enzyme is activated by low cGMP concentrations, and is involved in the reduction of chemoattractant-mediated elevations of ...

Antibiotics, 2021 Bacterial quorum sensing (QS) system regulates pathogenesis, virulence, and biofilm formation, and together they contribute to nosocomial infections. Opportunistic pathogens, such as Pseudomonas aeruginosa, rely on QS for regulating virulence factors ...

Dynamics of Microtubule Growth and Catastrophe [PDF]
, 2007 We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii ...

Guanosine Protects Neuronal PC12 Cells from Serum Deprivation-induced Cell Death
Pteridines, 2012 Survival of neurons is dependent on the presence of trophic and non-trophic factors. Previous findings showed that purine nucleosides have the potential to rescue cells from hypoxia-induced cell death. Here we demonstrate that purine nucleoside guanosine
