Abstract
Three seriesof metalsalophencomplexesderivedfromZn2+,Cu2+, Pt2+and Ni2+havebeensynthesizedand their interaction with quadruplex DNA has been evaluated. The compounds differ on the number of ethylpiperidinesubstituents.They have been characterized by 1H NMR, IR and UV-visible spectroscopies and by HR-masss pectrometry.Their luminescent properties have been also evaluated and we can observe that, as expected,Zn2+and Pt2+complexesare those displaying more interesting luminescence with an emission band red-shifted with respect to the corresponding uncoordinated ligand. DNAinteractionswithG4 and duplex DNA were evaluated by FRET melting assays(for the Zn2+, Cu2+and Ni2+complexes)and by emission titrations(for one Pt2+complex)which indicated that the disubstitutedcompounds2-Niand2-Ptare the only onesthat display good affinityfor G4 DNAstructures| File | Dimensione | Formato | |
