Aza-bridged bisphenanthrolinyl Pt(ii) complexes : efficient stabilization and topological selectivity on telomeric G-quadruplexes
Two platinum complexes with an aza-bridged bis(1,10-phenanthrolin-2-yl)amine (bpa) were synthesized. The two phenanthrolines in bpa entered a flat plane prior to binding of nucleic acids, which bestowed on the two Pt complexes a significantly high stabilizing ability on both DNA and RNA G-quadruplex...
