Purpose The aim of this study was to prepare tosufloxacin tosylate (TFLX) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) inclusion complexes by solution-enhanced dispersion with supercritical CO2 (SEDS) and optimize process parameters, in vitro dissolution evaluation, and determination of inclusion sites. Methods The effects of operating pressure, operating temperature, drug concentration, and solution flow rate on the particle size and morphology of the inclusion complex were analyzed by a single factor design experiment. The SEDS-prepared inclusion complex was characterized by TG/DSC, XRD, SEM, FT-IR, H-1 NMR, 2D-ROESY, and MD and measured for in vitro dissolution, solubility, and antibacterial activity. Results The optimum drug concentration was 40 mg/mL and pressure 16 MPa, temperature 35 degrees C, and solution flow rate 1 mL/min; under this condition, the mean particle size of the inclusion complex was 1.91 mu m. All characterization results confirmed the formation of an amorphous inclusion complex and the sites where TFLX and HP-beta-CD bind through the H-bond were located on the aromatic B ring, pyrrolidine, and naphthyridine ring protons. Furthermore, the solubility of the inclusion complex (489.87 mu g/mL) was significantly higher than that of TFLX, and the dissolution rate of TFLX increased from the initial 13.99 to 61.04% in ultrapure water. In vitro study showed that the inclusion complex maintained the antibacterial effect of TFLX. Conclusion TFLX/HP-beta-CD inclusion complex prepared by manipulating SEDS process conditions could significantly improve the dissolution and solubility of the water-insoluble TFLX.

Novel N’-(2-hydroxy-3-methoxy-benzylidene)-1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbohydrazide [NBNCH] and its solid metal complexes with Cu-II, Ni-II and Co-II were synthesized and characterized by employing spectro-analytical techniques viz. elemental analyses, magnetic susceptibilities measurements, H-1 NMR, UV-Vis, IR, Mass, TGA, SEM-EDX, ESR and spectrophotometry studies. The HyperChem 7.5 software was used for quantum mechanical calculations. The geometry optimization, contour maps of highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) and corresponding binding energy values of molecular and ionic forms of title compound were computed using semi empirical single point PM3 method, in order to understand the binding modes of metal complexes. The stoichiometric studies of complexes determined spectrophotometrically using Job’s continuous variation and mole ratio methods inferred 1:2 ratio in respective systems. The title compound and its metal complexes screened for antibacterial and antifungal properties indicated more pronounced activity of Cu-II complex compared to other compounds. The studies of nuclease activity for the cleavage of PBR322 DNA and MTT assay for in vitro cytotoxic properties showed high activity of Cu-II complex. The interaction studies of metal complexes with CT-DNA investigated by UV-Visible and fluorescence titrations revealed the intercalation mode of binding. Docking studies were also performed to illustrate the binding mode of the title compound with the target site of Thymidine phosphorylase from E. coli (PDB ID: 4EAF) protein.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

The catalytic performance of Ru-NAD-type complexes [Ru(tpy)(pbn)(CO)(2+) ([1](2+); tpy = 2,2′;6′,2 ”-terpyridine; pbn = 2-(pyridin-2-yl)benzo[b][1,5]naphthyridine) and the Ru-CO-bridged metallacycle [2](+) was investigated in the context of the electrochemical reduction of CO2 in H2O/CH3CN at room temperature. A controlled-potential electrolysis of [1](2+) and [2](+) afforded formate (HCOO-) as the main product, under concomitant formation of minor amounts of CO and H-2. Metallacycle [2](+) showed a higher selectivity toward the formation of HCOO- than [1](2+) (HCOO-/CO for [1](2+), 2.7; HCOO-/CO for [2](+), 7). The generation of HCOO- via a catalytic hydride transfer from the NADH-type ligands of [1](2+) and [2](+) to CO2 was supported by the experimental results and a comparison with the reduction of CO2 catalyzed by [Ru(tpy)(bpy)(CO)](2+) under similar conditions. A mechanism for the catalytic reduction of CO2 by [1](2+) and [2](+) was proposed based on the experimental evidence. The thus-obtained results may help to expand the field of NADH-assisted reduction reactions.

A novel fluorescent chemodosimeter based on 1,8-naphthyridine exhibits high selectivity to Zn2+ and Cu2+. When 1-(7-acetamino-1,8-naphthyridyl)2-(6-diacetaminopyridyl)ethene was mixed with CuCl2, hydrolysis of the acetamino group catalyzed by Cu2+ complex was first observed. Resulting from coordination and hydrolysis catalyzed by the corresponding complex of Zn2+ or Cu2+, the highly effective fluorescent detection of Zn2+ and Cu2+ is realized with Zn2+-selective dual-emission and Cu2+-selective ON-OFF behavior.

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.

Structurally diverse inhibitors of the protein kinase CK2 are required for regulation of this ubiquitous protein to establish biological roles of the enzyme which catalyzes the phosphorylation of a vast number of substrate proteins. In this article we disclose a series of new bisubstrate inhibitors of CK2 that are structurally represented by the oligo(L-Asp) peptide conjugates of benzo[c][2,6]naphthyridine-8-carboxylic acid. This fragment originated from CX-4945, the first in class inhibitor taken to clinical trials. The most potent conjugates possessed two-digit picomolar affinity and clear selectivity for CK2 alpha in a panel of 140 protein kinases. Labeling of the inhibitors with a fluorescent dye yielded probes for a fluorescence anisotropy-based binding/displacement assay which can be used for analysis of CK2 and precise determination of affinity of the highly potent (tight-binding) CK2-targeting inhibitors.
