Analysis of the electronic structure of the electron-deficient cluster cation [Ru4(eta6-C6H6) 4H4]2+ (12+)by density functional theory calculations shows a very small energy gap (0.06 eV) between the diamagnetic singlet state and the paramagnetic triplet state, as a consequence of the absence of a significant Jahn-Teller distortion in the molecular structure of 12+. Magnetic measurements of [1]Cl2, [1][BF4]2, and [1][PF6]2 show 1 2+ to be diamagnetic in the fundamental state, with some weak temperature-independent paramagnetism, depending upon the nature of the counterion.

Synthetic Route of 37366-09-9, An article , which mentions 37366-09-9, molecular formula is C12H12Cl4Ru2. The compound – Dichloro(benzene)ruthenium(II) dimer played an important role in people’s production and life.

The special ability of organometallic complexes to catalyze various transformations might offer new effective mechanisms for the treatment of cancer. Studies that report both the biological properties and the ability of metallic complexes to promote therapeutically relevant catalytic reactions are limited. Herein, we report the anticancer activity and catalytic potential of some ruthenium(II)-arene complexes bearing bidentate Schiff base ligands (2a and 2b) and their reduced analogues (5a and 5b, respectively). In comparison to their Schiff base counterparts 2a and 2b, we demonstrate that amine complexes 5a and 5b display (i) a higher in vitro antiproliferative activity on different human cancer cell lines, (ii) a lower rate of hydrolysis, and (iii) an improved initial catalytic rate for the reduction of NAD+ to NADH. In contrast to their imine analogues 2a and 2b, we also show that amine complexes 5a and 5b induce the generation of intracellular reactive oxygen species (ROS) in MCF-7 breast cancer cells. Our results highlight the impact that a simple ligand modification such as the reduction of an imine moiety can have on both the catalytic and biological activities of metal complexes. Moreover, the ruthenium complexes reported here display some antiproliferative activity against T47D breast cancer cells, known for their cis-platin resistance.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 37366-09-9, help many people in the next few years., Synthetic Route of 37366-09-9

Complexes <(eta6-arene)RuCl2> have been prepared.Easy methanolysis and hydrolysis of the ester function occur when R=t-Bu.When R=Me, the stability of the ester function allows the synthesis of the stable salts <(eta6-arene)RuCl>X (X=PF6 or BF4).Preparation of <(eta6-arene)(L)RuCl>+ (L=Me2S, MeC<*>N or t-BuC<*>N) from eta1-P- and eta2-(P,O)-methyl phosphinoacetate derivatives has been studied and the strength of both the L and ester ruthenium coordinative bonds compared.The reactivity of these functional phosphine complexes differs markedly from that of the homologous compounds <(eta6-arene)(PMe3)RuCl2>,<(eta6-arene)RuCl2> and <(eta6-arene)RuCl.Competitive and reversible coordination of dimethylsulfide and nitriles or of the ester function is observed and a change in the arene produces selectivity in the coordination of dimethylsulfide and nitriles.Key words: Ruthenium; Iron; Phosphine; Arene

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 37366-09-9, C12H12Cl4Ru2. A document type is Article, introducing its new discovery., Formula: C12H12Cl4Ru2

Synthesis of new half-sandwich ruthenium (II) complexes of the type [Ru (eta6-arene) (L)Cl] (arene = benzene or p-cymene; L = 1-pyrene-carboxaldehye benzhydrazone ligands) has been described. The synthesised complexes were completely characterised by elemental analysis and spectral (FT-IR, UV?vis, Emission, NMR and HRMS) methods. The isolated arene Ru(II) complexes are fluorescent in nature resulting the emission maxima observed in the visible region. The solid state molecular structures of the complexes 1, 2, 3 and 5 evidence that the ligands coordinate to ruthenium in a chelating kappa2 N, O- bidentate fashion, and shows the presence of typical pseudo-octahedral geometry. The potential of the complexes to act as anticancer agents are thoroughly screened on breast adenocarcinoma MCF-7, lung adenocarcinoma A549 and NIH-3T3 cell lines by in vitro experimental conditions. The anticancer activity of complex 4 is found to be remarkable towards A549 with high selectivity index and low IC50 values compared to cisplatin. The differences in biological activity of the complexes were explained on the basis of partition coefficient values and differences in the energy of ruthenium?chloride bonds. Further, AO/EB, Hoechst 33258 and flow cytometry analyses indicate that present ruthenium complexes cause cell death only via apoptosis mechanism. The DNA content in cell cycle distribution was analysed by flow cytometry which shows that complex 4 suppress the cell growth in A549 cells at sub G0/G1 phase region, indicative of apoptotic cells. This study outlines the preliminary steps towards understanding the mechanism of action with a new class of ruthenium-based chemotherapeutics.

It is now well established that ruthenium complexes are attractive alternatives to platinum-based anticancer agents. Most of the ruthenium compounds currently under investigation contain a single metal center. The synthesis of multinuclear analogues may provide access to novel complexes with enhanced biological activity. In this work, we have synthesized a set of three trinuclear complexes containing organometallic ruthenium fragments?(arene)RuCl?coordinated to a 2,4,6-tris(di2-pyridylamino)-1,3,5-triazine core [(Arene=benzene (2), p-cymene (1), or hexamethylbenzene (3)]. The interaction of the complexes with DNA was extensively studied using a variety of biophysical probes as well as by molecular docking. The complexes bind strongly to DNA with apparent binding constants ranging from 2.20 to 4.79 ×104 M?1. The binding constants from electronic absorption titrations were an order of magnitude greater. The mode of binding to the nucleic acid was not definitively determined, but the evidence pointed to some kind of non-specific electrostatic interaction. None of the complexes displayed any significant antimicrobial activity against the organisms that were studied and exhibited anticancer activity only at high (>100 muM) concentration.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Application of 37366-09-9

Application of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

Ionic liquids comprised of cationic arene-ruthenium chelate complexes and the bis(trifluoromethanesulfonyl)amide anion (=Tf2N), [(arene)RuCl(L)](Tf2N), where L = MeS(CH2)nSR (R = Me, Bu; n = 1-3), Me2N(CH2)2NMe 2 and arene = p-cymene, C6H6, have been prepared, and their thermal properties, structures, and reactivities have been investigated. These liquids undergo direct ligand exchange reactions in line with their thermal stabilities. Thermogravimetric analysis revealed that the thermal stabilities of the complexes are higher as the bridging group of the chelate ligand becomes longer. The complexes with MeSCH2SMe transform thermally into dinuclear complexes. The coordination structures were determined crystallographically.

The DNA binding of cationic complexes of the type [(eta6-arene)Ru(Aa)(dppz)] (CF3SO3)n (arene = C6H6, Me3C6H3, C6Me6; dppz = dipyrido[3,2-a:2?,3?-c]phenazine; n = 1, Aa = AcH-1cysOH 4-6; n = 2, Aa = AcmetOH 7-9; n = 3, Aa = H2metOMe 10-12) containing S-coordinated amino acids (HcysOH = L-cysteine, HmetOH = L-methionine) has been studied by UV-vis titration and 2D-NOESY. Stable intercalative binding is indicated for these complexes by their steady decrease in absorbance at maxima between 350 and 390 nm on titration with CT DNA and the bathochromic shifts of these absorption maxima. Taking 4-12 and the analogous (eta6-C6Me6)RuII complexes of the tripeptides HglyglycysOH (n = 1, 13) and HglyglymetOH (n = 2, 15; HglyOH = glycine) into account, typical DNA binding constant (Kb) ranges can be established for (eta6-arene)RuII complexes: 5.3 × 104-1.6 × 105 M-1 for monocations, 6.3 × 105 9.9 × 105 M-1 for dications and 1.6 × 106-5.5 × 106 M-1 for trications. These Kb values clearly reflect a strengthening of electrostatic interactions with the negatively charged phosphodiester backbone of DNA as the total cation charge increases. A consistent trend to higher Kb values is also apparent for the coligand series C6H6 < Me3C6H3 < C6Me6 with the relative increase being, in general, more pronounced for C6H6/Me3C6H3 pairs. The strong electronic influence of the coligand on dppz intercalation is also reflected by marked increases DeltaTm of 18.2-18.5 C in the CT DNA thermal denaturation temperature for di- and tri-cationic (eta6-C6Me6)RuII complexes. Upfield 1H NMR chemical shifts and characteristic NOE cross peaks for the dppz protons of the 1 : 1 complex formed between 9 and d(GTCGAC)2 are consistent with a side-on intercalation adjacent to T2 from the major groove.

A general electropolymerization/electro-oligomerization strategy is described for preparing spatially controlled, multicomponent films and surface assemblies having both light harvesting chromophores and water oxidation catalysts on metal oxide electrodes for applications in dye-sensitized photoelectrosynthesis cells (DSPECs). The chromophore/catalyst ratio is controlled by the number of reductive electrochemical cycles. Catalytic rate constants for water oxidation by the polymer films are similar to those for the phosphonated molecular catalyst on metal oxide electrodes, indicating that the physical properties of the catalysts are not significantly altered in the polymer films. Controlled potential electrolysis shows sustained water oxidation over multiple hours with no decrease in the catalytic current.

Four metal complexes, IL-OPPh2-Ru-p-cymene (3), IL-OPPh2-Ru-benzene (4), IL-OPPh2-Ir-Cp* (5), IL-OPPh2-Rh-COD (6), have been evaluated for in vitro antioxidant activity such as 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and reducing power activity. Maximum scavenging activity (71.43%) was obtained with IL-OPPh2-Ru-p-cymene, whereas IL-OPPh2-Rh-COD showed the highest reducing power ability. The complexes were also studied for their antimicrobial activity against three Gram-positive and three Gram-negative bacteria. In addition, DNA binding of the complexes was evaluated using calf thymus DNA. Both Ru(II) complexes exhibited good DNA-binding activity while the other complexes did not have any activity. Furthermore, ab initio quantum calculations of four complexes were also carried out using density functional theory to better understand their chemical behaviors.
