Hybridization Properties of RNA Containing 8-Methoxyguanosine and 8-Benzyloxyguanosine. [PDF]

open access: yesPLoS ONE, 2015
Modified nucleobase analogues can serve as powerful tools for changing physicochemical and biological properties of DNA or RNA. Guanosine derivatives containing bulky substituents at 8 position are known to adopt syn conformation of N-glycoside bond.

Photoactivation of trans diamine platinum complexes in aqueous solution and effect on reactivity towards nucleotides [PDF]

open access: yes, 2010
We show that UVA irradiation (365 nm) of the Pt-IV complex trans,trans,trans-[(PtCl2)-Cl-IV(OH)(2)(dimethylamine) (isopropylamine)] (1), induces reduction to Pt-II photoproducts.

Dietary nitrate enhances the contractile properties of human skeletal muscle [PDF]

open access: yes, 2018
Dietary nitrate, a source of nitric oxide (NO), improves the contractile properties of human muscle. We present the hypothesis that this is due to nitrosylation of the ryanodine receptor and increased NO signaling via the soluble guanyl cyclase-cyclic ...

Optimization of guanosine-based hydrogels with boric acid derivatives for enhanced long-term stability and cell survival

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Tissue defects can lead to serious health problems and often require grafts or transplants to repair damaged soft tissues. However, these procedures can be complex and may not always be feasible due to a lack of available tissue.

Covalent Guanosine Mimetic Inhibitors of G12C KRAS.

open access: yesACS Medicinal Chemistry Letters, 2017
Ras proteins are members of a large family of GTPase enzymes that are commonly mutated in cancer where they act as dominant oncogenes. We previously developed an irreversible guanosine-derived inhibitor, SML-8-73-1, of mutant G12C RAS that forms a ...

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

open access: yes, 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.

A guanosine 5′-triphosphate-dependent protein kinase is localized in the outer envelope membrane of pea chloroplasts [PDF]

open access: yes, 1988
A guanosine 5-triphosphate (GTP)-dependent protein kinase was detected in preparations of outer chloroplast envelope membranes of pea (Pisum sativum L.) chloroplasts.

Current Modulation of Guanylate Cyclase Pathway Activity—Mechanism and Clinical Implications

open access: yesMolecules, 2021
For years, guanylate cyclase seemed to be homogenic and tissue nonspecific enzyme; however, in the last few years, in light of preclinical and clinical trials, it became an interesting target for pharmacological intervention.

In Search of Enzymes with a Role in 3′, 5′-Cyclic Guanosine Monophosphate Metabolism in Plants

open access: yesFrontiers in Plant Science, 2016
In plants, nitric oxide (NO)-mediated 3′, 5′-cyclic guanosine monophosphate (cGMP) synthesis plays an important role during pathogenic stress response, stomata closure upon osmotic stress, the development of adventitious roots and transcript regulation ...

Liberators of NO exert a dual effect on renin secretion from isolated mouse renal juxtaglomerular cells [PDF]

open access: yes, 1993
This study aimed to examine the role of nitric oxide (NO) in the regulation of renin secretion from renal juxtaglomerular (JG) cells. Using primary cultures of mouse renal JG cells, we found that sodium nitroprusside (SNP) and 3-morpholino-sydnonimin ...
