A series of nalidixic acid-based hydrazones and their Au III, PtIV metal complexes have been synthesized and evaluated for their in vitro antimicrobial activity based on dimension of the diameter of inhibition zone formed round the well against a panel of reference strains of microorganisms, including Gram-positive bacteria, Gram-negative bacteria, and fungi Candida albicans and Candida tropicalis. Nalidixic acid hydrazone derivatives were obtained by condensation reaction of nalidixic acid hydrazide with substituted aromatic aldehydes and acetophenone. The complexes of Au III, Pt IV metals with nalidixic acid hydrazone derivatives were synthesized. All compounds have been characterized by elemental analysis, FT-IR,1H NMR and13C NMR spectra. The antimicrobial activity indicated that all ligands and metal complexes showed significant activity of anti-bacterial, antifungal activity comparable to that of parent and standard.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C8H5ClN2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 15936-10-4, Name is 2-Chloro-1,8-naphthyridine, molecular formula is C8H5ClN2

A series of novel cyclic and V-shaped cuprous clusters, (HNEt 3)2 [Cu6(bmsapy)4] (1), [Cu 8(banlny)4] (2) and [Cu6(ansny)4Cl] (CF3SO3) (3), were synthesized. Compounds (1) and (2) possess a similar cyclic metal structural arrangement, and the metallic arrangement of compound (2) is as in (1) with an insertion of a pair of ligand-unbridged Cu(I) atoms. Compounds (1) and (2) both have unusual ligand-unbridged Cu(I)-Cu(I) separations, but compound (3) does not. The ligand-unbridged Cu(I)-Cu(I) distances in (2) are shorter than those in (1). In absorption spectra, compound (2) displayed red shifts from (1) due to the increase in nuclearity and the number of the aromatic rings in ligands. TDDFT calculations suggest that in HOMOs, the major molecular orbital contribution is from the six Cu(I) atoms implying that the photoluminescent property of (1) is dependent on the cyclic hexacopper arrangement rather than that of (HNEt 3) [Cu3(btsapy)2] (4).

The ruthenium complexes bearing 1,8-naphthyridine (napy) and terpyridine analogous (N,C,N)-tridentate ligands were synthesized and characterized. The reaction of [RuCl2(napy-kappa2,N,N?)(dmso) 2] with 2 equiv of AgPF6 and subsequent addition of LH and CO gave [RuL(napy-kappa2N,N?)(CO)](PF6) n (6a: L = N-methyl-3,5-di(2-pyridyl)-4-pyridyl, n = 2; 6b: L = 2,6-di(2-pyridyl)phenyl, n = 1) via [RuL(napy-kappa2N,N? )(dmso) (PF6)n (5a: L = N-methyl-3,5-di(2-pyridyl)-4-pyridyl, n = 2; 5b: L = 2,6-di(2-pyridyl)phenyl, n = 1). The crystal structures of 5a and 6a show distorted octahedral coordination with the tridentate (N,C,N)-ligand as mer-fashion, two nitrogens of bidentate napy and the sulfur of DMSO (5a) or the carbon of the CO ligand (6a). Detailed experiments for irradiation and variable-temperature 1H NMR studies reveal a fluxional process of the chelated napy ligand in solution.

A one-pot method for the preparation of 1,8-naphthyridine derivatives is reported. The method involves the dimetalation of an appropriate N-2-pyridylpivalamide or tert-butylcarbamate followed by reaction with a beta-dimethylamino or beta-alkoxyacrolein derivative. This method is also applicable to 1,6-naphthyridines. Georg Thieme Verlag Stuttgart.

A dicarbonylruthenium(II) complex containing bidentate 2-(2-pyridyl)-1,8-naphthyridine, as well as monodentate aqua and chlorido ligands, were isolated and characterized using spectroscopic techniques and single crystal X-ray diffraction. These data indicate that geometrical isomerization occurs during the substitution reaction involving a superacid. Density functional theory (DFT) calculations were performed on the plausible geometrical isomers. The DFT-optimized structures and calculated infrared spectra suggest that the experimentally obtained structure is stable.

We describe the synthesis and antibacterial activity of a series of tetracyclic naphthyridones. The members of this series act primarily via inhibition of bacterial translation and belong to the class of novel ribosome inhibitors (NRIs). In this paper we explore the structure-activity relationships (SAR) of these compounds to measure their ability both to inhibit bacterial translation and also to inhibit the growth of bacterial cells in culture. The most active of these compounds inhibit Streptococcus pneumoniae translation at concentrations of <5 muM and have minimum inhibitory concentrations (MICs) of <8 mug/mL against clinically relevant strains of bacteria. 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: Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate, you can also check out more blogs about96568-07-9
