Erbium anchored iminodiacetic acid (IDA) functionalized CoFe(2)O(4)nano particles: an efficient magnetically isolable nanocomposite for the facile synthesis of 1,8-naphthyridines

A novel functional material was developed by immobilizing an Iminodiacetic acid-erbium (Er) complex onto the surface of magnetic spinel CoFe(2)O(4)nanoparticles. The obtained nanocomposite was fully characterized using different analytical techniques such as FT-IR, XRD, SEM, BET, EDX and X-ray atomic mapping analysis. The catalytic activity of this novel material was investigated in the successful synthesis of 1,8-naphthyridine derivativesviaa three component reaction involving 2-aminopyridine, malononitrile and various aryl aldehydes. The reactions ended up with excellent yields in short reaction times. The catalyst was reused seven times in the proposed reaction without appreciable loss of activity.

Antilipolytic effects of 1,8-naphthyridine derivatives beta-adrenoceptor antagonists in rat white adipocytes

The rat fat cell beta-adrenoceptors were investigated by studying the effects of new 1,8-naphthyridine derivatives synthesized starting from 7-amino-2-chloro-3-phenyl-1,8- naphthyridine on lipolysis induced by isoprenaline, and alprenolol. Lipolysis induced by isoprenaline agonist was competitively antagonized by the 1,8-naphthyridine analogue with a 7-hydroxy-2-(4′-methoxybenzylamine)-6-nitro-3-phenyl substituent designated as 3. In contrast, 10, 50, and 100 mu m of 7-methoxy and 7-ethoxy derivatives did not modify the concentration- response curve of isoprenaline. A rightward shift of the curve was, however, observed with 50 mu m of a 7-methoxy-2-(4 methoxybenzylamine)-6-amino-3-phenyl substituent designated as 10. The selective beta 1-AR antagonist, 7-hydroxy-4-morpholinomethyl-2-piperazino-1,8-naphthyrid ine slightly reduced isoprenaline- induced lipolysis only at high doses. Alprenolol-mediated lipolytic effect was antagonized by derivative 3, 10 and the selective beta 3-AR antagonist SR 59,230A, but resistant to the selective beta 1-AR antagonist 7-hydroxy-4-morpholinomethyl- -2-piperazino-1,8-naphthyridine. The results provide preliminary pharmacological evidence for the antilipolytic effect of the newly synthesized 1,8-naphthyridine derivatives on rat fat cells. The analogues designated as 3 and 10 were the most potent antagonists of this series.

Pharmacokinetic evaluation of C-3 modified 1,8-naphthyridine-3-carboxamide derivatives with potent anticancer activity: lead finding

To develop naphthyridine derivatives as anticancer candidates, pharmacokinetic (PK) evaluations of 10 novel derivatives of 1,4-dihydro-4-oxo-1-proparagyl-1,8-naphthyridine-3-carboxamide, with potent anticancer activity were done using in vitro ADME (absorption, distribution, metabolism, excretion) and pharmacokinetic-pharmcodynamic (PK/PD) assays. Only derivatives 5, 6, 9 and 10 showed better metabolic stability, solubility, permeability, partition coefficient and cytochrome P450 (CYP) inhibition values. PK of derivatives 5, 6, 9 and 10 in rat showed comparable PK profile for derivative 5 (C-0 = 6.98 mu g/mL) and 6 (C-0 = 6.61 mu g/mL) with no detectable plasma levels for derivatives 9 and 10 at 5.0 mg/kg i.v. dose. PK/PD assay of derivatives 5 and 6 in tumor-bearing mice (TBM) showed comparable PK but tumor plasma index (TPI) of derivative 6 (4.02) was better than derivative 5 (2.50), suggesting better tumor uptake of derivative 6. Derivative 6, as lead compound, showed highest tumor growth inhibition (TGI) value of 33.6% in human ovary cancer xenograft model.

Synthesis and biological evaluation of novel fused indolo [3, 2-c] [1,8] naphthyridine derivatives as potential antibacterial agents

Nine novel fused indolo [1,8] naphthyridine derivatives were synthesized using the Povarov reaction, in a one-pot system, and were fully characterized by spectroscopic techniques such as FT-IR, NMR, TOF-MS, and elemental analysis. Furthermore, their antibacterial activities against six bacterial strains were assessed. The results of the bioassay demonstrated that compounds 4a, 4c, and 4i showed good inhibitory effect with a MIC value ranging from 0.04687 to 0.09375 mu M against Bacillus cereus and Staphylococcus aureus. The toxicity of 4a-i, evaluated through mutagenicity test against Salmonella typhimurium TA 98 and TA100 strains, revealed that there was no significant increase in the number of revertant colonies in comparison with the control, sodium azide.

Tool inhibitors and assays to interrogate the biology of the TRAF2 and NCK interacting kinase

The TRAF2 and NCK interacting kinase (TNIK) has been proposed to play a role in cytoskeletal organization and synaptic plasticity and has been linked, among others, to neurological disorders. However, target validation efforts for TNIK have been hampered by the limited kinase selectivity of small molecule probes and possible functional compensation in mouse models. Both issues are at least in part due to its close homology to the kinases MINK1 (or MAP4K6) and MAP4K4 (or HGK). As part of our interest in validating TNIK as a therapeutic target for neurological diseases, we set up a panel of biochemical and cellular assays, which are described herein. We then examined the activity of known amino-pyridine-based TNIK inhibitors (1, 3) and prepared structurally very close analogs that lack the ability to inhibit the target. We also developed a structurally orthogonal, naphthyridine-based TNIK inhibitor (9) and an inactive control molecule of the same chemical series. These validated small-molecule probes will enable dissection of the function of TNIK family in the context of human disease biology.

Application of 1066-54-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 1066-54-2 is helpful to your research.

A 2-Styryl-1,8-naphthyridine derivative as a versatile fluorescent probe for the selective recognition of Hg2+ Ag+ and F- ions by tuning the solvent

A novel fluorescent probe 1 has been synthesized by a microwave reaction, and its ion-binding and fluorescence-sensing properties have been investigated under different solvent conditions. The analysis results indicated that probe 1 can act as a multiple analysis probe by simply tuning the solvent. Probe 1 exhibited high selectively toward Hg2+ through fluorescence quenching in H2O/DMF. In H2O/1,4-dioxane solution, probe 1 selectively recognized and discriminated between Ag+ and Hg2+ displaying ratiometric behaviour. Moreover, probe 1 readily recognized the anion F- via the ratiometric fluorescent mode in CH3CN. Furthermore, distinct colour changes were observed under UV light, which can be seen by the naked eye and thus used for distinguishing Hg2+, Ag+ and F- from the other ions screened herein using probe 1. Interestingly, almost pure white light emission was evident by simply tuning the F- anion-concentration, which makes this system a potential candidate for smart and tunable luminescent materials.

Expanding chemical space of DNA-binding molecules with three base-binding units

A new molecule NC3-3 designed to expand chemical space of parent molecule NCD by adding the third base-binding unit was reported. NC3-3 bound to the G-G mismatch in the 5′-CGG-3’/5′-CGG-3′ motif but not to that in 5′-GGC-3’/5′-GGC-3′. This binding selectivity is similar to that reported for NCD. Fluorimetric screening of NCD and NC3-3 to dsDNA library containing yGw/xGz motifs showed that NC3-3 still kept the sequence selectivity as we observed for NCD-binding. The third naphthyridine heterocycle in NC3-3 affected the mode of the binding, but a little effect on the sequence selectivity.

Cationic complexes of dirhodium(II) with 1,8-naphthyridine: Catalysis of reactions involving silanes

The synthesis of cationic dirhodium(II) complexes by partial or total substitution of the acetate groups of [Rh-2(OAC)(4)] with different homoleptic neutral bidentate ligands has been attempted. The ligand 1,8-naphthyridine gave the best results: substitution of one as well as of all four acetate ligands is possible, giving rise to mono-, di- and tetra-cationic complexes. One of the resulting tetrasubstituted complexes has been structurally characterised and found to exhibit the expected lantern-shaped structure. All cationic complexes have been investigated as catalysts in different reactions involving silanes: promising results have been obtained, particularly in the silylformylation of alkynes.

Iridium complexes with ligands of 1,8-Naphthyridine-2-carboxylic acid derivatives-preparation and catalysis

Complexation of 1,8-naphthyridine(Np)-2-carboxylic derivatives L-1-L-3 [L-1 = Np-2-COOH, L-2 = Np-2-CONH2, L-3 = Np-2-CONHCH2Py] with [Ir(COD)(mu-OMe)](2) yielded the corresponding complexes [Ir(COD)(L-n)] (1 similar to 3, n = 1 similar to 3, respectively). The potential tridentate L-3 behaves as a bidentate donor in the complex 3. Treatment of L-1 with [Ir(COD)Cl](2) under nitrogen atmosphere gave a Ir(III) hydride complex [Ir(COD)(L-1)HCl] (4). However, carrying out the reaction in the presence of oxygen rendered a Ir(III) dichloride species [Ir(COD)(L-1)Cl-2] (5). All these complexes were characterized by spectroscopic analyses and X-ray single crystal determination. Catalytic activity of iridium complexes in amination of amines with alcohols was screened. It appears that iridium amido complexes 2 and 3 show excellent catalytic activity on amination of anilines with alcohols in the presence of Cs2CO3 at 120 degrees C.
