Coordination chemistry of the [Pt2(mu-S)2 (PPh3)4] metalloligand with pi-hydrocarbon derivatives of d6 ruthenium(II), osmium(II), rhodium(III) and iridium(III)

The reactivity of [Pt2(mu-S)2 (PPh3)4] towards [RuCl2 (eta6-arene)]2 (arene=C6 H6, C6Me6, p -MeC6 H4Pri = p-cymene), [OsCl2 (eta6- p -cymene)]2 and [MCl2 (eta5-C5Me5)]2 (M=Rh, Ir) have been probed using electrospray ionisation mass spectrometry. In all cases, dicationic products of the type [Pt2(mu-S)2(PPh3)4 ML]2+ (L=pi-hydrocarbon ligand) are observed, and a number of complexes have been prepared on the synthetic scale, isolated as their BPh4- or PF6- salts, and fully characterised. A single-crystal X-ray structure determination on the Ru p-cymene derivative confirms the presence of a pseudo-five-coordinate Ru centre. This resists addition of small donor ligands such as CO and pyridine. The reaction of [Pt2(mu-S)2 (PPh3)4] with RuClCp(PPh3) 2 (Cp=eta5-C5H5) gives [Pt2(mu-S)2(PPh3) 4RuCp]+. In addition, the reaction of [Pt2(mu-S)2(PPh3)4] with the related carbonyl complex [RuCl2(CO)3] 2, monitored by electrospray mass spectrometry, gives [Pt2(mu-S)2(PPh3)4 Ru(CO)3Cl]+.

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.

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).

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.

Genetic Incorporation of Olefin Cross-Metathesis Reaction Tags for Protein Modification

Olefin cross-metathesis (CM) is a viable reaction for the modification of alkene-containing proteins. Although allyl sulfide or selenide side-chain motifs in proteins can critically enhance the rate of CM reactions, no efficient method for their site-selective genetic incorporation into proteins has been reported to date. Here, through the systematic evaluation of olefin-bearing unnatural amino acids for their metabolic incorporation, we have discovered S-allylhomocysteine (Ahc) as a genetically encodable Met analogue that is not only processed by translational cellular machinery but also a privileged CM substrate residue in proteins. In this way, Ahc was used for efficient Met codon reassignment in a Met-auxotrophic strain of E. coli (B834 (DE3)) as well as metabolic labeling of protein in human cells and was reactive toward CM in several representative proteins. This expands the use of CM in the toolkit for “tag-and-modify” functionalization of proteins.

Catalytic activity and selectivity of a range of ruthenium complexes tested in the styrene/EDA reaction system

The complex ensemble of competing chemical processes (cyclopropanation, metathesis, dimerisation) involved in the reaction of ethyl diazoacetate with styrene is examined in the presence of a panel of ten ruthenium complexes. Our results, focusing on the catalysts’ activity and selectivity, showcased the new NHC-containing complex 10 and the Fischer carbene 7 as leading to best chemoselectivities for cyclopropanation while the bidentate Schiff-base complexes 3 and 4 provided highest stereoselectivity. The traditionally metathesis-active Grubbs I catalyst (5) could be manipulated, by working under high dilution, to display moderate activity in cyclopropanation whereas the Grubbs II catalyst (6) totally promoted metathesis. Data obtained with the above set of Ru complexes strongly support the premise that ligand structure and configuration in the Ru coordination sphere are essential factors in controlling the reaction pathways.

An eco-compatible strategy for the diversity-oriented synthesis of macrocycles exploiting carbohydrate-derived building blocks

An efficient, eco-compatible diversity-oriented synthesis (DOS) approach for the generation of library of sugar embedded macrocyclic compounds with various ring size containing 1,2,3-triazole has been developed. This concise strategy involves the iterative use of readily available sugar-derived alkyne/azide-alkene building blocks coupled through copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction followed by pairing of the linear cyclo-adduct using greener reaction conditions. The eco-compatibility, mild reaction conditions, greener solvents, easy purification and avoidance of hazards and toxic solvents are advantages of this protocol to access this important structural class. The diversity of the macrocycles synthesized (in total we have synthesized 13 macrocycles) using a set of standard reaction protocols demonstrate the potential of the new eco-compatible approach for the macrocyclic library generation.

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.
