Synthesis and X-ray structures of two discrete metal complexes of 2,2 ‘-bi-1.5-naphthyridine, a new ambivergent ligand

A new synthesis of 2,2’-bi-1,5-naphthyridine (1) is described along with its reactions with copper(II) nitrate, silver(l) tetrafluoroborate and palladium(11) chloride. X-ray crystal structures are described of a mononuclear copper complex, in which 1 acts as a convergent ligand chelating through the two internal nitrogens, and an unusual M4L3 silver complex containing both two- and three-coordinate silvers and with ligand I acting in two different bridging modes.

Construction of new heteroacenes based on benzo[b]thieno[2,3-d] thiophene / quinoline or 1,8-naphthyridine systems using the Friedlander reaction

Two new classes of heteroacenes, namely benzo[4′,5′]thieno[2′,3′:4,5]thieno[3,2-b]quinolines and benzo [4′,5′]thieno[2′,3′:4,5]thieno[3,2-b][1,8]naphthyridines, have been formed using the Friedlander reaction to annulate the benzo[b]thieno[2,3-d]thiophene scaffold to quinoline or 1,8-naphthyridine fragments. In accordance with this synthetic strategy, benzo[b]thieno[2,3-d]thiophen-3(2H)-ones were treated with 2-aminobenzaldehydes or 2-aminonicotinaldehyde in the presence of pyrrolidine in glacial acetic acid at reflux to give the desired quinoline- or 1,8-naphthyridine-fused compounds, respectively. The optical and electrochemical properties of selected heteroacenes were determined. (C) 2019 Elsevier Ltd. All rights reserved.

New polynuclear 1,5-naphthyridine-silver(I) complexes as potential antimicrobial agents: The key role of the nature of donor coordinated to the metal center

New polynuclear silver(I) complexes with 1,5-naphthyridine (1,5-naph), [Ag(NO3)(1,5-naph)](n) (Ag1), [Ag (CF3COO)(1,5-naph)]n (Ag2) and [Ag(CF3SO3)(1,5-naph)](n) (Ag3) were synthesized by the reaction of the corresponding silver(I) salt and 1,5-naph in ethanol at room temperature. These complexes were characterized by NMR, IR and UV Vis spectroscopy, while their crystal structures were determined by single-crystal X-ray diffraction analysis. In all these complexes, 1,5-naph acts as a bridging ligand between two Ag(I) ions, while the remaining coordination sites are occupied by oxygen atom(s) of the corresponding anion. The antimicrobial efficiency of these silver(I) complexes was evaluated against the broad panel of Gram-positive and Gram-negative bacteria and fungi. The complexes showed good to moderate antibacterial activity with the minimal inhibitory concentration (MIC) values being in the range 2.5-100 mu g/mL (6.5-333.3 mu M), while their antifungal activity against the investigated Candida spp. was significantly higher (MIC = 0.78-6.25 mu g/mL; 2.6-20.8 mu M). Moreover, complexes Ag1 and Ag2 effectively inhibited C. albicans biofilms formation, while Ag1 was also shown to inhibit the formation of mixed C. albicans/Pseudomonas aeruginosa biofilms. Toxicological evaluations on zebrafish (Dario rerio) embryos revealed that all silver(I) complexes could be applied as antifungal agents, whereas Ag3 had the best therapeutic potential showing both the lowest MIC values against the tested Candida strains and the non-toxic in vivo response in the zebrafish embryos at these doses.

1,5-Naphthyridine-based conjugated polymers as co-sensitizers for dye-sensitized solar cells

1,5-naphthyridine-based conjugated polymers (P1 and P2) were synthesized and extensively characterized by H-1 NMR, thermogravimetric analysis (TGA), FT-IR. These polymers were employed as co-sensitizers in DSSCs sensitized with Ru (II) based N3 dye. In comparison to the N3 sensitized device, the P1 and P2 co-sensitized solar cells demonstrated enhanced open circuit voltage, (V-OC) of 825 and 788 mV and better fill factor (FF) of 59 and 58%, respectively. The co-sensitization of P1 and P2 with N3 increased the overall efficiencies to 5.88% and 6.21%, respectively, as compared to 5.58% for N3 sensitizer alone. The fabricated device based on N3 co-sensitized with P2 displayed higher charge recombination resistances as compared to the devices based on N3 alone or N3 co-sensitized with P1. The conjugated polymers are believed to enhance light harvesting ability and reduce the charged recombination in the co-sensitized solar cells.

Synthesis of Naphthyridine Dimers with Conformational Restriction and Binding to DNA and RNA

One of the important determinants in the efficiency of a molecular interaction is the necessity for conformational changes in host and/or guest molecules upon binding. In small-molecule interactions with nucleic acids, conformational changes on both molecules are often involved, especially in intercalating binding. Mismatch binding ligands (MBLs) we described here consist of two heterocycles that predominantly exist in one conformation, so it is of interest to determine if such molecules can bind to any DNA and RNA structures. One molecule, 1-NHR, which predominantly exists as the unstacked conformation in aqueous solvent, has been successfully synthesized and characterized. Compound 1-NHR did not efficiently bind to GX/Y DNA and RNA sequences, but the binding pattern is different from that of authentic MBL naphthyridine carbamate dimer. In vitro selection of RNA that specifically binds to 1-NHR was performed from pre-miR-29a loop library RNA, and one RNA, to which 1-NHR bound with high affinity, has been successfully identified. Although it was anticipated that 1-NHR, with a predominantly unstacked conformation, would show entropy-driven binding, isothermal titration calorimetry analysis suggested that the binding of 1-NHR to RNA was enthalpy driven with an apparent K-d of about 100nm.
