A 2-amino-1,8-naphthyridine derivative that is described to bind single guanine bulges in RNA-DNA and RNA-RNA duplexes was synthesized and its interaction with the single G bulge in the conserved CREX of the Hepatitis E Virus (HEV) genome was explored by NMR and molecular modeling. Results indicate that the ligand intercalates in the internal loop, though none of the expected hydrogen bonds with the single G in the bulge could be demonstrated.

Water-soluble donor-acceptor-type fluorophore 15Nap-Cl having two trifluoromethyl groups and a Cl group on a 1,5-aminonaphthyridine framework was prepared. Fluorophore 15Nap-Cl showed strong solvatochromic fluorescence, and, as the solvent polarity increased, a bathochromic shift was observed accompanied by an increase in the fluorescence quantum yield. In addition, in the presence of amines such as ethylamine, diethylamine, and aniline, further considerable bathochromic shifts in the fluorescence were observed. Density functional calculations identified the source of the fluorescence behavior as exciplex formation between 15-Nap-Cl and the corresponding amine. The fluorescence behavior was exploited to fabricate a sensor that can identify various primary, secondary, and tertiary amines.

Naphthyridines represent a class of heterocyclic compounds formed by two condensed aromatic rings. This study aimed to evaluate the antibacterial activity and in vitro inhibition of efflux resistance mechanisms of a series of 1,8-naphthyridine sulfonamides against strains carrying Tet(K) and MsrA efflux pumps. The efflux pump inhibitory capacity was evaluated by analyzing synergistic effects between 1,8-naphthyridine sulfonamides and standard antibiotics, as well as ethidium bromide. The following 1,8-naphthyridines were used: 4-methyl-N-(5-chloro-1,8-naphthyridin-2-yl)-benzenesulfonamide (Naph 1); 2,5-Dichloro N (5-chloro-1,8-naphthyridin-2-yl)-benzenesulfonamide (Naph 2); 2,3,4-trifluoro-N-(5-chloro-1,8-naphthyridin-2-yl)-benzenesulfonamide (Naph 7); 3-trifluoromethyl-N-(5-chloro-1,8-naphthyridin-2-yl)-benzenesulfonamide (Naph 9). The 1,8-naphthyridine sulfonamide derivatives possessed a potential Tet(K) and MsrA efflux pump inhibitory action.

In a document, author is Yu, Mingming, introduce the new discover.

Based on Rhodamine B, two Al3+/Cu2+-selective chemosensors were synthesized, which display a high selectivity for Al3+ and Cu2+ among environmentally and biologically relevant metal ions. A 1,8-Naphthyridine modified rhodamine derivative can detect Al3+ in ethanol with off-on fluorescence behavior, and detect Cu2+ in aqueous solution with colorimetric method. The 8-Hydroxyquinoline-based rhodamine sensor can detect Al3+ in ethanol with both off-on fluorescence and colorimetric methods. The detection mechanism involves a ring-opening process as a consequence of metal complex formation. Job’s plots and a time-of-flight mass spectral study indicated that each chemosensor chelated Al3+/Cu2+ with 1:1 stoichiometry. The binding of the chemosensors and Al3+/Cu2+ is chemically reversible by the addition of F-/EDTA solution, respectively. (C) 2013 Elsevier Ltd. All rights reserved.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 82-76-8 is helpful to your research. Category: naphthyridines.

Stepwise changes of functional oxo and amino groups in 1,8-naphthyridines to modify the supramolecular architecture have been carried out. The first example of a naphthyridine helix has been found and its structure established by X-ray crystallography. The design is based on hydroxy and amido tautomeric naphthyridines which crystallize in dimers or catemers, one of them attaining helicity. The most stable tautomer present in all the compounds discussed in this paper, as well as the formation of hydrogen-bonded dimers or catemers, was established by X-ray crystallography and rationalized with theoretical calculations.
