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.

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.

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.

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.

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.

Nine supramolecular assemblies from 5,7-dimethyl-1,8naphthyridine-2-amine and carboxylic acids by strong classical H-bonds and other noncovalent associations

This article demonstrates 5,7-dimethyl-1,8-naphthyridine-2-amine based organic salt formation in nine crystalline solids 1-9, in which the carboxylates have been integrated. Addition of equivalents of the COOH to the solution of 5,7-dimethyl-1,8-naphthyridine-2-amine generates the singly protonated cationic species which direct the carboxylates. The nine compounds crystallize as their organic salts with the COOH proton transferred to the aromatic N of the 5,7-dimethyl-1,8-naphthyridine-2-amine. All salts have been characterized by IR, mp, EA and XRD technique. The major driving force in 1-9 is the classical H-bonds from 5,7-dimethyl-1,8-naphthyridine-2-amine and the acids, here the N N-H…O H-bonds were found in all salts. Other extensive non-covalent interactions also exhibit great functions in space association of the molecular counterparts in relevant crystals. Except 4, all salts had the CH-O, or CH3-O interactions or both. Except 9, the common R-2(2) (8) graph set has been observed in all salts due to the H-bonds and the non-covalent associations. For the synergistic interactions of the classical H-bonds and the various non-covalent associations, the salts displayed 1D-3D structures. (C) 2017 Elsevier B.V. All rights reserved.

High-efficiency thermally activated delayed fluorescence emittersviaa high horizontal dipole ratio and controlled dual emission

Thermally activated delayed fluorescence (TADF) emitters containing 1,5-naphthyridine as an electron acceptor and phenoxazine and phenothiazine as electron donors, namely, 2,6-bis(4-(10H-phenoxazin-10-yl)phenyl)-1,5-naphthyridine (NyDPO) and 2,6-bis(4-(10H-phenothiazin-10-yl)phenyl)-1,5-naphthyridine (NyDPt), were developed. Because of the linear molecular structures,NyDPOandNyDPtshowed high horizontal emitting dipole ratios of 81% and 84%, respectively. Furthermore,NyDPOandNyDPtexhibited TADF characteristics with photoluminescence quantum yields (PLQYs) of 79% and 45%, respectively. In particular,NyDPtshowed dual photoluminescence (PL) emission from quasi-axial and quasi-equatorial conformers. However, only quasi-equatorial emission was observed in the organic light-emitting diode (OLED) at low current density, resulting in a high device efficiency despite a low PLQY. OLED devices based onNyDPOandNyDPtexhibited high external quantum efficiencies of 29.9% and 25.8%, and maximum luminance values of 33 540 cd m(-2)and 14 480 cd m(-2), respectively.

3D-QSAR and Docking Studies of N-hydroxy 1,8-naphthyridine 2-one Analogs as Ribonuclease H Inhibitors

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.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 82-76-8 help many people in the next few years. Category: naphthyridines.
