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.

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.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

Luminescent materials simultaneously exhibiting superior luminescence efficiency, thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) properties in the solid state are eagerly required for highly efficient non-doped organic light-emitting diodes (OLEDs). Herein, two new emitters, namely ND-AC and CND-AC, featuring a naphthyridine or cyano-naphthyridine segment as the electron acceptor and an acridine unit as the electron donor were designed, synthesized and investigated. The nearly orthogonal molecular configuration of the target emitters not only endows them with small energy differences between singlet and triplet states for ensuring TADF character but also affords a remarkable AIE feature. Due to the high photoluminescence quantum yields, and excellent TADF and AIE characteristics, the doped and non-doped OLEDs based on ND-AC exhibit outstanding performances with maximum external quantum efficiencies of 16.8% and 12.0%, respectively. These results demonstrate that the naphthyridine-based emitters have a promising application in OLEDs.

New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Lewis, Madeline M., once mentioned the application of 99-55-8, Name is 2-Methyl-5-nitroaniline, molecular formula is C7H8N2O2.

The development of novel pi-conjugated charge transfer mediators is at the forefront of current research efforts and interests. Among the plethora of building blocks, diketopyrrolopyrroles have been widely employed, associated to the ease of tailoring their optoelectronic properties by systematic peripheral substitutions. It is somehow of surprise to us that their six-member ring bis-lactam analogues, naphthyridines have been overlooked and reports are scarce and almost solely limited to their use in polymeric materials. Herein we report a comprehensive theoretical analysis of the charge transfer properties of 1,5-naphthyridine-based materials by means of a number of bespoke model systems, further able to quantitatively predict experimental mobility observations. Our results imply that thiophene substituted naphthyridine crystalline materials represent a promising class of organic pi-conjugated systems with an experimentally observed ability to self-assemble in the solid state conforming to one dimensional stacking motifs. These highly sought-after charge propagation channels are characterised by large wavefunction overlap and thermal integrity and have as a result the potential to outperform currently exploited alternatives. We anticipate this work to be of interest to materials scientists and hope it will pave the way towards the realisation of novel charge transfer mediators exploiting naphthyridine chemistries.

Background: Naphthyridine scaffold is an important pharmacophore in compounds which have shown various biological activities like antiviral, antimicrobial, anticancer, antiinflammatory and analgesic. This scaffold is also reported to exhibit activity against HIV, HCMV, HSV, HPV and HCV. Antiviral activity displayed by many naphthyridine analogs is in nM range. Only few review articles are available in literature which describe about various biological activities of naphthyridines, but there is no comprehensive compilation particularly for antiviral activities. Objectives: The objective of this review is to compile the literature on anti-viral activities of naphthyridine analogs. Methods: SciFinder, Google Scholar and PubMed database were searched with keyword naphthyridine and the references obtained were further sorted using keywords antihiv, antiviral and virus, separately. References obtained were considered to review the antiviral literature of naphthyridines. Results: Literature search using SciFinder database with different keywords gave several references. Only references of antiviral activities of naphthyridine compounds were reviewed. References to in-silico studies alone or on formulation development or on patents were excluded. Conclusion: This review will be helpful for future researches to design and synthesize naphthyridine analogs with improved antiviral activities.

Related Products of 106-49-0, In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 106-49-0, Name is p-Toluidine, SMILES is NC1=CC=C(C)C=C1, belongs to naphthyridine compound. In a article, author is Wu, Gao Fen, introduce new discover of the category.

Two 1,8-naphthyridine-based N,O-chelated boron complexes (1 and 2) were designed as novel phosphate ion (Pi) probes, which are based on a methoxy oxalyl group reaction site. These two probes showed high selectivity for Pi detection without interference from ATP, PPi, or other anions. Dramatic color changes from colorless to light yellow were observed by addition of Pi to solutions of 1 and 2 in DMSO/HEPES buffer (0.02 M, pH 7.4) (V/V = 8:2). This qualitative color shift was accompanied by red-shifts in the UV-vis absorbance spectrum of approximately 43 nm for 1 and 46 nm for 2. Fluorescence quenching was observed in solutions of I (Phi = 0.31) and 2 (Phi = 0.23) upon addition of Pi. Probes 1 and 2 are the first two 1,8-naphthyridine-based boron complexes developed which serve as colorimetric probes capable of highly selective detection of Pi over other phosphate-based chemical species including P2O74-, ATP, ADP, AMP, GTP, GDP, GMP, UP, TDP, TMP, UTP, UDP, and UMP. The in vivo imaging results demonstrate that 1 and 2 are able to permeate into the HeLa cells and Caenorhabditis elegans to detect Pi via a strong fluorescence intensity change.
