Abstract:

Six new complexes of palladium(II) with a general formula [Pd(L)2Cl2], where L = 2-amino-4-(4-subsistuted phenyl)thiazole. The palladium complexes were prepared by the reaction of 2-amino-4-(4-subsistuted phenyl)thiazole ligands with with Bis(benzonitrile)palladium(II) dichloride in chloroform solvent at molar ratio Pd:L=1:2. The resulting complexes were characterized by the magnetic susceptibility, conductivity measurements, infrared, 1H NMR and the thermo gravimetric analysis. Elemental analyses, spectroscopic and another physical studies of the prepared palladium (II) complexes allowed structures to be proposed. The thermal properties of the prepared complexes indicated the all-decomposition steps and gave an insight about the stability of palladium(II) complexes. The physical analysis indicated that prepared ligands behaved as mono dental, bounding Pd(II) through the nitrogen atoms from the thiazole ring.

Abstract:

The manuscript describes the binding of DNA as well as biological studies of some mixed ligand dithiocarbamate Palladium (II) complexes (1-5). The observed compounds are of general formulae [PdCl(DT)(PR3)]. The dithiocarbamate “DT” and “PR3” groups are varied among the studied complexes as DT = bis[(2-methoxyethyl) dithiocarbamate)] (1 and 2), dibutyl dithiocarbamate (4 and 5), bis[(2-ethyl) hexyl dithiocarbamate)] (3); PR3 = triphenyl phosphine (1), benzy diphenyl phosphine (2), diphenyl-tert-butyl phpsphine (3), diphenyl-p-tolyl phosphine (4) and diphenyl-2-methoxy phenyl phosphine (5). The synthesized complexes were screened for DNA binding study via (UV Visible spectrophotometry and Viscometery) and biological activities such as anti-bacterial and anti-fungal, Molinspiration calculations and antioxidant potencies stimulated by hydrogen peroxide in human blood lymphocytes. In case of drug DNA interaction, complexes showed some sort of interaction with DNA solution. Almost all the complexes exhibited moderate antifungal and antibacterial behavior (against Gram positive and negative bacterial strains). The Molinspiration calculation study revealed that the said Pd (II) mixed complexes are biologically significant drugs having adequate molecular properties regarding drug likeness, except the log P values of complexes 3-5 because some structural adjustments must be done for enhancement of their bioavailability and hydrophilic nature. Regarding the antioxidant potential of complexes 1, 2 and 4, the H2O2 treatment of complexes violently decreased the action of antioxidant enzymes, superoxide dismutase and catalase and enhanced the level of thiobarbituric acid-reacting substances. Under experimental conditions, we conclude that all complexes act as anti-mutagens as they significantly suppress H2O2-induced oxidative damage at non-genotoxic concentrations.

Abstract:

Introduction. Infectious diseases remain a serious threat to humanity worldwide as bacterial pathogens grow more diverse. Bacteria, fungi, and parasites develop resistance to clinically approved antimicrobials, which reduces the efficacy of available drugs and treatment measures. As a result, there is an ever growing demand for new highly effective pharmaceuticals. This review describes mono- and polynuclear platinum and palladium complexes with antimicrobial properties. We compared several groups of antibacterial agents: antibiotics, antioxidant biologically active substances, antimicrobial nanoparticles, nanocomposite materials, biopolymers, micellar systems, and plant extracts. Study objects and methods. The review covered relevant articles published in Web of Science, Scopus, and Russian Science Citation Index for the last decade. The list of descriptors included such terms as mononuclear and binuclear complexes of platinum, palladium, and antimicrobial activity. Results and discussion. Chelates of platinum, palladium, silver, iridium, rhodium, ruthenium, cobalt, and nickel are popular therapeutic agents. Their antimicrobial activity against pathogenic microorganisms can be enhanced by increasing their bioavailability. Metalbased drugs facilitate the transport of organic ligands towards the bacterial cell. The nature of the ligand and its coordination change the thermodynamic stability, kinetic lability, and lipophilic properties of the complex, as well as the reactivity of the central atom. Polynuclear platinum and palladium complexes contain two or more bound metal (coordinate) centers. Covalent bonding with bacterial DNA enables them to form a type of DNA adducts, which is completely different from that of mononuclear complexes. Conclusion. Metal-based drugs with functional monodentate ligands exhibit a greater antimicrobial effect compared to free ligands. Poly- and heteronuclear complexes can increase the number of active centers that block the action of bacterial cells. When combined with other antibacterial agents, they provide a synergistic effect, which makes them a promising subject of further research.

Abstract:

In the context of palladium-catalyzed guanylation of anilines herein, we have been able to characterize and isolate bis(anilino) and bis(guanidino)Pd(II) complexes using reaction conditions under which stoichiometric amounts of palladium salts are used. Characterization of these palladium complexes strongly supports a mechanistic proposal for the catalytic guanylation of anilines using PdCl2(NCCH3)2 as catalyst that involves the intermediacy of these Pd(II) complexes.

Abstract:

Cyclometallated µ-halogeno dimers derived from nitrogen donor ligands (1-phenylpyrazoles, 2-phenylpyridine, and 1-(2′-pyridyl)indole) were treated with unidentate nitrogen and phosphorus donor ligands to give a series of neutral monomeric palladium(II) and platinum(II) complexes. An initial prescreen of the complexes against the mouse lymphoid leukæmia cell line L1210 indicated that the complexes exhibited growth inhibitory activity over a relatively wide concentration range. Two factors that gave rise to increased activity were steric hindrance about the metal centre resulting from hindered ligands such as 2,6-dimethylpyridine, or the presence of a phosphorus donor ligand. Little correlation between palladium and platinum complexes was noted. Four complexes were selected for further in vivo study and, while none of the palladium complexes showed more than marginal activity against P388 leukæmia at doses below toxic levels, one platinum complex with a hindered metal centre did display significant antitumour activity against this model.Key words: cyclometallation, palladium, platinum, cytotoxicity, anticancer.

Abstract:

In palladium refining technologies, as well as in some analytical procedures, complexes of bivalent palladium with diimines, amines, oximes, thiourea, and other compounds are used. In the technologies used, complex compounds of palladium are subjected to thermal decomposition, during which metallic palladium is formed. The precious metals market is seeing a rapid rise in the price of palladium on the back of a rapid increase in demand for it. It has been experimentally shown that active decomposition of dichlorodiamminepalladium Pd(NH3)2Cl2 and dimethylglyoximpalladium (C4H7N2O2)2Pd occurs at temperatures of 200…250 °C. Only the diffraction maxima of palladium were observed on the X-ray diffraction patterns of samples that underwent heat treatment at 900 °C and above. At these temperatures, palladium oxide is not stable. At temperatures around 500 °C, the samples are almost completely oxidized; there are no reflections of palladium on the diffraction patterns.

Abstract:

The study aims to synthesize and examine the biological activity of mono- and binuclear platinum (II) and palladium (II) complexes containing terminal and bridging nitrite ligands against the test cultures of Bacillus subtilis B4647, Aspergillus brasiliensis (niger) F679, Pseudomonas aeruginosa B8243, and Escherichia coli. Through the interaction of mononuclear platinum (II) and palladium (II) complexes, dimeric complexes having nitrite ligands were synthesized. The composition and structure of these complexes were established using elemental analysis, conductometry, potentiometry, cryoscopy, infrared spectroscopy, X-ray diffraction analysis, and X-ray fluorescence analysis. A way to coordinate nitrite ligands with the central atom was established. Antimicrobial and antifungal properties were evaluated according to the capability of the synthesized complexes to inhibit the activity of bacteria and fungi via diffusion in agar and in vitro dilution. The minimum inhibitory and bactericidal concentrations of the complexes suppressing the visible growth of microorganisms and fungi, as well as exhibiting their bactericidal effect, ranged from 62.5–125 μmol/dm3. The obtained results revealed a high activity of the palladium (II) binuclear complex of the non-electrolytic type and the platinum (II) binuclear complex of the cationic type. Unlike mononuclear complexes, palladium and platinum binuclear complexes demonstrate higher antibacterial activity. Antibacterial effectiveness exhibited by the palladium complex of the non-electrolytic type against bacteria Bacillus subtilis and Escherichia coli, as well as fungi Aspergillus niger, is more pronounced. The only exception is the antimicrobial activity of the palladium complex against Pseudomonas aeruginosa, which is comparable to that of the binuclear platinum complex of the cationic type. By changing the structure of the complex, the composition and charge of the inner sphere, the number of coordination centers, as well as the nature and denticity of ligands, it is possible to achieve a higher toxic effect of the complexes against bacteria and fungi.

Direct arylation is an atom-economical alternative to more established procedures such as Stille, Suzuki or Negishi arylation reactions. In comparison with other palladium sources and ligands, the use of palladium pincer complexes as catalysts or pre-catalysts for direct arylation has resulted in improved efficiency, higher reaction yields, and advantageous reaction conditions. In addition to a revision of the literature concerning intra- and intermolecular direct arylation reactions performed in the presence of palladium pincer complexes, the role of these remarkably active catalysts will also be discussed.

The spectroscopically predicted structure of the obtained palladium(II) complex was confirmed by X-ray analysis. Singe crystals suitable for X-ray measurements were obtained by slow crystallization from a DMSO-water mixture. Cytotoxic effects of platinum(IV), palladium(II) complexes and cisplatin on the 4T1 and B16F1 cell lines were determined using the MTT colorimetric technique. The complexes showed a dose dependence on cytotoxic effect toward both cell lines. Both complexes were less active than cisplatin, the exception was concentrations above 62.5 μM of platinum(IV) complex in the B16F1 cell line.

Abstract:

Square planar complexes of palladium(II) were prepared by the reaction of PdCl2 with four different thio Schiff bases, namely 2-acetyl-pyridine S-benzyl dithiocarbazate (L1H), 2-acetylthiophene-S-benzyl dithiocarbazate (L2H), 2-acetylfuran-S-benzyl dithiocarbazate (L3H) and 2- acetylnaphthalene-S-benzyl dithiocarbazate (L4H) in a 1:2 molar ratio. Elemental analysis, molecular weight determinations, conductance measurements and spectral data, including electronic, IR, 1H and 13C NMR and X-ray powder diffraction studies, confirmed the formation of palladium(II) complexes. The electrochemical behaviour of one of the palladium(II) complex has also been determined by cyclic voltammetry. The antimicrobial activities of the Schiff base ligands and their corresponding palladium(II) complexes have been tested in vitro against various pathogenic bacterial and fungal strains. The cytotoxicity of [Pd(L1)2] complex shows the promising results when analyzed using MTT cell proliferation assay.

Abstract:

The results of cytotoxicity cis-diamine mono- and binuclear complexes of platinum(II) and palladium(II) are presented. The cytotoxicity was investigated by the method of biotesting with Paramecium caudatum and by MTT-assay with human cells: epidermoid carcinoma A431 and minimal transformed aneuploid keratinocytes HaCaT. Cytotoxicity of complexes towards protists is higher than against human cells, however, comparatively, HaCaT is more sensitive than A431 by the treatment all complexes. It is noted that cytotoxicity of palladium(II) complexes is higher than the analogues with platinum(II).

Abstract:

The palladium complexes [Pd(PPh3)(aryl)LOR] (aryl = Ph, p-tolyl; LOR¯ = [(C5H5)Co{P(OR)2O}3]¯, R = Me, Pri) have been prepared by reaction of [PdI(aryl)(tmeda)] (tmeda = N,N,N′,N′-tetramethyl-ethylenediamine) with the silver salts AgLOR in the presence of PPh3. The complexes [Pd(PPh3)(aryl)LOR] rapidly and reversibly insert carbon monoxide to yield the aroyl palladium complexes [Pd(PPh3)(C(O)- p-tolyl)LOR] (R = Me, Pri ). The palladium iodide complex [PdI(p-tolyl)(tmeda)] and the silver salt AgLOR in the absence of PPh3 form an unusual adduct [(p-tolyl)(tmeda)Pd(µ2-I)AgLOMe] that contains a short silver-iodide bond (Ag-I 2 · 703(1) Å). The silver-palladium bond is bridged by iodine (Pd-Ag 3 · 011(1), Pd{I 2 · 5934(9) Å) and the silver atom is coordinated by the tris-chelating oxygen ligand LOMe.

Abstract:

Palladium(II) complexes of aromatic hemiporphyrazines were prepared by the reaction of bis(dibenzylideneacetone)palladium(0) with the corresponding metal-free macrocycles. Single crystal X-ray analysis revealed that a palladium(II) ion was coordinated inside the macrocyclic cavity to form two Pd – C bonds. Electronic properties of the metalloorganic compounds were characterized by NMR, UV-vis-NIR, and magnetic circular dichroism (MCD) spectroscopy.

Abstract:

A selection of 1 : 1 (palladium/ligand) complexes of cyclam derivatives incorporating from one to three N-benzyl groups has been synthesized. Related 3 : 1 species of two symmetrically branched, tri-cyclam species incorporating 1,3,5-‘tribenzyl’ or phloroglucinol cores are also reported. The X-ray crystal structures of the palladium complexes of two isomeric forms of the N,N′-dibenzylated (single-ring) macrocycle have been determined. In each complex the palladium ion occupies the N4-plane of the respective macrocycles in a square planar arrangement, with each complex cation adopting a stable trans-III configuration.
