“…Silver compounds have mainly been studied for their widely known antibacterial effect; in fact, silver nitrate and certain silver complexes are still used against local infections [1][2][3]. From this perspective, compounds with Ag kernels have recently been prepared and studied, including examples containing Ag-N [4][5][6][7], Ag-O [8][9][10] and Ag-S [11][12][13][14][15] bonds and some with other additional bonds. In previous papers, we have contributed [14,15] to the study of Ag-S by preparing compounds of the type [Ag (HL)], [Ag 2 …”

Reaction of NaAuCl 4 ·H 2 O and thiodiglycol (1:3 molar ratio) with 3-(aryl)-2-sulfanylpropenoic acids, C NMR spectroscopy. The antimicrobial activities of the complexes against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Candida albicans, Pseudomonas aeruginosa and carbapenem-resistant P. aeruginosa were evaluated and compared to those of the equivalent silver(I) complexes. The comparison shows that the gold compounds generally show better activity than the silver analogues against S. aureus and B. subtilis, but low sensitivity against E. coli, P. aeruginosa and C. albicans, suggesting a different mode of antimicrobial action for equivalent silver and gold compounds.

“…The metal ion is toxic to microorganisms by poisoning respiratory enzymes and components of the electron transport system, and it also binds to the cell surface, disturbing the membrane function and replication. The base ligands of the Ag(I) complexes play the role of carrier for the Ag(I) ion to the biological system 85 . The coumarin ring has been found to have a toxic effect on microorganisms 86 .…”

Five new Cu (II), Zn (II), Pd (II), Ru (III) and Ag(I) complexes, derived from the 3‐acetylcoumarin‐2‐hydrazinobenzothiazole Schiff base (Hachbt), have been synthesized and characterized. The structures were established with the aid of elemental analyses (C, H, N), FT‐IR, 1H‐NMR, ESR, UV–visible and ESI‐mass spectra. The complexes were also investigated by magnetic susceptibility, thermal gravimetric analysis (TG‐DTA) and cyclic voltammetry measurements. The results suggest that the Schiff base ligand behaves in two different ways: neutral mono/bidentate or mono‐negative bi/tridentate. The calf thymus DNA (CT DNA) binding affinities of Hachbt and its complexes have been examined by UV–visible spectroscopy. The antifungal activity of the compounds was also screened against two fungal species of wood‐decay basidiomycetes using the agar dilution method. Different complexes caused a reduction in the fungal colony diameters at a media concentration of 100 μg/ml. The best antifungal activity was observed for the Pd (II) and Ag(I) complexes with a 60% and 79% reduction, respectively. The effect of the complexes on the ability of the same fungi to decolorize poly‐R dye on agar plates was also tested. All of the complexes showed an enhanced effect on the decolorization ability and the Cu (II) and Ru (III) complexes exhibited the strongest effect at a media concentration of 5 μg/ml. Theoretical studies were performed for all the complexes using the DFT/B3LYP/6–31 + g(d) basis set for calculations on the ligand atoms and LAN2DZ for the Pd (II) complex. The optimized geometries were found to be in a good agreement with the proposed structures. The molecular docking calculations show that the binding affinity of the Pd (II) complex is −309.170‐309.2 kcal/mol, which suggests complexation with the DNA minor groove.

“…Stabilization of the silver clusters in the matrices of various CP may be achieved by means of nitrogen- [206,207] and silver-containing ligand functional groups [208]. The strength of this interaction and the structural features of the heterocyclic ligands impart enhanced thermal stability [205,208] and luminescent properties [200,208] to these hybrid systems, while the use of thermolabile ligands such as o-sulfobenzimide and substituted ethylenediamine reduces the heat resistance of these systems [209]. New CP with 3D structure, whose macrochains consist of alternating structural fragments of two types (type A and type B), are obtained using 1,3,5-benzenetricarboxylic acid (BTA) as the ligand [210].…”

The major methods for the preparation of silver-containing polymer composite nanosystems and the formation of their hybrid structure are examined. Special attention is focused on a new class of silver-containing hybrid systems, namely, organic-inorganic coordination polymers, obtained by the self-assembly of silver complexes. The effect of intercomponent interaction on the structure and properties of these hybrid composites was examined.The creation of new improved materials is an important goal of modern chemistry and materials science. Polymer composites with hybrid structure are among such materials and hold interest since they display a combination of properties characteristic for each of the inorganic and organic components [1-3] and, in some cases, unique properties related to the specific nature of their structure [4]. From a modern viewpoint, hybrid organic-inorganic materials are formed by the combination of components, differing in their chemical nature, on a molecular or nano level through formation of chemical bonds ((non)covalent bonds, hydrogen bonding, and donor-acceptor bonds) or weaker physical bonds (van der Waals and electrostatic interactions) [5]. Special attention is given to the stability of the nanodispersed components due to interaction between the nanophase and various stabilizers [6]. The interest in silver-containing hybrid polymer composite materials, including nanocomposites, which, by their very nature, are a priori hybrid systems, is attributed to a set of properties of the matrix itself, which often possesses hybrid structure, properties of silver in ionic and nanodispersed forms, and new properties related to the appearance of hybrid silver-polymer structures [7,8]. Special interest is presently found in bionanocomposites derived from biopolymers and silver nanoparticles (SN), which display specific physicochemical properties, in particular, electrochemical, photochemical, and catalytic properties highly dependent on the dimensions and polydispersion of the nanophase [9, 10] as well as biological activity due to the ionization of the metal atoms in the presence of H 2 O/O 2 and the interaction between the SN surface and functional groups of the various biomolecules [11].In light of the important role of the polymer matrix in formation of the major structural characteristics and properties of silver-containing hybrid systems, we should classify these materials according to their chemical structure.Composites with Silver Nanoparticles (SN) Dispersed in a Polymer Matrix with Hybrid Structure. The major distinguishing feature of such materials is the prior synthesis of the hybrid polymer matrix obtained due to the formation of chemical bonds between the organic and inorganic components with subsequent introduction of SN into the system. The synthesis of the SN may be either in situ or ex situ. 740040-5760/15/5102-0074
