Mixed-Ligand Complexes of Ruthenium(II): Factors Governing Binding to DNA

Binding and spectroscopic parameters for a series of mixed-ligand complexes on binding to DNA have been determined.The application of mixed-ligand complexes permits the variation in geometry, size, hydrophobicity, and hydrogen-bonding ability by systematic variation of complex ligands and the determination of how these factors contribute to DNA binding affinity.Ligands employed include 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen), 4,7-diphenylphenanthroline (DIP), 5-nitrophenanthroline (5-NO2-phen), 4,5-diazafluorene-9-one (flone), and 9,10-phenanthrenequinonediimine (phi).Measurements include equilibrium binding isotherms and enantioselectivities associated with binding, the degree of absorption hypochromism and red shift in the ruthenium charge-transfer band, increases in emission intensities and excited-state lifetimes, perturbations in excited-state resonance Raman spectra (which reflect changes in excited-state charge-transfer distributions as a result of binding to DNA), and determinations of helical unwinding.The complexes examined, with the exception of Ru(bpy)32+, all appear to intercalate and surface-bind to DNA, and for those that bind appreciably, enantioselectivity is observed.Based upon the measurements of spectroscopic properties and binding isotherms, the intercalating ability appears to increase over the series bpy<Quality Control of: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II).

Synthesis and evaluation of a carbosilane congener of ferroquine and its corresponding half-sandwich ruthenium and rhodium complexes for antiplasmodial and beta-hematin inhibition activity

A silicon-containing congener of ferroquine (1) was synthesized by incorporating an organosilicon motif in the lateral side chain of ferroquine. Compound 1 was then further reacted with dinuclear half-sandwich transition-metal precursors [Ru(Ar)(mu-Cl)Cl]2 (Ar = eta6-p-iPrC6H4Me, eta6-C6H6, eta6-C6H5OCH2CH2OH), [Rh(COD)(mu-Cl)]2, and [RhCp(mu-Cl)Cl]2, to yield a series of heterometallic organometallic complexes (2-6). Compound 1 coordinates selectively in a monodentate manner to the transition metals via the quinoline nitrogen of the aminoquinoline scaffold. All of the compounds were characterized using various analytical and spectroscopic techniques, and the molecular structure of compound 1 was elucidated by single-crystal X-ray diffraction analysis. Furthermore, the in vitro antiplasmodial activity of compounds 1-6 was established against the chloroquine-sensitive (NF54) and chloroquine-resistant (Dd2) strains of the malaria parasite Plasmodium falciparum.

Lipophilicity-antiproliferative activity relationship study leads to the preparation of a ruthenium(II) arene complex with considerable in vitro cytotoxicity against cancer cells and a lower in vivo toxicity in zebrafish embryos than clinically approved cis-platin

Ru(II)-arene complexes are attracting increasing attention due to their considerable antitumoral activity. However, it is difficult to clearly establish a direct relationship between their structure and antiproliferative activity, as substantial structural changes might not only affect their anticancer activity but also tightly control their activation site(s) and/or their biological target(s). Herein, we describe the synthesis and characterization of four ruthenium(II) arene complexes bearing bidentate N,O-donor Schiff-base ligands ([Ru(eta6-benzene)(N-O)Cl]) that display a significantly distinct antiproliferative activity against cancer cells, despite their close structural similarity. Furthermore, we suggest there is a link between their respective antiproliferative activity and their lipophilicity, as the latter affects their ability to accumulate into cancer cells. This lipophilicity-cytotoxicity relationship was exploited to design another structurally related ruthenium complex with a much higher antiproliferative activity (IC50 > 25.0 muM) against three different human cancer cell lines. Whereas this complex shows a slightly lower activity than that of clinically approved cis-platin against the same human cancer cell lines, it displays a lower toxicity in zebrafish (Danio rerio) embryos at concentrations up to 20 muM.

Organometallic pyridylnaphthalimide complexes as protein kinase inhibitors

A new metal-containing scaffold for the design of protein kinase inhibitors is introduced. The key feature is a 3-(2-pyridyl)-1,8-naphthalimide “pharmacophore chelate ligand”, which is designed to form two hydrogen bonds with the hinge region of the ATP-binding site and is at the same time capable of serving as a stable bidentate ligand through C-H activation at the 4-position of the electron-deficient naphthalene moiety. This C-H activation leads to a reduced demand for coordinating heteroatoms and thus sets the basis for a very efficient three-step synthesis starting from 1,8-naphthalic anhydride. The versatility of this ligand is demonstrated with the discovery of a ruthenium complex that functions as a nanomolar inhibitor for myosin light-chain kinase (MYLK or MLCK).

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., Electric Literature of 37366-09-9

Energy transfer dynamics in multichromophoric arrays engineered from phosphorescent PtII/RuII/OsII centers linked to a central truxene platform

A rigid star-shaped tetrachromophoric trimetallic complex engineered from a 5,5?,10,10?,15,15?-hexabutyltruxene platform functionalized in the 2,7,12 positions with three different metal centers, namely, a terpyridine-Pt(II) ethynylene unit and Ru(II) and Os (II) bipyridine centers, was synthesized in a controlled fashion and characterized by 1H NMR and mass spectrometry. The protocol was devised in such a way that key mono and dinuclear model complexes and two reference truxene ligands could also be prepared. Room temperature (RT) optical absorption and RT and 77 K luminescence studies were performed on the truxene ligands, the trimetallic species, the various mono- and binuclear complexes and precursors lacking the truxene fragment; RT nanosecond transient absorption measurements were also carried out in particular cases. The electronic properties of the Ru and Os subunits in the arrays were found to be unaffected by the presence of the truxene core whereas direct linking of the Pt subunit to the truxene via the ?-alkyne bond markedly influences the spectroscopic behavior of the Pt center. Remarkably the truxene phosphorescence was clearly established in the two ligands (lifetime of 4.3 s for the mono ethynyl-bipy substituted truxene and 17.5 ms for the bis ethynyl-bipy substituted truxene) and also detected in the Pt-containing complexes PtL? (model Pt-truxene) and Pt-Os (Pt-truxene-Os dyad) at low temperature. This is attributed to the closeness in energy of the Pt 3CT level and the truxene triplet at low temperature and to the spin-orbit coupling induced by the Pt heavy atom. Transient absorbance measurements evidenced the population of the Pt-based triplet in the Pt-truxene mononuclear complex PtL? at room-temperature. For the trimetallic complex, where the various centers exhibit an energy gradient for the local excited levels, and following an approach based on the use of selected excitation of the components, an initial energy transfer was found to occur from the central truxene unit toward the peripheral Pt, Ru, and Os metal-based centers. Subsequent Pt-based and Ru-based excited state depletion contributes to the final sensitization of the low-lying Os triplet excited state; the excited state dynamics for these multicascade processes are examined in detail.

Catalysts for the asymmetric transfer hydrogenation of various ketones from [3-[(2S)-2-[(diphenylphosphanyl)oxy]-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride] and [Ru(eta6-arene)(mu-Cl)Cl]2, Ir(eta5-C5Me5)(mu-Cl)Cl]2 or [Rh(mu-Cl)(cod)]2

The combination of [3-[(2S)-2-[(diphenylphosphanyl)oxy]-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride] with [Ru(eta6-arene)(mu-Cl)Cl]2, Ir(eta5-C5Me5)(mu-Cl)Cl]2 or [Rh(mu-Cl)(cod)]2, in the presence of KOH/isoPrOH, has been found to generate catalysts that are capable of enantioselectively reducing alkyl, aryl ketones to the corresponding (R)-alcohols. Under optimized conditions, when the catalysts were applied to the asymmetric transfer hydrogenation, we obtained the secondary alcohol products in high conversions and enantioselectivities using only 0.5 mol% catalyst loading. In addition, [3-[(2S)-2-{[(chloro(?4-1,5-cyclooctadiene)rhodium)diphenyl phosphanyl] oxy}-3-phenoxypropyl]-1-methyl-1H-imidazol-3-ium chloride], (6) complex is much more active than the other analogous complexes in the transfer hydrogenation. Catalyst 6 acts as excellent catalysts, giving the corresponding (R)-1-phenyl ethanol in 99% conversion in 30 min (TOF ? 396 h?1) and in high enantioselectivity (92% ee).
