Electrical conductivity studies on polycrystalline samples show that structural differences in the polymers lead to different conductivity values. These results highlight the flexible coordination chemistry of d(10) silver(I) centers, as well as the challenges of ligand design when targeting well-defined multinuclear silver complexes.

The effect of a peripheral disulfide bridge substituent on the phenolic O-H bond dissociation energy (BDE) and the ionization potential (IP) of naphthyridine diol has been studied by density functional theory (DFT) calculation. Compared with naphthalene diol, the substituent of a peripheral disulfide bridge group is very efficient in reducing the BDE, whereas the insertion of nitrogen atoms into the naphthalenic ring only slightly changes the BDE of O-H bond but dramatically enhances the IP. It is similar with the stereoelectronic effect of the heterocyclic ring for the well-known alpha-tocopherol antioxidant and leads to a highly delocalized spin distribution. With the incorporation of these two aspects, a potential antioxidant is expected to be more active and more stable than alpha-tocopherol.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1066-54-2, in my other articles. Recommanded Product: Ethynyltrimethylsilane.

A new 1,8-naphthyridine based di-olefinic chemosensor was designed, synthesized and its sensing behavior towards metal ions was investigated by UV-vis, fluorescence and H-1 NMR spectroscopic methods. A highly Hg2+-selective fluorescence enhancing property (>1.5-fold) in conjunction with a visible colorimetric change from yellow to purple has been observed, leading to a potential fabrication of both naked-eye and fluorescence detection of Hg2+. Our designed sensor of the donor-acceptor-donor system shows high selectivity towards mercury(II) ion over other competing metal ions. (C) 2011 Elsevier B.V. All rights reserved.

During drug discovery efforts targeting inhibition of cytochrome P450 11B2 (CYP11B2)-mediated production of aldosterone as a therapeutic approach for the treatment of chronic kidney disease and hypertension, (S)-6-(5-fluoro-4-(1-hydroxyethyl)pyridin-3-yl)3,4-dihydro-1,8-naphthyridine-1(2H)-carboxamide (1) was identified as a potent and selective inhibitor of CYP11B2. Preclinical studies characterized 1 as low clearance in both in vitro test systems and in vivo in preclinical species. Despite low metabolic conversion, an active ketone metabolite (2) was identified from in vitro metabolite-identification studies. Due to the inhibitory activity of 2 against CYP11B2 as well as the potential for it to undergo reductive metabolism back to 1, the formation and elimination of 2 were characterized and are the focus of this manuscript. A series of in vitro investigations determined that 1 was slowly oxidized to 2 by cytochrome P450s 2D6, 3A4, and 3A5, followed by stereoselective reduction back to 1 and not its enantiomer (3). Importantly, reduction of 2 was mediated by an NADPH-dependent cytosolic enzyme. Studies with human cytosolic fractions from multiple tissues, selective inhibitors, and recombinantly expressed enzymes indicated that carbonyl reductase 1 (CBR1) is responsible for this transformation in humans. Carbonyl reduction is emerging as an important pathway for endogenous and xenobiotic metabolism. With a lack of selective substrates and inhibitors to enable characterization of the involvement of CBR1, 2 could be a useful probe to assess CBR1 activity in vitro in both subcellular fractions and in cell-based systems.

The complexes of 2,7-bis(diphenylphosphorylamino)-1,8-naphthyridine (L) with lanthanide nitrates Ln(NO3)(3) (Ln = Nd, Lu) were investigated to elucidate the coordination ability of a novel type of potentially tetradentate ligands – bis(phosphorylamino) substituted naphthyridines. Mononuclear complexes of 1:1 and 1:2 composition, namely, [Nd(L)(NO3)(3)] (1a), [Nd(L)(NO3)(3)]center dot H2O (1b), [Lu(L)(NO3)(2)(H2O)](NO3) (2), [Nd(L)(2)(NO3)(2)(H2O)](NO3) (3), [Lu(L)(2)(NO3)(H2O)](NO3)(2)center dot 0.75CH(3)CN center dot H2O (4a) and [Lu(L)(2)(NO3) (H2O)](NO3)(2) (4b) were synthesized and studied by IR, Raman, and P-31 NMR spectroscopy in solid state and in solution. Structures of the complexes 1b and 4a were determined by X-ray diffraction. According to X-ray crystallography, vibrational spectroscopy and C, H, N, P elemental analysis data in solid 1:1 complexes one neutral molecule of L serves most likely as O,O,N,N-tetradentate ligand while in the 1:2 complexes only one ligand molecule coordinates in the same O,O,N,N-tetradentate fashion, and the second one serves as O-monodentate one. In solution the coordination mode of the ligand is preserved in all complexes. (C) 2011 Elsevier B. V. All rights reserved.

For a long time, the cobalt(II) complex ([Co(napy)(4)](ClO4)(2)) (napy=1, 8-naphthyridine) has been considered as an eight-coordinate complex without any structural proof. After careful considerations, two complexes [Co(napy)(2)Cl-2] (1) and [Co(napy)(4)](ClO4)(2) (2) based on the bidentate ligand napy were synthesized and structurally characterized. X-ray single-crystal structural determination showed that the cobalt(II) center in [Co(napy)(2)Cl-2] (1) is four-coordinate with a tetrahedral geometry (T-d), while [Co(napy)(4)](ClO4)(2) (2) is seven-coordinate rather than eight-coordinate with a capped trigonal prism geometry (C-2v). Direct-current (dc) magnetic data revealed that complexes 1 and 2 possess positive zero-field splitting (ZFS) parameters of 11.08 and 25.30 cm(-1), respectively, with easy-plane magnetic anisotropy. Alternating current(ac) susceptibility measurements revealed that both complexes showed slow magnetic relaxation behaviour. Theoretical calculations demonstrated that the presence of easy-plane magnetic anisotropy (D>0) for complexes 1 and 2 is in agreement with the experimental data. Furthermore, these results pave the way to obtain four-coordinate and seven-coordinate cobalt(II) single-ion magnets (SIMs) by using a bidentate ligand.
