Abstract |
To visualize the guanine-quadruplex (G4) nucleic acids in cells or in biological tissues, near-infrared (NIR) fluorescent probes that can respond specifically to G4 nucleic acids are required. Herein, an NIR fluorescence switch-on probe for G4 imaging having higher selectivity and extremely large Stokes shift (ca. 220 nm) was successfully developed by the modification of our original tripodal quinone-cyanine fluorescent dye. The target binding-induced intramolecular stacking interaction of the probe might cause red shifting of the fluorescence emission. The NIR fluorescence switch-on probe developed here might contribute largely to revealing the behaviors of G4 nucleic acids not only in cells but also in biological tissues.
