Synthesis, structures and spectroscopic properties of new 1,2-bis[2-(4-methyl-7-acetylamino-1,8-naphthyridine)]ethylene ligand and its binuclear copper(I) complexes

The synthesis, characterization, spectroscopic properties of a new ligand 1,2-bis[2-(4-methyl-7-acetyl-amino-1,8-naphthyridine)]ethylene (L) and its two binuclear Cu(I) complexes containing triphenylphosphine (PPh3) or bis(diphenylphosphino)methane (dppm), [Cu-2(L)(PPh3)(4)](BF4)(2)center dot 2CH(2)Cl(2) (1 center dot 2CH(2)Cl(2)) and [Cu-2(L)(dppm)(2)](BF4)(2)center dot 4H(2)O (2 center dot 4H(2)O) are reported. The structural investigation of these compounds based on X-ray crystal analysis shows that the copper(I) centers adopt different coordination geometries, O(N)CuP2+ and NCuP2+ for complexes 1 and 2, respectively. Upon irradiation of a degassed organic solution of L at 365 nm, photoinduced isomerization reaction and an intramolecular proton transfer of ligand L were detailed studied by absorption spectral changes. A spectroscopic investigation involving time-dependent density functional theory calculations allows assignment of the excited states that relate to emission and transient absorption spectra. The observed lower-energy absorption bands appearing in the region of 413 and 418 nm for 1 and 2 in dichloromethane are assigned to ligand-to-ligand charge transfer (LLCT, phosphine -> napy) transition in nature. Compared with well-structured solid-state emission originating from pi pi* transition of ligand L, complexes 1 and 2 exhibit intense room-temperature solid-state emissions with lambda(max) at 586 and 620 nm, respectively. The energy and the shape of the emission bands are clearly different from that of the ligand, indicating the emissions come from different excited states. (C) 2011 Elsevier B.V. All rights reserved.

Development of 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridines and their salts as potent cytotoxic agents and topoisomerase I/II alpha inhibitors

A novel series of 35 angularly fused pentacyclic 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridines and 13H-benzo[f]chromeno[4,3-b][1,7]naphthyridin-5-ium chlorides were designed and synthesized. Their cytotoxic activities were investigated against six human cancer cell lines (NCIH23, HCT15, NUGC-3, ACHN, PC-3, and MDA-MB-231). Among all screened compounds; 28, 30, 34, 35, 46, 48, 52, and 53 compounds exhibited potent cytotoxic activities against all tested human cancer cell lines. Further, these potent lead cytotoxic agents were evaluated against human Topoisomerase I and II alpha inhibition. Among them, the compound 48 exhibited dual Topoisomerase I and II alpha inhibition especially at 20 mu M concentrations the compound 48 exhibited 1.25 times more potent Topoisomerase II alpha inhibitory activity (38.3%) than the reference drug etoposide (30.6%). The compound 52 also exhibited excellent (88.4%) topoisomerase I inhibition than the reference drug camptothecin (66.7%) at 100 mu M concentrations. Molecular docking studies of the compounds 48 and 52 with topo I discovered that they both intercalated into the DNA single-strand cleavage site where the compound 48 have van der Waals interactions with residues Arg364, Pro431, and Asn722 whilst the compound 52 have with Arg364, Thr718, and Asn722 residues. Both the compounds 48 and 52 have pi-pi stacking interactions with the stacked DNA bases. The docking studies of the compound 48 with topo IIa explored that it was bound to the topo II alpha DNA cleavage site where etoposide was situated. The benzo[f]chromeno[4,3-b][1,7]naphthyridine ring of the compound 48 was stacked between the DNA bases of the cleavage site with pi-pi stacking interactions and there were no hydrogen bond interactions with topo II alpha.

A simple neutral naphthyridine-based chemosensor 1, which selectively recognizes the tetrabutylammonium salt of N-acetyl-l-proline over the other N-acetyl-l-amino acid salts studied in CHCl3 containing 0.1% DMSO, has been designed and synthesized. Moreover, the complexation-induced change in emission characteristics of 1 distinguishes the amino acid salts examined from their conjugate acids. Interaction studies were performed by UV-vis, fluorescence and NMR spectroscopic methods.

Rearrangement of 7-Aryloxazolo[5,4-b]pyridines to Benzo[c][1,7]naphthyridine-4(3H)-ones and Thieno[3,2-c][1,7]naphthyridine-6(7H)-ones

In this work, we describe the development of the rearrangement for 7-aryl-substituted oxazolo[S,4-b]pyridines treated with aluminum chloride into synthetically hard-to-reach benzo[c][1,7]naphthyridinones. The discovered rearrangement is applied to a variety of electron-rich (hetero)arene substrates. It offers the advantages of mild conditions (90 degrees C temperature), fast reaction rates (<4 h), compatibility with air moisture, and the use of inexpensive commercial reagents. The proposed reaction mechanism and key elementary reaction acts were studied in detail using quantum chemical calculations. The photophysical properties of the synthesized compounds were studied by steady-state UV-vis spectroscopy. 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 126-30-7 help many people in the next few years. Safety of 2,2-Dimethylpropane-1,3-diol.

Probing the single pair rupture force of supramolecular quadruply hydrogen bonding modules by nano-adhesion measurement

Studying quadruply hydrogen bonding (QHB) module interactions in materials matrices presents a significant challenge because a wide variety of non-covalent interactions may be relevant. Here we introduce a method of surface modification with DeUG (7-deazaguanine urea), DAN (2,7-diamido-1,8-naphthyridine) and UPy (2-ureido-4[1H]-pyrimidone) modules to form self-assembled monolayers (SAMs) on a glass surface. The QHB interactions under mechanical stress were investigated by measuring adhesion force using PS-DAN (DAN modified polystyrene), PBMA-DeUG (DeUG modified poly butyl methacrylate) and PBA-UPy (UPy modified poly butyl acrylate) as adhesion promoters. A mechanical lap-shear test was used to evaluate the fracture resistance of QHB heterocomplexes. The maximum load at fail showed that QHB interaction contributed significantly (72%) to overall adhesion. For the QHB modified glass surface, using a polymer modified with its complementary QHB partner greatly facilitated their pairing efficiency, up to 40% for DAN-DeUG. A general method from which single pair ruptures force of QHB modules could be obtained using thermodynamic data obtained from solution chemistry was proposed. Using this method, the single pair rupture force for UPy-UPy was measured as 160 pN, and the single pair rupture force for DAN-DeUG was obtained as 193 pN.

QSAR studies on substituted 3- or 4-phenyl-1,8-naphthyridine derivatives as antimicrobial agents

Quantitative Structure Activity Relationship correlating the antitubercular and antibacterial (Staphylococcus aureus and Escherichia coli) activities with the structural descriptors of reported naphthyridine derivatives was developed. The data were divided into training and test sets. The former was used to develop the regression model and the latter was used to examine the predictive capability of these models. The statistical measures such as squared correlation coefficient (r (2) = 0.79-0.84), adjusted squared correlation coefficient (r (2) (adj) = 0.78-0.83) F-ratio (26.85-67.16), and cross-validation (q (2) = 0.74-0.79) were found to be satisfactory for all activities and the predictions were within the 99% confidence level. The models contained atom type, thermodynamic, structural, and electrotopological descriptors which emphasized the importance of the size, shape, and the lipophilicity of the molecule.
