Selective fluorescence sensing and quantification of uric acid by naphthyridine-based receptor in biological sample

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.

Anion Pairs Template a Trigonal Prism with Disilver Vertices

Here we describe the formation of a trigonal prismatic cage, utilizing 2-formyl-1,8-naphthyridine subcomponents to bind pairs of silver(I) ions in close proximity. This cage is the first example of a new class of subcomponent self-assembled polyhedral structures having bimetallic vertices, as opposed to the single metal centers that typically serve as structural elements within such cages. Our new cage self-assembles around a pair of anionic templates, which are shown by crystallographic and solution-phase data to bind within the central cavity of the structure. Many different anions serve as competent templates and guests. Elongated dianions, such as the strong oxidizing agent peroxysulfate, also serve to template and bind within the cavity of the prism. The principle of using subcomponents that have more than one spatially close, but nonchelating, binding site may thus allow access to other higher-order structures with multimetallic vertices.

Reactivity in 7-benzyl-2,7-naphthyridine Derivatives: Nucleophilic Substitutions, Rearrangements, Heterocyclizations and Related Reactions

Background and Objective: Continuing our studies in the field of a new rearrangement in the 2,7-naphthyridine series, the synthesis and rearrangement of mono-2 and di-amino derivatives 3 of 2,7-naphthyridine was carried out. Taking into account the wide range of pharmacological activities of pyrazole derivatives the synthesis of some 3-amino-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridines 8 and of pyrazolo[3,4-c]-2,7-naphthyridine 12 was described. Methods: Compounds 2 were reacted with amines furnishing the relevant rearrangement products 4. Starting from the 7-benzyl-3-chloro-1-hydrazino-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 6 and 5-hydrazino-6,7,8,9- tetrahydro-3H-pyrazolo[3,4-c]-2,7-naphthyridin-1-amine 12 the 7-benzyl-3-chloro-1-(3,5-dimethyl-1H-pyrazol- 1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 7 and 3,5-dimethyl-1H-pyrazol-1-yl-9,11-dimethylpyrimido[1′, 2′: 1,5] pyrazolo[3,4-c]-2,7-naphthyridine 13 were synthesized, via the Knorr synthesis of pyrazoles. Results: The syntheses of 2-benzyl-6,8-diamino-3,4-dihydro-2,7-naphthyridin-1(2H) ones 4 deriving from the rearrangement of compounds 2 and/or 3 were performed. By reaction with benzylamine compound 2a or 3g gave the unexpected formation of N, 7-dibenzyl-8-(benzylimino)-3-pyrrolidin-1-yl-5,6,7,8-tetrahydro-2,7-naphthyridin- 1-amine 5: in fact, the rearrangement was followed by condensation between the C-1 carbonyl group of the 2,7-naphthyridine ring and the benzylamine. Starting from the 7-benzyl-3-chloro-1-(3,5-dimethyl-1H- pyrazol-1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 7 the relevant 3-amino-7-benzyl-1-(3,5-dimethyl- 1H-pyrazol-1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitriles 8 were obtained. In harsh experimental conditions the nucleophilic substitution of the 1-pyrazolyl residue took place with formation of 7-benzyl- 1,3-bis[(2-hydroxypropyl) amino]-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 10. Moreover, compound 7 reacted with hydrazine hydrate giving the pyrazolo[3,4-c]-2,7-naphthyridine 12, which, in turn, furnished a new tetra-heterocyclic system: 3-benzyl-5-(3,5-dimethyl-1H-pyrazol-1-yl)-9,11-dimethyl-1,2,3,4-tetrahydropyrimido[1′, 2′: 1,5] pyrazolo[3,4-c]-2,7-naphthyridine 13. Conclusion: Replacement of methyl group on piperidine ring of 2,7-naphthyridine system with the benzyl one led to new results. Reaction of compound 2a or 3g with benzylamine brought to an unexpected formation of N, 7-dibenzyl-8-(benzylimino)-3-pyrrolidin-1-yl-5,6,7,8-tetrahydro-2,7-naphthyridin-1-amine 5. The reactivity of 7-benzyl-3-chloro-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridine 7 with nucleophiles was investigated, observing the unexpected substitution of the 1-pyrazolyl residue.

Two Annulated Azaheterocyclic Cores Readily Available from a Single Tetrahydroisoquinolonic Castagnoli-Cushman Precursor

A novel approach to indolo[3,2-c]isoquinoline and dibenzo[c,h][1,6]naphthyridine tetracyclic systems was discovered based on switchable reduction of 2-methoxy-3-(2-nitrophenyl)-1-oxo-1,2,3,4-tetrahydroisoquinoline-4-carboxylic acid prepared via Castagnoli-Cushman reaction. Reduction with ammonium formate resulted in the expected selective transformation of the nitro group (thus providing access to substituted dibenzo[c,h][1,6]naphthyridine via cyclization and dehydrogenation). However, attempted reduction with sodium sulfide initiated a previously unknown reaction cascade including double reduction, cyclization, and decarboxylation, leading to formation of indolo[3,2-c]isoquinoline polyheterocycle in one synthetic step.

Novel 1,5-naphthyridine-chromophores with D-A-D architecture: Synthesis, synthesis, luminescence and electrochemical properties

A series of symmetrical 1,5-naphthyridine compounds with donor-acceptor-donor (D-A-D) architecture and different chromophores were synthesized and characterized. Their thermal, optical and electrochemical properties were investigated systematically. These compounds show robust thermal property with high phase transition temperatures (above 247 degrees C). In addition, all these compounds exhibit intense absorption bands in UV and visible region, which arise from the intramolecular charge transfer (ICT) transition between the donor and acceptor segments. The electron-donating chmmophores on the central naphthyridine cause significant bathochromic shifts of the low energy ICT absorption bands. Meanwhile, all compounds are emissive in solution at room temperature (lambda(em) = 450-520 nm). When the electron-donating ability of the attached chromophores increases, the fluorescent quantum yields of these compounds increase. The calculated ground-state geometries further demonstrate the ICT transition for these molecules from HOMO to LUMO. Their luminescent and electrochemical properties could be used for understanding the structure-property relationship of naphthyridine compounds and developing optical functional materials.

One-pot solvent free synthesis and DNA binding studies of thieno[2,3-b]-1,8-naphthyridines

With the aim of evaluating interaction between double-stranded calf thymus (ds)DNA and sulphur containing fused planar rings, the derivatives of 1,8-naphthyridine containing thiono groups were synthesized by the condensation of 2-mercapto-3-formyl[1,8]naphthyridines using 1-chloroacetone, 2-chloroacetamide, chloroaceticacid, and 2-chloro-1-phenylethanone in the presence of anhydrous potassium carbonate as s catalyst under solvent free microwave irradiation. The structures of the compounds were elucidated on the basis of elemental analysis, IR, H-1 NMR, and mass spectra. The interaction of thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (TNC) (3a) with ct-DNA was studied by UV-Vis spectrophotometry, viscosity, thermal denaturation, as well as cyclic voltammetry experiments. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometric measurements indicated a binding constant of K-b = 2.1 x 10(6) M-1. The thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (3a) increases the viscosity of sonicated rod-like DNA fragments. The binding of TNC to DNA increased the melting temperature by about 4 degrees C. The decrease in peak current heights and shifts of peak potential values are observed by the addition of calf thymus DNA in cyclic voltammetry studies.
