Novel (non-fluoroquinolone) inhibitors of bacterial type II topoisomerases (NBTIs) are an emerging class of antibacterial agents. We report an optimized series of cyclobutylaryl-substituted NBTIs. Compound 14 demonstrated excellent activity both in vitro (S. aureus MIC90 = 0.125 mu g/ mL) and in vivo (systemic and tissue infections). Enhanced inhibition of Topoisomerase IV correlated with improved activity in S. aureus strains with mutations conferring resistance to NBTIs. Compound 14 also displayed an improved hERG IC50 of 85.9 mu M and a favorable profile in the anesthetized guinea pig model. (C) 2017 Elsevier Ltd. All rights reserved.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 82-76-8, Name is 8-(Phenylamino)naphthalene-1-sulfonic acid, SMILES is O=S(C1=C2C(NC3=CC=CC=C3)=CC=CC2=CC=C1)(O)=O, belongs to naphthyridine compound. In a document, author is Siddiqui, Mohammad N., introduce the new discover, Formula: https://www.ambeed.com/products/82-76-8.html.

The synthesis of Poly[1,5-naphthyridine-(3-hexylthiophene)] (1) semi-conducting polymer has been accomplished by adopting both conventional and microwave-assisted Suzuki-Miyaura cross-coupling reaction between 3-hexylthiophene-2,5-diboronic ester and 2,6-dibromo-1,5-naphthyridine. The synthesized copolymer was characterized by modern spectroscopic techniques including percent reflectance (%R), gel permeation chromatography (GPC), cyclic voltammetry (CV), Raman spectroscopy, thermogravimetric analysis (TGA), FTIR and NMR. The morphology of copolymer was examined via FESEM. Optical bandgap was calculated from the absorption edge of %R and found 2.26 eV. The electrochemical and transport properties of 1 were investigated both in the bulk as well as in thin film form. Cyclic voltammetry (CV) results of 1 as a bulk form in H2SO4 solution indicated that the concentration of the polymer in the solution is not well defined because of polymer poor solubility in aqueous solutions. On the other hand, the sulfur group which works as electron donating makes the system more electron-rich. This can be explained by the absence of the reduction peak. For the thin film, two single oxidation peaks were obtained at around 0 V and 0.3 V for both cases. Different solvents can tune the transport properties of the polymer as can be seen from the two CVs where BF3 exhibited enhanced transport properties over ACN. This polymer was also employed in dye-sensitized solar cells as a photosensitizer. The solar cell under AM 1.5 G illumination at 100 mW/cm(2) shows power conversion efficiency of 0.67% with an open circuit voltage of 621 mV, a short circuit current of 2.0 mA/cm(2), and a fill factor of 55%.

C., once mentioned the application of 96-49-1, Name is Ethylene carbonate, molecular formula is C3H4O3. Now introduce a scientific discovery about this category, Safety of Ethylene carbonate.

A series of dinuclear and tetranuclear first-row transition metal complexes were synthesized with the dinucleating ligand 2,7-bis(di(2-pyridyl) fluoromethyl)-1,8-naphthyridine (DPFN). The coordination pocket and rigidity of the DPFN ligand enforces pseudo-octahedral geometries about the metal centers that contain chloro, hydroxo, and aqua bridging ligands forming a diamond shaped configuration with metal-metal distances varying from 2.7826(5) to 3.2410(11) angstrom. Each metal center in the dinuclear complexes has an additional open coordination site that accommodates terminal ligands in a syn geometry of particular interest in catalyst design. The complexes are characterized by electronic spectroscopy, electrochemistry and potentiometric titration methods.

Room-temperature activation of the aromatic C-H bond by the [Ru-2(CO)(4)](2+) core has been achieved. The reactions of 2-phenyl-1,8-naphthyridine (phNP) and 2-(2,5-dimethyl-3-furyl)-1,8-naphthyridine (Me-2-fuNP) with [Ru-2(CO)(4)(MeCN)(6)][BF4](2) in dichloromethane provide the agostic-cyclometalated compounds [Ru-2(phNP)(C6H4-NP)(CO)(4)][BF4] (1) and [Ru-2(Me(2)fuNP)(C4OMe2-NP)(CO)(4)][BF4] (2), respectively. In both compounds, one of the ligands is ortho-metalated, while the second ligand is engaged in an agostic interaction. The ortho metalation is preferred over the potential S coordination for 2-(2-thienyl)1,8-naphthyridine (thNP), yielding [Ru-2(thNP)(C4H2S-NP)(CO)(4)][BF4] ( 3). In acetonitrile, the compound [Ru-2(thNP)(2)(CO)(4)][BF4](2) (4) is obtained exclusively. The donation of a C-H bonding electron pair to the Ru-Ru sigma* LUMO and back-donation from the filled Ru-Ru pi* orbital to the C-H sigma* orbital cause facile C-H bond cleavage. In contrast, the isoelectronic [Rh-2](4+) provides the agostic compounds [Rh-2(OAc)(3)(phNP)Cl] (5) and [Rh-2(L)(eta(1)-L)(OAc)(2)(CH3CN)(2)][BF4](2) (L = phNP, np1NP (2-(2- naphthyl)-1,8-naphthyridine) for compounds 6 and 7, respectively).

In a document, author is Hu, Wenkang, introduce the new discover.

A novel unsymmetrical triazolyl-naphthyridinyl-pyridine ligand was designed and synthesized, and employed in the synthesis of a heterogeneous copper complex on reduced graphene oxide. The resulting copper composite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX). This supported copper catalyst containing unsymmetrical triazolyl-naphthyridinyl-pyridine (only 0.1 mol%) showed excellent catalytic activity in water with good recyclability. Various functionalized quinoline derivatives were successfully synthesized in high yields through the green strategy in water. Other heterocyclic compounds, such as pyridine, 2-(pyridin-2-yl)quinoline, 1,8-naphthyridine, 5,6-dihydronaphtho[1,2-b][1,8]naphthyridine and 2-(pyridin-2-yl)-1,8-naphthyridine derivatives, were achieved in water with more than 80% yields. Mechanism studies revealed that this transformation occurs via dehydrogenation, condensation, and transfer hydrogenation and dehydrogenation processes which was supported by a deuterium labeling experiment.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 136-95-8, in my other articles. Category: naphthyridines.
