Silver(I) coordination polymers from dinucleating naphthyridine ligands

Two novel crystalline silver(I) coordination polymers have been synthesized and structurally characterized, using naphthyridine-based ligands that are typically expected to produce dinuclear metal complexes. Electrical conductivity studies on polycrystalline samples show that structural differences in the polymers lead to different conductivity values. These results highlight the flexible coordination chemistry of d(10) silver(I) centers, as well as the challenges of ligand design when targeting well-defined multinuclear silver complexes.

Biotransformation of Finerenone, a Novel Nonsteroidal Mineralocorticoid Receptor Antagonist, in Dogs, Rats, and Humans, In Vivo and In Vitro

Mass balance and biotransformation of finerenone, a nonsteroidal mineralocorticoid receptor antagonist, were investigated in four healthy male volunteers following a single oral administration of 10 mg (78 mu Ci) of [C-14]finerenone and compared with data from studies in dogs and rats. The total recovery of the administered radioactivity was 101% in humans, 94.7% in dogs, and 95.2% in rats. In humans, radioactivity was mainly excreted renally (80%); in rats, it was primarily the biliary/fecal route (76%); and in dogs, excretion was more balanced. Finerenone was extensively metabolized in all species by oxidative biotransformation, with minor amounts of unchanged drug in excreta (humans: 1%; dogs, rats: <9%). In vitro studies suggested cytochrome P450 3A4 was the predominant enzyme involved in finerenone metabolism in humans. Primary metabolic transformation involved aromatization of the dihydronaphthyridine moiety of metabolite M1 as a major clearance pathway with a second oxidative pathway leading to M4. These were both prone to further oxidative biotransformation reactions. Naphthyridine metabolites (M1-M3) were the dominant metabolites identified in human plasma, with no on-target pharmacological activity. In dog plasma, finerenone and metabolite M2 constituted the major components; finerenone accounted almost exclusively for drug-related material in rat plasma. For metabolites M1-M3, axial chirality was observed, represented by two atropisomers (e.g., M1a and M1b). Analysis of plasma and excreta showed one atropisomer (a-series, >79%) of each metabolite predominated in all three species. In summary, the present study demonstrates that finerenone is cleared by oxidative biotransformation, mainly via naphthyridine derivatives.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 39156-41-7 is helpful to your research. Recommanded Product: 39156-41-7.

Design, synthesis, and evaluation of fluorine and Naphthyridine-Based half-sandwich organoiridium/ruthenium complexes with bioimaging and anticancer activity

A range of fluorine and naphthyridine based half-sandwich iridium (III) and ruthenium (II) complexes were synthesized. The iridium complexes possessed excellent antiproliferative properties, a substantial improvement over cisplatin, especially the best 1C containing the fluorine atom and 2C containing the naphthyridine. On the contrary, the ruthenium complexes displayed much less antiproliferative activity. Two X-ray crystal structures were determined. The cytotoxicity of the complexes can be changed flexible by regulating the metal center and the ancillary ligands. The best complex 1C was chose to study further on the mechanism of action. The chemical reactivity such as hydrolysis, reaction with nucleobases, glutathione and catalytic conversion of NADH to NAD(+), were investigated. Complex 1C can react with 9-ethylguanine (9-EtG) and catalyze oxidation of NADH. In addition, the self-luminescence of the complex 1C was also successfully used in confocal microscopy images for elucidating the subcellular localization. Complex 1C specifically targeted to lysosomes in A549 cancer cells and caused lysosomal damages and promote cathepsin B released. Flow cytometry studies confirmed that the biological effects of this type of complexes induced apoptosis, especially late apoptosis. Our results suggested that changes in the mitochondria membrane potential were responsible for apoptosis. The chemistry and biological studies has showed that this class of metal complexes are worthy of further exploration for the design of novel anticancer drugs. (C) 2018 Elsevier Masson SAS.

A new fluorescent enhancement chemosensor for Al3+ and Fe3+ based on naphthyridine and benzothiazole groups

A novel and easily synthesized compound, N-(2-(2-benzothiazol-2-yl)vinyl-4-methyl-1,8-naphthyrine-7-yl)acetamide (1) based on naphthyridine and benzothiazole group, has been developed as a turn-on fluorescent chemosensor for Al3+ and Fe3+ simultaneously. The absorbance and fluorescent intensities of 1 increased linearly in aqueous solution upon the interaction of 1 with Al3+ or Fe3+. The other co-existing metal ions have no obvious effect on the detection. The Job’s plot and the ESI mass spectra indicated the formation of 1:1 complex between 1 and Al3+ or Fe3+. The sensing mechanism was proposed according to the Job’s plot, ESI mass spectra, H-1 NMR spectra, and density functional theory (DFT) calculation. The properties of the model compound N-(2-((2-methylbenzothiazol-6-ylimino)methyl)-4-methyl-1,8-naphthyridin-7-yflacetamide (2), which was designed and synthesized in order to prove the sensing mechanism, also verified the proposed sensing mechanism.

Luminescence-based colorimetric discrimination of single-nucleotide transversions by the combined use of the derivatives of DOTA-conjugated naphthyridine and its terbium complex

We newly synthesized a nucleobase-binding ligand, ND-DOTA, in which 2-amino-5,7-dimethyl-1,8-naphthyridine (ND) was conjugated with 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid (DOTA) via an amide linker, and found that its terbium(III) complex (ND-DOTA-Tb) showed green emission based on an energy transfer from the naphthyridine moiety to Tb3+. The blue emission of ND-DOTA was selectively quenched by adding abasic site-containing DNA duplexes that have pyrimidine bases opposite to the abasic site. In contrast, at the same excitation wavelength, ND-DOTA-Tb showed green emission independently of the bases opposite to the abasic site. Thus, a mixed solution of ND-DOTA and ND-DOTA-Tb enabled the luminescence-based colorimetric discrimination of single-nucleotide transversions with the naked eye at a single excitation wavelength.

Design and synthesis of novel substituted naphthyridines as potential c-Met kinase inhibitors based on MK-2461

Two series of novel 1,5-naphthyridine and 1,6-naphthyridine derivatives were designed and synthesized based on the c-Met kinase inhibitor MK-2461 under the guidance of scaffold hopping strategy. All were tested on c-Met kinase and in vitro anti-tumor activities against Hela and A549 cell lines. The results indicated that 1,6-naphthyridine was a more promising c-Met inhibitory structure core compared with 1,5-naphthyridine. Among them, 26b and 26c showed the best enzymic and cytotoxic activities. The western blot experiments implied that the cytotoxic activity of 26c might be partially through suppressing the phosphorylation of c-Met kinase. (C) 2015 Elsevier Ltd. All rights reserved.
