Copper(II) complexes with the non-steroidal anti-inflammatory drug tolfenamic acid (Htolf) with the oxygen-donor ligands methanol (MeOH) or N,N-dimethylformamide (DMF) and/or the nitrogen-donor heterocyclic ligands 2,2?-bipyridine (bipy), 2,2?-bipyridylamine (bipyam), 1,10-phenanthroline (phen) or pyridine (py) were synthesized and characterized. The crystal structures of five novel complexes were determined by X-ray crystallography where tolfenamic acid is deprotonated being in different binding modes. Equimolar quantities of CuCl2, tolf- 1 and bipy led to the formation of [Cu(tolf-O,O?)(bipy)Cl] (1), while with a 1:2 Cu(II):tolf ratio, complexes [Cu(tolf-O,O?)2(bipy)] (2), [Cu(tolf-O,O?)2(bipyam)]¡¤0.5MeOH (3 0.5MeOH), [Cu(tolf-O,O?)(tolf-O)(phen)(MeOH)] (4) and [Cu(tolf-O)2(py)2(MeOH)2] (5) were isolated. The interaction of the complexes with serum albumin proteins was studied by fluorescence spectroscopy with the determined binding constant bearing relative high values. The scavenging ability of the complexes towards 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals was investigated and the in vitro inhibitory activity against soybean lipoxygenase was evaluated and complexes 4 and 5 were the more active compounds among those tested. Spectroscopic (UV), electrochemical (cyclic voltammetry) and physicochemical (viscosity measurements) techniques were employed in order to study the binding mode and strength of the complexes to calf-thymus (CT) DNA suggesting intercalation as the most possible mode of binding. Competitive studies with ethidium bromide (EB) revealed the ability of the complexes to displace the DNA-bound EB. The biological properties of complexes 1-5 were evaluated in regard to previously reported complex [Cu2(tolf-O,O?)4(DMF)2] (6).

In the present contribution, the synthesis and the characterization of the manganese(II) complexes with the quinolone antimicrobial agent flumequine (Hflmq) in the absence or presence of the N,N?-donor heterocyclic ligands 1,10-phenanthroline (phen) and 2,2?-bipyridylamine (bipyam) are reported. The structure of complex [Mn(flmq)2(phen)]¡¤2MeOH was also determined by X-ray crystallography. In the novel complexes, the quinolone ligands are bound to manganese(II) in a bidentate manner through a carboxylato oxygen and the pyridone oxygen. The affinity of the complexes to human or bovine serum albumin proteins was investigated by fluorescence emission spectroscopy and the corresponding binding constants exhibit relatively high values. The binding of the complexes to calf-thymus (CT) DNA was studied by UV?Vis spectroscopy and DNA-viscosity measurements. The DNA-binding constants of the complexes were calculated. Intercalation is the most possible DNA-binding mode, and this was verified through the ability of the complexes to displace ethidium bromide (EB) from the EB?DNA conjugate. The antimicrobial activity of the complexes was tested against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis) and was found similar or higher than free Hflmq.

This study provides an opportunity to control the magnetic spin of nickel atoms using various mixed anionic ligands. A series of linear trinickel complexes supported by two kinds of ligands, oligo-alpha-pyridylamido and sulfonyl amido/amido, were synthesized and their structures were determined by X-ray diffraction. The three nickel atoms of [Ni3(Lpts) 2(dpa)2] (1) (dpa- = dipyridylamido, Lpts 2- = N,N?-bis(p-toluenesulfonyl)pyridyldiamido) display short Ni-N (?1.90 A) bond distances, which are consistent with a low spin state of Ni(ii) ions, and exhibit spin states of (0, 0, 0) for the three Ni(ii) ions. One of the terminal Ni(ii) ions of [Ni3(Lms) 2(dpa)2(H2O)] (2) (Lms2- = N,N?-bis(4-methylsulfonyl)-pyridyldiamido) and [Ni3(Lpts) 2(pepteaH2)] (4) (pepteaH22- = pentapyridyldiamidodiamine) bonded with an axial ligand exhibits a square pyramidal (NiN4X) geometry with long Ni-N bond distances (?2.10 A) which are consistent with a high spin Ni(ii) configuration. The spin states of these trinickel complexes are (1, 0, 0). Complex 2 and 6 can be interchanged by the removal or addition of an axial water molecule. The structural features of 6 are comparable with those of 1. Both the terminal Ni(ii) ions in [Ni3(LAc)2(dpa)2] (3) (Lac 2- = N,N?-biacetyl-pyridyldiamido) are in square pyramidal geometry and exhibit high spin. The spin states of the nickel ions in 3 are (1, 0, 1), and the two terminal nickel ions exhibit antiferromagnetic interactions. The molecular structure of [Ni3(Lpts)2(dpa) 2](BF4) (5), which was obtained by the one-electron oxidation of 1, is similar to those of the neutral analogue 1, except for the presence of a counter anion to compensate for the positive charge on the Ni 3 core. All of the Ni-Ni bond lengths of 5 are slightly shorter (ca. 0.05 A) than those in the neutral analogues. This is attributed to the formation of partial Ni-Ni bonding.

The target-guided, in situ click chemistry approach to lead discovery has been successfully employed for discovering acetylcholinesterase (AChE) inhibitors by incubating a selected enzyme/tacrine azide combination with a variety of acetylene reagents that were not previously known to interact with the enzyme’s peripheral binding site. The triazole products, formed by the enzyme, were identified by HPLC-mass spectrometry analysis of the crude reaction mixtures. The target-guided lead discovery search was also successful when performed with reagent mixtures containing up to 10 components. From 23 acetylene reagents, the enzyme selected two phenyltetrahydroisoquinoline (PIQ) building blocks that combined with the tacrine azide within the active center gorge to form multivalent inhibitors that simultaneously associate with the active and peripheral binding sites. These new inhibitors are up to 3 times as potent as our previous phenylphenanthridinium-derived compounds, and with dissociation constants as low as 33 femtomolar, they are the most potent noncovalent AChE inhibitors known. In addition, the new compounds lack a permanent positive charge and aniline groups and possess fewer fused aromatic rings. Remarkably, despite the high binding affinity, the enzyme displayed a surprisingly low preference for one PIQ enantiomer over the other.

The preparation of stable Lewis base adducts of CuL (H2L=Schiff base derived from the condensation of o-hydroxypropiophenone (OHP) and salicylhydrazide (SHZ)) is described. The N-donors bipy and bipyam ligands (bipy=2,2?-bipyridyl; bipyam=2,2?-bipyridylamine) give the complexes [Cu(OHP-SHZ)(bipy)] (I) and [Cu(OHP-SHZ)(bipyam)]H2O (II) which have been characterized by physical and spectroscopic techniques. Crystals of I are orthorhombic, space group Pcab, with a=10.221(3), b=12.643(3), c=35.448(3) A, V=4581(2) A3 and Z=8. The structure of complex I is shown to comprise discrete monomeric [Cu(OHP-SHZ)(bipy)] molecules in which the Cu(II) atom environment exhibits a highly distorted five-coordinated geometry. Crystals of II are monoclinic, space group C2/c, with a=24.804(3), b=13.231(3), c=14.739(3) A, beta=99.57(2), V=4770(2) A3 and Z=8. The structure of this complex consists of discrete entities associated into H-bonded binuclear units via the lattice water molecules. The coordination sphere around the copper center is nearly square pyramidal. The transition from a six-membered chelated ring to a five-membered one results in a less distorted coordination polyhedron around the Cu(II) ion. In both complexes the OHP-SHZ ligand occupies three of the coordination sites through the same (ONO) donor atoms while the remaining positions are occupied by the pyridine N atoms. EPR spectra provide evidence of the existence of very weak magnetic exchange coupling in the complex [Cu(OHP-SHZ)(bipyam)]H2O (II). Thermogravimetric and differential scanning calorimetric studies of complex I show that this complex loses the bipy molecule through an endothermic process with DeltaH=81.75 kJ mol-1. The best kinetic parameter values corresponding to the process involving the loss of the bipy molecule were found on the basis of the agreement between non-isothermal and isothermal methods and are given by the Abou-Shaaban-Simonelli equation in isothermal conditions. The better representation of the reaction mechanism is the phase-boundary, spherical symmetry reaction.
