High resolution fluorine-19 NMR spectra of polyfluoroaromatic compounds dissolved in deuterated dimethyl sulphoxide were measured and substituent shielding parameters were derived.These parameters were compared with the values observed in deuterated chloroform solutions and used to identify fluoroaromatic compounds related to perfluorinated polyimides and poly(amic acids)s.Average differences of Deltadelta between the solvents are 1.1, 1.0 and 2.1 ppm for o-, m- and p-fluorines of monosubstituted pentafluorobenzenes, respectively.The significant difference for p-fluorine of NH2 is important in identifying perfluorinated diamines because they are source materials for perfluorinated polyimides.Substituent shielding parameters for meta and para substitution increase as the respective Hammett ? constants increase, which indicates that fluorine-19 NMR chemical shift is primarily determined by electron density. – Keywords: NMR; 19F NMR; substituent shielding parameter; fluoroaromatic compounds; perfluorinated polyimides; Hammett ? constant

DNA gyrase of Mycobacterium tuberculosis (MTB) is a type II topoisomerase and is a well-established and validated target for the development of novel therapeutics. By adapting the medium throughput screening approach, we present the discovery and optimization of ethyl 5-(piperazin-1-yl) benzofuran-2- carboxylate series of mycobacterial DNA gyraseB inhibitors, selected from Birla Institute of Technology and Science (BITS) database chemical library of about 3000 molecules. These compounds were tested for their biological activity; the compound 22 emerged as the most active potent lead with an IC50 of 3.2 ± 0.15 muM against Mycobacterium smegmatis DNA gyraseB enzyme and 0.81 ± 0.24 muM in MTB supercoiling activity. Subsequently, the binding of the most active compound to the DNA gyraseB enzyme and its thermal stability was further characterized using differential scanning fluorimetry method.

Computed Properties of C16H8FNO2

Quinoxaline derivatives 4-11 were synthesized and evaluated for their in vitro growth inhibitory activities against liver carcinoma cell line (HEPG2) using the sulforhodiamine B assay. The synthesis was achieved by reaction of 2,3-dichloroquinoxalines 2a,b with 4-aminoacetophenone to give the corresponding compounds 3a,b. Claisen-Schmidt condensation reaction of 3a,b with furfuraldehyde gave enones 4a,b, which were transformed into pyridines 6a,b, 8a,b, isoxazolines 9a,b, pyrazolines 10a-d, and pyrimidines 11a,b via several synthetic routes. Virtual screening was carried out by molecular modeling evaluation of the designed compounds. Biological evaluation of the prepared compounds showed that most of the synthesized compounds exhibit more than 50% growth inhibitory.

The development of a clear chemical process to produce diverse value-added chemicals from low-cost raw materials is a particularly attractive concept and represents a considerable challenge in sustainable organic synthesis. Herein, two highly efficient and clear methods for the synthesis of quinolone derivatives based on a linear/branched domino protocol under sustainable conditions were established. The main advantages of these protocols are the simple experimental procedure, high bond-forming efficiency, inexpensive readily available starting materials, moderate to excellent yields with good functional group compatibility, and nonchromatographic purification, which render these methods particularly attractive for the sustainable preparation of biologically and medicinally interesting molecules. To demonstrate the practical utility of our protocol, existing pharmaceutical sarafloxacin was successfully synthesized. Furthermore, a postulated reaction pathway including condensation reaction/nucleophilic aromatic substitution/Friedel-Crafts reaction for these domino reactions is also discussed.
