Guanosine Chemical Properties,Usage,Production
Description
Guanosine is a purine nucleoside, in which the guanine attached to the C1 carbon of a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Its phosphorylated derivatives include GMP (guanosine monophosphate), cGMP (cyclic guanosine monophosphate), GDP (guanosine diphosphate), and GTP (guanosine triphosphate). These guanosine derivatives are very important in various biochemical processes, such as synthesis of nucleic acids and proteins, photosynthesis, muscle contraction, and intracellular signal transduction.
Guanosine is thought to have neuroprotective properties. It can reduce neuroinflammation, oxidative stress, and excitotoxicity, as well as exerting trophic effects in neuronal and glial cells. It is shown to be protective in central nervous system diseases including ischemic stroke, Alzheimer’s disease, Parkinson’s disease, spinal cord injury, nociception, and depression. Guanosine is found to be associated with purine nucleoside phosphorylase (PNP) deficiency, which is an inborn error of metabolism.

Description
Guanosine is a purine nucleoside that is comprised of the purine base guanine attached to a ribose moiety. Mono-, di-, tri-, and cyclic monophosphorylated forms of guanosine (GMP, GDP, GTP, and cGMP, respectively) are essential for a variety of endogenous biochemical processes, such as signal transduction, metabolism, and RNA synthesis.
Chemical Properties
White, crystalline powder; odorless; mild saline taste. Very slightly soluble in cold water; soluble in boiling water, dilute mineral acids, hot acetic acid, and dilute bases; insoluble in alcohol, ether, chloroform, and benzene.
Uses
Guanosine is used as a constituent of nucleic acids. It is used in metallic paints, simulated pearls,plastics,cosmetics industry etc,. It has been also used in pharmacokinetics as a prodrug. Guanosine is used in cell culture applications as a precursor of GMP.
Uses
Guanosine has been used:
- as a reference standard for the analysis of glucosinolates by high-performance liquid chromatography with diode-array detection and electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI/MS)
- as a component of Mouse Embryonic Fibroblasts (MEFs) culture
- as a standard for the detection of residual RNA contaminant in oil palm plant genome samples by HPLC
Definition
A NUCLEOSIDE present in DNA and RNA and consisting of guanine linked to D-ribose via a β-glycosidic bond.
Definition
ChEBI: A purine nucleoside in which guanine is attached to ribofuranose via a beta-N9-glycosidic bond.
General Description
Guanosine is an aromatic organic molecule and a purine nucleoside. It is present in the cerebrospinal fluid, intestinal cells, blood-brain barrier and in brain microvessels.
Biochem/physiol Actions
Guanosine nucleoside elicits cellular effect as the guanine-based purinergic system. It modulates glutamate uptake by glutamate transporters. It may have neuroprotective functionality in central nervous system disorders. Guanosine promotes neurite arborization, outgrowth, proliferation and differentiation. Administration of guanosine replenished GTP and elicits protective function in renal ischemic injury.
Purification Methods
It crystallises from water as a dihydrate. Dry it at 110o.[Beilstein 26/18 V 81.]
