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. |

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 |
A constituent of nucleic acids. |
Definition |
A NUCLEOSIDE present in DNA and RNA and consisting of guanine linked to D-ribose via a β-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.] |
