Rationally designed curcumin based ruthenium(ii) antimicrobials effective against drug-resistant: Staphylococcus aureus

Two new curcumin containing octahedral ruthenium(ii) polypyridyl complexes, viz. [Ru(NN)2(cur)](PF6) [NN = bpy (1), phen (2)], were designed to explore the antimicrobial activity against ESKAPE pathogens, especially with the Gram-positive drug resistant S. aureus. Solid-state structural characterization by single-crystal X-ray crystallography shows the RuII-center in a distorted octahedral {RuN4O2} geometry. The tested compounds showed significant inhibitory activity and high selectivity (MIC = 1 mug mL-1, SI = 80) against a wide variety of methicillin and vancomycin-resistant S. aureus strains. Compound 1 exhibited strong anti-biofilm activity (48% reduction of biofilm) at 10¡Á MIC compared to the other approved drugs. The murine model of Staphylococcus infection significantly reduced the mean bacterial counts when treated with complex 1 compared to vancomycin, demonstrating its antimicrobial potential in vivo.

Reaction of trans-[RuNO(NH3)4(OH)]Cl2 with nitric acid and synthesis of ammine(nitrato)nitrosoruthenium complexes

The reaction of trans-[RuNO(NH3)4(OH)]Cl2 with nitric acid has been studied. Reaction prod- ucts have been identified by IR spectroscopy, NMR, mass spectrometry, powder and single-crystal X-ray dif- fraction, and chemical analysis. Synthesis methods have been developed for amminenitrosoruthenium com- plexes containing outer-sphere and coordinated nitrate ions: trans-[RuNO(NH3)4(H2O)](NO 3)3 (I), trans- [RuNO(NH3)4(NO 3)](NO3)2 (II), and fac-[RuNO(NH 3)2(NO3)3] (III). Complex II has two polymorphs: monoclinic and tetragonal. The latter has been studied by X-ray crystallography. Pleiades Publishing, Ltd., 2012.

Synthesis and dynamic behavior of an anthyridine-ligated ruthenium complex

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)2](PF6)2 ([1](PF6)2; L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2?-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1 ](PF6)2 was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)( CH3CN)(bpy)2](PF6)2 ([2]( PF6)2), was formed. X-ray crystallographic data revealed that, in [2](PF6)2, L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)2 shows a unique haptotropic rearrangement in an acetonitrile solution.

Study of half-sandwich platinum group metal complexes bearing dpt-NH2 ligand

A quite general approach for the preparation of eta5-and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, C10H14 and C6Me6) and eta5-pentamethylcyclopentadienyl rhodium and iridium complexes [(eta6-C5Me5)M(mu-Cl)Cl]2 (M = Rh, Ir) react with 2 equiv. of 4-amino-3,5-di-pyridyltriazole (dpt-NH2) in presence of NH4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(dpt-NH2)Cl]PF6 {arene = C10H14 (1), C6H6 (2) and C6Me6 (3)} and [(eta6-C5Me5)M(dpt-NH2)Cl]PF6 {M = Rh (4), Ir (5)}. However, the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3)2Cl], [(eta5-C5H5)Os(PPh3)2Br], [(eta5-C5Me5)Ru(PPh3)2Cl] and [(eta5-C9H7)Ru(PPh3)2Cl] complexes react in presence of 1 equiv. of dpt-NH2 and 1 equiv. of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(dpt-NH2)]PF6 (6), [(eta5-C5H5)Os(PPh3)(dpt-NH2)]PF6 (7), [(eta5-C5Me5)Ru(PPh3)(dpt-NH2)]PF6 (8) and [(eta5-C9H7)Ru(PPh3)(dpt-NH2)]PF6 (9), respectively. These compounds have been totally characterized by IR, NMR and mass spectrometry. The molecular structures of 4 and 6 have been established by single crystal X-ray diffraction and some of the representative complexes have also been studied by UV-Vis spectroscopy.

Synthesis and characterization of organic dyes containing 4,5-diazafluorene as efficient sensitizers for dye-sensitized solar cells

Two dyes which are 4,5-diazafluoren-9-one-derived diimine ligands and their corresponding Ru(II) bipyridine complexes were synthesized. The structures of all compounds were determined by FTIR, UV?Vis, 1H-NMR, 1C-NMR, and MS spectroscopic data. The photovoltaic and electrochemical properties of these compounds were investigated and the applicability in DSSCs as photosensitizers was studied. The photovoltaic cell efficiencies (PCE) of the devices were 0.36?1.26% under simulated AM 1.5 solar irradiation of 100?mW/cm2, and the highest open-circuit voltage (Voc) reached 0.34?V. When comparing the photovoltaic performance of DSSC devices, efficiency increases L2?Product Details of 15746-57-3. Thanks for taking the time to read the blog about 15746-57-3

Synthesis, characterization and olefin metathesis studies of a family of ruthenium phosphonium alkylidene complexes

The synthesis of four ruthenium phosphonium alkylidene complexes [(H2IMes)Cl2Ru{double bond, long}CH(PCy3)]+[A]- (1, A = B(C6F5)4; 2, A = BF4; 3, A = OTf; 4, A = BPh4), differing only in the anion is described. The X-ray structures of 1, 3 and 4 show them to be isostructural in the cation, with no interaction between the Ru centers and the anion. Ring closing metathesis of a substrate to a six-membered methylcyclohexene at 0 C in CD2Cl2 using 1 mol% catalyst, shows that catalysts 1-4 behave very similarly, and exhibit superior activity in comparison to Grubbs second generation and fast-initiating catalysts.

Synthesis and glycosidase-inhibitory activity of novel polyhydroxylated quinolizidines derived from d-glycals

A number of structurally novel polyhydroxylated quinolizidines have been prepared starting from 2-deoxyglycosylamines which in turn were derived from d-glycals by following a methodology developed in our laboratory. In our strategy, Grignard reaction and ring-closing metathesis (RCM) reactions are the key steps to construct the desired skeletons. All synthesized final molecules were checked for glycosidase inhibition activity, and some were found to be selective for certain glycosidases.

Thiophenolato-bridged dinuclear arene ruthenium complexes: A new family of highly cytotoxic anticancer agents

New cationic diruthenium complexes of the type [(arene)2Ru 2(SPh)3]+, arene being C6H 6, p-iPrC6H4Me, C6Me 6, C6H5R, where R = (CH2) nOC(O)C6H4-p-O(CH2) 6CH3 or (CH2)nOC(O)CHCHC 6H4-p-OCH3 and n = 2 or 4, are obtained from the reaction of the corresponding precursor [(arene)RuCl2] 2 and thiophenol and isolated as their chloride salts. The complexes have been fully characterised by spectroscopic methods and the solid state structure of [(C6H6)2Ru2(SPh) 3]+, crystallised as the hexafluorophosphate salt, has been established by single crystal X-ray diffraction. The complexes are highly cytotoxic against human ovarian cancer cells (cell lines A2780 and A2780cisR), with the IC50 values being in the submicromolar range. In comparison the analogous trishydroxythiophenolato compounds [(arene)2Ru 2(S-p-C6H4OH)3]Cl (IC50 values around 100 muM) are much less cytotoxic. Thus, it would appear that the increased antiproliferative effect of the arene ruthenium complexes is due to the presence of the phenyl or toluyl substituents at the three thiolato bridges.
