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

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.

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: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

Synthesis of some ring-substituted ruthenocenes and their use in the preparation of Ru/ZSM-5 catalysts

A method is proposed for the preparation of Ru/ZSM-5 catalysts using substituted and non-substituted ruthenocenes.To this end, the following complexes have been synthesized and characterized: dimethyl-1,1′; diphenyl-1,1′; dibenzoyl-1,1′, and monobenzoyl ruthenocene.Results of ESCA intensity ratio and ir of adsorbed pyridine show differences in the surface segregation of Ru as well as in the cationic exchange of Ru with Broensted acid sites of the zeolite, when the catalysts is prepared using ring-substituted ruthenocene instead of ruthenocene itself.The binding energies of Ru 3d5/2 measured by ESCA are discussed.

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.

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).

Recent Advances in Cascade Reactions Initiated by Alcohol Oxidation

In this review, we attempt to answer the question: how can we construct complex functionalized molecules with significant added value from cheap and readily available alcohols in the simplest and most efficient manner? Accordingly, recent developments (mainly from the last five years) in the field of one-pot multiple transformations of alcohols are overviewed in terms of process simplification and optimization; sustainability; and atom, bond, step, and redox economy. Particular attention is paid to chemo- and stereoselective transformations with specific formation of particular bonds and configurations, leaving other parts of substrates unchanged.
