| Abstract: | The formation of the G‐quadruplex of the vascular endothelial growth factor (VEGF) gene was probed by electrospray ionization mass spectrometry (ESI‐MS). It found that cations (K+ and NH ), CH3OH and pH influence significantly the formation of the G‐quadruplex structure. Additionally, a perylene derivative (P3) and polydatin (P4) have shown to be potential G‐quadruplex binding agents with structurally specific recognition. Copyright © 2010 John Wiley & Sons, Ltd. |
