In the quest for discovering potent antimicrobial agents with lower toxicity, we envisioned the design and synthesis of nalidixic acid-D-(+)-glucosamine conjugates. The novel compounds were synthesized and evaluated for their in vitro antimicrobial activity against Gram positive bacteria, Gram negative bacteria and fungi. Cytotoxicity using MTT assay over L6 skeletal myoblast cell line, ATCC CRL-1458 was carried out. In vitro antimicrobial assay revealed that 1-ethyl-7-methyl-4-oxo-N-(1,3,4,6-tetra-O-acetyl-2-deoxy-D-glucopyranose-2-yl)-[1,8]-naphthyridine-3-carboxamide (5) and 1-ethyl-7-methyl-4-oxo-N-(2-deoxy-D-glucopyranose-2-yl)-[1,8]-naphthyridine-3-carboxamide(6) possess growth inhibitory activity against resistant Escherichia coli NCTC, 11954 (MIC 0.1589 mM) and Methicillin resistant Staphylococcus aureus ATCC, 33591 (MIC 0.1589 mM). Compound (5) was more active against Listeria monocytogenes ATCC 19115 (MIC 0.1113 mM) in comparison with the reference nalidixic acid (MIC 1.0765 mM). Interestingly, compound (6) had potential antifungal activity against Candida albicans ATCC 10231 (MIC <0.0099 mM). Remarkably, the tested compounds had low cytotoxic effect. This study indicated that glucosamine moiety inclusion into the chemical structure of the marketed nalidixic acid enhances antimicrobial activity and safety. Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 3491-12-1.

Methods have been developed for the synthesis of new substituted 7,8,9,10-tetrahydro[1,2,4]triazolo-[3,4-a][2,7]naphthyridines from 3-chloro-1-hydrazino-7-methyl-5,6,7,8-tetrahydro-[2,7]naphthyridine-4-carbonitrile. It was shown that on heating in an amine (ethanolamine, pyrrolidine, 2-hydroxy-propylamine), they undergo a Dimroth rearrangement at the triazole fragment, being converted into 7,8,9,10-tetrahydro[1,2,4]triazolo[5,1-a][2,7]naphthyridine derivatives.

Various biologically relevant G-quadruplex DNA structures offer a platform for therapeutic intervention for altering the gene expression or by halting the function of proteins associated with telomeres. One of the prominent strategies to explore the therapeutic potential of quadruplex DNA structures is by stabilizing them with small molecule ligands. Here we report the synthesis of bisquinolinium and bispyridinium derivatives of 1,8-naphthyridine and their interaction with human telomeric DNA and promoter G-quadruplex forming DNAs. The interactions of ligands with quadruplex forming DNAs were studied by various biophysical, biochemical, and computational methods. Results indicated that bisquinolinium ligands bind tightly and selectively to quadruplex DNAs at low ligand concentration (similar to 0.2-0.4 mu M). Furthermore, thermal melting studies revealed that ligands imparted higher stabilization for quadruplex DNA (an increase in the T-m of up to 21 degrees C for human telomeric G-quadruplex DNA and >25 degrees C for promoter G-quadruplex DNAs) than duplex DNA (Delta T-m < 1.6 degrees C). Molecular dynamics simulations revealed that the end-stacking binding mode was favored for ligands with low binding free energy. Taken together, the results indicate that the naphthyridine-based ligands with quinolinium and pyridinium side chains form a promising class of quadruplex DNA stabilizing agents having high selectivity for quadruplex DNA structures over duplex DNA structures.

The dinuclear platinum(II) complexes, [{PtCl(NH3)(2)}(2)(mu-1,6-nphe)](ClO4)(2) (Pt1) and [{Pt(en)Cl}(2)(mu-1,6-nphe)](ClO4)(2) (Pt2) (en is a bidentate-coordinated ethylenediamine and 1,6-nphe is the bridging 1,6-naphthyridine ligand) were synthesized and characterized by different spectroscopic methods. The DNA-binding evaluation of complexes Pt1 and Pt2 was done by UV-Vis, fluorescence emission spectroscopy, and their interaction with bovine serum albumin (BSA). The cytotoxic activity of these complexes was determined against mouse breast (4T1) and colon (CT26) cancer cell lines, human breast (MDA-MB-468), colon (HCT-116), and lung (A549) cancer cell lines as well as mouse mesenchymal stem cells (mMSC). Complex Pt1 showed higher cytotoxic capacity toward solid cancer cell lines compared with Pt2 and lower cytotoxic capacity toward mMSC cells compared with cisplatin. Furthermore, molecular mechanism studies showed that Pt1 complex induced 4T1 and A549 cell apoptosis therefore increasing expression of pro-apoptotic caspase-3 and decreasing expression of anti-apoptotic Bcl-2 and Ki-67. Antitumor capacity of Pt1 complex might be manifested at least in two ways: by facilitating apoptosis and by inhibiting tumor cells proliferation.

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

Tetranuclear copper(I) complexes containing N,N’-bis(5,7-dimethyl-1,8-naphthyridine-2-yl)amine and phosphine ligands with close intramolecular Cu(I)center dot center dot center dot Cu(I) contacts were found to precipitate as thermodynamically stable and crystalline quasi-2D sheet-like nanostructures. Kinetically stable, amorphous, spherical particles were also identified during the precipitation/crystallization processes of these copper(I) complexes in a dichloromethane/hexane mixture. The distinct phosphorescent properties of these two forms of nanostructures were studied and a crystallization-induced emission enhancement was observed during the morphological evolution from amorphous spherical particles to crystalline nanosheets. All of these photophysical properties were rationalized by density functional theory calculations.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1185-55-3, in my other articles. Recommanded Product: 1185-55-3.

We report the synthesis of the azaoxoaporphine alkaloid sampangine (4) and a series of ring A analogues and isomers of the marine pyridoacridine alkaloid ascididemin (2). This approach starts from readily available 1-bromo[2,7] naphthyridine (12) or 4-bromobenzo[c][2,7] naphthyridine (5), and the ring A scaffold bearing an ester moiety is introduced by a Suzuki or Negishi cross-coupling reaction. The final cyclization step was achieved through a directed remote ring metallation with the Knochel-Hauser base (TMPMgCl center dot LiCl; TMP = 2,2,6,6-tetramethylpiperidinyl), followed by intramolecular trapping of the ester group.
