By using tetranaphthyridyl-triamine ligand, N-2-(2-(1,8-naphthyridin-7-ylamino)-1,8-naphthyridin-7-yl)-N-7-(1,8-naphthyridin-2-yl)-1,8-naphthyridine-2,7-diamine (H(3)tentra), double-stranded dinuclear helical compounds [M-2(H(3)tentra)(2)(ClO4)(4)] [M = Ni-II (1), Co-II (2), Fe-II (3), Zn-II (4)] were synthesized and structurally characterized. The single X-ray crystal structure of iron(II) complex showed that both of H(3)tentra ligands wrap around the metal-metal axis giving rise to a double-stranded dinuclear helical compound with Fe-Fe separation of ca. 5.326 angstrom. Each ligand uses two nitrogen atoms from two different napthyridine rings, to coordinate one metal centre (Fe or Fe(A)) and therefore, the geometry about the metal ions was described as distorted tetrahedral, with both ligands acting as bisbidentate N4 donors. This distortion is shown by the angles between nitrogen and iron atoms, which range from 80.45(15) to 143.32(14)degrees. Distorted tetrahedral environment was also proposed for the other complexes on the basis of the magnetic measurements and X-ray results. Strong pi-pi interactions were observed for all synthesized double stranded helicates of H(3)tentra ligand. The measured chi T-M values at 300 K for complexes 2 and 3 found larger than the expected values for two high-spin Co(II) with S = 3/2 and for Fe(II) ions with S = 2 and g = 2, which attributed to the unquenched orbital coupling.

Correlation between naphthyridine-like structures of polyacrylonitrile stabilized fibers and modulus of carbon fibers was investigated. It was found that naphthyridine-like structures, which is a kind of characteristics structure in the polyacrylonitrile stabilized fibers, influence the modulus of carbon fibers. The naphthyriding-like structures can convert to graphite layers, which induce the degree of graphitization and crystallite size to improve, so the more the naphthyriding-like structures form in the polyacrylonitrile stabilized fibers, the higher the modulus of carbon fibers is.

A new methodology has been developed for the synthesis of novel 2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylates from 2-aminonicotinaldehyde, Meldrum’s acid, and the corresponding alcohols in the presence of anhydrous iron(III) chloride as a cheap and readily available catalyst. The structure of the synthesized compounds was established by IR, H-1 NMR, and mass spectral data and elemental analyses. All the synthesized compounds were evaluated for their in vitro antibacterial and antifungal activity, and the activity of some derivatives was comparable with the activity of Ciprofloxacin and Nystatin used as reference drugs.

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 298-96-4, in my other articles. COA of Formula: https://www.ambeed.com/products/298-96-4.html.

We have previously synthesized a series of 1,8-naphthyridine-3-carboxamide derivatives to identify potential anti-cancer/anti-inflammatory compounds. Three derivatives, 7-chloro-N-(3-(cyclopentylamino)-3-oxo-1-phenylpropyl)-6-fluoro-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-22), 7-chloro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-31) and 7-chloro-6-fluoro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-34) demonstrated high cytotoxicity against a number of cancer cell lines and inhibited secretion of IL-1-beta and IL-6. In the present study, C-22, C-31 and C-34 were assessed for modulation of pro-inflammatory cytokines, TNF-alpha and IL-8, chemokine RANTES and NO produced by lipopolysaccharide (LPS)-treated mouse Dendritic cells (DCs). Among the 3 compounds, C-34 showed the most potent inhibition of inflammatory markers in DC model at 02 and 2 mu M. C-34 also significantly downregulated the secretion of TNF-alpha, IL-1-beta and IL-6 by murine splenocytes and THP-1 cells against IFS induced levels. In vitro effects of C-34 on bone marrow toxicity were assessed in CFU-GM assay. Human CPU-GM population was comparatively more sensitive to C-34 (0.1-10 mu M) than murine CPU-GM. IC50 values for murine and human CPU-GM were not attained. C-34 was further examined for in vivo suppression of LPS induced cytokines in a mice model. At doses ranging from 125 to 5 mg/kg, C-34 led to significant inhibition of TNF-alpha, IL-1-beta and MIP-1-alpha. At the highest dose of 5 mg/kg, C-34 also protected LPS-treated mice against endotoxin-induced lethality. In conclusion, C-34 demonstrates anti-inflammatory activity in vitro and in vivo in addition to cytotoxic properties. This finding suggests its potential for further development as a synthetic naphthyridine derivative with dual anti-cancer and anti-inflammatory (cytokine inhibition) properties.

Naphthyridine-based fluorescent probe H1 was synthesized and characterized for the quantification and selective detection of Uric Acid (UA) in live cell. In presence of UA, H1 forms the specific host-guest complex mainly through intermolecular hydrogen bonding and aromatic stacking which produces turn-off fluorescence. The probe and UA is found to be 1:1 stoichiometry on the basis of absorption and fluorescence titrations. The probe H1 has been shown to detect UA up to 0.6 mu M at pH 7.4. DFT-TDDFT calculations were performed in order to demonstrate the sensing mechanism and the electronic properties of the receptor-donor complex. The selectivity was evaluated in Vero cells in the presence of UA with other purine derivatives, structurally similar to UA. It was found to exhibit no cytotoxicity effect in tested concentration of H1 and good membrane permeability for the detection of UA in living cell system. The unknown concentration of UA in serum and urine can be measured easily using the fluorescence property of probe H1. (C) 2017 Elsevier Inc. All rights reserved.
