Binding properties of mono- and dimeric pyridine dicarboxamide ligands to human telomeric higher-order G-quadruplex structures

Résumé

Here, we report on the in vitro binding properties of the known pyridine dicarboxamide G-quadruplex ligand 360A and a new dimeric analogue (360A)2A to human telomeric DNA higher-order G-quadruplex (G4) structures. This study points to original binding features never reported for G4 ligands, and reveals a greater efficiency for the dimeric ligand to displace RPA (a ssDNA binding protein involved in telomere replication) from telomeric DNA.
