New ruthenium complexes with 1,8-naphthyridine (napy) or derivatives thereof as ligands have been prepared and characterized. Three groups of complexes were obtained. The first consists of three dinuclear ruthenium complexes with two ligands (1,8-naphthyridine and pyridopyrazine) co-ordinated to two ruthenium ions in a bridging fashion. The second consists of two ruthenium dinuclear complexes having one ligand (2,7-dimethoxy-or 2,7-dichloro-1,8-naphthyridine, abbreviated to dmnapy and dcnapy respectively) co-ordinated to two ruthenium atoms. Proton NMR spectra for both complexes in aqueous solution and in acetonitrile revealed the conversion of a symmetrical form, suggesting dinucleating behaviour of the ligand, into an asymmetrical form, suggesting mononucleating behaviour of the ligand. The third group consists of a mono- and a di-nuclear complex with the ligand 2,7-di(phenylazo)-1,8-naphthyridine. The catalytic activity of the novel naphthyridine complexes in oxidation reactions has been studied. The catalytic oxidation of alcohols and the epoxidation of trans-stilbene were examined and the different reaction rates and selectivities are discussed in a comparative way. The active high-valent species resulting from the [Ru2(napy)2(H2O)4Cl(OH)] 4+ complex is discussed in more detail.

A conjugated donor-acceptor-donor molecule incorporating a central moiety of naphthyridine and two terminal moieties of di(hydroxyethyl)aniline connected by ethynyl bridges shows two-stage color changes on binding with mercury(II) ion in Me2SO/H2O (1:1) solution with a bathochromic shift from 450 to 498 nm, and then an extraordinarily large hypsochromic shift to 378 nm. In comparison, the corresponding donor-acceptor molecule weakly binds mercury(II) ion with a hypsochromic shift from 408 to 375 nm. Our designed sensor of the donor-acceptor-donor system shows high selectivity toward mercury(II) ion over other competing metal ions.

Reference of 254-60-4, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 254-60-4, Name is 1,8-Diazanaphthalene, molecular formula is C8H6N2. In a Article£¬once mentioned of 254-60-4

The complexes [Ru(bipy)2(napy-N)(MeCN)][PF6]2 1 and [Ru(bipy)2(napy-N,NA?);][PF6]2 2(bipy = 2,2?-bipyridine, napy = 1,8-naphthyridine) were prepared, and their crystal structures determined by X-ray analysis. The crystal structure of 1 displays an octahedral co-ordination with monodentate napy, acetonitrile and two chelating bipy. Despite the inequivalency of two nitrogens of napy in 1 in the solid state, the 1H NMR spectra in the aromatic region resemble those of 2 over the range -90 to 60C, which implies dynamic behaviour of napy in 1 in solution. Both 1 and 2 were reduced irreversibly at -0.98 V (vs. Ag-AgCl) in dimethylformamide at -20C, and the process gradually becomes a reversible redox reaction on increasing the temperature to 30C. An EPR study revealed that one-electron reduction of 1 takes place in the napy-localized orbital without appreciable increase in electron density on one of the nitrogens of napy. The distinct inequivalence in the charge density between the two nitrogen atoms of singly reduced napy results in stabilization of the N rather than N,N? co-ordination mode.

Chemistry is traditionally divided into organic and inorganic chemistry. category: naphthyridine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 254-60-4

The controlled potential electrolysis of [Ru(bpy)(napy)2(CO)2](BF4)2 (1; bpy = 2,2′-bipyridine, napy = 1,8-naphthyridine) in the presence of LiBF4 in CO2-saturated DMSO at -1.65 V (vs. Ag/Ag+) produced CO and Li2CO3 [Eq. (a)], while similar electrolysis in the presence of (CH3)4NBF4 resulted in formation of acetone together with (CH3)3N and {(CH3)4N}2CO3 [Eq. (b)]. This represents the first almost selective generation of acetone upon electrochemical reduction of CO2. The selectivity is ascribed to depression of reductive cleavage of the Ru-CO bond of 1 due to an attack of the nonbonded nitrogen atom of napy at the carbonyl carbon atom.

A series of naphthyridine and naphthyridinone allosteric dual inhibitors of Akt1 and 2 have been developed. These compounds have been optimized to have potent dual activity against the activated kinase as well as the activation of Akt in cells. One molecule in particular, compound 17, has potent inhibitory activity against Akt1 and 2 in vivo in a mouse lung and efficacy in a tumor xenograft model.

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: 1,8-Diazanaphthalene, you can also check out more blogs about254-60-4

254-60-4, Name is 1,8-Diazanaphthalene, belongs to naphthyridine compound, is a common compound. Computed Properties of C8H6N2In an article, once mentioned the new application about 254-60-4.

Reactions of the dinuclear palladium(I) complex [Pd2Cl2(RNC)4] (R = 2,4,6-Me3C6H2) 1 with the N-donor compounds 2,2?-bipyridyl (bipy), 1,10-phenanthroline (phen), and 2,9-dimethyl-1,10-phenanthroline (dmphen) gave dipalladium(I) complexes with chelating N-donor ligands, [Pd2(RNC)2L2] [PF6]2 (L = bipy 2, phen 3 or dmphen 4). The structures of 2 and 4 were characterized by X-ray crystallography. The cation of 2 is composed of two Pd atoms joined by a sigma bond [2.518(3) A] each of which has a square-planar co-ordination involving a terminal isocyanide and a chelating bipy ligand. Complex 3 is expected to have a structure similar to 2 on the basis of spectroscopic data. Complex 4 exhibits a distorted dinuclear structure due to the steric bulk of the N-donor ligand. The Pd-Pd bond length is 2.599(2) A. Each dmphen ligand chelates to a Pd atom and the isocyanide acts as a semibridging ligand. The similar reactions of complex 1 with 2,2?-biquinoline (bquin) and 1,8-naphthyridine (napy) afforded the isocyanide-bridged dipalladium(I) complexes, [Pd2(mu-RNC)2(bquin)2]-[PF6] 2 5 and [Pd2(mu-RNC)2(napy)4][PF6] 2 6, in 24-36% yields. Complex 6 comprises a dinuclear palladium(I) core bridged by two isocyanide ligands [Pd-Pd 2.747(4) A] with four terminal napy ligands co-ordinated in a monodentate fashion.

Crystallography has guided the hybridization of two series of Trypanosoma brucei N-myristoyltransferase (NMT) inhibitors, leading to a novel highly selective series. The effect of combining the selectivity enhancing elements from two pharmacophores is shown to be additive and has led to compounds that have greater than 1000-fold selectivity for TbNMT vs HsNMT. Further optimization of the hybrid series has identified compounds with significant trypanocidal activity capable of crossing the blood-brain barrier. By using CF-1 mdr1a deficient mice, we were able to demonstrate full cures in vivo in a mouse model of stage 2 African sleeping sickness. This and previous work provides very strong validation for NMT as a drug target for human African trypanosomiasis in both the peripheral and central nervous system stages of disease.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 17965-71-8, help many people in the next few years.Safety of 3-Bromo-1,5-naphthyridine

A number of 4-aminopyrazolo[3,4-b]pyridines 5-carboxylic acid esters (2-8) were synthesized and evaluated for their binding affinity at the A1, A2A, and A3 adenosine receptors (AR), in bovine cortical membranes, as well as for their affinity toward human A1AR (hA 1AR). Some of the new compounds were characterized by a high affinity and selectivity toward the A1 receptor subtype, showing a significant improvement in comparison with other pyrazolo-pyridines previously reported in the literature. In particular the methyl ester 2h as well as the isopropyl ester 5h, both of them bearing a p-methoxyphenylethylamino side chain at the position 4, presented K1 values of 6 and 7 nM, respectively. To rationalize the relationships between structure and affinity of the novel compounds, a 3D QSAR model was also generated starting from compounds belonging to different classes of known A1AR antagonists. 2005 American Chemical Society.
