Ruthenium(II)?arene complexes of diimines: Effect of diimine intercalation and hydrophobicity on DNA and protein binding and cytotoxicity

A series of half-sandwich Ru(II)?arene complexes [Ru(eta6-benzene)(diimine)Cl](PF6) (1?4), where diimine is 1,10-phenanthroline (1), 5,6-dimethyl-1,10-phenanthroline (2), dipyrido[3,2-a:2?,3?-c]phenazine (3) or 11,12-dimethyldipyrido[3,2-a:2?,3?-c]phenazine (4), have been isolated and characterized using analytical and spectral methods. Complex 2 possesses a familiar pseudo-octahedral ?piano-stool? structure. The intrinsic DNA binding affinity of the complexes depends upon the diimine ligand: 3 (dppz) > 4 (11,12-dmdppz) > 2 (5,6-dmp) > 1 (phen). The pi-stacking interaction of extended planar ring of coordinated dppz (3) in between the DNA base pairs is more intimate than that of phen (1), and the incorporation of methyl groups on the dppz ring (4) discourages the stacking interaction leading to a lower DNA binding affinity for 4 than 3. Docking studies show that all the complexes bind in the major groove of DNA. Interestingly, 3 shows an ability to convert supercoiled DNA into nicked circular DNA even at 20 muM concentration beyond which complete oxidative DNA degradation is observed. The protein binding affinity of the complexes decreases in the order 4 > 3 > 2 > 1, and the higher protein binding affinity of 4 illustrates the strong involvement of methyl groups on dppz ring in hydrophobic interaction with protein. Also, 4 cleaves protein more efficiently than the other complexes in the presence of H2O2. It is notable that 2, 3 and 4 display cytotoxicity against human cervical cancer cell lines (SiHa) with potency higher than the currently used drug cisplatin. Acridine orange/ethidium bromide staining studies reveal that 3 induces apoptosis in cancer cells much more efficiently than 4.

Structural characterization and biological evaluation of a clioquinol-ruthenium complex with copper-independent antileukaemic activity

In this study, we present the synthesis, biological characterization, and first crystal structure of an organometallic-clioquinol complex. Combining ruthenium with the established apoptotic agent and 8-hydroxyquinoline derivative, clioquinol, resulted in a complex that induces caspase-dependent cell death in leukaemia cells. This activity is copper independent and is improved compared to the parent compound, clioquinol. The study of the mode of action reveals that this clioquinol-ruthenium complex does not intercalate between DNA base pairs. Additionally, this clioquinol-ruthenium complex shows proteasome-independent inhibition of the NFkappaB signalling pathway, with no effects on cell-cycle distribution. These data suggest a mechanism of action that involves a target profile that is different from that for clioquinol alone. the Partner Organisations 2014.

Effect of diphosphine ligands on ruthenium catalyzed asymmetric hydrogenation of ketones

A series of diphosphines including those that are configurationally flexible were examined in the Ru(II) catalyzed enantioselective hydrogenation of 1-acetonaphthone in the presence of a chiral diamine. These ligands were found to exert significant effects on both the activity and enantioselectivity of Ru(II)-diamine catalysts, with the ligand with the smallest bite angle yielding the lowest conversion and the one with largest bite angle yielding the lowest enantioselection.

Synthesis, characterization, anticancer and antimicrobial study of arene ruthenium(II) complexes with 1,2,4-triazole ligands containing an alpha-diimine moiety

The reaction of the ruthenium arene dimers [(eta6-arene)Ru(mu-Cl)Cl]2 (where arene=benzene or p-cymene) with the ligands 4-benzylidene-3,5-di(2?-pyridyl)-4-amino-1,2,4-triazole (L1), 2-methoxybenzylidene-3,5-di(2?-pyridyl)-4-amino-1,2,4-triazole (L2), 4-methylbenzylidene-3,5-di(2?-pyridyl)-4-amino-1,2,4-triazole (L3) and indole-3-carbaldehyde-3,5-di(2?-pyridyl)-4-amino-1,2,4-triazole (L4) in a 1:2 ratio gives the new complexes [(eta6-arene)RuCl(L)]+ [arene=C6H6 (with L=L1(1), L2(3), L4(7), with PF6- as a counter ion, and L4 (6), with Cl- as a counter ion) or p-cymene with L=L1(2), L2(4), L3(5), L4(8) with PF6- as a counter ion]. All complexes were fully characterized using 1H and 13C NMR, elemental analyses, UV/Vis and IR spectroscopy. The single crystal X-ray structures of ligand L2 and complex 1 have been determined. The structure of 1 has the Ru atom coordinated with the arene group and to the N,N?-bidentate ligand and to the Cl atom. The arene group occupies the apex, while the ligand and the Cl atom are at the base of a pseudo-octahedral three-legged piano stool. The cytotoxicity of these mononuclear complexes was established in the human epithelial colorectal adenocarcinoma cell line (Caco-2) and for selectivity in the non-cancerous human embryonic kidney cell line (HEK293), using 5-fluorouracil (5-FU) as the reference anticancer drug. Compounds 1 and 7 were relatively inactive toward the Caco-2 tumor cells (IC50>200), while complexes 2-5 showed moderate anti-proliferative properties (IC50>100-200). Compound 6, however, displayed better anti-proliferative properties with an IC50 value lower than that of the reference drug, 5-FU, and was therefore further investigated for its antimicrobial activity against six Gram-positive and four Gram-negative bacteria.

Acceptorless, neat, ruthenium-catalyzed dehydrogenative cyclization of diols to lactones

We report the dehydrogenation of 1,4-butanediol to gamma-butyrolactone catalyzed by soluble ruthenium complexes without solvent or a hydrogen acceptor. An alkylphosphine version of ruthenium bis-phosphine diamine catalysts has been prepared and was found to be the longest-lived catalyst for the conversion of 1,4-butanediol to gamma-butyrolactone. The catalytic production of gamma-butyrolactone from 1,4-butandiol with this catalyst is simple to conduct, environmentally friendly, and highly efficient.

Synthesis, antiproliferative activity and apoptosis-promoting effects of arene ruthenium(II) complexes with N, O chelating ligands

New half sandwich arene ruthenium(II) complexes of the type [Ru(arene)Cl(L)] (where arene = benzene and p-cymene, L = thiophene benzhydrazone ligands) have been synthesized from the reactions of the neutral precursor [Ru(arene) (mu-Cl) Cl]2 and the corresponding benzhydrazone ligand. All the complexes were completely characterized by elemental analysis and additionally by IR, UV?Vis, 1H NMR and ESI-MS spectroscopic methods. The solid state structures of the complexes 6 and 7 were determined by single-crystal X-ray diffraction analysis, which exhibit typical pseudo-octahedral geometry around the metal centre. The antiproliferative activity of the complexes was evaluated on cancerous (HeLa, MDA-MB-231, and Hep G2) and noncancerous (NIH3T3) cell lines. In general, complexes containing electron releasing OCH3 substituent have potential anticancer activity than those incorporating H, Cl and Br substituents. Moreover, the p-cymene complexes show more cytotoxicity than benzene derivatives, suggesting that the substituent at arene plays a vital role in the biological activity of the compounds. Further, an apoptotic mechanism of cell death in MDA-MB-231 was confirmed by AO-EB, Hoechst 33258 staining and annexin-V/PI double-staining techniques. In addition, the extent of DNA fragmentation in cancer cells was studied by comet assay.

Disilametallacycles as a platform for stabilizing M(II) and M(IV) (M = Fe, Ru) centers: Synthesis and characterization of half-sandwich complexes and their application to catalytic double silylation of alkenes and alkynes

A series of group 8 half-sandwich disilametallacycles, (eta6- arene)MII(Me2SiC6H4SiMe 2)L and (eta6-arene)MIV(H) 2(Me2SiC6H4SiMe2) (M = Fe, Ru) in the formal oxidation states of M(II) and M(IV) were synthesized and characterized. Both the M(II) and the M(IV) oxidation states were effectively stabilized by the disilametallacycle skeleton, and facile interconversion between (eta6-arene)MII-dinitrogen, (eta6- arene)MII-carbonyl, and (eta6-arene)M IV-dihydride complexes bearing a disilaferracycle framework was accomplished. These M(II) and M(IV) complexes can easily generate coordinatively unsaturated 16e disilametallacycles, (eta6-arene)M II(Me2SiC6H4SiMe2), by dissociation of L or H2, and stoichiometric and/or catalytic double silylation of alkenes and alkynes was realized thorough this 16e intermediate.

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.

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.
