The synthesis of Poly[1,5-naphthyridine-(3-hexylthiophene)] (1) semi-conducting polymer has been accomplished by adopting both conventional and microwave-assisted Suzuki-Miyaura cross-coupling reaction between 3-hexylthiophene-2,5-diboronic ester and 2,6-dibromo-1,5-naphthyridine. The synthesized copolymer was characterized by modern spectroscopic techniques including percent reflectance (%R), gel permeation chromatography (GPC), cyclic voltammetry (CV), Raman spectroscopy, thermogravimetric analysis (TGA), FTIR and NMR. The morphology of copolymer was examined via FESEM. Optical bandgap was calculated from the absorption edge of %R and found 2.26 eV. The electrochemical and transport properties of 1 were investigated both in the bulk as well as in thin film form. Cyclic voltammetry (CV) results of 1 as a bulk form in H2SO4 solution indicated that the concentration of the polymer in the solution is not well defined because of polymer poor solubility in aqueous solutions. On the other hand, the sulfur group which works as electron donating makes the system more electron-rich. This can be explained by the absence of the reduction peak. For the thin film, two single oxidation peaks were obtained at around 0 V and 0.3 V for both cases. Different solvents can tune the transport properties of the polymer as can be seen from the two CVs where BF3 exhibited enhanced transport properties over ACN. This polymer was also employed in dye-sensitized solar cells as a photosensitizer. The solar cell under AM 1.5 G illumination at 100 mW/cm(2) shows power conversion efficiency of 0.67% with an open circuit voltage of 621 mV, a short circuit current of 2.0 mA/cm(2), and a fill factor of 55%.

We have achieved the synthesis of 1-aryl-2-substituted 4-oxoquinoline and 4-oxo-1,8-naphthyridine derivatives, which cannot be synthesized by known methods, via two useful synthons, 2-formyl-4-oxoquinoline and 2-methylsulfonyl-4-oxo-1,8-naphthyridine. We also succeeded in the synthesis of 1-aryl-3-fluoro-4-oxoquinoline by fluorocyclization of N-arylenaminone with Selectfluor (R) and potassium carbonate in DMF in a one-pot procedure. To the best of our knowledge, this is the first synthesis of 3-fluoro-4-oxoquinoline derivatives. We confirmed that these protocols were mutually applicable to the synthesis of 4-oxoquinoline and 4-oxo-1,8-naphthyridine derivatives.

In this study, ZnO/Ag/Fe3O4/CNTs nanoparticles (NPs) immobilized on carbon nanotubes (ZnO/Ag/Fe3O4/CNTs) were synthesized using Petasites hybridus rhizome water extract as a renewable, mild, and safe reducing agent and effective stabilizer without adding any surfactants. For the confirmation of the structure of the green synthesized NPs, various methods such as X-ray diffraction (XRD), FESEM, transmission electron microscopy (TEM), Energy-Dispersive X-Ray Spectroscopy (EDS), and Vibrating Sample Magnetometer (VSM) were employed. The ZnO/Ag/Fe3O4/CNTs magnetic NPs as a high performance catalyst was employed for the preparation of naphthyridine derivatives in high yields via the multicomponent reactions of phthalaldehyde, 2-aminoactonitrile, activated acetylenic compounds, alpha-haloketones, triphenyphophine, and ammonium acetate in aqueous media at ambient temperature. Due to having isoquinoline core, we investigate antioxidant property of some synthesized compounds by diphenyl-picrylhydrazine (DPPH) radical trapping and power of ferric reduction experiment. Furthermore, the disk diffusion test on Gram-positive and Gram-negative bacteria IS utilized for investigation of antimicrobial activity of some naphthyridines. The achieved outcomes of this experiment demonstrate that these synthesized compounds could prevent from growth of bacteria. Short time of reaction, high yields of product, easy separation of catalyst, and products are some benefits of this process.

Disruption of the hypothalamic-pituitary-adrenal axis is an established finding in patients with anxiety and/or depression. Chronic corticosterone administration in animals has been proposed as a model for the study of these stress-related disorders and the antidepressant action. Alterations of the central noradrenergic system and specifically of inhibitory alpha(2)-adrenoceptors seem to be part of the pathophysiology of depression and contribute to the antidepressant activity. The present study evaluates in male rats the effect of chronic corticosterone treatment during 35 days (16-20 mg kg(-1) day(-1)) on the sensitivity of alpha(2)-adrenoceptors expressed in the somatodendritic and terminal noradrenergic areas locus coeruleus (LC) and prefrontal cortex (PFC), respectively. Further, the effect of chronic fluoxetine treatment (5 mg kg(-1), i.p., since the 15th day) on the sensitivity of alpha(2)-adrenoceptors was examined under control conditions and in corticosterone-treated rats. The alpha(2)-adrenoceptor functionality was analysed in vitro by agonist-mediated [S-35]GTP gamma S binding stimulation and in vivo through the modulation of noradrenaline (NA) release evaluated by dual-probe microdialysis. The concentration-effect curves of the [S-35]GTP gamma S binding stimulation by the agonist UK14304 (5-bromo-N-(4,5-dihydro-1H-imidazol-2-yl)-6-quinoxalinamine) demonstrated a desensitization of cortical alpha(2)-adrenoceptors induced by corticosterone (-logEC(50) = 6.7 +/- 0.2 vs 8.2 +/- 0.3 in controls) that was reverted by fluoxetine treatment (-logEC(50) = 7.5 +/- 0.3). Local administration of the alpha(2)-adrenoceptor antagonist RS79948 ((8aR,12aS,13aS)-5,8,8a,9,10,11,12,12a,13,13a-decahydro-3-methoxy-12-(ethylsulfonyI)-6H-isoquino [2,1 -g] [1,6]naphthyridine) (0.1-100 mu mol L-1) into the LC induced a concentration-dependent NA increase in the PFC of the control group (E-max = 191 +/- 30%) but non-significant effect was observed in corticosterone-treated rats (E-max = 133 +/- 46%), reflecting a desensitization of a 2 -adrenoceptors that control the firing of noradrenergic neurons. Fluoxetine treatment did not alter the corticosterone-induced desensitization in this area (E-max = 136 +/- 19%). No effect of fluoxetine on alpha(2)-adrenoceptor functionality was observed in control animals (E-max = 223 +/- 30%). In PFC, the local administration of RS79948 increased NA in controls (E-max = 226 +/- 27%) without effect in the corticosterone group (E-max = 115 +/- 26%), suggesting a corticosterone-induced desensitization of terminal alpha(2)-adrenoceptors. Fluoxetine administration prevented the desensitization induced by corticosterone in the PFC (E-max = 233 +/- 33%) whereas desensitized alpha(2)-adrenoceptors in control animals (E-max = -24 +/- 10%). These data indicate that chronic corticosterone increases noradrenergic activity by acting at different alpha(2)-adrenoceptor subpopulations. Treatment with the antidepressant fluoxetine seems to counteract these changes by acting mainly on presynaptic alpha(2)-adrenoceptors expressed in terminal areas.

Two stereoisomers of cis-[Ru(bpy)(pynp)(CO)Cl]PF(6) (bpy = 2,2′-bipyridine, pynp 2-(2-pyridyl)-1,8-naphthyridine) were selectively prepared. The pyridyl rings of the pynp ligand in [Ru(bpy)(pynp)(CO) Cl](+) are situated trans and cis, respectively, to the CO ligand. The corresponding CH(3)CN complex ([Ru(bpy)(pynp)(CO) (CH(3)CN)](2+)) was also prepared by replacement reactions of the chlorido ligand in CH(3)CN.

[Ru(bpy)(2)(BNIQ)](2+) (BNIQ= Benzor[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site IDNAKRu] compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)(2)(2+) and [Fe(CN)(6)](3-) implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.
