AB  - Inspired by the emergence of resistance to currently available antifungal therapy and by the great potential of metal complexes for the treatment of various diseases, we synthesized three new silver(I) complexes containing clinically used antifungal azoles as ligands, [Ag(ecz)2]SbF6 (1, ecz is econazole), {[Ag(vcz)2]SbF6}n (2, vcz is voriconazole), and [Ag(ctz)2]SbF6 (3, ctz is clotrimazole), and investigated their antimicrobial properties. The synthesized complexes were characterized by mass spectrometry, IR, UV-vis and 1H NMR spectroscopy, cyclic voltammetry, and single-crystal X-ray diffraction analysis. In the mononuclear complexes 1 and 3 with ecz and ctz, respectively, the silver(I) ion has the expected linear geometry, in which the azoles are monodentately coordinated to this metal center through the N3 imidazole nitrogen atom. In contrast, the vcz-containing complex 2 has a polymeric structure in the solid state in which the silver(I) ions are coordinated by four nitrogen atoms in a distorted tetrahedral geometry. DFT calculations were done to predict the most favorable structures of the studied complexes in DMSO solution. All the studied silver(I) complexes have shown excellent antifungal and good to moderate antibacterial activities with minimal inhibitory concentration (MIC) values in the ranges of 0.01–27.1 and 2.61–47.9 μM on the selected panel of fungi and bacteria, respectively. Importantly, the complexes 1–3 have exhibited a significantly improved antifungal activity compared to the free azoles, with the most pronounced effect observed in the case of complex 2 compared to the parent vcz against Candida glabrata with an increase of activity by five orders of magnitude. Moreover, the silver(I)-azole complexes 2 and 3 significantly inhibited the formation of C. albicans hyphae and biofilms at the subinhibitory concentration of 50% MIC. To investigate the impact of the complex 3 more thoroughly on Candida pathogenesis, its effect on the adherence of C. albicans to A549 cells (human adenocarcinoma alveolar basal epithelial cells), as an initial step of the invasion of host cells, was studied.

AB  - Dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz) was used as a ligand for the synthesis of new copper(II) and silver(I) complexes, [CuCl2(py-2pz)]2 (1), [Cu(CF3SO3)(H2O)(py-2pz)2]CF3SO3·2H2O (2), [Ag(py-2pz)2]PF6 (3) and {[Ag(NO3)(py-2pz)]·0.5H2O}n (4). The complexes were characterized by spectroscopic and electrochemical methods, while their structures were determined by single crystal X-ray diffraction analysis. The X-ray analysis revealed the bidentate coordination mode of py-2pz to the corresponding metal ion via its pyridine and pyrazine nitrogen atoms in all complexes, while in polynuclear complex 4, the heterocyclic pyrazine ring of one py-2pz additionally behaves as a bridging ligand between two Ag(I) ions. DFT calculations were performed to elucidate the structures of the investigated complexes in solution. The antimicrobial potential of the complexes 1–4 was evaluated against two bacterial (Pseudomonas aeruginosa and Staphylococcus aureus) and two Candida (C. albicans and C. parapsilosis) species. Silver(I) complexes 3 and 4 have shown good antibacterial and antifungal properties with minimal inhibitory concentration (MIC) values ranging from 4.9 to 39.0 μM (3.9–31.2 μg mL−1). All complexes inhibited the filamentation of C. albicans and hyphae formation, while silver(I) complexes 3 and 4 had also the ability to inhibit the biofilm formation process of this fungus. The binding affinity of the complexes 1–4 with calf thymus DNA (ct-DNA) and bovine serum albumin (BSA) was studied by fluorescence emission spectroscopy to clarify the mode of their antimicrobial activity. Catechol oxidase biomimetic catalytic activity of copper(II) complexes 1 and 2 was additionally investigated by using 3,5-di-tert-butylcatechol (3,5-DTBC) and o-aminophenol (OAP) as substrates.

AB  - Dimethyl 6-(pyrazine-2-yl)pyridine-3,4-dicarboxylate (py-2pz) was used as a ligand for the synthesis of new copper(II) and silver(I) complexes, [CuCl2(py-2pz)]2 (1), [Cu(CF3SO3)(H2O)(py-2pz)2]CF3SO3·2H2O (2), [Ag(py-2pz)2]PF6 (3) and {[Ag(NO3)(py-2pz)]·0.5H2O}n (4). The complexes were characterized by spectroscopic and electrochemical methods, while their structures were determined by single crystal X-ray diffraction analysis. The X-ray analysis revealed the bidentate coordination mode of py-2pz to the corresponding metal ion via its pyridine and pyrazine nitrogen atoms in all complexes, while in polynuclear complex 4, the heterocyclic pyrazine ring of one py-2pz additionally behaves as a bridging ligand between two Ag(I) ions. DFT calculations were performed to elucidate the structures of the investigated complexes in solution. The antimicrobial potential of the complexes 1–4 was evaluated against two bacterial (Pseudomonas aeruginosa and Staphylococcus aureus) and two Candida (C. albicans and C. parapsilosis) species. Silver(I) complexes 3 and 4 have shown good antibacterial and antifungal properties with minimal inhibitory concentration (MIC) values ranging from 4.9 to 39.0 μM (3.9–31.2 μg mL−1). All complexes inhibited the filamentation of C. albicans and hyphae formation, while silver(I) complexes 3 and 4 had also the ability to inhibit the biofilm formation process of this fungus. The binding affinity of the complexes 1–4 with calf thymus DNA (ct-DNA) and bovine serum albumin (BSA) was studied by fluorescence emission spectroscopy to clarify the mode of their antimicrobial activity. Catechol oxidase biomimetic catalytic activity of copper(II) complexes 1 and 2 was additionally investigated by using 3,5-di-tert-butylcatechol (3,5-DTBC) and o-aminophenol (OAP) as substrates.

AB  - The hydrolysis of N-acetylated L-methionylglycine dipeptide (Ac-L-Met-Gly) in the presence of dinuclear platinum(II)-aqua complexes with general formula [{Pt(L)(H2O)}2(μ-1,5-nphe)]4+ (1,5-nphe is 1,5-naphthyridine; L is bidentately coordinated ethylenediamine (1w), (±)-1,2-propylenediamine (2w) and 1,3-propylenediamine (3w)) is described in detail. The hydrolytic activity of these complexes was monitored by 1H NMR spectroscopy, which confirmed the regioselective cleavage of the Met-Gly-amide bond in this peptide. Quantum-chemical calculations revealed the primary reaction path with coordination of dipeptide via the terminal amide nitrogen of methionine followed by its coordination for the sulphur atom, in which the decomposition of the resulted platinum(II)-dipeptide complex and the coordination of its glycine residue precedes the hydrolytic cleavage of the Met-Gly amide bond. In the secondary reaction path, in which Ac-L-Met-Gly is coordinated via the methionine sulphur atom, the decomposition of the starting [{Pt(L)(H2O)}2(μ-1,5-nphe)]4+ complex is followed by the regioselective hydrolysis of the investigated dipeptide. The binding affinity of the chloride derivatives of the corresponding dinuclear platinum(II)-aqua complexes, [{Pt(L)Cl}2(μ-1,5-nphe)]2+ (1–3) towards the human serum albumin (HSA), a transport protein, was investigated using electronic absorption and fluorescence emission measurements, and results indicated the static interactions between these complexes and HSA. A docking study revealed a unique binding site on HSA, based on the electrostatic and the hydrogen bonding, which does not have a methionine residue nearby, therefore does not exist danger of HSA hydrolysis by these complexes.

AB  - To investigate how modification in the structure of 1,3-propanediamine chain of 1,3-pdta (1,3-propanediamine-N,N,N′,N′-tetraacetate) ligand affects the structural and biological properties of the corresponding metal complexes, two new octahedral complexes, [Co(H2O)5Co(2,2-diMe-1,3-pdta)]·H2O (1) and [Mg(H2O)5Mg(2,2-diMe-1,3-pdta)]·1.5H2O (2) (2,2-diMe-1,3-pdta = 2,2-dimethyl-1,3-propanediamine-N,N,N′,N′-tetraacetate), were synthesized and characterized by IR spectroscopy and single-crystal X-ray diffraction analysis. Additionally, UV-Vis and NMR spectroscopic methods were applied for the characterization of 1 and 2, respectively. Crystallographic data indicate that these complexes contain 2,2-diMe-1,3-pdta coordinated to the metal ion through 2 N and 4 O atoms forming [M(H2O)5M′(2,2-diMe-1,3-pdta)] complex unit (M, M′ = Co(II), Co(II) (1) and M, M′ = Mg(II), Mg(II) (2)), which is composed of [M′(2,2-diMe-1,3-pdta)]2− and [M(H2O)5O]2+ octahedra bridged by one of the axial carboxylate groups. The antimicrobial activities of 1 and 2 were evaluated against different bacteria and Candida spp., while their cytotoxic effect was tested on the normal human lung fibroblasts (MRC-5). The ability of 1 and 2 to inhibit formation of C. glabrata biofilms was also assessed. The obtained structural parameters and biological properties of the two complexes were compared to Co(II) and Mg(II) complexes with 1,3-pdta ligand.

AB  - The mechanism of action of most approved drugs in use today is based on their binding to specific proteins or DNA. One
of the achievements of this research is a new perspective for recognition of binding modes to DNA by monitoring of
changes in measured and stoichiometric values of absorbance at 260 nm. UV–Vis and IR spectroscopy, gel electrophoresis
and docking study were used for investigation of binding properties of three dinuclear platinum(II) complexes containing
different pyridine-based bridging ligands, [{Pt(en)Cl}2(μ-4,4’-bipy)]Cl2・2H2O (Pt1), [{Pt(en)Cl}2(μ-bpa)]Cl2・4H2O (Pt2)
and [{Pt(en)Cl}2(μ-bpe)]Cl2・4H2O (Pt3) to DNA (4,4’-bipy, bpa and bpe are 4,4′-bipyridine, 1,2-bis(4-pyridyl)ethane and
1,2-bis(4-pyridyl)ethene, respectively). In contrast to the system with well-known intercalated ligand (EtBr), covalently bound
ligand (cis-Pt) and with minor groove binder (Hoechst 33258), which do not have significant differences in measured and
stoichiometric values, the most pronounced deviations are recorded for two dinuclear platinum(II) complexes (Pt1 and Pt2),
as a consequence of complex binding to the phosphate backbone and bending of DNA helix. The hydrolysis of complexes
and changes in DNA conformation were also analysed as phenomena that may have an impact on the changes in absorbance.

AB  - The article presents an overview of the results achieved during the last several decades on the synthesis and structural characterization of copper(II) complexes with different aminopolycarboxylates. Considering the structural varieties in designing aminopolycarboxylate ligands and significant stereochemical flexibility of the corresponding copper(II) complexes to adopt a wide range of coordination geometries, this review is mainly focused on the results related to the crystallographic characterization of the synthesized complexes. The ligands used for the synthesis of copper(II) complexes described in this article contain two amine nitrogen atoms and different number of the carboxylate oxygen donor atoms (N2O2, N2O3 and N2O4-type of ligands). Giving the importance to the biological relevance of the Cu(II) ion and broad aspects of potential application of aminopolycarboxylate ligands in human practice, the presented results could have some important implications for coordination chemists dealing with structural properties of aminopolycarboxylate-copper(II) complexes and their potential medicinal and biological applications.

AB  - Mononuclear silver(I) complexes with 1,7-phenanthroline (1,7-phen), [Ag(NO3-O,O') (1,7-phen-N7)(2)] (1) and [Ag(1,7-phen-N7)(2)]X, X = ClO4- (2), CF3SO3- (3), BF4- (4) and SbF6- (5) were synthesized and structurally characterized by NMR (H-1 and C-13), IR and UV-Vis spectroscopy and ESI mass spectrometry. The crystal structures of 1, 3 and 4 were determined by single-crystal X-ray diffraction analysis. In all these complexes, 1,7-phen coordinates to the Ag(I) ion in a monodentate fashion via the less sterically hindered N7 nitrogen atom. The investigation of the solution stability of 1-5 in DMSO revealed that they are sufficiently stable in this solvent at room temperature. Complexes 1-5 showed selectivity towards Candida spp. in comparison to bacteria, effectively inhibiting the growth of four different Candida species with minimal inhibitory concentrations (MIC) between 1.2 and 11.3 mu M. Based on the lowest MIC values and the lowest cytotoxicity against healthy human fibroblasts with selectivity index of more than 30, the antifungal potential was examined in detail for the complex 1. It had the ability to attenuate C. albicans virulence and to reduce epithelial cell damage in the cell infection model. Induction of reactive oxygen species (ROS) response has been detected in C. albicans, with fungal DNA being one of the possible target biomolecules. The toxicity profile of 1 in the zebrafish model (Danio rerio) revealed improved safety and activity in comparison to that of clinically utilized silver(I) sulfadiazine.

AB  - The synthesis, spectroscopic characterization, cytotoxic activity and DNA binding evaluation of seven new dinuclear platinum(ii) complexes Pt1-Pt7, with the general formula [{Pt(L)Cl}(2)(-1,5-nphe)](ClO4)(2) (1,5-nphe is 1,5-naphthyridine; while L is two ammines (Pt1) or one bidentate coordinated diamine: ethylenediamine (Pt2), (+/-)-1,2-propylenediamine (Pt3), trans-(+/-)-1,2-diaminocyclohexane (Pt4), 1,3-propylenediamine (Pt5), 2,2-dimethyl-1,3-propylenediamine (Pt6), and 1,3-pentanediamine (Pt7)), were reported. In vitro cytotoxic activity of these complexes was evaluated against three tumor cell lines, murine colon carcinoma (CT26), murine mammary carcinoma (4T1) and murine lung cancer (LLC1) and two normal cell lines, murine mesenchymal stem cells (MSC) and human fibroblast (MRC-5) cells. The results of the MTT assay indicate that all investigated complexes have almost no cytotoxic effects on 4T1 and very low cytotoxicity toward LLC1 cell lines. In contrast to the effects on LLC1 and 4T1 cells, complexes Pt1 and Pt2 had significant cytotoxic activity toward CT26 cells. Complex Pt1 had a much lower IC50 value for activity on CT26 cells compared with cisplatin. In comparison with cisplatin, all dinuclear Pt1-Pt7 complexes showed lower cytotoxicity toward normal MSC and MRC-5 cells. In order to measure the amount of platinum(ii) complexes taken up by the cells, we quantified the cellular platinum content using inductively coupled plasma mass spectrometry (ICP-QMS). Molecular docking studies performed to evaluate the potential binding mode of dinuclear platinum(ii) complexes Pt1-Pt7 and their aqua derivatives W1-W7, respectively, at the double stranded DNA showed that groove spanning and backbone tracking are the most stable binding modes.

AB  - Gold(III) complexes with 1,7- and 4,7-phenanthroline ligands, [AuCl3(1,7-phen-kappa N7)] (1) and [AuCl3(4,7-phen-kappa N4)] (2) were synthesized and structurally characterized by spectroscopic (NMR, IR and UV-vis) and single crystal X-ray diffraction techniques. In these complexes, 1,7- and 4,7-phenanthrolines are monodentatedly coordinated to the Au(III) ion through the N7 and N4 nitrogen atoms, respectively. In comparison to the clinically relevant anti-angiogenic compounds auranofin and sunitinib, gold(III)-phenanthroline complexes showed from 1.5- to 20-fold higher anti-angiogenic potential, and 13- and 118-fold lower toxicity. Among the tested compounds, complex 1 was the most potent and may be an excellent anti-angiogenic drug candidate, since it showed strong anti-angiogenic activity in zebrafish embryos achieving IC50 value (concentration resulting in an anti-angiogenic phenotype at 50% of embryos) of 2.89 mu M, while had low toxicity with LC50 value (the concentration inducing the lethal effect of 50% embryos) of 128 mu M. Molecular docking study revealed that both complexes and ligands could suppress angiogenesis targeting the multiple major regulators of angiogenesis, such as the vascular endothelial growth factor receptor (VEGFR-2), the matrix metalloproteases (MMP-2 and MMP-9), and thioredoxin reductase (TrxR1), where the complexes showed higher binding affinity in comparison to ligands, and particularly to auranofin, but comparable to sunitinib, an anti-angiogenic drug of clinical relevance.

AB  - Structural variations modulated by ethyl side group have been analyzed for nickel(II) and copper(II) complexes with (+/-)-1,3-pentanediamine-N,N,N',N'-tetraacetate ligand (1,3-pndta) and its pentadentate derivative (+/-)-1,3-pentanediamine-N,N,N'-triacetate (1,3-pnd3a). X-ray results obtained for the octahedral 1,3-pndta-Ni(II) complex indicate the distinct correlation of the central chirality of the metal with the chirality at the diamine alpha-carbon, which leads to the formation of a racemic mixture of Delta Lambda Delta(R) and Lambda Delta Lambda(S) enantiomeric anionic complexes, where the R and S labels designate the absolute configuration at the ligand (ethyl-substituted) stereogenic center. These stereoisomers are those required to maintain an equatorial ethyl group on the central six-membered chelate ring, whose conformation is lambda twist-boat for the Delta Lambda Delta isomer and 8 twist-boat for the Lambda Delta Lambda isomer. Ethyl group discernibly affects the variation of the Ni-N and Ni-O bond lengths compared to the analogous complex lacking the substitution of one of the diastereotopic diamine CH2 hydrogens and functions as steric bulkiness which hampers an efficient and of high symmetry packing, observed in the crystals of the parent complex.

AB  - This paper reports the synthesis and X-ray characteristics of the missing homonuclear s-block metal complex {[Sr-2(1,3-pdta)(H2O)(6)]center dot H2O}(n). In the title compound, the hexadentate 1,3-propanediaminetetraacetate (1,3-pdta) ligand joins to two Sr(II) centers via the diamine chain. Moreover, each Sr(II) is bridged through two carboxylate O atoms and a water molecule to two neighboring Sr(II) ions. The coordination sphere around each Sr(II) ion consists of one diamine nitrogen, four carboxylate oxygens and four water molecules. Comparison with the previously reported M(II)-1,3-pdta complexes reveals that increasing of the ion size results in the incorporation of water molecules into its first coordination sphere and consequent increase of the coordination number (C.N.) from six to seven or eight, while keeping the hexadentate coordination mode of the ligand. Further increase of the metal ion size leads to the loss of the chelating properties of the diamine and formation of a bis-tridentate complex. Associated with it is the change in the binding mode of the carboxylate groups. This forms the basis for classification of divalent metal 1,3-pdta complexes into five distinct structural classes. Additionally, in the present study X-ray powder diffraction and IR spectroscopy were used to distinguish the different structural types of M(II)-1,3-pdta complexes, including Ba[Ba(1,3-pdta)]center dot 2H(2)O which has been used for their preparation.

AB  - The title compound, {[CoLi2(C11H14N2O8) (H2O)3]·2H2O}n , constitutes the first example of a salt of the [M II(1,3-pdta)]2- complex (1,3-pdta is propane-1,3-diyldinitrilo-tetra-acetate) with a monopositive cation as counter-ion. Insertion of the Li+ cation could only be achieved through application of the ion-exchange column technique which, however, appeared unsuccessful with other alkali metals and the ammonium cation. The structure contains two tetra-hedrally coordinated Li+ cations, an octa-hedral [Co(1,3-pdta)]2- anion and five water mol-ecules, two of which are uncoordinated, and is built of two-dimensional layers extending parallel to the (010) lattice plane, the constituents of which are connected by the coordinate bonds. O - Hwater⋯O hydrogen bonds operate both within and between these layers. The crystal investigated belongs to the enanti-omeric space group P21 with only one () of two possible optical isomers of the [Co(1,3-pdta)]2- complex. A possible cause of enanti-omer separation during crystallization might be the rigidification and polarization of the [M(1,3-pdta)]2- core, resulting from direct coordination of Li + cations to three out of four carboxyl-ate groups constituting the 1,3-pdta ligand. The structure of (I) differs considerably from those of the other [M II(1,3-pdta)]2- complexes, in which the charge compensation is realized by means of divalent hexa-aqua complex cations. This finding demonstrates a significant structure-determining role of the counter-ions.

AB  - The ability of Mn(II) ion to form two distinctly different complexes with 1,3-propanediaminetetraacetate (1,3-pdta) ligand has been demonstrated by performing X-ray analyses of their crystalline Mg(II) salts. The two types of Mn(II) complexes have been obtained by different synthetic routes and their crystals constitute, respectively, the solid solution of the composition [Mg(H2O)6][Mg0.5Mn0.5(1,3-pd ta)] • 2H2O (1) and the ordered crystals of the composition [Mg(H2O)6][Mn(1,3-pdta)(H2O)] • 2H2O (2). In both, six- 1 and seven-coordinated 2 Mn(II) complexes the 1,3-pdta ligand acts as a hexadentate. As 2 makes the second example of the seven-coordinated 1,3-pdta complex with divalent transition metal ion, the other being the [Mg(H2O)6][Cd(1,3-pdta)(H2O)] • 2H2O (3) complex, the paper reports the results of X-ray investigations of both of these complexes at 130 K.

AB  - The trans(O6) isomer of the Ba[Co(1,3-pddadp)] • 8H2O complex (where 1,3-pddadp represents hexadentate 1,3-propanediamine-N,N′-diacetate-N,N′-di-3-propionate ion) has been prepared and characterized by X-ray crystallography. In the crystal structure the complex cations and anions are bridged by carboxylate oxygen atoms from the in-plane coordinated glycinate rings (G-rings) of [Co(1,3-pddadp)]2- and by the barium-coordinated water molecules, thus forming 1D polymeric chains, separated by infinite water tapes hydrogen bonded to the [Co(1,3-pddadp)]2- carboxylate oxygens from the out-of-plane β-alaninate rings (R-rings). Conformational analysis of the three possible geometrical isomers: trans(O5), trans(O5O6), and trans(O6) of the [Co(1,3-pddadp)]2- complex, with ligand acting as hexadentate, as well as of the corresponding complexes of Ni(II) and Cr(III) has been performed using the consistent force field (CFF) method, with the parameters developed previously for edta-type complexes of chromium(III) and supplemented with new parameters for cobalt(II) and nickel(II). The energy-minimized structure of the trans(O5O6) isomer represents the global minimum for the [M(1,3-pddadp)]n- (M = Co(II), Ni(II), and Cr(III)) species. The occurrence of the least energetically favored trans(O6) isomer in a crystal and the exceptional conformation of the axially oriented β-alaninate rings can be accounted for by the stabilizing role of the infinite tapes of planar cyclic water pentamers and hexamers which act as a "glue" to reinforce the coordination polymeric chains.

The complexes (a) and (b) form isomorphic crystals that undergo a spontaneous resolution during the crystallization process yielding either enantiopure Λ (space group P61) or Δ (space group P65) isomers. The [M(1,4-bdta)]2- (M = Co(II) (a) and Ni(II) (b)) and [Mg(H2O)6]2+ octahedra are arranged in hydrogen bonded 2D-layers. Interception of these layers results in chiral channels filled with water molecules, which together with uncoordinated carboxylate oxygens of the complex anion, form mono-spiro chain that propagates in a helical manner along the c-direction. To the best of our knowledge, this is the first report on spontaneous resolution involving 1,4-bdta ligand and one of a few reports that concern conglomerate crystallization of M(II)(N2O4) complexes. The electronic absorption spectra of [Co(1,4-bdta)]2- and [Ni(1,4-bdta)]2- are presented and discussed in comparison with those of similar complexes and with reference to the varying topologies of these complexes.
