The reaction of the 3-oxo-N,3-diphenylpropan-amide (3) with either malononitrile or ethyl cyanoacetate in ammonium acetate gave the 1,2-dihydropyridine derivatives 6a or 6b, respectively. On the other hand, carrying the same reaction in the presence of triethylamine gave the 1,6-dihydropyridine derivatives 7a and 7b, respectively. Moreover, compound 3 reacted with 2-aminoprop-1-ene-1,1,3-tricarbonitrile to give the pyridine derivative 9. Compound 7b reacted with the active methylene derivatives 10a,b and 4a,b to give the naphthyridine derivatives 11a,b and 12a,b; respectively. Compound 3 was also used for the synthesis of thiophene derivatives 13a,b and 16a,b. In addition, the reaction of ethyl benzoylacetate (1) with o-phenylene diamine gave the benzimidazole derivative 18. The reactivity of the latter product towards different reagents was studied to give different products. The cytotoxicity of the newly synthesized products was studied towards some cancer and normal cell lines, in addition toxicity of compounds was measured and docking of the most active compounds was done. Compounds 6b, 7b, 9, 13a, 13b, 16a, 20b, 20c, 24b, 25 and 26b exhibited optimal cytotoxic effect against cancer tested cell lines. These active compounds were evaluated against c-Met kinase using foretinib as the reference drug where all compounds expressed higher activity than the reference drug.

Complexation of 1,8-naphthyridine(Np)-2-carboxylic derivatives L-1-L-3 [L-1 = Np-2-COOH, L-2 = Np-2-CONH2, L-3 = Np-2-CONHCH2Py] with [Ir(COD)(mu-OMe)](2) yielded the corresponding complexes [Ir(COD)(L-n)] (1 similar to 3, n = 1 similar to 3, respectively). The potential tridentate L-3 behaves as a bidentate donor in the complex 3. Treatment of L-1 with [Ir(COD)Cl](2) under nitrogen atmosphere gave a Ir(III) hydride complex [Ir(COD)(L-1)HCl] (4). However, carrying out the reaction in the presence of oxygen rendered a Ir(III) dichloride species [Ir(COD)(L-1)Cl-2] (5). All these complexes were characterized by spectroscopic analyses and X-ray single crystal determination. Catalytic activity of iridium complexes in amination of amines with alcohols was screened. It appears that iridium amido complexes 2 and 3 show excellent catalytic activity on amination of anilines with alcohols in the presence of Cs2CO3 at 120 degrees C.

In a document, author is Arslan, Barn Seckin, introduce the new discover.

A new series of D-pi-A organic dyes bearing fused dibenzo[b,h] [1,6]naphthyridine as the conjugated pi-bridge, a cyanoacrylic acid moiety as the electron acceptor/anchoring group and different electron donor groups such as trimethoxy (5a), methoxy (5b) and dimethylamino (5c), were designed and synthesized for dye-sensitized solar cells (DSSCs), for the first time. The effect of donor groups on the performance of the DSSCs was systematically investigated using optical, electrochemical, theoretical and photovoltaic methods. Compared to dyes 5a and 5b, 5c showed a broader and more red-shifted absorption spectrum due to stronger electron donating ability of dimethylamino moiety, which is beneficial for absorbing more photons and thus generating high photocurrent, As a result, the DSSC fabricated with dye 5c has the highest power conversion efficiency of 5.02% (similar to 60% relative to N719-based standard cell), which is greater than those obtained by 5a and 5b-sensitized solar cells (3.22% and 2.13%, respectively) under standard air mass 1.5 global (AM 1.5 G) conditions. The improved photovoltaic performance mainly came from better photocurrent, as also confirmed by IPCE measurements. These results suggest that dibenzo[b,h] [1,6]naphthyridine pi-bridge bearing a strong electron donor group is a promising candidate to construct effective D-pi-A organic dyes for DSSCs.

With the aim of evaluating interaction between double-stranded calf thymus (ds)DNA and sulphur containing fused planar rings, the derivatives of 1,8-naphthyridine containing thiono groups were synthesized by the condensation of 2-mercapto-3-formyl[1,8]naphthyridines using 1-chloroacetone, 2-chloroacetamide, chloroaceticacid, and 2-chloro-1-phenylethanone in the presence of anhydrous potassium carbonate as s catalyst under solvent free microwave irradiation. The structures of the compounds were elucidated on the basis of elemental analysis, IR, H-1 NMR, and mass spectra. The interaction of thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (TNC) (3a) with ct-DNA was studied by UV-Vis spectrophotometry, viscosity, thermal denaturation, as well as cyclic voltammetry experiments. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometric measurements indicated a binding constant of K-b = 2.1 x 10(6) M-1. The thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (3a) increases the viscosity of sonicated rod-like DNA fragments. The binding of TNC to DNA increased the melting temperature by about 4 degrees C. The decrease in peak current heights and shifts of peak potential values are observed by the addition of calf thymus DNA in cyclic voltammetry studies.

We report a synthesis of 37 new 1,8-naphthyridine based compounds having a non-planar bicyclic moiety (bicyclo[3.3.1]nonane, bicyclo[3.3.0]octane and camphor). We measured energetic characteristics (E-Homo= [-5.9; -5.4] eV, E-LUMO = [-3.4; -2.4] eV and E-g_opt = [2.3; 3] eV), tested photoluminescence (PL) properties in chloroform solution (PL peaks at 390-490 nm range; QY reaching 53%) and produced multilayer OLED structures with our new materials as an emissive layer (EML). With changing the EML material, we observed electroluminescence (EL) covering a wide colour spectrum: red-orange, yellow, lettuce-green, green, blue-green (compared to violet from a control device). A broad white EL spectrum was registered for OLEDs with duplex non-planar V conformation molecules as an EML. The analysis of the results let us obtain precious information about the influence of molecular structure peculiarities on PL and EL spectra, as well as on values of the HOMO, the LUMO and E-g_opt, that are universal for all molecular systems.

In the present work three chromeno naphthyridine derivatives (CNs) have been synthesized using one pot multicomponent reaction of 2, 4-hydroxyacetophenone, aromatic aldehydes and malononitrile in water using silica gel as a catalyst. The simulated LDse values for the synthesized compounds are 340 mg/kg (CN-1), 1500 mg/kg (CN-2) and 800 mg/kg (CN-3) which suggest their non-toxic and eco-friendly nature The performance all the three compounds as corrosion inhibitors in 15% HCl on N80 has been analyzed via weight loss, electrochemical, surface characterization, and density functional theory (DFT) methods. Chromeno naphthyridine (CN-1) shows maximum inhibition efficiency of 98.3% at only 300 mg/L The measurement of EIS reveals the process of inhibition of corrosion is governed by control of charge transfer. The mixed nature of CNs adsorption is suggested by results of PDP. Langmuir model of adsorption shows the perfect fitting. Adsorption of CNs onto the metal surface was supported by MR. AFM, and UV-vis. Computational modelling using DFT data reveals that corrosion inhibition takes place by adsorption of both neutral and protonated forms on steel surface. Molecular dynamic simulation (MDS) suggests the parallel adsorption of CNs molecules both in neutral and protonated forms. (C) 2020 Elsevier B.V. All rights reserved.

Routine detection of trace amounts of Pb2+ is of significant importance because it poses severe risks to human health and the environment. In this paper, a novel label-free fluorescence platform for the sensitive detection of Pb2+ has been successfully constructed by using Pb2+-specific 8-17 DNAzyme as the molecular recognition element, 2-amino-5,6,7-trimethyl-1,8-naphthyridine (ATMND) as the signal reporter, and exonuclease III (Exo III) as the signal amplifier. A good linearity between the fluorescence intensity and the logarithm of Pb2+ concentration was obtained in the range from 100 pM to 10 M with a correlation coefficient (R-2) of 0.99. The sensing system exhibited ultrasensitivity towards Pb2+ at low concentration (50 pM) without any labeling, modification, immobilization, or washing procedure. Besides, the proposed method was also highly selective for Pb2+ against other metal ions. This biosensor was robust and can be applied for the determination of Pb2+ in complex samples with desired recovery and good accuracy. With the successful demonstration of Pb2+ detection, the label-free biosensor can be readily expanded to monitor other targets in a simple, cost-effective, and ultrasensitive way by replacing the target-specific molecular recognition elements.
