Application

PhenDC3 has been used:
  • as a quadruplex (G4) ligand to study its effects on the binding of RNA quadruplex (rG4) to nucleolin (NCL)
  • as a DNA/RNA G-quadruplexes (GQs) ligand to study its effects on the expression of double homeobox 4 (DUX4) gene
  • as a G4 ligand to study its stability and selectivity towards pre-miR-92b rG4 complex and duplex DNA by fluorescence resonance energy transfer (FRET)-melting assay

Biochem/physiol Actions

PhenDC3 (Phen-DC3) is a bisquinolinium-derivatized phenanthroline-dicarboxamide that targets both DNA and RNA G-quadruplex (G4) structure with high affinity (DNA DC50 in μM = 0.31/22AG K+, 0.25/22AG Na+, 0.30/TBA; RNA DC50 in μM = 0.11/(G3U)3G3, 0.12/(G3U2)3G3, 0.16/(G3U3)3G3) and selectivity (duplex DNA DC50 >2.5 μM). PhenDC3 suppresses the translation of reporter mRNA constructs with 5′UTR G4 structure, but not those without, in cell-based reporter assays (0.1-10 μM) and reduces telomerase processivity by promoting telomerase dissociation from its product during elongation. NMR analysis shows that PhenDC3 interacts with the quadruplex through extensive stacking with the guanine bases of the top G-quartet. A powerful benchmark tool for probing and elucidating the biological roles of cellular DNA and RNA G4 sturctures.

Quadruplex ligands are often considered as telomerase inhibitors. Given the fact that some of these molecules are present in the clinical setting, it is important to establish the validity of this assertion. To analyze the effects of these compounds, we

We have designed AS1411-N6, a derivative of the nucleolin (NCL)-binding aptamer AS1411, by adding six nucleotides to the 5'-end that are complementary to nucleotides at the 3'-end forcing it into a stem-loop structure. We evaluated by several biophysical techniques if

A high level of nucleolin (NCL) expression is often associated with a poor prognosis of patients with lung cancer (LC), suggesting that NCL can be used as a possible biomarker. NCL has been shown to display a marked preference for

G-quadruplexes (G4) are polymorphic four-stranded structures formed by certain G-rich nucleic acids in vitro, but the sequence and structural features dictating their formation and function in vivo remains uncertain. Here we report a structure-function analysis of the complex hCEB1 G4-forming

The identification of G-quadruplex (G4) binding proteins and insights into their mechanism of action are important for understanding the regulatory functions of G4 structures. Here, we performed an unbiased affinity-purification assay coupled with mass spectrometry and identified 30 putative G4
