Naphthyridine-BF2 complexes with an amide-containing di-2-picolylamine receptor: Synthesis, structures and photo-induced electron transfer

Two novel naphthyridine-BF2 compounds with an amide-containing di-2-picolylamine (DPA) receptor, namely 4 and 5, were synthesized and structurally characterized by various spectroscopic techniques and X-ray diffraction crystallography. The crystal structures of both mononuclear 4 and dinuclear 5 possessed a N,O-chelated naphthyridine-BF2 core, and the second BF2 unit in 5 was ligated to a basic amido N-atom together with a tertiary amine in the DPA part. The spectroscopic properties of 4 and 5 were investigated in various solvents and the difference between them was rationalized by the intramolecular charge transfer (ICT) and photo-induced electron transfer (PET) mechanism. Cyclic voltammetry measurements and theoretical calculations were carried out, and the results were in agreement with their spectral data. (C) 2013 Elsevier B.V. All rights reserved.

Structure-guided design, synthesis and biological evaluation of novel DNA ligase inhibitors with in vitro and in vivo anti-staphylococcal activity

A series of 2-amino-[1,8]-naphthyridine-3-carboxamides (ANCs) with potent inhibition of bacterial NAD+-dependent DNA ligases (LigAs) evolved from a 2,4-diaminopteridine derivative discovered by HTS. The design was guided by several highly resolved X-ray structures of our inhibitors in complex with either Streptococcus pneumoniae or Escherichia coli LigA. The structure-activity-relationship based on the ANC scaffold is discussed. The in-depth characterization of 2-amino-6-bromo-7-(trifluoromethyl)-[1,8]-naphthyridine-3-carboxamide, which displayed promising in vitro (MIC Staphylococcus aureus 1 mg/L) and in vivo anti-staphylococcal activity, is presented.

Synthetic Methods of Quinoline Derivatives as Potent Anticancer Agents

Background: On account of significant biological activities, quinoline derivatives have drawn more attention to the synthesis and biological activities in the search for new therapeutic agents. Several new synthetic approaches have been implemented to derive new molecules from quinoline and all the synthesized molecules showed effective anticancer activity. Method: Some molecules are synthesized using quinolones as precursor reactant, which is another effective product of quinoline, also showing significant activity against malignant tumors. The presence of nitrogen in it and its ability to bind with enzymes like gyrase, topoisomerase II and kinase have also proven it with antitumor activity. Conclusion: This review encapsulates the recent advances in the synthesis and anticancer activity of Quinoline derivatives.

Naphthyridine-based thermally activated delayed fluorescence emitters for multi-color organic light-emitting diodes with low efficiency roll-off

Three new 1,8-naphthyridine-based thermally activated delayed fluorescence (TADF) emitters, 2,7-di(9,9-dimethylacridin-10(9H)-yl)-1,8-naphthyridine (DMAC-ND), 2,7-di(10H-phenothiazin-10-yl)-1,8-naphthyridine (PTZ-ND) and 2,7-di(10H-phenoxazin-10-yl)-1,8-naphthyridine (PXZ-ND), were designed and synthesized. They possessed twisted structures and small Delta E-ST, which could make them show excellent TADF and AIDF properties. Consequently, multi-color organic light-emitting diodes (OLED) based on emitters DMAC-ND, PTZ-ND and PXZ-ND were fabricated, which could achieve a maximum external quantum efficiency (EQE) of 14.1, 13.4 and 13.0%, respectively. Moreover, all devices exhibited relatively low turn-on voltages and low efficiency roll-off ranging from 4.5% to 20% at the luminance of 1000 cd m(-2) probably owing to the microsecond-scale delayed photoluminescence (PL) and AIDF properties of the emitters. Notably, a DMAC-ND-based non-doped device reached the luminance of 20000 cd m(-2) easily at the voltage of 6.5 V, and exhibited very low efficiency roll-off of 4.5% at the luminance of 1000 cd m(-2) and 33.6% at the luminance of 10000 cd m(-2).

Structural and spectroscopic study of the asymmetric 2-(2′-pyridyl)-1,8-naphthyridine ligand with closed-shell metals

Herein, we report the synthesis and characterization of a series of complexes of the asymmetric ligand 2-(2′-pyridyl)-1,8-naphthyridine (pyNP, 1) with different closed-shell metals. For the first time ligand pyNP has been structurally and vibrationally characterized. The geometry of the pyNP ligand, with 3 N donor sites, can favor metallophilic interaction in complexes, so we performed a study on its coordination chemistry with different metals (Ag(I), Hg(II) and Pb(II)). Twelve new complexes, namely [Ag-2(pyNP)(2)(NO3)(2)] (2), [Hg(pyNP)X-2](X = Cl(3), Br(4), l(5), CN(6), SCN(7, 8)), [Pb(pyNP)(2)(NO3)(2)] (9), [Pb (pyNP)(NO3)(2)](2) (10), [Cu(pyNP)Cl-2(H2O)] (11), [Cu(pyNP)(2)(H2O)[Hg-2(CN)(4)Cl-2]-H2O (12) and [Cu(pyNP) (H2O)(2)(mu-CN)Hg-2(CN)(3)Cl-2]-H2O (13), have been synthesized and characterized by single crystal X-ray diffraction, Raman, FTIR and electronic spectroscopies. Structure of complex 2 shows a supported argentophilic interaction, and is the first structure in which pyNP bonds two previously unbounded metal centers. (C) 2017 Elsevier Ltd. All rights reserved.

A Dinickel Catalyzed Cyclopropanation without the Formation of a Metal Carbene Intermediate

(NDI)Ni-2 catalysts (NDI=naphthyridine-diimine) promote cyclopropanation reactions of 1,3-dienes using (Me3Si)CHN2. Mechanistic studies reveal that a metal carbene intermediate is not part of the catalytic cycle. The (NDI)Ni-2(CHSiMe3) complex was independently synthesized and found to be unreactive toward dienes. Based on DFT models, we propose an alternative mechanism that begins with a Ni-2-mediated coupling of (Me3Si)CHN2 and the diene. N-2 extrusion followed by radical C-C bond formation generates the cyclopropane product. This model reproduces the experimentally observed regioselectivity and diastereoselectivity of the reaction.

If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 573-17-1, in my other articles.
