In silico study, synthesis, and evaluation of the antimalarial activity of hybrid dimethoxy pyrazole 1,3,5-triazine derivatives

Malaria continues to become a major global health problem, particularly in Sub-Saharan Africa, Asia, and Latin America. The widespread emergence of resistance to first-line drugs has further bolstered an urgent need for a new and cost-effective antimalarial(s). Thus, the present study enumerates the synthesis of novel hybrid dimethoxy pyrazole 1,3,5-triazine derivatives 7(a-j) and their in silico results short-listed three compounds with good binding energies and dock scores. Docking analysis shows that hydrogen-bonding predominates and typically involves key residues, such as Asp54, Tyr170, Ile164, and Arg122. The in vitro antimalarial evaluation of three top-ranked compounds (7e, 7g, and 7h) showed half-maximal inhibitory concentration values range from 53.85 to 100 mu g/ml against chloroquine-sensitive strain 3D7 of Plasmodium falciparum. Compound 7e may be utilized as a lead for further optimization work in drug discovery due to good antimalarial activity.

An NIR-II light responsive antibacterial gelation for repetitious photothermal/thermodynamic synergistic therapy

Drug-resistant bacterial infection is a serious threat to the survival and health of human. Clinically, the conventional therapy for subcutaneous infections generally involves the systemic administration of high dose of antibiotics and frequently causes detrimental side effects in normal tissues. To overcome this issue, an acidity-responsive near infrared (NIR) light-triggered injectable hydrogel was designed for non-antibiotic local treatment. Herein, poly(ethylene glycol) diacrylate (PEGDA) was used as hydrogel matrix, polyoxometalate (POM) as acidity-enhanced photothermal agent and 2,2′-azobis[2-(2-imidazolin-2-yl) propane] dihydro-chloride (AIPH) as thermo-responsive initiator. After the hydrogel precursor solution (AIPH/POM/PEGDA) was injected into the acidic infected tissue, the aggregated POM with strong photothermal property was restricted to the site of abscess. Upon excitation at 1060 nm laser, the heat generated from POM would trigger alkyl radical formation from AIPH and thereafter achieving NIR-triggered in situ gel. Consequently, the POM and AIPH were trapped in Gel (AIPH/POM) and exhibited long-term retention in the abscess for further repeated local photothermal/thermodynamic antibacterial therapy. In vitro antibacterial evaluation indicated that the system could effectively eradicate drug-resistant bacteria through destroying bacteria integrity and producing the noxious alkyl radical under NIR light illumination. Moreover, the bacterial burden of abscess was significantly relieved and more collagens were deposited after the administration of Gel(AIPH/POM) and repeated NIR light. Meanwhile, no apparent adverse effect was observed during the treatment. This work not only provides a light-triggered gelation for local photothermal/thermodynamic synergistic therapy, but also offers a novel strategy for the rational design of light-responsive intelligent antibacterial hydrogels.

Synthesis of N-(3-aminopropyl)imidazole-based poly(ionic liquid) as an adsorbent for the selective recovery of Au(iii) ions from aqueous solutions

The synthesis of a novel poly(ionic liquid) adsorbent (PIL-APIBCl) through the modification of poly(styrene-co-maleic anhydride) (PSMA) composites with N-(3-aminopropyl)imidazole (API) and benzyl chloride (BCl) is presented. The structural analysis was carried out by nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and Fourier transform infrared (FT-IR). Batch adsorption experiments revealed that the investigated adsorbent exhibited good selectivity and a high adsorption capacity of 236.68 mg g(-1) towards tetrachloroaurate (Au(iii)) ions at pH 1.0 over a wide temperature range. The adsorption isotherms and kinetics of Au(iii) on the PIL-APIBCl were fitted well by the Langmuir isotherm model and pseudo-second-order model, respectively, indicating successful chemical adsorption of Au(iii) ions on the adsorbent surfaces. According to FESEM, FT-IR, XPS and NMR analysis, the adsorption mechanisms of Au(iii) on PIL-APIBCl could be ascribed to electrostatic and intermolecular interactions. Therefore, due to its good cyclability and low cost, PIL-APIBCl is a promising adsorbent for Au(iii) recovery from wastewater on a large scale.

Effect of aging treatment on microstructure and corrosion behavior of Al-Zn-Mg aluminum alloy in aqueous solutions with different aggressive ions

The microstructure and corrosion behavior of Al-Zn-Mg alloy (namely 7xxx) after natural aging treatment (NAT) and artificial aging treatment (AAT) in aqueous NaCl solutions containing different aggressive ions have been investigated in current work. Results of microstructure characterization demonstrate that the aging treatment has a great influence on the grain size and precipitates. The grain size is relatively sizeable and no evident precipitates are observed in alloy after NAT comparable with that after AAT. The electrochemical corrosion behavior of alloy was studied by polarization curve and electrochemical impedance spectroscopy (EIS). The corrosion potential (Ecorr) of the aluminum alloy is more negative in 3.5 wt.% NaCl containing 0.052 wt.% NaHSO3 solution than that in 3.5 wt.% NaCl solutions with or without 0.907 wt.% NaHCO3. Charge transfer resistance (Rct) results reveal that alloy after AAT has an enhancement of corrosion resistance compare with that after NAT. With the immersion time increasing, mostly pitting spreads over the surface of the alloy only in NaCl solution, whereas exfoliation corrosion mainly occurs in NaCl solutions containing NaHSO3 or NaHCO3.

Biomimetic superhydrophobic membrane with multi-scale porous microstructure for waterproof and breathable application

The multifunctional membranes with superior waterproofness and breathability have been extensively used in high-end wearable protection, desalination, and the aerospace industry. A multi-layered, biomimetic and superhydmphobic membrane is designed via a facile two-step strategy of phase-conversion and electrospraying. The homogeneous reticular porous microstructure with a stellate spherulite surface formed by introducing sodium chloride (NaCl) during the phase-conversion process provides an effective vapor-permeable channel for the membrane. Zirconium carbide (ZrC)/silica (SiO2) as two-component inorganic powders with different particle sizes can construct bio-inspired, hierarchical, and superhydrophobic layers. Simultaneously, the synergistic interactions between the components can preferably inspire the photo-to-thermal conversion properties of membranes, further accelerating the efficient transport of water vapor. The ultrathin hierarchical nanoporous composite membrane exhibits the excellent breathability of 11.9 kg m(-2) d(-1) and decent waterproofness of 60.71 kPa. An ultrahigh WCA of up to 167.3 degrees gives a stabilized superhydrophobic surface to the high moisture-permeable membrane while possessed robust reusable self-cleaning and photo-to-thermal properties. Furthermore, the superior performances with the tremendous potential for application prospects in various fields.

Promotive role of microRNA-150 in hippocampal neurons apoptosis in vascular dementia model rats

Cognitive impairment is one of the primary features of vascular dementia (VD). However, the specific mechanism underlying the regulation of cognition function in VD is not completely understood. The present study aimed to explore the effects of microRNA (miR)-150 on VD. To determine the effects of miR-150 on cognitive function and hippocampal neurons in VD model rats, rats were subjected to intracerebroventricular injections of miR-150 antagomiR. The Morris water maze test results demonstrated that spatial learning ability was impaired in VD model rats compared with control rats. Moreover, compared with antagomiR negative control (NC), miR-150 antagomiR alleviated cognitive impairment and enhanced memory ability in VD model rats. The triphenyltetrazolium chloride, Nissl staining and immunohistochemistry results further demonstrated that miR-150 knockdown improved the activity of hippocampal neurons in VD model rats compared with the antagomiR NC group. To validate the role of miR-150 in neurons in vitro, the PC12 cell line was used. The flow cytometry and Hoechst 33342/PI double staining results indicated that miR-150 overexpression significantly increased cell apoptosis compared with the mimic NC group. Moreover, the dual-luciferase reporter gene assay results indicated that miR-150 targeted HOXA1 and negatively regulated HOXA1 expression. Therefore, the present study indicated that miR-150 knockdown ameliorated VD symptoms by upregulating HOXA1 expression in vivo and in vitro.

A Zn-Ce Redox Flow Battery with Ethaline Deep Eutectic Solvent

Compared with conventional aqueous and ionic liquid electrolytes, deep eutectic solvent (DES) are considered as electrolyte for redox flow batteries because they have a wider electrochemical window and relatively low price. In this study, Ce-IV/Ce-III and Zn-II/Zn redox couples are used as the positive and negative active materials, respectively, in an electrolyte consisting of choline chloride ethylene glycol (ethaline). The structure of Ce-III in the positive electrolyte is inferred through spectrum detection. Ce-IV/Ce-III and Zn-II/Zn redox couples show a stable potential difference of 2.2 V (vs. Ag) through cyclic voltammetry. The charge and discharge performance of battery was tested at different current densities. In addition, battery performance was evaluated at different temperatures and concentrations of cerium in the electrolyte. Consequently, at a current density of 0.5 mA cm(-2) at room temperature and using 1.0 m Ce-III, the battery performance reaches the best coulombic efficiency of 84 %.

Ni-Mo-Cr alloy corrosion in molten NaCl-KCl-MgCl2 salt and vapour

The corrosion behaviours of Ni-Mo-Cr alloy samples immersed in NaCl-KCl-MgCl2 salt and vapour were investigated at 700.0 degrees C for 100 h. The surface layer of the corroded alloy in liquid molten salt exhibited slight Cr depletion. The alloy formed a loose double layer of Cr, Mo and Mg oxide in the vapour. The oxidation with Mg chloride in the salt vapour accelerated corrosion of the sample, and its Cr-depleted depth was nearly twice that of a sample immersed in liquid molten salt. The corrosion of an alloy by salt vapour must not be neglected in practical applications.

Paper-Based Enzyme Biosensor for One-Step Detection of Hypoxanthine in Fresh and Degraded Fish

Food freshness monitoring, which can reflect the quality of the product at the time of use, remains a great challenge for consumers and the food industry. Herein, we report the development of a cost-effective enzyme-based paper biosensor, which can monitor fish freshness and predict spoilage. The biosensor measures the release of hypoxanthine (HX), an indicator of meat and fish degradation, using the enzymatic conversion of HX by xanthine oxidase (XOD). We demonstrate that the entrapment of XOD and an organic dye, nitro blue tetrazolium chloride (NBT), within a sol-gel biohybrid enables their stabilization on paper and promotes the enzymatic reaction with further retention of the reaction products within the cellulosic network . Linearity in the micromolar concentration range with a detection limit of 3.7 mu M for HX is obtained. The biosensor has high selectivity toward HX and is manufactured in few steps from inexpensive widely available materials. The applicability of the biosensor is demonstrated by following fish degradation over time and measuring HX concentrations ranging from 117 (+/- 9) to 198 (+/- 5) mu M within 24 h of degradation, at levels that are comparable with those measured by a commercial enzymatic kit for HX detection. As compared to the commercial kit, our biosensors are more cost-effective, do not require addition of exogenous reagents and are portable, having all of the reagents needed for analysis embedded within the sensing platform. This proof-of-concept work demonstrates that the paper-based HX biosensor has potential as a robust reagentless device for real-time monitoring of food freshness and for other applications in which HX plays an important role.
