A Novel Platinum Complex as Telomeric G-Quadruplex Binders

Abstract

A new platinum (II) complex has been synthesized and characterized by IR, NMR, ESI-MS and element analysis. The affinities of the complex toward telomeric G-quadruplex DNA [Htel-21] has been investigated by CD, UVVis. The results revealed that the complex can induce and stabilizes the antiparallel telomeric G-quadruplex DNA, and bind very strongly to G-quadruplex DNA. The inhibition ratio of the complex was screened against four cancer cell lines in comparison to cisplatin and it showed a higher activity than cisplatin.
