A simple route for preparation of 4-substituted thieno/furo[2,3-c]quinoline compounds is reported in this paper. These compounds were synthesized by using Suzuki coupling between appropriate boronic acid and 2-iodoaniline, followed by reaction with diverse aldehydes in the presence of a catalytic amount of FeCl3. Naphthyridine analogues were also prepared in order to demonstrate the efficacy of the developed method. Further anti-tubercular activity screening of the molecules was undertaken, wherein compounds bearing a fused furo[2,3-c][1,8]naphthyridine skeleton displayed highest activity. The best MIC (minimum inhibitory concentration) value of 5.6 mu mol was obtained for 4-(4-methoxyphenyl)furo[2,3-c][1,8]naphthyridine, which is found to be superior to the existing first line anti-tubercular drug ethambutol (7.6 mu mol).

New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, SMILES is C1=C([N+]([O-])=O)C(=CC=C1C(=O)O)N, belongs to naphthyridine compound. In a document, author is Boskovic, Miladin, introduce the new discover, Application In Synthesis of 4-Amino-3-nitrobenzoic acid.

Five new dinuclear palladium(II) complexes with general formula, [{Pt(L)Cl}(2)(mu-1,5-nphe)](NO3)(2)(L is ethylenediamine (en), (+/-)-1,2-propylenediamine (1,2-pn),trans-(+/-)-1,2-diaminocyclohexane (dach), 1,3-propylenediamine (1,3-pd), (+/-)-1,3-pentanediamine (1,3-pnd) and 1,5-nphe is bridging 1,5-naphthyridine ligand) were synthesised and spectroscopically characterized.In vitrocytotoxic activity of these complexes was evaluated against mouse mammary carcinoma (4T1), colon (CT26), lung cancer cells (LLC1) and melanoma (B16-F10) as well as human lung adenocarcinoma (A549), mammary carcinoma (MDA-MB-468), and colon cancer (HCT 116). The investigated complexes reduced viability of tumor cells in dose dependent manner. Dinuclear Pd(II) complexes act less cytotoxic toward tumor cells, compare to cisplatin, but also have greater selectivity toward mesenchymal stem cells. The potential mechanism of cell death of tumor cells treated with palladium(II) 1,5-naphthyridine dinuclear complexes is enhanced apoptosis, facilitated by down-regulation of anti-apoptotic Bcl-2 and up-regulation of pro-apoptotic Caspase-3.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

In a document, author is Park, T, introduce the new discover.

An exceptionally strong quadruply hydrogen-bonded complex is formed between 2,7-diamido-1,8-naphthyridine 3 (DAN) and the butylurea of guanosine 6 (UG) in chloroform. The UG unit can be prepared in four steps from guanosine on a 10 g scale in excellent yields without chromatographic purification. The association constant (K-assoc approximate to 5 x 10(7) m(-1)) for the UG(.)DAN complex determined by fluorescence energy transfer from the naphthyridine unit of 3 to coumarin 343 covalently linked UG (18) is among the highest reported for a neutral DNA base-pair analogue. The weak self-association of DAN (K-dimer < 10 m(-1)) and UG (K-dimer ca. 200-300 m(-1)) means that the UG-DAN complex forms with unparalleled fidelity. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

The biologically significant 12,13-dihydro-6H-benzo[h]chromeno[3,4-b][1,6]naphthyridin-6-ones and 6,10-dihydro-5H-benzo[h]pyrazolo[3,4-b][1,6]naphthyridines were synthesized starting from 2-(N-propargylamino)-arylaldehydes and 3-aminocoumarins or 3-methyl-1-aryl-1H-pyrazol-5-amines in the presence of an Amberlyst-15 catalyst in PEG-200 in good yields. The easy access to diverse complex molecules in a single operation from readily available starting materials, a commercially available, transition metal-free and recyclable catalyst, the use of a green solvent, a very high atom economy and the release of water as the only side product are the highlights of this protocol.

In a patnet, author is Matsui, Jun, once mentioned the new application about 1185-55-3.

A strategy for arranging two porphyrin moieties in a face-to-face fashion in polymeric material was demonstrated by molecular imprinting, whereby porphyrin Zn(II) complex monomers were cross-linked with ethylene glycol dimethacrylate in the presence of pyrazine or 1,5-naphthyridine as a template molecule. In chromatographic studies using the resultant imprinted polymers as stationary phase, both the polymers showed selectivity for the original template molecule, suggesting that two zinc porphyrin moieties were immobilized in the face-to-face fashion, and were center-aligned for pyrazine recognition and offset-arranged for 1,5-naphthyridine recognition. The imprinted polymer with porphyrin moieties also showed a decrease in its fluorescence intensity in response to the concentration of the target molecule, suggesting the potential utility as sensing material.

Electrocatalytic water oxidation using the oxidatively robust 2,7-[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine ligand (BPMAN)-based dinuclear copper(II) complex, [Cu-2(BPMAN)(-OH)](3+), has been investigated. This catalyst exhibits high reactivity and stability towards water oxidation in neutral aqueous solutions. DFT calculations suggest that the OO bond formation takes place by an intramolecular direct coupling mechanism rather than by a nucleophilic attack of water on the high-oxidation-state (CuO)-O-IV moiety.

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)(2)](PF6)(2) ( [1] (PF6)(2); L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2′-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1](PF6)(2) was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)(CH3CN)(bpy)(2)](PF6)(2) ([2] (PF6)(2)), was formed. X-ray crystallographic data revealed that, in [2](PF6)(2), L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)(2) shows a unique haptotropic rearrangement in an acetonitrile solution.
