Antimicrobial resistance is one of the greatest challenges facing the world today. In the United States alone, it is responsible for the death of more than 20,000 people each year. DNA gyrase, a well-validated drug target, is involved in bacterial DNA replication, repair and decatenation. Currently, the fluoroquinolone class of antibacterials act via inhibition of the DNA gyrase enzyme. However, their efficacy is hindered by the increasing incidence of antimicrobial resistance. Therefore, in this review, we provide an account regarding the structure of DNA gyrase and quinoline and non-quinolone inhibitors published within the last five years (2015-2019). Further, we also discuss molecular interactions and structureactivity relationship studies of the published inhibitors. (C) 2020 Elsevier Masson SAS. All rights reserved.

1,8-Naphthyridine derivatives have attracted considerable attention because they are the chief constituent of many compounds which have been isolated from natural sources, with various biological activities. Nalidixic acid, for example, possesses strong antibacterial activity and used mainly for the treatment of urinary tract infections with gram negative pathogens and Gemifloxacin has antimicrobial and antibacterial activities. It is known that (E)- and (Z)-o-(diethylamino)ethyl oximes of 1,8-naphthyridine series have the potential for use as local anesthetics and 1-(2-fluorobenzyl)-3-(2-tolyl)-1,8-naphthyridin-2(1H)-one is used for the treatment of memory disorders, in particular, Alzheimer’s disease. In recent years. research on derivatives of 1,8-naphthyridine has been intensive because these compounds show a wide range of biological activities. 2-Methyl-1,8-naphthyridine-3-carboxylate has been synthesized from ethyl-2-methyl-1,8-naphthyridine-3-carboxylate following two different procedures. The azide on heating with aliphatic and aromatic primaryamines in xylene underwent Curtius rearrangement to furnish the title compounds. They have been screened for their antimicrobial activity.

With the aim of evaluating interaction between double-stranded calf thymus (ds)DNA and sulphur containing fused planar rings, the derivatives of 1,8-naphthyridine containing thiono groups were synthesized by the condensation of 2-mercapto-3-formyl[1,8]naphthyridines using 1-chloroacetone, 2-chloroacetamide, chloroaceticacid, and 2-chloro-1-phenylethanone in the presence of anhydrous potassium carbonate as s catalyst under solvent free microwave irradiation. The structures of the compounds were elucidated on the basis of elemental analysis, IR, H-1 NMR, and mass spectra. The interaction of thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (TNC) (3a) with ct-DNA was studied by UV-Vis spectrophotometry, viscosity, thermal denaturation, as well as cyclic voltammetry experiments. On binding to DNA, the absorption spectrum underwent bathochromic and hypochromic shifts. Binding parameters, determined from spectrophotometric measurements indicated a binding constant of K-b = 2.1 x 10(6) M-1. The thieno[2,3-b]-1,8-naphthyridine-2-carboxylic acid (3a) increases the viscosity of sonicated rod-like DNA fragments. The binding of TNC to DNA increased the melting temperature by about 4 degrees C. The decrease in peak current heights and shifts of peak potential values are observed by the addition of calf thymus DNA in cyclic voltammetry studies.

A new rhodamine-based derivative bearing a naphthyridine group (compound 1) was synthesized as a colorimetric and fluorescent off-on chemosensor for Cu2+ in aqueous solutions. The sensing behaviors of 1 toward various metal ions in neutral aqueous solutions were investigated by absorption and fluorescence spectroscopies. Compound 1 is found to exhibit a significant increase in absorbance at 561 nm and an amplified fluorescence at 590 nm toward Cu2+ in a selective, sensitive and rapid manner. The quantification of Cu2+ by 1 using an absorption spectroscopy method was satisfactory in the linear working range 0.9-10 mu M, with a detection limit of 5.4 x 10(-8) M for Cu2+ and good tolerance of other metal ions. Upon addition of Cu2+, the spirolactam ring (colorless and nonfluorescent) of 1 was opened to ring-opened amide (red color and fluorescent) and a 1:1 stoichiochemetry for the 1-Cu2+ complex was formed with an association constant of 1.57 x 10(4) M-1.

Mononuclear complexes of 1:1 and 1:2 composition, namely, [Nd(L)(NO3)(3)] (1a), [Nd(L)(NO3)(3)]center dot H2O (1b), [Lu(L)(NO3)(2)(H2O)](NO3) (2), [Nd(L)(2)(NO3)(2)(H2O)](NO3) (3), [Lu(L)(2)(NO3)(H2O)](NO3)(2)center dot 0.75CH(3)CN center dot H2O (4a) and [Lu(L)(2)(NO3) (H2O)](NO3)(2) (4b) were synthesized and studied by IR, Raman, and P-31 NMR spectroscopy in solid state and in solution. Structures of the complexes 1b and 4a were determined by X-ray diffraction. According to X-ray crystallography, vibrational spectroscopy and C, H, N, P elemental analysis data in solid 1:1 complexes one neutral molecule of L serves most likely as O,O,N,N-tetradentate ligand while in the 1:2 complexes only one ligand molecule coordinates in the same O,O,N,N-tetradentate fashion, and the second one serves as O-monodentate one. In solution the coordination mode of the ligand is preserved in all complexes. (C) 2011 Elsevier B. V. All rights reserved.
