Synthesis and crystal structure of (1,8-naphthyridine-kappa N-2,N ‘)[2-(1H-pyrazol-1-yl)phenyl-kappa N-2(2),C-1]iridium(III) hexafluoridophosphate dichloromethane monosolvate

The solvated title salt, [Ir(C9H7N2)(2)(C8H6N2)]PF6 center dot CH2Cl2, was obtained from the reaction between 1,8-naphthyridine (NAP) and an orthometalated iridium(III) precursor containing a 1-phenylpyrazole (ppz) ligand. The asymmetric unit comprises one [Ir(ppz)(2)(NAP)](+) cation, one PF6- counter-ion and one CH2Cl2 solvent molecule. The central Ir-III atom of the [Ir(ppz)(2)(NAP)](+) cation is distorted-octahedrally coordinated by four N atoms and two C atoms, whereby two N atoms stem from the NAP ligand while the ppz ligands ligate through one N and one C atom each. In the crystal, the [Ir(ppz)(2)(NAP)](+) cations and PF6- counter-ions are connected with each other through weak intermolecular C-H center dot center dot center dot F hydrogen bonds. Together with an additional C-H center dot center dot center dot F interaction involving the solvent molecule, a three-dimensional network structure is formed.

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 38002-45-8 help many people in the next few years. Computed Properties of C6H11BrSi.

Compound 8b showed the highest inhibition activity against HepG2 cell line (IC50 equals 3.2 mu g/mL) among all tested compounds. The results were compared to 5-Fluorouracil (5-FU) and doxorubicin as reference drugs, (IC50 5 and 3.56 mu g/mL). Furthermore, molecular docking of compounds 3b, 6a, and 8b into the binding site of topoisomerase II was carried out. The results of the binding energy scores of these compounds were compared to the docking score of Vosaroxin, a known 1,8-naphthyridine derivative which is in clinical trials as potential anticancer drug. Compound 8b docking result revealed that it is the only tested compound that intercalate with DNA segment of the topoisomerase II, similar to Vosaroxin which was used as reference drug for docking comparison.

Synthesis of furo[2,3-c]-2,7-naphthyridine derivatives via domino heterocyclization reaction

2-Amino-4-cyanomethyl-6-dialkylamino-3,5-pyridinedicarbonitriles were found to react with substituted oxiranes yielding 5,6-diamino-8-dialkylamino-1,2-dihydrofuro [2,3-c]-2,7-naphthyridine-9-carbonitriles. The oxirane ring was shown to be opened selectively from the unsubstituted side and further cyclization occurred with participation of 3-CN, but not 5-CN of the starting pyridines. The furonaphthyridines obtained were converted into 2-dialkylamino-5-methyl-9,10-dihydro-4H-furo[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-l-carbonitriles and 2-dialkylamino-5,6,9,10-tetrahydro-4H-spiroffuro[2,3-c]pyrimido[4,5,6-ij]-2,7-naphthyridine-5,1′-cyclohexane}1-carbonitriles by treatment with acetic anhydride and cyclohexanone, respectively.

Synthesis, optical characterization, and TD-DFT studies of novel mero/bis-mero cyanine dyes based on N-bridgehead heterocycles

Novel mero/bis-mero cyanine dyes based on N-bridgehead imidazo[1,2-g] quinolino[2,1-a][2,6] naphthyridine have been synthesized and characterized to evaluate intramolecular charge transfer (ICT) effect on the energy gap (E0-0). The UV-vis and emission spectral studies revealed that dyes are absorbed in the region of lambda(max) 485-577 nm and emitted at 567-673 nm. Their solvatochromic behavior in solvents of various polarities, CCl4, C6H6, H2O, CHCl3, acetone, and DMF, was studied to emphasize the effect of solvent polarity on the absorption maxima, molar extinction coefficients of the dyes, and excitation energy of the dyes. Their electron cloud delocalization in HOMO/LUMO levels were studied by DFT using Gaussian 09 software. Time-dependent density functional theory (TD-DFT) was applied to theoretically explore the first excitation energy (E0-0) of these dyes, which was in good agreement with experimental results.

Aromatic Helical Foldamers as Nucleophilic Catalysts for the Regioselective Acetylation of Octyl beta-d-Glucopyranoside

Two indolocarbazole-naphthyridine foldamers 2 and 3 that fold into helical conformations were prepared. The 4-(N,N-dimethylamino)pyridine (DMAP) moiety was introduced at one end of the foldamer strands to develop foldamer-based catalysts for the site-selective acylation of polyols. These foldamers adopt helical conformations containing internal cavities capable of binding octyl beta-d-glucopyranoside. The association constants were determined to be 1.9 (+/- 0.1)x10(5) M-1 for 2 and 2.1 (+/- 0.1)x10(5) M-1 for 3 in CH2Cl2 at 25 degrees C. In the presence of DMAP, 2 or 3 as the catalysts, octyl beta-d-glucopyranoside was subjected to acetylation under identical reaction conditions. The DMAP-catalysed reaction afforded the random distribution of the monoacetylates (6-OAc : 4-OAc : 3-OAc : 2-OAc=33 : 24 : 41 : 2). In contrast, foldamers 2 and 3 led to the predominant formation of 6-OAc. The relative distributions were estimated to be 6-OAc : 4-OAc : 3-OAc=88 : 4 : 6 : similar to 0 with 2 and 6-OAc : 4-OAc : 3-OAc : 2-OAc=90 : 3 : 6 : 1 with 3.

Molecular Dynamics Simulation Study of Binding Affinity of Thieno[2,3-b]benzo[1,8] naphthyridine Derivatives to DNA

DNA binding position and binding affinity of drugs are important information that helps medicinal chemists in synthesis of new drugs. We used molecular docking and molecular dynamics simulation to reveal binding strength of thieno[2,3-b]benzo[1,8]naphthyridine derivatives to DNA. Molecular docking showed that molecules with more steric hindrance select groove position in DNA structure. Other molecules are intercalated between base pairs of GC and AT. Restrained electrostatic potential (RESP) charges, root mean square deviation (RMSD), and total potential analyses were performed. RMSD and total potential analyses showed that all simulations have stability for MMGBSA analysis. Binding affinity of all drugs was derived via MMGBSA analysis. Thermodynamics analysis showed that binding affinity of groove binding drugs is less than that of intercalating ones. Also, it was found that a linear relationship exists between RESP charges and Delta G (pred). Additionally, our results demonstrated the highest affinity for molecules carrying substituent groups of-OCH3 and-CH3.

A practical, convenient, and safe cyano(nitro)methylation method was developed, in which cyano-aci-nitroacetate served as a synthetic equivalent of anionic nitroacetonitrile. A control of the single/double Michael additions was achieved, which enabled the synthesis of unsymmetrical double Michael adducts. Moreover, the Michael adducts can be used as precursors of pyridine and naphthyridine frameworks. (C) 2014 Elsevier Ltd. All rights reserved.

Reaction of isatin-1-acetamides with alkoxides: Synthesis of novel 1,4-dihydro-3-hydroxy-4-oxo-2-quinolinecarboxamides

The study of the reactivity of a series of isatin-1-acetamides with hot alkoxides is described. These reactions lead to 1,4dihydro-3-hydroxy-4-oxo-2-quinolinecarboxamides as main products, and 3-hydroxy-2-oxindoles as well as other minor products. Experimental results indicate that the starting compounds undergo transformation through two principal routes: ring expansion of isatin leading to quinoline carboxamides, probably as the result of a ring-opening and ring-closure rearrangement, and reduction of the keto carbonyl group due to the reductive ability of alkoxides.
