“…For complex 8 , the arrangement of the atoms (two fleroxacin oxygen atoms, two phen nitrogen atoms and the Cl atom) in a distorted square pyramidal environment around the five-coordinate copper is similar to that of complexes 6 and 7 and a series of previously reported [Cu(quinolone)( N,N ′-donor)Cl] complexes [ 12 , 27 , 29 , 54 , 55 ].…”

A series of complexes of divalent transition metals (Cu(II), Mn(II), Zn(II), Co(II) and Ni(II)) with the quinolone antibacterial agent fleroxacin, in the absence or presence of an α-diimine such as 2,2′-bipyridine, 1,10-phenanthroline or 2,2′-bipyridylamine, were prepared and characterized. The complexes were characterized by various physicochemical and spectroscopic techniques and by single-crystal X-ray crystallography. The in vitro antibacterial activity of the complexes was studied against the bacterial strains Staphylococcus aureus, Bacillus subtilis and Xanthomonas campestris and was higher than that of free quinolone. The affinity of the complexes for bovine and human serum albumin was studied by fluorescence emission spectroscopy and the determined binding constants showed tight and reversible binding to the albumins. The interaction of the complexes with calf-thymus DNA was studied by various techniques, which showed that intercalation was the most plausible mode of interaction.

Formation of metal-radical species upon reduction of late transition metal complexes with heteroleptic ligands: an experimental and theoretical study

Abstract: A series of three new metal complexes with selenadiazoloquinolones, known as broad spectrum antibiotics in clinical praxis, namely [Co(E4h)2(phen)]∙8H2O (1), [Ni(E4h)2(phen)]∙8H2O (2) and [Cu(E4h)(phen)Cl)]∙5H2O (3), have been synthesized and fully...
