Abstract
The unprecedented mononucleated ligand (6,6-di(1H-indol-3-yl)-N,N-bis(pyridin-2-ylmethyl)hexan-1-amine (LC5) with an N3-donor set and its complexes [Zn(LC5)Cl2] • 2CH3OH (1) and [Zn(LC5)2](ClO4)2 (2), were successfully prepared. All compounds were fully characterized by a suite of physicochemical methods. Fluid 1H and 13C NMR spectroscopy, as well as DFT and TD-DFT calculations, were carried out to propose a viable structural arrangement for both complexes. The interaction between these compounds and DNA was monitored in the UV region where binding constants (Kb) were estimated (2 > 1 > LC5). These data were corroborated by DNA cleavage assays using groove binders, circular dichroism, and docking studies. Both complexes confirmed their biocide activity against selected microorganisms: Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria, the filamentous fungi A. fumigatus and S. cerevisiae. Finally, the cytotoxic activities of 1 and 2 were tested against the erythroleukemia K562 cell line. For all biological studies, it was probed that the presence of the indole moieties and the zinc atoms in the chemical composition of the complexes studied could increase the magnitude of the activity following the order: 2 > 1 > LC5, where a linear relationship between the biological activity upon K562 cells (IC50) and DNA binding studies (Kb) was found.
