Guanosine 5′-monophosphate is suitable for use in:
  • the measurement of density and viscosity of nucleotide and along with the furanose sugar from 0.0004 to 0.0014mol/kg solution at 288.15, 293.15 and 298.15K at atmospheric pressure
  • the detection and validation of a transcreener assay for detection of AMP- and GMP-producing enzymes
  • the preparation of nucleotide standard during the quantitative profiling of nucleotides using capillary IC-MS/MS

Biochem/physiol Actions

Guanosine 5′-monophosphate (GMP) is a ribonucleoside monophospate which upon phosphorylation to GTP becomes incorporated into ribonucleic acids (RNAs) by various RNA polymerase(s). Guanosine-5′-monophosphate (GMP) can be used to study modulation of glutamatergic neurotransmission.

The glutamatergic system has received considerable attention over the last few years as potential target to develop anxiolytic drugs. Guanine based purines (GBPs) play an important neurmodulatory effect in the glutamatergic system. Several studies have shown the ability of the...

The photodecomposition mechanism of trans,trans,trans-[Pt(N3 )2 (OH)2 (py)2 ] (1, py=pyridine), an anticancer prodrug candidate, was probed using complementary Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR), transient electronic absorption, and UV/Vis spectroscopy. Data fitting using Principal Component Analysis (PCA) and...

Overstimulation of the glutamatergic system (excitotoxicity) is involved in various acute and chronic brain diseases. Several studies support the hypothesis that guanosine-5'-monophosphate (GMP) can modulate glutamatergic neurotransmission. The aim of this study was to evaluate the effects of chronically administered...

Metabolic profiling has become an important tool in biological research, and the chromatographic separation of metabolites coupled with mass spectrometric detection is the most frequently used approach for such studies. The establishment of robust chromatographic methods for comprehensive coverage of...

Screening of AMP- and GMP-producing enzymes such as phosphodiesterases (PDEs), ligases, and synthetases would be simplified by the ability to directly detect unmodified nucleoside monophosphates. To address this need, we developed polyclonal and monoclonal antibodies that recognize AMP and GMP...
