AB  - We have synthesized and characterized Co(II) (1), Zn(II) (2), Fe(III) (3) and Cu(II) (4) complexes of 2,2'‐[2,6‐pyridinediylbis(ethylidyne‐1‐hydrazinyl‐2‐ylidene)]bis[N,N,N‐trimethyl‐2‐oxoethanaminium] dichloride (H2LCl2) by NMR, IR, and X‐Band EPR spectroscopy, respectively, as well as by single‐crystal X‐ray structural analysis. H2LCl2 belongs to the class of diacetylpyridine bis(hydrazone) ligands and bears two positively charged quaternary ammonium functionalities. The complexes 1–3 possess a pentagonal‐bipyramidal geometry, whereas 4 has square‐pyramidal geometry. Redox reactivity and SOD activity of the complexes was studied by means of electrochemical measurements in aqueous‐buffer and DMF or DMSO solutions, respectively, as well as by stopped‐flow measurements. Complexes 1–3 do not have SOD activity, whereas 4 exhibits a high catalytic rate constant for the superoxide dismutation, kcat = 1.73 × 107 m–1 s–1 (in MOPS buffer solution of pH = 7.4). The results were discussed in terms of complex redox potentials, electrostatic interactions and their spatial distribution, kinetic lability of metal centers, and stability of peroxo intermediates, respectively.

AB  - In order to improve antimicrobial effects of previously studied meso-tetrakis(4-ferrocenylphenyl)porphyrin 1, we have modified its structure by replacing two trans-positioned ferrocenylphenyl moieties with methoxy methylene substituted tert-butylphenyl moieties. Newly synthesized 5(4),15(4)-bis-(ferrocenyl)-10(4),20(4)-bis-(tert-butyl)10(2),10(6),20(2),20(6)-tetrakis-(methoxy-methylene)-5,10,15,20-tetraphenylporphyrin 4 was chemically characterized in detail (by NMR, UV/Vis, IR, MALDI-TOF and ESI MS spectrometry, cyclic voltammetry, prediction of the relative lipophilicity as well as computational methods) and its biological effects were studied in terms of its antibacterial and antifungal activity (both with and without photoactivation), cytotoxicity, hemolysis and DNA cleavage. New ferrocene bearing porphyrin 4 has demonstrated a broader antimicrobial spectrum and modified effects on eukaryotic cells compared to 1. This was discussed in terms of its i) increased lipophilicity, while exhibiting.lower toxicity, and ii) the redox potential of a two-electron process that is shifted to lower values, in comparison to ferrocene, thus, entering the physiologically available range and being activated towards redox interactions with biomolecules.

AB  - Ferrocene-substituted porphyrin RL-91 exhibits antifungal activity against opportune human pathogen Candida albicans. RL-91 efficiently inhibits growth of both planktonic C albicans cells and cells within biofilms without photoactivation. The minimal inhibitory concentration for plankton form (PMIC) was established to be 100 mu g/mL and the same concentration killed 80% of sessile cells in the mature biofilm (SMIC80). Furthermore PMIC of RL-91 efficiently prevents C albicans biofilm formation. RL-91 is cytotoxic for human fibroblasts in vitro in concentration of 10 mu g/mL, however it does not cause hemolysis in concentrations of up to 50 mu g/mL. These findings open possibility for application of RL-91 as an antifungal agent for external antibiofilm treatment of medical devices as well as a scaffold for further development of porphyrin based systemic antifungals.

AB  - The synthesis of a novel ligand 2'-[1-(2-pyridinyl)-ethylidene]-oxamohydrazide (Hapsox), from a series of 2-acetylpyridine acylhydrazones, and its complex with Co(III), which is the first in this series of complexes are described. Both the ligand and the complex were characterized by elemental analysis, IR, H-1-NMR, and C-13-NMR spectra, and the structure of the complex [Co(apsox)(2)]ClO4 was determined by X-ray structural analysis. It was established that [Co(apsox)(2)]ClO4 has an octahedral geometry with two tridentate apsox ligands in monoanionic form. Structural characteristics, lengths of the bonds, and angles between the bonds were typical for Co(III) complexes of distorted octahedral geometry. Both direct and template synthesis afforded the same geometrical isomer of the complex with two apsox ligands meridionally bound to the central metal ion, even in the case when equimolar quantities of Co(ClO4)(2) and Hapsox were applied.

AB  - The synthesis of two Fe(III) complexes with a doubly deprotonated polydentate of the acylhydrazone class is described. The first complex was obtained by hydrolyzing the previously synthesized high-spin pentagonal-bipyramidal (PBP) [Fe(Hdapsox)Cl-2] (H(2)dapsox = 2',2"'-(2,6-pyridindiyldiethylidene)dioxamohydrazide); the second was obtained by a template synthesis in a base medium starting from iron(III) chloride, 2,6-diacetylpyridine (dap) and semioxamazide (sox) (in a 1:1:2 molar ratio). Hydrolysis, during which the semioxamazide amide group changed into a carboxyl group, resulted in the mu -oxo-diiron(III) complex [Fe(dapoamh)(H2O)(2)O . 3H(2)O (H(2)dapoamh = dioxo-2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene)diacetic acid) with a doubly deprotonated acylhydrazone that retained its PBP geometry. The [Fe(dapsox)Cl].H2O complex obtained in the latter case has a square-pyramidal geometry with an asymmetrically coordinated, but still doubly deprotonated dapsox as a tetradentate. The structure of the [Fe(dapoamh)(H2O)(2)O . 3H(2)O complex determined by single-crystal X-ray analysis in this work represents the first mu -oxo-dimer of a PBP geometry with an acyclic polydentate. This is also the first diamagnetic Cl-oxo-diiron(III) complex ever obtained; this not only points to the super-exchange interaction over an ore-oxygen, but also to a significant interaction between the two low-spin Fe(III) ion d-orbitals. Based on the EPR spectra, it has been established that the monomer [Fe(dapsox)Cl].H2O complex is among the rare Fe(III) complexes with an intermediate spin state S = 3/2, and that a temperature decrease causes it to change to a low-spin complex, i.e. it demonstrates a cross-over (S = 3/2 reversible arrow S = 1/2). Further characterization has been done by IR and UV-VIS spectroscopy, and also by measuring the magnetic momentum at 293, 195 and 77 K. The results of this work, as well as of the previously synthesized Cu(II), Co(II) and Ni(II) complexes with H(2)dapsox, Hdapsox(-) and dapsox(2-), have led us to the conclusion that the doubly deprotonated acylhydrazone ligand has a considerably stronger field than its neutral or monoanionic forms.

This is also the first diamagnetic Cl-oxo-diiron(III) complex ever obtained; this not only points to the super-exchange interaction over an ore-oxygen, but also to a significant interaction between the two low-spin Fe(III) ion d-orbitals. Based on the EPR spectra, it has been established that the monomer [Fe(dapsox)Cl].H2O complex is among the rare Fe(III) complexes with an intermediate spin state S = 3/2, and that a temperature decrease causes it to change to a low-spin complex, i.e. it demonstrates a cross-over (S = 3/2 reversible arrow S = 1/2). Further characterization has been done by IR and UV-VIS spectroscopy, and also by measuring the magnetic momentum at 293, 195 and 77 K. The results of this work, as well as of the previously synthesized Cu(II), Co(II) and Ni(II) complexes with H(2)dapsox, Hdapsox(-) and dapsox(2-), have led us to the conclusion that the doubly deprotonated acylhydrazone ligand has a considerably stronger field than its neutral or monoanionic forms.

AB  - In a template synthesis from ethanolic solution of MoOCl3, 2,6-diacetylpyridine (dap), and semioxamazide (sox), in the molar ratio 1:1:2, a dimeric molybdenum(V) complex [Mo2O2(H(2)dapsox)(2)]Cl-6 . 4H(2)O (where H(2)dapsox= 2 ' ,2 ' ' '-(2,6-pyridinediyldiethylidenedioxamohydrazide) was obtained. In a similar reaction, starting from La(NO3)(3) . 6H(2)O, the complex [La(H(2)dapsox)(NO3)x](NO3)(3-x).1/2EtOH (x=1,2), having coordination number 9, was obtained. In the latter complex two NO3 groups were bidentately coordinated in the solid state, but only one in the solution. Besides [Mo2O2(TPP)(2)] (TPP = tetraphenylporphyrin), the molybdenum(v) complex [Mo2O2 (H(2)dapsox)(2)]Cl-6 . 4H(2)O is the only other known example of a dimeric mu -oxodimolybdenum(V) species that is paramagnetic (mu = 0.95 BM). One of the Mo atoms has pentagonal bipyramidal coordination, and the other pentagonal pyramidal coordination. In aqueous solution a rare example of a pentagonal pyramidal ion [MoO(dapsox)](+) is presumably present. Solution EPR spectra (at 77 K) cannot be related to either of the two known types of Mo(V) species based on the extent of g anisotropy. The substances also were characterized by IR and electronic spectroscopy, and by thermal analysis.

AB  - Starting from Cu(II) and Ni(II) perchlorate and Fe(III) chloride in the presence of 2,6-diacetylpyridine (dap) and semioxamazide (sox), the [Cu(Hdapsox)H2O]ClO4 (I), [Ni(Hdapsox)(MeOH)(2)]ClO4 (II) and [Fe(Hdapsox)Cl-2]. 1/2H(2)O (III) complexes with a singly deprotonated ligand Hdapsox(-) of the acyl hydrazone class (with H(2)dapsox = 2',2'''-(2,6-pyridindiyldiethylidene)dioxamohydrazide) have been obtained and characterized for the first time by a template synthesis. The previously assumed [1] square-pyramidal structure of the Cu(II) complex with an asymmetrical coordination of Hdapsox(-) has been confirmed by a single-crystal X-ray analysis. In II Hdapsox(-) is octahedrally coordinated around a Ni(II) ion, while III is found to be a pentagonal-bipyramidal complex with a symmetrically bonded Hdapsox(-). Causes of a ligand deprotonation occurring in a very acid medium (pH = 0) and of a different coordination pattern in the case of Cu(II), NI(II) and Fe(III) are interpreted by a d(n) configuration and an effective nuclear charge of the central metal ion (crystal field effects).
