QSAR studies on substituted 3- or 4-phenyl-1,8-naphthyridine derivatives as antimicrobial agents

Quantitative Structure Activity Relationship correlating the antitubercular and antibacterial (Staphylococcus aureus and Escherichia coli) activities with the structural descriptors of reported naphthyridine derivatives was developed. The data were divided into training and test sets. The former was used to develop the regression model and the latter was used to examine the predictive capability of these models. The statistical measures such as squared correlation coefficient (r (2) = 0.79-0.84), adjusted squared correlation coefficient (r (2) (adj) = 0.78-0.83) F-ratio (26.85-67.16), and cross-validation (q (2) = 0.74-0.79) were found to be satisfactory for all activities and the predictions were within the 99% confidence level. The models contained atom type, thermodynamic, structural, and electrotopological descriptors which emphasized the importance of the size, shape, and the lipophilicity of the molecule.

Selective Synthesis of a Series of Isostructural (MCuI)-Cu-II Heterobimetallic Complexes Spontaneously Assembled by an Unsymmetrical Naphthyridine-Based Ligand

Metal-metal cooperation is integral to the function of many enzymes and materials, and model complexes hold enormous potential for providing insights into the capabilities of analogous multimetallic cores. However, the selective synthesis of heterobimetallic complexes still presents a significant challenge, especially for systems that hold the metals in close proximity and feature open or reactive coordination sites for both metals. To address this issue, a rigid, naphthyridine-based dinucleating ligand featuring distinct binding environments was synthesized. This ligand enables the selective synthesis of a series of (MCuI)-Cu-II bimetallic complexes (M=Mn, Fe, Co, Ni, Cu, Zn), in which each metal center exclusively occupies its preferred binding pocket, from simple chloride salts. The precision of this selectivity is evident from cyclic voltammetry, ESI-MS and anomalous X-ray diffraction measurements.

A Short Synthesis of the Plant Alkaloid 4-Methyl-2,6-naphthyridine

A new synthesis of the 2,6-naphthyridine alkaloid 4-methyl-2,6-naphthyridine from Antirrhinum majus has been developed. Key steps are a regioselective oxidation of 3-bromo-4,5-dimethylpyridine to the corresponding 4-formyl derivative, and the annulation of the second pyridine ring by Suzuki-Miyaura cross-coupling using (E)-2-ethoxyvinylboronic acid pinacol ester as a masked acetaldehyde equivalent. This protocol gives the alkaloid in four steps starting from commercially available 3,4-dimethylpyridine in 15% overall yield. This annulation protocol should be useful for the synthesis of other condensed pyridines as well.

Naphthyridine-based symmetrical and unsymmetrical pyridinium amides in sensing of biotin salt

Two naphthyridine-based receptors have been designed and synthesised for biotin salt. The compounds serve as good hosts for the detection of biotin carboxylate rather than biotin ester. The correct dispositions of the binding groups under an isophthaloyl spacer enable the receptors to bind both the cyclic urea and the carboxylate ends simultaneously with moderate binding constant values. The receptors are effective for the binding of tetrabutylammonium salt of biotin with a concomitant increase in the fluorescence of naphthyridine and show appreciable binding of biotin salt in CH3CN containing 1.2% DMSO. The binding was monitored in CH3CN containing 1.2% DMSO and DMSO using H-1 NMR, UV-vis and fluorescence spectroscopic methods.

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 6165-69-1 help many people in the next few years. COA of Formula: C4H5BO2S.

A novel Schiff-base fluorescent probe based on 1,8-naphthyridine and naphthalimide for Al3+

A novel Schiff-base, 7-acetamino-4-methyl-1,8-naphthyridine-2-carbaldehyde-(1′,8′-naphthalenedicarbonyl) hydrazone (HL) was designed, synthesized and evaluated as a fluorescent probe. The fluorescence properties of this probe towards various metal ions were investigated by UV-vis and fluorescence spectra in methanol. Test results indicated that the probe had high selectivity towards Al3+ over other commonly coexisting metal ions. Upon addition of Al3+, the fluorescence intensity at 414 nm increased significantly due to the inhibition of the PET process. The binding constant (Ma) of Al3+ binding to HL was calculated to be 5.64 x 10(4) M-1 from a Benesi-Hildebrand plot, and the detection limit(LOD) of HL for sensing Al3+ was calculated to be 0.13 mu M. The binding stoichiometry between HL and Al3+ was determined as 1:1 by the Job’s plot. Furthermore, the probe was chemically reversible for Al3+ in methanol by the addition of Na(2)EDTA solution.

Bispyranopyrazoles as Green Corrosion Inhibitors for Mild Steel in Hydrochloric Acid: Experimental and Theoretical Approach

In the present study, we have synthesized two novel corrosion inhibitors BP-1 and BP-2 and evaluated their corrosion inhibition property on mild steel (MS) in acid solution through weight loss and electrochemical corrosion techniques. The corrosion test results reveal that both compounds inhibit corrosion by an adsorption mechanism and display inhibition efficiency more than 95% at a low concentration of 1.72 x 10(-4) M. From the surface analysis of the protective film on MS, it was corroborated that adsorption of inhibitor molecules occurred on the MS surface through chemisorption, which further suppresses the corrosion rate. Density functional theory simulated data helps correlate the experimental trend with the theoretical study.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13922-41-3, in my other articles.

In each of them, the coordinate geometry of Cu atom is a distorted square planar configuration with bond distances and angles in the normal range. Moreover, compound 2 features one-dimensional zigzag chains which are cross-linked by the metal complex cations and PF6- anions through hydrogen bonding interactions. The HOMO-LUMO energy gaps of 1-2 estimated by the cyclic voltammetry (CV) show values in the order of 1 > 2. Both 1 and 2 show low-energy bands ranging from 360 to 430 nm and available florescence in the solid state at room temperature with lambda(max) = 532-541 nm. The UV-vis absorption spectra of 1-2 show obvious red-shifts compared with those of the corresponding quinoline containing Cu(I) complexes [Cu(QN)(2)]PF6 (QN = 8-diphenylphosphino quinoline), exhibiting the HOMO-LUMO energy gaps of 1-2 should be narrower than that of [Cu(QN)(2)]PF6.

Palladium complexes with an annellated mesoionic carbene (MIC) ligand: catalytic sequential Sonogashira coupling/cyclization reaction for one-pot synthesis of benzofuran, indole, isocoumarin and isoquinolone derivatives

Two Pd(II) complexes (1 and 2) featuring a fused pi-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand have been synthesized and structurally characterized. Both complexes effectively catalyze the one-pot synthesis of benzofuran starting from phenylacetylene and 2-iodophenol under mild conditions. Complex 1 is found to be an excellent catalyst for the straightforward access to a library of benzofuran, indole, isocoumarin and isoquinolone derivatives by the reaction of terminal alkynes with 2-iodo derivates of phenol, N-methyl aniline, benzoic acid and N-methyl benzamide, respectively. The general utility of the catalytic method is demonstrated using a variety of diversely substituted terminal alkynes and the corresponding desired products are obtained in good to excellent yields. On the basis of control experiments, a two-cycle mechanism is proposed which involves the Sonogashira coupling of 2-iodo derivatives with alkynes and the subsequent cyclization of the corresponding 2-alkynyl compounds.
