The effect of potential supramolecular-bond promoters on the DNA-interacting abilities of copper-terpyridine compounds. Grau, Jordi (Grau Bigordà) Brissos, Rosa F. Salinas Uber, Jorge Caballero Hernández, Ana Belén Caubet Marín, Amparo Roubeau, Olivier Korrodi-Gregório, Luís Pérez Tomás, Ricardo E. Gámez Enamorado, Patrick Coure Lligands Mort cel·lular Càncer Compostos de metalls de transició Copper Ligands Cell death Cancer Three copper(II) coordination compounds have been prepared from three different 2,2′:6′,2′′-terpyridine-based ligands, which have been selected to investigate the potential role of supramolecular interactions on the DNA-interacting and cytotoxicity properties of the corresponding metal complexes. Hence, the ligands 4′-((naphthalen-2-yl)methoxy)-2,2′:6′,2′′-terpyridine (Naphtpy) and 4′-((1H-benzo[d]imidazol-2-yl)methoxy)-2,2′:6′,2′′-terpyridine (Bimztpy) have been synthesized from commercially-available 4′-chloro-2,2′:6′,2′′-terpyridine (Cltpy), and their copper(II) complexes have been obtained by reaction with copper(II) nitrate. The DNA-interacting abilities of the corresponding compounds [Cu(Cltpy)(H2O)(NO3)2] (1), [Cu(naphtpy)(NO3)(H2O)](NO3)(MeOH) (2) and [Cu(bimztpy)(NO3)(H2O)](NO3) (3) have been investigated using different techniques, and cytotoxicity assays with several cancer cell lines have revealed interesting features, viz. the more efficient complex is 2, which although it does not act as a DNA cleaver, displays the most effective DNA-interacting and cytotoxic properties, compared to 1 and 3. 2015-11-10T11:42:47Z 2016-08-03T22:01:16Z 2015-08-03 2015-11-10T11:42:47Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 1477-9226 https://hdl.handle.net/2445/67721 653985 eng Versió postprint del document publicat a: http://dx.doi.org/10.1039/c5dt02211h Dalton Transactions, 2015, vol. 44, p. 16061-16072 http://dx.doi.org/10.1039/c5dt02211h (c) Grau, Jordi et al., 2015 info:eu-repo/semantics/openAccess 12 p. application/pdf Royal Society of Chemistry Articles publicats en revistes (Química Inorgànica i Orgànica)
