Synthesis and molecular structure of arene ruthenium(II) benzhydrazone complexes: Impact of substitution at the chelating ligand and arene moiety on antiproliferative activity

A convenient method for the synthesis of ruthenium(ii) arene benzhydrazone complexes (1-6) of the general formula [(eta6-arene)Ru(L)Cl] (arene-benzene or p-cymene; l-monobasic bidentate substituted indole-3-carboxaldehye benzhydrazone derivatives) has been described. The complexes have been fully characterized via elemental analysis, IR, UV-vis, NMR and ESI-MS spectral methods. The solid-state molecular structures of the representative complexes were determined using a single-crystal X-ray diffraction study and the results indicated the presence of a pseudo octahedral (piano stool) geometry. All the complexes were thoroughly screened for their cytotoxicity against human cervical cancer cells (HeLa), human breast cancer cell line (MDA-MB-231) and human liver carcinoma cells (Hep G2) under in vitro conditions. Interestingly, the cytotoxic activity of complexes 3, 4 and 6 is much more potent than cis-platin with low IC50 values against all the cancer cell lines tested. Furthermore, the mode of cell death in the MDA-MB-231 cells was assessed via AO-EB staining, Hoechst 33258 staining, flow cytometry and comet assay. Furthermore, the results of Western blot analyses suggest that complexes 3 and 6 accumulate preferentially in the mitochondria of MDA-MB-231 cells and induce apoptosis via mitochondrial pathways by up-regulating p53 and Bax, and down-regulating Bcl-2.

Chemical and light-driven oxidation of water catalyzed by an efficient dinuclear ruthenium complex

Near-IR phosphorescent ruthenium(II) and iridium(III) perylene bisimide metal complexes

The phosphorescence emission of perylene bisimide derivatives has been rarely reported. Two novel ruthenium(II) and iridium(III) complexes of an azabenz-annulated perylene bisimide (ab-PBI), [Ru(bpy)2(ab-PBI)][PF6]2 1 and [CpIr-(ab-PBI)Cl]PF6 2 are now presented that both show NIR phosphorescence between 750-1000 nm in solution at room temperature. For an NIR emitter, the ruthenium complex 1 displays an unusually high quantum yield (Fp) of 11% with a lifetime (tp) of 4.2 ms, while iridium complex 2 exhibits Fp < 1% and tp =33 ms. 1 and 2 are the first PBI-metal complexes in which the spin-orbit coupling is strong enough to facilitate not only the Sn?Tn intersystem crossing of the PBI dye, but also the radiative T1?S0 transition, that is, phosphorescence. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.COA of Formula: C20H16Cl2N4Ru.

Reactions of the Lithiated Diphosphine tBu2P?P(SiMe3)Li with [(eta6-C6H6)RuCl2]2in the Presence of Tertiary Phosphines

tBu2P?P(SiMe3)Li reacted with [(eta6-C6H6)RuCl2]2at ?40 C in the presence of PR3(PR3= PEt3, PEt2Ph, PEtPh2) by the nucleophilic addition of the tBu2P?P(SiMe3) moiety to the benzene ring to yield solely the complexes [(R3P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1). These products decomposed slowly at ambient temperature to yield benzene, Ru clusters, and small amounts of the dinuclear ruthenium complexes [{(R3P)2Ru}2(mu,eta2:2-P2)2Ru(PR3)2] (Ru?Ru) (6). Single-crystal X-ray diffraction studies of [(PhEt2P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1b) and [(Ph2EtP)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1c) revealed that the addition of the tBu2P?P(SiMe3) group occurred through an exo pathway. Complex 6a (R = Et) displays a planar rectangular P4system consisting of two P2units and a Ru?Ru distance that lies in the range of a single bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 37366-09-9, you can also check out more blogs about37366-09-9

New ruthenium(II)-letrozole complexes as anticancer therapeutics

Novel ruthenium-letrozole complexes have been prepared, and cell viability of two human cancer cell types (breast and glioblastoma) was determined. Some ruthenium compounds are known for their cytotoxicity to cancer cells, whereas letrozole is an aromatase inhibitor administered after surgery to post-menopausal women with hormonally responsive breast cancer. A significant in vitro activity was established for complex 5¡¤Let against breast cancer MCF-7 cells and significantly lower activity against glioblastoma U251N cells. The activity of 5¡¤Let was even higher than that of 4, a compound analogous to the well-known drug RAPTA-C. Results from the combination of 5¡¤Let (or 4) with 3-methyladenine (3-MA) or with curcumin, respectively, revealed that the resultant cancer cell death likely involves 5¡¤Let-induced autophagy.

A Ruthenium(II) Complex as a Luminescent Probe for DNA Mismatches and Abasic Sites

[Ru(bpy)2(BNIQ)]2+ (BNIQ = Benzo[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)22+ and [Fe(CN)6]3- implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.

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.

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.
