guanosine

Guanosine (DL-Guanosine) is a purine nucleoside formed from a beta-N9-glycosidic bond between guanine and a ribose ring, and is essential for metabolism.

Guanosine 5'-triphosphate trisodium salt (5'-GTP trisodium salt) activates signal-transducing G proteins involved in cellular processes such as proliferation, differentiation, and activation of intracellular kinase cascades. It regulates proliferation and apoptosis through the hydrolysis by small GTPases Ras and Rho, and plays a role in vesicle docking, fusion, and formation via Rab. Additionally, GTP serves as an energy-rich precursor for the biosynthesis of DNA and RNA.

GUANOSINE 3':5'-CYCLIC MONOPHOSPHATE SOD (cGMP sodium salt) , also known as cGMP, is a cellular regulatory agent and has been described as a second messenger. Its levels increase in response to a variety of hormones, including acetylcholine, insulin, and oxytocin. GUANOSINE 3':5'-CYCLIC MONOPHOSPHATE SOD activates protein kinase G (PKG) and modulates ion channel conductance, with signaling affecting diverse processes including smooth muscle relaxation and proliferation, phototransduction, and energy homeostasis.

Guanosine (DL-Guanosine) is a purine nucleoside formed from a beta-N9-glycosidic bond between guanine and a ribose ring and is essential for metabolism.

Nucleoside Derivatives –3'-Modified nucleoside

2'-Deoxyguanosine 5'-monophosphate disodium (5'-dGMP disodium) is a GTP derivative that serves as an oxidizable target and is used in forming polycomplexes with other compounds.

2'-Deoxyguanosine monohydrate (Guanine-2'-deoxyriboside) is a nucleoside consisting of the base guanine and the sugar deoxyribose. It is like guanosine, but with one oxygen atom removed. It is a nucleoside component of DNA. 2'-Deoxyguanosine monohydrate can be converted to 8-hydroxy-deoxyguanosine (8-OHdG) due to hydroxyl radical attack at the C8 of guanine. 8-OHdG is a sensitive marker of the DNA damage This damage, if left unrepaired, has been proposed to contribute to mutagenicity and cancer promotion.

8-Bromoguanosine is a brominated derivative of guanosine. It is activate lymphocytes through an intracellular mechanism to exert immunostimulatory effects.

N2-Methylguanosine is a modified nucleoside found at several specific sites in various tRNAs.

Iso-guanosine derivative

2'-Deoxyguanosine (Guanine deoxyriboside) is a purine nucleoside that is recognized by members of the 2'-dG-II family.2'-Deoxyguanosine has been associated with aging, mutation, and carcinogenesis, and is oxidized by molecular oxygen.

7-Methylguanosine is a novel cNIIIB nucleotidase inhibitor with an IC50 of 87.8 ± 7.5 μM.

1-Methylguanosine (N1-Methylguanosine) is a methylated nucleoside. It is known that some modified, especially methylated, nucleosides originating from RNA degradation are excreted in abnormal levels in the urine of patients with malignant tumors.

8-Hydroxy-2'-deoxyguanosine (8-OHdG) is a good biomarker for risk assessment of various cancers and degenerative diseases.

8-hydroxyguanosine (8-OHG) is a marker for measuring the rate of oxidative damage to nucleic acids and lipids.

N2,N2-Dimethylguanosine, a urinary nucleoside, exhibits significantly higher mean levels in patients with colorectal cancer compared to those with intestinal villous adenoma or healthy adults.

3-Methylxanthine, a xanthine derivative, is a cyclic guanosine monophosphate (GMP) inhibitor with an IC50 of 920 μM on guinea-pig isolated trachealis muscle. It inhibits xanthine crystallization and could protect patients with xanthinuria from developing renal xanthine calculi.

5'-Guanylic acid (5'-guanosine monophosphate) is implicated in several metabolic disorders, including the AICA-ribosiduria pathway, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (APRT), and the 2-hydroxyglutric aciduria pathway.

5'-Guanylic acid disodium salt (GMP-5) is a purine ribonucleoside monophosphate. L-Glutamic acid and guanosine monophosphate are biosynthesized from xanthylic acid and L-glutamine via GMP synthase [glutamine-hydrolyzing]. Guanosine triphosphate and guanosine monophosphate are biosynthesized from diguanosine tetraphosphate via bis(5'-nucleosyl)-tetraphosphatase [asymmetrical]. In humans, guanosine monophosphate is involved in the kanamycin, telithromycin, tobramycin, and erythromycin action pathways, and several metabolic disorders including AICA-ribosiduria, adenosine deaminase deficiency, adenine phosphoribosyltransferase deficiency (aprt), and 2-hydroxyglutric aciduria (D and L form) pathways. Guanosine monophosphate is also found in foods like onion-family vegetables, millet, Chinese water chestnut, and red rice, serving as a potential biomarker for the consumption of these foods.
