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.

Synthesis and characterization of functionalized polythiophene for polymer-sensitized solar cell

The synthesis of Poly[1,5-naphthyridine-(3-hexylthiophene)] (1) semi-conducting polymer has been accomplished by adopting both conventional and microwave-assisted Suzuki-Miyaura cross-coupling reaction between 3-hexylthiophene-2,5-diboronic ester and 2,6-dibromo-1,5-naphthyridine. The synthesized copolymer was characterized by modern spectroscopic techniques including percent reflectance (%R), gel permeation chromatography (GPC), cyclic voltammetry (CV), Raman spectroscopy, thermogravimetric analysis (TGA), FTIR and NMR. The morphology of copolymer was examined via FESEM. Optical bandgap was calculated from the absorption edge of %R and found 2.26 eV. The electrochemical and transport properties of 1 were investigated both in the bulk as well as in thin film form. Cyclic voltammetry (CV) results of 1 as a bulk form in H2SO4 solution indicated that the concentration of the polymer in the solution is not well defined because of polymer poor solubility in aqueous solutions. On the other hand, the sulfur group which works as electron donating makes the system more electron-rich. This can be explained by the absence of the reduction peak. For the thin film, two single oxidation peaks were obtained at around 0 V and 0.3 V for both cases. Different solvents can tune the transport properties of the polymer as can be seen from the two CVs where BF3 exhibited enhanced transport properties over ACN. This polymer was also employed in dye-sensitized solar cells as a photosensitizer. The solar cell under AM 1.5 G illumination at 100 mW/cm(2) shows power conversion efficiency of 0.67% with an open circuit voltage of 621 mV, a short circuit current of 2.0 mA/cm(2), and a fill factor of 55%.
