Allgemeine Beschreibung

Polyguanylic acid takes up a four-stranded helical structure. It is synthetically produced in Thermus thermophilus from guanosine diphosphate (GDP) and its synthesis is catalyzed by the enzyme polynucleotide phosphorylase.

Anwendung

Polyguanylic acid (PolyG) is used to study the effects of ionizing radiation on formation and stability of G-quadruplex structures and as a target molecule for physicochemical studies of electronic excitation (vibrational spectra) of guanosine.
Polyguanylic acid potassium salt has been used:
  • as a ligand for surface neuropilin-1 (NRP1) for internalization studies
  • for intercalation studies with trisubstituted and disubstituted triazole-linked phenyl derivatives CL41, CL42 and CL2r50 using voltammetry method
  • as a synthetic polynucleotide for agarose gel electrophoresis analysis

Biochem./physiol. Wirkung

Polyguanylic acid acts as a ligand for scavenger receptor and reduces the surface expression neuropilin-1 in endothelial cells.

Ligand interaction with cognate cell-surface receptor often promotes receptor internalization, protecting cells from prolonged or excessive signaling from extracellular ligands. Compounds that induce internalization of surface receptors prevent ligand binding to cognate cell-surface receptors serving as inhibitors. Here, we show

The redox mechanism of two trisubstituted triazole-linked phenyl derivatives (CL41 and CL42) and a disubstituted triazole-linked phenyl derivative (CL2r50) were studied using cyclic, differential pulse and square wave voltammetry at a glassy carbon electrode. The CL41, CL42 and CL2r50 oxidation
