Bioorganometallic Chemistry

Organometallic based biologically active compounds: synthesis of mono- and di-ethanolamine derived ferrocenes with antibacterial, antifungal and cytotoxic properties (p 1005-1012)

Condensation reactions of 1,1-diacetylferrocene with ethanolamine have been investigated. The obtained compounds have been further used for their ligation and biological properties with Co(II), Cu(II), Ni(II) and Zn(II) metal ions. The synthesized compounds have been screened for their antibacterial properties against pathogenic bacterial strains e.g., Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus, Salmonella typhi and for antifungal activity against Trichophyton longifusus, Condida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani and Candida glaberata using agar-well diffusion method.

A new polyester, poly-(ethylene oxamide- N, N- diacetate) (PEODA) containing glycine moiety was synthesized by the reaction of oxamide-N, N-diacetic acid and ethylene glycol and its polymer metal complexes were synthesized with transition metal ions.The polymer metal complexes showed excellent antibacterial activities against both types of microorganisms, whereas the polymeric ligand also found to be effective but respectively least to the polymer metal complexes.

In vitro effects of methylmercury on ascidian (Styela plicata) immunocyte responses (p 1022-1028)

Methylmercury1 sublethal concentra- tions affect innate immune responses of Styela plicata hemocytes. The phenoloxidase-dependent hemocyte cytotoxic activity toward erythrocytes, due to quinone products, as well as the phagocytic activity vs yeast are decreased. Both the responses need cell-target contacts that could be affected by methylmercury which causes changes in hemocyte shape and spreading capacity as revealed by a microplate method. The hemocyte immune responses and the micropalte test could be an additional immunotoxicology test for marine environment evaluation.

Two binuclear MoS complexes have been prepared by the reaction of (NH4)2MoS4 and amino acids L (L = glycine, nitrilotriacetic acid) in ethanol-water medium at ambient temperature. They were characterized by spectroscopic analyses and by X-ray crystallography. The molybdenum atom is hexa-coordinated in each case, surrounded by two bridging sulfurs, one terminal oxygen atom as well as a nitrogen atom and two oxygen atoms from the ligands. Their catalytic activities in the reduction from C2H2 to C2H4 as well as other binuclear MoSpolycarboxylate complexes, a [Fe4S4] single cubane and a chainlike MoFeS compound have been described.

Synthesis and reactivity of thiophene palladium and thiophene dipalladium complexes with unsaturated molecules (p 1041-1053)

DOI: 10.1002/aoc.1329

 

Thiophene monopalladium(II) 2a, b and thiophene dipalladium complexes 3a, b were formed by the reaction of bulky 2,5-dibromothiophene with molar amounts of [Pd2(dba)3]·dba [Pd(dba)2] in the presence of a stoichiometric amount of nitrogen donor ligands such as bpy or dtbbpy with equimolar ratio in degassed acetone under nitrogen. The complexes 2a, b and 3a, b were examined by insertion reactions with CO or a different molar amount of bulky isocyanides such as CNXy (Xy = 2,6-Me2C6H3), as shown by palladium(II) complexes 8 and 11. On the other hand, the treatment of complexes 2a, b and 3a, b with TlOTf (Tf = CF3SO2) in CH2Cl2 gave the cyclopalladate cation or palladocycle of 9a, b and 12a, b.

Synthesis, crystal structure and magnetic property of a novel ion-pair nickel(III) complex containing 1,2-benzenedithiolate (p 1054-1058)
Guang-Xiang Liu, Liang-Fang Huang, Xiao-Ming Ren
Published Online: Nov 20 2007 3:29AM
DOI: 10.1002/aoc.1334

 

A new ion-pair complex, [NO2BzPy][Ni (bdt)2] (1), was synthesized and characterized. The X-ray structure analysis shows that the anions are centrosymmetric and the two non-equivalent anions form different uniform-spaced stacking pattern. The temperature dependence of magnetic susceptibilities of 1 indicate ferromagnetic behavior in the antiferromagnetic exchange system, which may arise from spin-canting.

Synthesis, structural characterization and catalytic activities of dicopper(II) complexes derived from tridentate pyrazole-based N2O ligands (p 1059-1065)

DOI: 10.1002/aoc.1336

 

A series of dicopper(II) complexes derived from pyrazole-containing N2O ligands were synthesized and three of them characterized by single-crystal X-ray diffraction analysis. Each compound has one inversion center located the middle of the Cu2O2 plane. Two of the compounds were investigated on their oxidation of 3,5-di-tert-butylcatechol in anaerobic conditions for modeling the function of catechol oxidase.
