Design, synthesis, and biological evaluation of 1,8-naphthyridine glucosamine conjugates as antimicrobial agents

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.

Metal-metal bonding in 1st, 2nd and 3rd row transition metal complexes: a topological analysis

A topological analysis based on density functional electronic and spin densities of the bonding characteristics in a series of Fe, Ru, Os, Tc and Rh dimers and trimers bridged, respectively, by mu-1,8-naphthyridine (nap) and mu-2,2′-dipyridylamine (dpa) is presented. By this simple qualitative analysis, we were able to determine the electronic ground state and correlated bonding order for a number of complexes potentially involved in extended metal atom chains (EMAC). Furthermore, we showed in the Ru dimer that it was possible to control the spin state simply by changing the bonded counter-anion.

Synthesis and Complexation Behavior of Indenyl and Cyclopentadienyl Ligands Functionalized with a Naphthyridine Unit

Lithium indenide (Li-Ind) or cyclopentadienide (Li-Cp) derivatives react as nucleophiles with 8-(methylsulfinyl)-1,5-naphthyridine (Naph), leading to donor-functionalized ligands Ind(Naph) or Cp-Naph, respectively. The new ligands comprise two N-donor atoms, which, for geometric reasons, cannot bind to the same metal atom. In complexes, where the metal atom is bound by the Cp or Ind moiety, the N5-donor atom is located in a distal position. The coordination behavior to Rh or Zr metal centers has been investigated. The Cp-based ligands show the expected chelating coordination mode with eta(5)-Cp and N coordination, whereas the indenyl units act as dihapto, trihapto, or pentahapto ligands. The dinuclear Rh(I) complex 12 shows a rare coordination geometry with two eta(3) ligands bridging a Rh-2(CO)(3) fragment.

Aromatic Helical Foldamers as Nucleophilic Catalysts for the Regioselective Acetylation of Octyl beta-d-Glucopyranoside

Two indolocarbazole-naphthyridine foldamers 2 and 3 that fold into helical conformations were prepared. The 4-(N,N-dimethylamino)pyridine (DMAP) moiety was introduced at one end of the foldamer strands to develop foldamer-based catalysts for the site-selective acylation of polyols. These foldamers adopt helical conformations containing internal cavities capable of binding octyl beta-d-glucopyranoside. The association constants were determined to be 1.9 (+/- 0.1)x10(5) M-1 for 2 and 2.1 (+/- 0.1)x10(5) M-1 for 3 in CH2Cl2 at 25 degrees C. In the presence of DMAP, 2 or 3 as the catalysts, octyl beta-d-glucopyranoside was subjected to acetylation under identical reaction conditions. The DMAP-catalysed reaction afforded the random distribution of the monoacetylates (6-OAc : 4-OAc : 3-OAc : 2-OAc=33 : 24 : 41 : 2). In contrast, foldamers 2 and 3 led to the predominant formation of 6-OAc. The relative distributions were estimated to be 6-OAc : 4-OAc : 3-OAc=88 : 4 : 6 : similar to 0 with 2 and 6-OAc : 4-OAc : 3-OAc : 2-OAc=90 : 3 : 6 : 1 with 3.

Exploring the Role of Water Molecules for Docking and Receptor Guided 3D-QSAR Analysis of Naphthyridine Derivatives as Spleen Tyrosine Kinase (Syk) Inhibitors

In the present study, 3D-QSAR analysis was performed utilizing docking based alignment of [1,6]-naphthyridine derivatives as Syk enzyme inhibitors. The role of the water molecules was explored for the docking based alignment that revealed two conserved water molecules important for proper orientation and alignment of naphthyridine inhibitors in the active site of Syk enzyme. The QSAR model was selected having highest value of Q(2) (0.624) and Pearson-r (0.862). The selected model also displayed the highest values of R-2 (0.978) and F-value (184.5) and the lowest SD (0.862). The contour plots developed on the basis of the best model helped to reveal the essential structural features of naphthyridines derivatives responsible for inhibition of Syk enzyme. The generated model and information revealed from it was utilized to design and predict new congeneric molecules that can be used as potential therapeutic agents.

Ruthenium(II)-carbonyl complexes containing two N-monodentate 1,8-naphthyridine ligands: active catalysis in transfer hydrogenation reactions

The reaction of 2-aminonicotinaldehyde with 2- or 4-methoxyacetophenone in basic media leads to the new ligands 2-(4-methoxyphenyl)-1,8-naphthyridine and 2-(2-methoxyphenyl)-1,8-naphthyridine, respectively, in high yield. The reaction of these naphthyridine derivatives with [RuCl2(CO)(2)](n) leads to the respective complexes cis-dicarbonyldichloridobis[2-(4-methoxyphenyl)-1,8-naphthyridine-kappa N-8]ruthenium(II) and cis-dicarbonyldichloridobis[2-(2-methoxyphenyl)-1,8-naphthyridine-kappa N-8]ruthenium(II), both [RuCl2(C15H12N2O)(2)(CO)(2)], in good yield. Both ruthenium(II) complexes display a slightly distorted octahedron with two cis carbonyl, two cis chloride and two cis naphthyridine ligands, the latter coordinated in a monodentate fashion through the N atom in the 8-position.
