We have achieved the synthesis of 1-aryl-2-substituted 4-oxoquinoline and 4-oxo-1,8-naphthyridine derivatives, which cannot be synthesized by known methods, via two useful synthons, 2-formyl-4-oxoquinoline and 2-methylsulfonyl-4-oxo-1,8-naphthyridine. We also succeeded in the synthesis of 1-aryl-3-fluoro-4-oxoquinoline by fluorocyclization of N-arylenaminone with Selectfluor (R) and potassium carbonate in DMF in a one-pot procedure. To the best of our knowledge, this is the first synthesis of 3-fluoro-4-oxoquinoline derivatives. We confirmed that these protocols were mutually applicable to the synthesis of 4-oxoquinoline and 4-oxo-1,8-naphthyridine derivatives.

In this study, we developed a donor-pi-acceptor-pi-donor-type thermally activated delayed fluorescence (TADF) emitter (NyDPAc) using 1,5-naphthyridine as a core moiety. NyDPAc exhibited a high horizontal dipole ratio and thus a high external quantum efficiency (20.9%) even at a relatively low photoluminescence quantum yield (57%). 1,5-naphthyridine as an electron acceptor represents a promising core moiety for efficient TADF materials.

Permanent porosity in lantern-type M(4)L(4)paddlewheel-based cages is rare and has only been reported for naphthalene, naphthyridine, and diethynylbenzene-based linkers. This work presents the design, synthesis, and characterization of small lanterns that exhibit CO(2)accessible BET surface areas in excess of 200 m(2)g(-1). The crystal packing and porosity of these cages can be tuned by either ligand functionalization or the choice of M(2+)source used in their synthesis. Given their low nuclearity, these cages with internal M-M distances of less than 5 angstrom represent the lower size limit for permanently microporous coordination cages.

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.

Three-dimensional quantitative structure activity relationship (3D-QSAR) studies were performed for a series of ribonuclease H inhibitors using comparative molecular field analysis (CoMFA), comparative molecular similarity indices analysis (CoMSIA) and docking studies. A large set of 33 different aromatic/heterocyclic N-hydroxy 1,8-naphthyridine 2-one analogs as Ribonuclease H inhibitors wher chosen for the present study. The naphthyridine ring of the n-hydroxy 1,8-naphthyridine 2-one gives the class of compounds which has the ability to chelate metal cations Mn2+ present in RNase H active. The conventional ligand-based 3D-QSAR studies were performed based on the low energy conformations employing database alignment rule. The ligand-based model gave q(2) values 0.663 and 0.512 and r(2) values 0.997 and 0.999 for CoMFA and CoMSIA respectively and the predictive ability of the model was also evaluated. The predicted r(2) values were 0.660 and 0.650 for CoMFA and CoMSIA, respectively. Docking studies were employed to bind the inhibitors into the active site to determine the probable binding conformation. N-hydroxy 1,8-naphthyridine 2-one binds an RNA: DNA substrate, the RT/RNA: DNA structure (PDB code: 1HYS) was superimposed on our RT/N-Hydroxy 1,8-Naphthyridine 2-one (3QLH) structure (residues Val442 to Asp443, Glu478, and Asp549). Present study indicates that the CoMFA and CoMSIA models along with molecular docking could be reliable to establish a suitable molecular model which may be used in the design of novel ribonuclease H inhibitors as leads.

The emergence of bacterial resistance against life-saving medicines has forced the scientific community and pharmaceutical industry to take actions in the quest for novel antibacterials. These should not only overcome the existing bacterial resistance but also provide at least interim effective protection against emerging bacterial infections. Research into DNA gyrase and topoisomerase IV inhibitors has become a particular focus, with the description of a new class of bacterial topoisomerase type II inhibitors known as novel bacterial topoisomerase inhibitors, NBTIs. Elucidation of the key structural modifications incorporated into these inhibitors and the impact these can have on their general physicochemical properties are detailed in this review. This defines novel bacterial topoisomerase inhibitors with promising antibacterial activities and potencies, which thus represent one potential example of the future drugs for bad bugs, as identified by the World Health Organization.

Two new copper(I) complexes [Cu(L-1)(2))PF6 (L-1 = 4-diphenylphosphino-1,5-naphthyridine, 1) and]Cu(L-2)(2)] PF6 (L-2 = 4-diphenylphosphino-8-methyl-1,5-naphthyridine, 2), have been prepared and characterized. 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.

An efficient and environmentally benign synthetic protocol has been developed for the synthesis of benzo[c]pyrazolo[2,7]naphthyridine derivatives through regioselective multi-component on-water reaction of isatin, malononitrile and 3-aminopyrazole. The Knoevenagel condensation of isatin with malononitrile resulted in the formation of arylidene, which subsequently underwent Michael addition with 3-aminopyrazole followed by basic hydrolysis, cyclization, decarboxylation and aromatization to give the target naphthyridines in good to excellent yields. The one-pot multi-component protocol was also employed to obtain the said naphthyridines in a lower yield (10-15%) than obtained by basic hydrolysis of spiro-intermediates. The present study shows attractive features such as the use of water as a green solvent, short reaction time, reduced waste products and transition metal free C-C and C-N bond formation. The structures of the synthesized derivatives were established through FTIR, H-1-NMR, C-13-NMR spectroscopy and ESI-mass spectrometry.

With the ever-increasing concerns on environmental pollution and energy crisis, it is of great urgency to develop high-performance photocatalyst to eliminate organic pollutants from wastewater and produce hydrogen via water splitting. Herein, a polypyridyl-based mixed covalent Cu-I/II complex with triangular {Cu-3} and rhombic {Cu2Cl4} subunits alternately extended by mixed SCN- and Cl- heterobridges [Cu-4(DNP)(SCN)Cl-4](n) (1) [DNP = 2,6-bis(1,8-naphthyridine-2-yl)pyridine] was solvothermally synthesized and employed as a dual-functional co-photocatalyst. Resulting from a narrowed band-gap of 1.07 eV with suitable redox potential and unsaturated Cu-I/II sites, the complex together with H2O2 can effectively degrade Rhodamine B and methyl orange up to 87.4 and 88.2%, respectively. Meanwhile, the complex mixed with H2PtCl6 can also accelerate the photocatalytic water splitting in the absence of a photosensitizer with the hydrogen production rate of 27.5 mu mol.g(-1).h(-1). These interesting findings may provide informative hints for the design of the multiple responsive photocatalysts.
