A series of 3-, 4- and 5-aminomethyl isoxazoles and isoxazoles with one or two additional methyl groups at the heterocycle were synthesized in order to investigate the structural requirements, ie heterocyclic moiety, regiochemistry and length of an aminoalkyl unit, for muscarinic activity. This was assayed on isolated rabbit vas deferens (M1 receptor subtype) and isolated guinea-pig atrium (M2 receptor subtype) and ileum (M3 receptor subtype). The isoxazoles tested are one to three orders of magnitude less active than furane or oxadiazole derivatives, having similar structural characteristics except for the heterocycle. Thus, the differences in molecular point charges and charge distribution contribute to the muscarinic activity of these compounds more than small differences in molecular shape and conformational energies.

Based on the wide range of various biological activities of benzosuberone derivatives and the emergence of multidrug resistance (MDR) of the continued use of antibiotics among different breeds microorganisms, we synthesized herein a new series of benzosuberone derivatives via the reaction of 6-((5-methylfuran-2-yl)methylene)-6,7,8,9-tetrahydro-5H-benzo[7] annulen-5-one with nuecluophilic nitrogen compounds and hydrazonoyl halides. The structures of the new compounds were elucidated based on their IR, 1H-NMR and Mass spectra. Moreover, the potency of these compounds as antimicrobial agents has been evaluated. The results showed that some of the products have high activity exceed the used standard antibiotic. Additionally, the docking study was done to get the binding mode of the synthesized compounds with the binding site of the topoisomerase II enzyme. The results of molecular docking showed that the most active six derivatives are capable to fit in the binding pocket of topoisomerase II with binding energies ranging from ?4.61 to ?6.16 Kcal/mol.

Ethyl bromodifluoroacetate (BrCF2COOEt) was first used as the N-formylating reagent in the copper-catalyzed N-formylation of amines. A range of primary, secondary, cyclic arylamines, and aliphatic amines underwent the N-formylation smoothly to furnish the N-formamides in moderate-to-excellent yields.

In this study, nitrogen, sulfur and oxygen co-doped carbon armored cobalt sulfide (Co/Co9S8@N-S-O-C) composite was synthesized, characterized and used to activate peroxymonosulfate (PMS) for the degradation of sulfamethoxazole (SMX). SMX (0.04 mM) can be completely degraded within 20 min in the presence of 0.8 mM PMS and 0.1 g/L Co/Co9S8@N-S-O-C composite. The first-order kinetics constant of SMX degradation was 0.307 min-1, and the mineralization of SMX was 30.1 %. The Quenching experiments of the free radicals and the identification of degradation products demonstrated that sulfate radicals played a dominant role in SMX degradation. The degradation rate of SMX increased with temperature, and activation energy was calculated to be 48.6 kJ/mol. The degradation rate of SMX increased firstly then decreased with increase of pH. Chloridion and humic acid decreased the degradation rate of SMX no matter what their initial concentration was. The effect of carbonate on SMX degradation depended on its initial concentration. Co/Co9S8@N-S-O-C composite showed good stability, the removal efficiency of SMX was 98.4 % in the fifth experiment. Based on the characterization results of the catalyst before and after use, it was concluded that cobalt, sulfur, pyridnic N and graphitic N were responsible for PMS activation.

The sharp rise in antimicrobial resistance has been matched by a decline in the identification and clinical introduction of new classes of drugs to target microbial infections. Thus new approaches are being sought to counter the pending threat of a post-antibiotic era. In that context, the use of non-growth limiting small molecules, that target virulence behaviour in pathogens, has emerged as a solution with real clinical potential. We have previously shown that two signal molecules (HHQ and PQS) from the nosocomial pathogen Pseudomonas aeruginosa have modulatory activity towards other microorganisms. This current study involves the synthesis and evaluation of analogues of HHQ towards swarming and biofilm virulence behaviour in Bacillus atrophaeus, a soil bacterium and co-inhibitor with P. aeruginosa. Compounds with altered C6-C8 positions on the anthranilate-derived ring of HHQ, display a surprising degree of biological specificity, with certain candidates displaying complete motility inhibition. In contrast, anti-biofilm activity of the parent molecule was completely lost upon alteration at any position indicating a remarkable degree of specificity and delineation of phenotype.

Constructed wetlands (CWs) could achieve high removal efficiency of antibiotics, but probably stimulate the spread of antibiotic resistance genes (ARGs). In this study, four CWs were established to treat synthetic wastewater containing sulfamethoxazole (SMX). SMX elimination efficiencies, SMX degradation mechanisms, dynamic fates of ARGs, and bacterial communities were evaluated during the treatment period (360 day). Throughout the whole study, the concentration of SMX in the effluent gradually increased (p < 0.05), but in general, the removal efficiency of SMX remained at a very high level (>98%). In addition, the concentration of SMX in the bottom layer was higher compared with that in the surface layer. The main byproducts of SMX degradation were found to be 4-amino benzene sulfinic acid, 3-amino-5-methylisoxazole, benzenethiol, and 3-hydroxybutan-1-aminium. Temporally speaking, an obvious increase of sul genes was observed, along with the increase of SMX concentration in the bottom and middle layers of CWs. Spatially speaking, the concentration of sul genes increased from the surface layer to the bottom layer.
