Synergy between quantum dots and 1,10-phenanthroline–copper(ii) complex towards cleaving DNA

2011

We have found that the DNA cleaving activity of quantum dots and 1,10-phenanthroline-Cu(II) complex is significantly enhanced when they are combined.

Two Novel Ternary Dicopper(II) μ-Guanazole Complexes with Aromatic Amines Strongly Activated by Quantum Dots for DNA Cleavage

2013

Two novel (μ-guanazole)-bridged binuclear copper(II) complexes with 1,10-phenanthroline (phen) or 2,2'-bipyridine (bipy), [Cu2(μ-N2,N4-Hdatrz)(phen)2(H2O)(NO3)4] (1) and [Cu2(μ-N1,N2-datrz)2(μ-OH2)(bipy)2](ClO4)2 (2) (Hdatrz = 3,5-diamino-1,2,4-triazole = guanazole), have been prepared and characterized by X-ray diffraction, spectroscopy, and susceptibility measurements. Compounds 1 and 2 differ in the aromatic amine, which acts as a coligand, and in the Cu···Cu'-bridging system. Compound 1, which contains two mono-bridged copper ions, represents the first example of a discrete Cu-(NCN-trz)-Cu' complex. Compound 2, with two triply bridged copper ions, is one of the few compounds featuring a…

A dinucleating ligand which promotes DNA cleavage with one and without a transition metal ion.

2013

The dinucleating ligand L (1,3-bis[bis(pyridin-2-ylmethyl)amino]propan-2-ol) combined with metal ions efficiently cleaves DNA when M : L is 1 : 1 (M = Co(II) or Fe(III)) at pH 5.5–7.0, with free L being more active at acidic pH than when bound to Zn(II), Cu(II) or Ni(II) at neutral pH.
