N,N-Dialkyl-N′-Chlorosulfonyl Chloroformamidines in Heterocyclic Synthesis. Part XI. Some Substitution Reactions of Pyrazolo[1,5-b][1,2,4,6]thiatriazine 1,1-Dioxides 
Rebecca E. Norman, Michael V. Perkins, Andris J. Liepa and Craig L. Francis

The pyrazolo[1,5-b][1,2,4,6]thiatriazine template possesses four nucleophilic sites, N2, N4, C5, and N7. Alkylation occurred predominantly at N4 and N7. The N-7 alkylation products from α-halo esters underwent pyrazole ring expansion, affording pyrimido[1,6-b][1,2,4,6]thiatriazine derivatives. Bromination and tosylation afforded unstable C5-substituted derivatives. Treatment of N7-benzylated pyrazolo[1,5-b][1,2,4,6]thiatriazines with acid caused extrusion of SO2 affording pyrazolo-guanidines.

3D Synthetic Soft Tissue as a Novel Anti-Biofilm Assay for Drug Screening 
Darryl Nguyen

Current standard antibiotic screening protocols lack a reliable in vitro method to assess antimicrobial susceptibility, largely due to lack of comparability with the in vivo environment of microbial biofilm infections. These limitations can be addressed by replicating the in vivo substratum by utilising 3D synthetic soft tissue, a readily synthesised substratum that emulates chronic wound infections.

Breathing crystals based on complexes of Cu(hfac)2 (hfac = hexafluoroacetylacetonate) with nitronyl nitroxides demonstrate a variety of structural rearrangements and accompanying magnetic phenomena. We report on the synthesis of diamagnetic analogues of nitronyl nitroxides that are able to isostructurally substitute the latter in copper-nitroxide systems. Such substitution leads to the disappearance of the rearrangements characteristic of breathing crystals.

Dengping Hu, Guangyao Zhang, Juan Wang and Qin Zhong

Pt/C is widely used for oxygen reduction reaction (ORR) in microbial fuel cells (MFCs). However, its high cost, scarcity, and poisoning sensitivity hinder further commercialization of MFCs. Carbon-supported spinel MnCo2O4 shows comparable ORR catalytic activity to Pt/C. It can be a promising alternative to Pt/C in commercialising MFCs due to its low cost, easy availability, high stability, high efficiency, and low toxicity.

Although few contacts were identified with DNA nucleobase π-systems, many interactions involve the aromatic amino acids, thus adding to the list of π-contacts that must be considered when analyzing the binding patterns and/or stability of biological macromolecules.

The Influence of Water and Metal Salt on the Transport and Structural Properties of 1-Octyl-3-methylimidazolium Chloride 
Nicolas Goujon, Nolene Byrne, Tiffany R. Walsh and Maria Forsyth

We show the influence that two metal salts, zinc chloride and magnesium chloride, have on the transport properties of the nanostructured 1-methyl-3-octylimidazolium chloride, OMImCl, at varying water concentrations. The impact the metal salts have on the transport properties is directly related to their water structuring or destructing capabilities.

pp. 288-297

Because ZnO and Ag nanoparticles (NPs) effectively inhibit foodborne pathogens, both metals are expected to produce a more effective inhibitor as a result of hybrid properties. It has been reported that Ag-doped ZnO NPs and ZnO NPs do not show much difference in antibacterial activities, but show an increase in bacterial inhibition. To explain why doping of Ag NPs, unlike Au NPs, in ZnO NPs influences the antibacterial activities, ZnO, ZnO–Ag, and ZnO–Au NPs were synthesized.
