A series of naphthyridinone derivatives based on 1a (a precursor of Voreloxin) were designed and synthesized. Seven compounds having >70% inhibition against HL60 at 30 mu mol/L were further evaluated for their in vitro antitumor activity by SRB assay. Results reveal that thiazol-2-y1 and 3-aminomethyl-4-benzyloxyimino-3-methylpyrrolidin-1-yl groups are optimal at the N-1 and C-7 positions of naphthyridinone core, respectively. 10j exhibits broad-spectrum activity (IC50: <0.5-6.25 mu mol/L) against all of the tested cell lines including Etoposide- and/or 1a-resistant ones, and is 1.3-fold to >100-fold more potent than the two references against eight Of these cell lines.

When developing chemical systems it’s of course important to gain a deep understanding of the chemical reaction process. In an article, author is Margiotta, Nicola, once mentioned the application of 179324-87-9, Name is (R)-BoroLeu-(+)-Pinanediol trifluoroacetate, molecular formula is C17H29BF3NO4. Now introduce a scientific discovery about this category, Safety of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate.

In this paper we investigate the possibility of further increase the role of the N-donor aromatic base in antitumor Hollis-type compounds by conferring the possibility to act as a hydrogen-bond donor/acceptor. Therefore, we synthesized the PtII complex cis-[PtCl(NH3)2(naph)]NO3 (1) containing the 1,8-naphthyridine (naph) ligand. The naphthyridine ligand is generally monodentate, and the second nitrogen atom can act as H-bond donor/acceptor depending upon its protonation state. The possibility of forming such an H-bond could be crucial in the interaction of the drug with DNA or proteins. Apart from the synthesis of the compound, in this study we evaluated its in vitro antitumor activity in a wide panel of tumor cell lines, also including cells selected for their sensitivity/resistance to oxaliplatin, which was compared with that of previously reported complex 2 ([PtI(2,9-dimethyl-1,10-phenanthroline)(1-methyl-cytosine)]I) and oxaliplatin and cisplatin as reference compounds. The cytotoxicity data were correlated with the cellular uptake and the DNA platination levels. Finally, the reactivity of 1 towards guanosine 5-monophosphate (5′-GMP) and glutathione was investigated to provide insights into its mechanism of action.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 179324-87-9 is helpful to your research. Safety of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 5089-22-5, Name is 1,4-Bis(benzo[d]oxazol-2-yl)naphthalene, SMILES is C1(C2=NC3=CC=CC=C3O2)=C4C=CC=CC4=C(C5=NC6=CC=CC=C6O5)C=C1, belongs to naphthyridine compound. In a document, author is Gencer, Hulya Karaca, introduce the new discover, Product Details of 5089-22-5.

Owing to the growing need for novel antibacterial agents, we synthesized a novel series of fluoroquinolones including 7-substituted-1-(2,4-difluoropheny1)-6-fluoro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid derivatives, which were tested against clinically relevant Gram positive and Gram negative bacteria. Chemical structures of the synthesized compounds were identified using spectroscopic methods. In vitro antimicrobial effects of the compounds were determined via microdilution assay. Microbiological examination revealed that compounds 13 and 14 possess a good antibacterial profile. Compound 14 was the most active and showed an antibacterial profile comparable to that of the reference drugs trovafloxacin, moxifloxacin, and ciprofloxacin. A significant MIC90 value (1.95 mu g/mL) against S. aureus ATCC 25923, E. coli ATCC 35218, and E. coli ATCC 25922 was recorded for compound 14. We observed reduced metabolic activity associated with compounds 13 and 14 in the relevant bacteria via a luminescence ATP assay. Results of this assay supported the antibacterial potency of compounds 13 and 14. An E. coli DNA gyrase inhibitory assay indicated that compound 14 is a potent inhibitor of E. coli DNA gyrase. Docking studies revealed that there is a strong interaction between compound 14 and the E. coli DNA gyrase enzyme. Genotoxicity and cytotoxicity evaluations of compounds 13 and 14 showed that compound 14 is non-genotoxic and less cytotoxic compared to the reference drugs (trovafloxacin, moxifloxacin, and ciprofloxacin), which increases its biological importance.

Lophocladines A (1) and B (2), two 2,7-naphthyridine alkaloids, were isolated from the marine red alga Lophocladia sp. collected in the Fijian Islands. Their structures were deduced on the basis of high-resolution mass spectra and one- and two-dimensional NMR spectroscopy. Lophocladine A (1) displayed affinity for NMDA receptors and was found to be a delta-opioid receptor antagonist, whereas lophocladine B (2) exhibited cytotoxicity to NCI-H460 human lung tumor and MDA-MB-435 breast cancer cell lines. Immunofluorescence studies indicated that the cytotoxicity of lophocladine B (2) was correlated with microtubule inhibition. This is the first reported occurrence of alkaloids based on a 2,7-naphthyridine skeleton from red algae.

In a patnet, author is Andrews, Michael, once mentioned the new application about 23814-12-2.

2,7-Dimethyl-1,8-naphthyridine (L-1) reacts with pentacarbonylchlororhenium in toluene or chloroform to give the target complex fac-{ReCl(CO)(3)(L-1)}. X-ray crystallographic data were obtained for fac-{ReCl(CO)(3)(L-1)}. The structural and H-1 NMR data suggest that the ligand coordinates to the rhenium in a bidentate fashion in both solid and solution states. The complex was also found to be luminescent in both solution and solid states. The fluxionality of the ligand in solution causes ligand-centred emission to be observed in solution, whereas only (MLCT)-M-3 emission was observed in the solid state. Although the complex was air-stable, the lability of L-1 was studied in H-1 NMR experiments where CD3OD induced complete ligand dissociation over the course of 24 h, and also in reaction of fac-{ReCl(CO)(3)(L-1)} with one equivalent of 2,2′-bipyridine in chloroform which resulted in quantitative ligand exchange.
