Fluorescent Short-Stranded Helical Foldamers Based on L-shaped Dibenzopyrrolo[1,2-a][1,8]naphthyridine

Helical structures were constructed by using pi-spacer-bridged dimers of dibenzopyrrolo[1,2-a][1,8]naphthyridine, which has a highly fluorescent L-shaped pi-extended skeleton. Three dimers with biphenylene (dimer 1), phenanthrene (dimer 2), and m-phenylene (dimer 3) spacers, as well as a fixed-helical dimer 4 where two quinolone rings were covalently cross-linked, were designed and prepared. H-1 NMR and ROESY spectra revealed that dimers 1 and 2 adopted helical forms in solution, whereas dimer 3 did not. The helical conformation of 1 was strengthened by addition of either polar or nonpolar solvents to the chloroform solution, which suggested that pi-pi stacking was the main contributor to the stabilization of the helical structure. All of the dimers, including fixed-helical dimer 4, emitted fluorescence with high quantum yields (phi=0.79-0.86).

A formal total synthesis of the marine alkaloid aaptamine

A new strategy for the synthesis of benzo[de][1,6]naphthyridine derivative 2,3,3a,4,5,6-hexahydroaaptamine, which involves the construction of the isoquinoline ring after elaboration of the quinoline moiety, is described. Since 2,3,3a,4,5,6-hexahydroaaptamine has been previously synthesized as a key intermediate en route to the marine alkaloid aaptamine, access to this compound represents a formal total synthesis of the natural product.

Selective G-quadruplex DNA Stabilizing Agents Based on Bisquinolinium and Bispyridinium Derivatives of 1,8-Naphthyridine

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.

Grignard Reagent Utilization Enables a Practical and Scalable Construction of 3-Substituted 5-Chloro-1,6-naphthyridin-4-one Derivatives

A robust, practical, and scalable approach for the construction of 3-substituted 5-chloro-1,6-naphthyridin-4-one derivatives 13 via the addition of Grignard reagents to 4-amino-2-chloronicotinonitrile (15) was developed. Starting with various Grignard reagents, a wide range of 3-substituted 5-chloro-1,6-naphthyridin-4-one derivatives 13 were conveniently synthesized in moderate-to-good yields through addition-acidolysis-cyclocondensation. In addition, the robustness and applicability of this synthetic route was proven on a 100 g scale, which would enable convenient sample preparation in the preclinical development of 1,6-naphthyridin-4-one-based MET-targeting antitumor drug candidates.

Spectroscopic Analysis and Dissolution Properties Study of Tosufloxacin Tosylate/Hydroxypropyl-beta-Cyclodextrin Inclusion Complex Prepared by Solution-Enhanced Dispersion with Supercritical CO2

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.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 620-92-8 help many people in the next few years. Formula: C13H12O2.
