Fibrosis is the formation of abnormal scar tissue following repeated tissue injury, leading to the disruption of extracellular matrix homeostasis with loss of tissue architecture and function. In the developed world, fibrosis is a leading cause of morbidity and mortality whereby multiple organs can be individually affected. Over the last decade the alphav integrins have emerged as a target class with significant potential to intervene in multi-organ fibrosis due to their role in the activation of the key pro-fibrotic cytokine, transforming growth factor-beta. Although drug discovery efforts have been directed at members of this integrin sub-family in the past, the alphav integrins are currently undergoing a renaissance due to recent compelling target validation in fibrotic diseases. Historical drug discovery initiatives highlighted the challenges in both chemical tractability and design of robust pre-clinical and clinical studies in this area. The majority of approved drugs have targeted the alphaIIbbeta3 integrin for thrombosis, which demonstrates that only a small proportion of the integrin family have been shown to be tractable drug targets, probably as a result of their complex functional roles in both normal physiology and disease pathobiology. Recently, there has been large investment by the pharmaceutical industry into alphav-integrin drug discovery research that has facilitated the advancement of new small molecule therapeutics to clinical use. The aim of this chapter is to summarise the evidence for the alphav integrins in fibrotic disease, offer insight into alphav inhibitor small molecule drug design and provide an overview of the competitor and clinical landscapes to date.

We present a theoretical study of the electronic absorption spectrum of the 2-ferrocenyl-1,8-naphthyridine (FcNP) complex using the time-dependent density functional theory (TD-DFT) approach. The calculations were carried out at the DFT/LANL2DZ(Fe)/6-31++G(d) level of theory with nine DFT functionals of the type GGA (PBE, B97D), HGGA (B3LYP, PBE0), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP, LC-wPBE) in the condensed phase (CH2Cl2). The experimental spectrum for FcNP presents three electronic absorption bands (A, B, C) in the UV region and one band (D) in the visible region. We found that there is no unique functional that reproduces the entire electronic spectrum. GGA and LC-wPBE functionals predict large errors (up to 0.57 eV) for the UV bands. On the contrary, HGGA (PBE0), HMGGA (M05, M06) and range-separated (wB97XD, CAM-B3LYP) functionals give small errors for these bands, 0.18, 0.12 and 0.25 eV, respectively. Band D is well described by all the functionals with errors up to 0.26 eV, except by the M05 and M06 functionals, which fail in this region with significant errors (0.52 and 0.56 eV). The analysis of the excitation energies shows that the PBE0, wB97XD and CAM-B3LYP functionals predict the best agreement with the experimental data. The two stronger bands (A, B) in the UV region are assigned to a ligand?ligand charge transfer (L-LCT) that involves the cyclopentadienyl rings (Cp) and the naphthyridine fragment (NP), and then associated with pi ? pi? electronic transitions. The two weaker bands (C, D) are assigned to a charge transfer from ligand (Cp) to metal (Fe)-ligand (NP) (L-MLCT) which is mainly addressed through the dxy and dz2 atomic orbitals, respectively. No charge transfer is observed between metal and NP ligand. It was shown that the theoretical methods used for understanding the electronic absorption properties of FcNP were adequate because the results showed an excellent agreement with experimental ones.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1931-44-8, 7-Amino-1,8-naphthyridin-2(8H)-one, introducing its new discovery.

Several novel fluorogenic N-aminoacylnaphthyridine substrates were synthesized in good yield and tested for their ability to detect pathogenic bacteria in agar-based cell culture. Simple 2-N-(beta-alanyl)amino-5,7- dialkylnaphthyridine substrates were selectively hydrolysed by beta-alanylaminopeptidase expressing bacteria, but were subject to diffusion in the agar medium. Diffusion was reduced in the 2-N-(beta-alanyl)amino-7- alkylnaphthyridine substrates with longer alkyl chains, but inhibition of growth was increased. 2-N-(beta-Alanyl)amino-7-octylnaphthyridine inhibited the growth of all species tested, except for strains resistant to colistin/polymyxin, providing a rationale for the development of substrates for the selective detection of drug resistant species in clinical samples.

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.

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.

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

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.

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.

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.
