Recent advances in DNA gyrase-targeted antimicrobial agents

Antimicrobial resistance is one of the greatest challenges facing the world today. In the United States alone, it is responsible for the death of more than 20,000 people each year. DNA gyrase, a well-validated drug target, is involved in bacterial DNA replication, repair and decatenation. Currently, the fluoroquinolone class of antibacterials act via inhibition of the DNA gyrase enzyme. However, their efficacy is hindered by the increasing incidence of antimicrobial resistance. Therefore, in this review, we provide an account regarding the structure of DNA gyrase and quinoline and non-quinolone inhibitors published within the last five years (2015-2019). Further, we also discuss molecular interactions and structureactivity relationship studies of the published inhibitors. (C) 2020 Elsevier Masson SAS. All rights reserved.

Identification of a novel class of selective Tpl2 kinase inhibitors: 4-alkylamino-[1,7]naphthyridine-3-carbonitriles

We have previously reported the discovery and initial SAR of the [1,7]naphthyridine-3-carbonitriles and quinoline-3-carbonitriles as Tumor Progression Loci-2 (Tp12) kinase inhibitors. In this paper, we report new SAR efforts which have led to the identification of 4-alkylamino-[1,7]naphthyridine-3-carbonitriles. These compounds show good in vitro and in vivo activity against Tp12 and improved pharmacokinetic properties. In addition they are highly selective for Tp12 kinase over other kinases, for example, EGFR, MEK, MK2, and p38. Lead compound 4-cycloheptylamino-6-[(pyridin-3-ylmethyl)-amino]-[1,7]naphthyridine-3-carbonit-rile (30) was efficacious in a rat model of LPS-induced TNF-alpha production. (C) 2007 Elsevier Ltd.

Systematic investigation of 2,7-dihydroxy-1,8-naphthyridine dimerization – secondary interactions and tautomeric preferences calculations

The tautomeric preferences and dimer formation of 2,7-dihydroxy-1,8-naphthyridine have been investigated using MP2/6-31G(2d,p), M05/6-311+G(2d,p) and B3LYP/6-311+G(2d,p) computational methods. Both geometrical parameters and energetic data are indicative of the presence of secondary interaction (SI) in the dimer formation. Weak hydrogen bonds (HB) form a cooperative network of SI, while stronger hydrogen bonds compete. The magnitude of the secondary interactions are compared across all dimers. The influence of dimerization on geometry, energy and relative molecules position is discussed. (C) 2009 Elsevier B.V. All rights reserved.

Phosphotungstic Acid Catalyzed One Pot Synthesis of 4,8,8-Trimethyl-5-phenyl-5,5a,8,9-tetrahydrobenzo[b] [1,8]Naphthyridin-6(7H)-one Derivatives and Their Biological Evaluation Against A549 Lung Cancer Cells

A facile one pot multicomponent synthesis of 1,8-naphthyridinone derivatives was developed using a mild and reusable phosphotungstic acid catalyst. A 2-amino picoline, benzaldehyde derivatives and 1,3-dicarbonyl cyclohexane were used to synthesize 1,8-naphthyridinones, which was achieved by conventional heating under solvent-free conditions. All synthesized compounds were characterized by spectral analysis and screened for anticancer activity against A549 lung cancer cells. The results from the cell viability assay showed that the synthesized compounds do have a biological effect at various concentrations on the lung cancer cells. Compounds 4F-p-CF3 and 4H-VAN showed potential as an antiproliferative agent and a dose-dependent decline in cell viability was observed.

Environmentally friendly preparation of nanoparticles for organic photovoltaics

Aqueous nanoparticle dispersions were prepared from a conjugated polymer poly[thiophene-2,5-diyl-alt-5,10-bis ((2-hexyldecyl)oxy) dithieno[3,2-c:3′, 2′-h][1,5] naphthyridine-2,7-diyl] (PTNT) and fullerene blend utilizing chloroform as well as a non-chlorinated and environmentally benign solvent, o-xylene, as the miniemulsion dispersed phase solvent. The nanoparticles (NPs) in the solid-state film were found to coalesce and offered a smooth surface topography upon thermal annealing. Organic photovoltaics (OPVs) with photoactive layer processed from the nanoparticle dispersions prepared using chloroform as the miniemulsion dispersed phase solvent were found to have a power conversion efficiency (PCE) of 1.04%, which increased to 1.65% for devices utilizing NPs prepared from o-xylene. Physical, thermal and optical properties of NPs prepared using both chloroform and o-xylene were systematically studied using dynamic mechanical thermal analysis (DMTA) and photoluminescence (PL) spectroscopy and correlated to their photovoltaic properties. The PL results indicate different morphology of NPs in the solid state were achieved by varying miniemulsion dispersed phase solvent.

7-(2,2-Dimethylpropanamido)-2-methyl-1,8-naphthyridin-1-ium chloride monohydrate

The asymmetric unit of the title compound, C(14)H(18)N(3)O(+)center dot Cl(-)center dot H(2)O, comprises a substituted amido-naphthyridine cation, a chloride anion and a water molecule of crystallization. Intramolecular C-H center dot center dot center dot O hydrogen bonds generate six-membered rings, producing an S(6) ring motif. The amido group is twisted from the naphthyridine ring, making a dihedral angle of 17.65 (7)degrees. The crystal structure is stabilized by intermolecular N-H center dot center dot center dot O, N-H center dot center dot center dot Cl, O-H center dot center dot center dot Cl (x 2), and C-H center dot center dot center dot O (x 2) hydrogen bonds. These interactions linked neighbouring molecules into chains along the a and b axes of the crystal, thus forming molecular sheets parallel to the (001) plane.

Molecular modeling studies of novel naphthyridine and isoquinoline derivatives as CDK8 inhibitors

Cell cycle is an important part of cellular activities. The selective inhibition of cyclin-dependent kinases (CDK) activity in tumor cells can lead to continuous cell proliferation. Thirty-nine CDK8 inhibitors were systematically investigated on the basis of a three-dimensional quantitative structure-activity relationship (3D-QSAR). Models for comparative molecular field analysis (q(2)=0.64,r(2)=0.98) and comparative molecular similarity index analysis (q(2)=0.609,r(2)=0.952) were obtained. Contour maps illustrated that bioactivity of inhibitors is most affected by steric, electrostatic, hydrogen bond donor, and receptor interactions of molecular groups. Twenty new CDK8 inhibitors (DS01-DS20) were designed based on the contour maps. The results of ADME prediction illustrated that the designed compounds had potential druggability. The binding mode between a ligand and receptor was explored through molecular docking and molecular dynamics. Results revealed that the hydrogen bond interaction with residue LYS52 remarkably affected the activity of these compounds. Further analysis indicated that the introduction of fluorine to an amino naphthyridine ring of compound 28 contributes to the improvement of molecular activities. Pharmacophore-based virtual screening and Surflex-Sim in the ZINC database of 1,30,000 molecules demonstrated that 14 compounds with an indazole ring might be antitumor inhibitors. 3D-QSAR, molecular docking, molecular dynamics and pharmacophore results are consistent. These findings can be used as a reference for the design and discovery of new CDK8 inhibitors that can reduce design errors. Communicated by Ramaswamy H. Sarma

Synthesis and spectral characterization of a novel fluorescent functional monomer 2,4-dimethyl-7-acrylamine-1, 8-naphthyridine

A new fluorescent functional monomer DMAAN has been designed and synthesized for the first time. The monomer was expected to bind with cytosine via complementary hydrogen bonding under certain experimental conditions. The synthetic procedure of DMAAN is as follows. A suspension of 2,6-diaminopyridine in phosphoric acid was added to acetylacetone. The mixture was warmed for thirty minutes on a steam-bath. Then 2, 4-dimethyl-7-amino-1,8-naphthyridine (DMAN, mp 216-218 degrees C) was obtained. DMAAN was prepared by the reaction of DMAN with acryloyl chloride in chloroform and triethylether mixed solvent. Acryloyl chloride in anhydrous chloroform was added dropwise over 30 minutes with constant stirring at 4 degrees C. The melting point of the final product was 239-241 degrees C. Mass spectrometry and proton NMR were used to confirm the chemical structure of DMAN and DMAAN. The products were also characterized by UV and fluorescence spectrometry.
