Catalytic Reduction of Graphene Oxide Nanosheets by Glutathione Peroxidase Mimetics Reveals a New Structural Motif in Graphene Oxide
Authors: Vernekar Amit A. , Mugesh Govindasamy 
Published: November 2013

AbstractA catalytic reduction of graphene oxide (GO) by glutathione peroxidase (GPx) mimics is reported. This study reveals that GO contains peroxide functionalities, in addition to the epoxy, hydroxyl and carboxylic acid groups that have been identified earlier. It also is shown that GO acts as a peroxide substrate in the GPx‐like catalytic activity of organoselenium/tellurium compounds. The reaction of tellurol, generated from the corresponding ditelluride, reduces GO through the glutathione (GSH)‐mediated cleavage of the peroxide linkage. The mechanism of GO reduction by the tellurol in the presence of GSH involves the formation of a tellurenic acid and tellurenyl sulfide intermediates. Interestingly, the GPx mimics also catalyze the decarboxylation of the carboxylic acid functionality in GO at ambient conditions. Whereas the selenium/tellurium‐mediated catalytic reduction/decarboxylation of GO may find applications in bioremediation processes, this study suggests that the modification of GO by biologically relevant compounds such as redox proteins must be taken into account when using GO for biomedical applications because such modifications can alter the fundamental properties of GO.

Poly(ethylene oxide)‐graft‐methotrexate Macromolecular Drugs Conjugating via Aminopteridine Ring Exhibit Potent Anticancer Activity
Authors: Guo Weiwei , Zheng Meng , Zhong Yinan , Meng Fenghua , Deng Chao , Zhong Zhiyuan 
Published: November 2013

AbstractWater soluble poly(ethylene oxide)‐graft‐methotrexate (PEO‐g‐MTX) conjugates with a robust amide linkage via the amine or carboxylic acid groups of MTX were designed, prepared and investigated for in vitro anti‐tumor effects. MTX was conjugated to multi‐functional PEO containing multiple pendant carboxylic acid (PEO‐g‐COOH) or amine groups (PEO‐g‐NH2) via the carbodiimide chemistry, which afforded PEO‐g‐MTX conjugates with an amide bond to the aminopteridine ring or carboxylic acid groups of MTX (denoted as PEO‐g‐MTX(COOH) and PEO‐g‐MTX(NH2), respectively). Dynamic light scattering (DLS) revealed that all PEO‐g‐MTX conjugates, with MTX contents varying from 4.8 to 19.6 wt%, existed as unimers in phosphate buffer (PB, pH 7.4, 20 mmol·L−1). Interestingly, MTT assays showed that PEO‐g‐MTX(COOH) exhibited potent anti‐tumor activity in HeLa, A549, KB and NIH3T3 cells with cytotoxicity profiles comparable to that of free MTX. In contrast, PEO‐g‐MTX(NH2) revealed diminishing cytostatic effect with IC50 (half maximal inhibitory concentration) ten to hundred times higher than that of PEO‐g‐MTX(COOH). Moreover, PEO‐g‐MTX(COOH) conjugates allowed facile conjugation with targeting ligands. Notably, folate‐decorated PEO‐g‐MTX(COOH) macromolecular drugs showed apparent targetability to folate receptor‐overexpressing KB cells with an IC50 over 12‐fold lower than non‐targeting PEO‐g‐MTX(COOH) control and about 2‐fold lower than free MTX under otherwise the same conditions.

Published: November 2013

AbstractSpiropyran thin film with capability of light‐triggered molecular level self‐healing has been successfully designed and fabricated by Langmuir‐Blodgett technology. Various remarkable properties of thin film shrinkage or height increase or self‐healing nano‐defect recovery under different fabrication conditions have been observed. In addition, further evidence of the self‐healing, which resulted from the movement of spiropyran molecules (such as "standing" "lie‐down" and "tip‐toes" etc.) on the substrate, has also been observed from the reversible contact angle change of the thin film.

AbstractWe have conducted systematic structural modification, deconstruction, and reconstruction of the berberine core with the aim of lowering its cytotoxicity, investigating its pharmacophore, and ultimately, seeking novel synergistic agents to restore the effectiveness of fluconazole against fluconazole‐resistant Candida albicans. A structure–activity relationship study of 95 analogues led us to identify the novel scaffold of N‐(2‐(benzo[d][1,3]dioxol‐5‐yl)ethyl)‐2‐(substituted phenyl)acetamides 7 a–l, which exhibited remarkable levels of in vitro synergistic antifungal activity. Compound 7 d (N‐(2‐(benzo[d][1,3]dioxol‐5‐yl)ethyl)‐2‐(2‐fluorophenyl)acetamide) significantly decreased the MIC80 values of fluconazole from 128.0 μg mL−1 to 0.5 μg mL−1 against fluconazole‐resistant C. albicans and exhibited much lower levels of cytotoxicity than berberine toward human umbilical vein endothelial cells.

Published: November 2013

AbstractThe development of technologies to tune lignin properties for high‐performance lignin‐based materials is crucial for the utilization of lignin in various applications. Here, the effect of methanol (MeOH) fractionation on the molecular weight, molecular weight distribution, glass transition temperature (Tg), thermal decomposition, and chemical structure of lignin were investigated. Repeated MeOH fractionation of softwood Kraft lignin successfully removed the low‐molecular‐weight fraction. The separated high‐molecular‐weight lignin showed a Tg of 211 °C and a char yield of 47 %, much higher than those of as‐received lignin (Tg 153 °C, char yield 41 %). The MeOH‐soluble fraction of lignin showed an increased low‐molecular‐weight fraction and a lower Tg (117 °C) and char yield (32 %). The amount of low‐molecular‐weight fraction showed a quantitative correlation with both 1/Tg and char yield in a linear regression. This study demonstrated the efficient purification or fractionation technology for lignin; it also established a theoretical and empirical correlation between the physical characteristics of fractionated lignins.

ABSTRACTDischarge fluctuation and extreme bed load movement, i.e. erosion and sedimentation occurring on short upper reaches of the river, are characteristic features of torrential rivers. This paper presents a biotechnical appraisal of a torrent catchment for implementing revetments methods, focusing on selected hydraulic characteristics of the flow. The Infiltration and Kinematic wave hydrological model (KINFIL) hydrological model (for design discharges) is used to verify these variables and also the Hydrologic Engineering Centre's River Analysis System and Sedimentation and River Hydraulics Two‐Dimensional hydraulic models for channel flow. Data and computation for proposing nature‐close remedial measures are demonstrated in a case study of the Jindrichovicky Brook, a mountain torrent located in the Ore Mountains (Czech Republic).Particular attention is given to appropriate adaptation of the river for the invertebrate community. The hydraulic analysis is carried out in two sections of the river (section A: ‘nature‐close’, restored in 2008, and section B: ‘old style’, regulated in the 1970s). The aim is to compute the major hydraulic characteristics (depths, velocities, shear stress values etc.). Then, a hydrobiological investigation is carried out in both sections to find how much the invertebrate communities extended their diversity and abundance as a consequence of better geomorphological diversity after restoration. It was found that, from the hydraulic point of view, the old section B is sufficiently robust and stable. However, it is clearly evident that this section can hardly be populated by fauna and if so, then only very sparsely and impermanently. Section A meets both priorities, hydraulic stability and an acceptable living environment for the benthic community. Copyright © 2013 John Wiley & Sons, Ltd.
Simultaneous Synthesis of Polyoxometalates and Metal Nanoparticles from Molecular Precursors – Redox‐Active Microreactors and Functional Nanomaterials
Authors: Mitchell Scott G. , de la Fuente Jesús M. 
Published: November 2013

AbstractInvited for the cover of this issue are Scott Mitchell and Jesús Martínez de la Fuente of The Nanotherapy and Nanodiagnostics Group from the Institute of Nanoscience of Aragón, part of the University of Zaragoza (Spain). The cover image shows a false colored SEM image of triangular gold nanoprisms (we refer to them as “nanonachos”), which can be synthesized by using paradodecatungstate [H4W12O42]8–. The distinctive green color of the nanonachos is due to their localized surface plasmon resistance absorbance in the near‐infrared region of the electromagnetic spectrum.
