Exclusive platination of loop adenines in the human telomeric G-quadruplex†
Abstract
The present article reports on the platination of the human telomeric G-quadruplex by three Pt-terpyridine complexes. It is shown that extension of the aromatic surface of the terpyridine moiety surrounding the platinum atom influences both the binding affinity and the platination activity. Remarkably, the most strongly bound complex Pt-ttpy coordinates exclusively the adenine
