Aerobic oxidative coupling of alcohols and amines towards imine formation by a dicopper(I,I) catalyst

A dicopper(I,I) complex [Cu-2(L-1) (Cl)(2)] (1), bearing a Cu2Cl2 core spanned by a naphthyridine-diimine ligand is synthesized by the treatment of CuCl with 2,7-bis(N-mesitylmethylimino)-1,8-naphthyridine (L-1). The catalytic efficacy of 1 is assessed for aerobic oxidative synthesis of imines from alcohols and amines. The title complex is found to be an excellent catalyst for a wide variety of alcohols and amines. Kinetic experiments revealed the involvement of both copper ions in the aerobic oxidation process. The general utility of naphthyridine based ligands to favour a possible bimetallic pathway for a catalytic reaction is demonstrated here. (C) 2017 Elsevier B.V. All rights reserved.

Straightforward synthesis and biological evaluation as topoisomerase I inhibitors and antiproliferative agents of hybrid Chromeno[4,3-b][1,5]Naphthyridines and Chromeno[4,3-b][1,5]Naphthyridin-6-ones

This work describes the synthesis of hybrid tetrahydro-1,5-naphthyridine and 1,5-naphthyridine derivatives fused with heterocycles such as chromenes and chromen-2-ones or coumarins, which were synthesized in good to high general yields. The synthetic route involves an intramolecular [4 + 2]-cycloaddition reaction of functionalized aldimines obtained by the condensation of 3-aminopyridine and aldehydes containing a double or triple carbon-carbon bond in orto position and allows the selective generation of three stereogenic centers in a short, efficient and reliable synthesis. The subsequent dehydrogenation of the fused tetrahydrochromeno[4,3-b][1,5]naphthyridines and/or tetrahydrochromeno[4,3-b][1,5]naphthyridin-6-ones leads to the formation of the corresponding tetracyclic chromeno[4,3-b][1,5]naphthyridine derivatives anclior chromeno[4,3-b][1,5]naphthyridin-6-ones in quantitative yields. Some of the prepared products showed activity as inhibitors of Topoisomerase I (TopI). Additionally, the cytotoxic behavior of these compounds has been studied in cell lines derived from human lung adenocarcinoma (A549) and human ovarian carcinoma (SKOV03), and on noncancerous lung fibroblasts cell line (MRCS) where, on the last ones, the absence of cytotoxicity was observed. 7-Phenyl-6H-6a,7,12,12a-tetrahydrochromeno[4,3-b][1,5]naphthyridine 5a showed excellent cytotoxic activity with a IC50 value of 1.03 +/- 0.30 mu M against the A549 cell line and a IC50 value of 1.75 +/- 0.20 mu M against the SKOV03 cell line. The obtained results point to these compounds as good antiproliferative candidates. (C) 2019 Elsevier Masson SAS. All rights reserved.

One-pot solvent free synthesis and DNA binding studies of thieno[2,3-b]-1,8-naphthyridines

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.

Synthesis of 1,8-Naphthyridines and Their Application in the Development of Anionic Fluorogenic Chemosensors

Two 1,8-naphthyridines were synthesized and found to be fluorescent in solution. These compounds were studied in the presence of Cu+ and Cu2+ ions and it was verified that the metal causes the quenching of their fluorescence emission, due to the formation of complexes between the naphthyridine and the metal. A displacement assay was carried out in a DMSO-water mixture with the addition of various anions to the solutions of the complexes, and it was observed that these systems have a high capacity to selectively detect cyanide.

Discovery of Imidazo[1,2-alpha][1,8]naphthyridine Derivatives as Potential HCV Entry Inhibitor

RO8191 represents a newly discovered small-molecule IFN-like agent that displays potent anti-HCV activity. With it as lead, a series of compounds bearing an imidazo[1,2-alpha][1,8]naphthyridine core and an amide bond-linked side chain were designed and synthesized. These compounds were evaluated on HCV cell culture system (HCVcc-hRluc-JFH1), and some of them exhibited remarkable anti-HCV activity (EC50 = 0.017-0.159 mu M) and low toxicity (CC50 > 25 mu M). Moreover, it was revealed that these newly identified anti-HCV agents exert their antiviral effect through a distinct mechanism of action from that of RO8191 by targeting the viral entry process. Thus, our study provides a starting point for the development of potential HCV entry inhibitor.
