Preparation of a boronate-affinity monolithic column for adsorption of nucleosides

Chitosan is a considerably versatile and promising biomaterial and can easily form a 3D hierarchical porous scaffold. In this work, a novel boronate-affinity monolithic column modified with a boronic acid-chitosan complex was prepared and characterized by different methods such as Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analysis, specific surface area analysis and pore size distribution analysis. The synthesized monolithic column was used for polymer monolithic microextraction combined with high performance liquid chromatography for the simultaneous determination of cytidine, uridine, inosine, and guanosine in milk powder samples. Several parameters affecting extraction efficiency, including the eluent proportion, eluent flow rate, sample flow rate, sample volume, and sample pH were investigated. The boronate-affinity monolithic column showed high enrichment ability due to the selective formation of cyclic borate esters between nucleosides and boronic acid groups at high pH and the release of cyclic borates at low pH values. Under the optimum operating conditions, the linear range was 0.1-50 mu g mL(-1), and the correlation coefficients were in the range of 0.9993-0.9994. The LOD and LOQ were in the range of 0.0027-0.0034 and 0.0090-0.011 mu g mL(-1), respectively. In addition, the results of recovery and relative standard deviation were satisfactory.

Enantioselective Copper-Catalyzed [3+3] Cycloaddition of Tertiary Propargylic Esters with 1H-Pyrazol-5(4H)-ones toward Optically Active Spirooxindoles

A copper-catalyzed enantioselective [3 + 3] cycloaddition of 3-ethynyl-2-oxoindolin-3-yl acetates with 1H-pyrazol-5(4H)-ones for the construction of optically active spirooxindoles bearing a spiro all-carbon quaternary stereocenter has been realized. With a combination of Cu(OTf)(2) and chiral tridentate ketimine P,N,N-ligand as the catalyst, the reaction displayed broad substrate scopes, good yields, and high enantioselectivities. This represents the first catalytic asymmetric propargylic cycloaddition with tertiary propargylic esters as the bis-electrophiles for access to chiral spirocyclic frameworks.

Effect of split fuel injection strategies on the diverse characteristics of CRDI diesel engine operated with tamarind biodiesel

The demand for petroleum fuels has been rapidly increasing owing to the wide use of automobiles and other agricultural engines which prefer diesel as a major fossil fuel. This research work investigates the effect of change in the fuel injection strategies on CRDI engine under various loads with tamarind seed methyl ester (TSME) 20% biodiesel blend. Initially, the diesel fuel is injected at 600 bar with 30% pilot injection (P.I) and 100% main injection (M.I). Later, TSME20 is injected at the same pressure with the two injection strategies mentioned. This study discloses that the BTE has boosted by 4.79% with 30% pilot injection than 100% main injection for the tested biodiesel. Further, TSME20 biodiesel at 30% pilot injection has shown significant reduction of hydrocarbons by 12.16%, carbon monoxide by 32.14% and smoke emissions by 19.71% when compared with 100% diesel main injection at peak load conditions. However, the pilot injection for the tested fuels has exposed slight enhancement in NOX emissions, which may be reduced by exhaust gas recirculation (EGR). Hence, the use of 30% pilot injection of TSME20 biodiesel is recommended for diesel engines as an alternative fuel which has improved performance along with reduced emissions.

Corrosion-Resistant Cross-Linked Cyanate Ester Coatings Doped by Graphene Oxide for Use in High-Temperature Marine Environments

Organic coatings are widely used to protect metals from corrosion in high-temperature marine environments. Compared with inorganic or metal coatings, organic coatings exhibit favorable properties, such as a reasonable cost, adequate flexibility, and easy fabrication. However, most organic coatings are limited to relatively short protection times and thus fail to meet the increasing demands for industrial applications. In this paper, graphene oxide (GO) was added to cyanate ester (CE) coatings as a corrosion inhibitive filler. Electrochemical analysis shows that a 3 wt % GO/CE coating has favorable corrosion protection properties with a low-frequency resistance higher than 10(6) Omega cm(2) and a corrosion rate of 632.9 x 10(-6) mm per year after 1320 h of immersion in a high-temperature marine environment. Top-view and cross-sectional SEM images identify the electrochemical results. Furthermore, chemical analyses by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy demonstrate that hydroxyl groups of GO can react with cyanate groups, and therefore, a robust cross-linked structure was formed in the GO/CE coating. The synergistic effect of the physical shielding of GO and the robust cross-linked structure makes the GO/CE coating a promising choice for corrosion protection of steel in high-temperature marine environments. Our study also illustrates a novel method for preparing other chemically cross-linked composite coatings.

Antifungal properties of natural products from Pterocarya tonkinensis against phytopathogenic fungi

BACKGROUND In the search for new natural resources showing antifungal activity, we found that the methanol extract of Pterocarya tonkinensis (Fr.) Dode suppressed the disease development caused by fungi. The objectives of this article were (i) to isolate and identify the antifungal substances from the Pterocarya tonkinensis extract based on a bioassay-guided fractionation and (ii) to investigate their potential as a biocontrol agent with their antifungal activities in vitro and in vivo. RESULTS Eighteen compounds were identified from the methanol extract of Pterocarya tonkinensis, including two new natural products 1 and 2: 1, pterocaryalactone; 2, pterocaryafuranone; 3, (1S, 6R)-9-hydroxymegastigm-7-en-3-one; 4, (S)-dimethyl malate; 5, alpha-linolenic acid; 6-8, alpha-tetralones; 9, (R)-methyl-2-hydroxyl-3-phenyl-propanoate; 10, (E)-4-hydroxycinnamic acid methyl ester; 11-14, diarylheptanoids, and 15-18, pentacyclic triterpenoids. Based on the results of the in vitro antifungal assay, Magnaporthe oryzae and Phytophthora infestans were the most sensitive to the isolated compounds among the tested phytopathogenic fungi. When ten active compounds were applied onto plants at a concentration of 100 or 500 mu g mL(-1), compounds 1 and 8 effectively suppressed rice blast disease, and compounds 15 and 16 not only strongly reduced the development of blast on rice but also effectively controlled the development of late blight on tomatoes. CONCLUSION This is the first report to evaluate the in vitro and in vivo antifungal activities of the isolated compounds from a methanol extract of Pterocarya tonkinensis against phytopathogenic fungi, and our results suggest that Pterocarya tonkinensis and its substances can be used as a source to develop natural fungicides.

Improving Oxidative Stability and Sensory Properties of Ale Beer by Enrichment with Dried Red Raspberries (Rubus idaeus L.)

Red raspberry has attracted great interest due to its inherent antioxidant, anticarcinogenic, and antihyperglycemic effects. To brew a beverage with high antioxidant capacity and desirable sensory characteristics (malty aroma, hop aroma, fruit flavor, freshness, fullness, sweetness, sourness, and bitterness), dried red raspberries (Rubus idaeus L.) (30 g L-1 wort) were added to beer at different stages of the brewing process (beginning of boiling, before fermentation, before conditioning) and compared to a control without added dried fruits. The beer was fermented with Saccharomyces cerevisiae for 7 days at 18 degrees C followed by a secondary fermentation of 3 days at 20 degrees C. The main physicochemical attributes (original gravity, ethanol content, pH, color, colloidal haze, viscosity, bitterness, diacetyl, acetaldehyde, higher alcohols, and esters), sensory characteristics, and major bioactive compounds were determined. A decline in pH and an increase in color were observed in the raspberry beers. Adding dried fruits at the beginning of boiling imparted the highest oxidative stability and total phenolic and flavonoid content (696 mg GAE L-1 and 510 mg QE L-1, respectively). Sensory analysis revealed that the most preferred product according to appearance, flavor, and taste was the beer with dried fruits added at the beginning of boiling.

Catalytic Asymmetric Mannich-Type Reaction Enabled by Efficient Dienolization of alpha,beta-Unsaturated Pyrazoleamides dagger

Main observation and conclusion (E)-alpha,beta-Unsaturated pyrazoleamides undergo facile dienolization to furnish copper(I)-(1Z,3Z)-dienolates as the major in the presence of a copper(I)-(R)-DTBM-SEGPHOS catalyst and Et3N, which react with aldimines to afford syn-vinylogous products as the major diastereoisomers in high regio- and enantioselectivities. In some cases, the diastereoselectivity is low, possibly due to the low ratio of copper(I)-(1Z,3Z)-dienolates to copper(I)-(1Z,3E)-dienolates. (Z)-Allylcopper(I) species is proposed as effective intermediates, which may form an equilibrium with copper(I)-(1Z,3Z)-dienolates. Interestingly, the present methodology is a nice complement to our previous report, in which (E)-beta,gamma-unsaturated pyrazoleamides were employed as the prenucleophiles in the copper(I)-catalyzed asymmetric vinylogous Mannich-Type reaction and anti-vinylogous products were obtained. In the previous reaction, copper(I)- (1Z,3E)-dienolates were generated through alpha-deprotonation, which might form an equilibrium with (E)-allylcopper(I) species. Therefore, it is realized in the presence of a copper(I) catalyst that (E)-alpha,beta-unsaturated pyrazoleamides lead to syn-products and (E)-beta,gamma-unsaturated pyrazoleamides lead to anti-products. Finally, by use of (E)-beta,gamma-unsaturated pyrazoleamide, (E)-alpha,beta-unsaturated pyrazoleamide, (R)-DTBM-SEGPHOS, and (S)-DTBM-SEGPHOS, the stereodivergent synthesis of all four stereoisomers is successfully carried out. Then by following a three-step reaction sequence, all four stereoisomers of N-Boc-2-Ph-3-Me-piperidine are synthesized in good yields, which potentially serve as common structure units in pharmaceutically active compounds.

Versatile, Multifunctional Block Copolymers for the Self-Assembly of Well-Defined, Nontoxic pDNA Polyplexes

In the field of systemically applied, nucleic acid-based drugs, polyplexes are interesting candidates for therapeutic systems. In this study, we synthesized a multifunctional triblock copolymer via reversible addition-fragmentation chain transfer (RAFT) block copolymerization. Due to three orthogonal reactive functionalities (an azide end group, a reactive disulfide block (P(PDSM)), and a reactive ester block (P(PFPMA))), the synthesized polymer system is highly adaptable and can be modified in a tailor-made fashion. After modification with N,N-dimethyl ethylendiamine (DMEDA), the synthesized cationic triblock copolymers form polyplexes with pDNA, even at low N/P ratios. The polyplexes can be stabilized further by cross-linking, having a size range of 113-151 nm in 10 mM NaCl, with high uniformity and low size distribution. measurements indicate a good shielding of the charged polyplex core. Additionally, no significant cytotoxicity of the polyplexes is found. First transfection experiments are positive, but the gene transfer efficiency needs to be improved further. Because of its high modifiability, the presented triblock copolymer system is a good candidate for an adjustable pDNA transport system.

Phosphorus-Containing C12H27O4P as Functional Electrolyte Additives for High-Voltage LiNi0.5Mn1.5O4/Graphite Li-Ion Batteries with Excellent Electrochemical Performance

As the most promising cathode material in new energy resources, LiNi0.5Mn1.5O4 (LNMO) are widely researched due to its high platform, low cost, and environment-friendliness, when they are assembled with graphite into battery which can lead to a faster capacity decay because of unstable solid-liquid interface. This work is devoted to stabilize electrolyte and protect interface of LNMO/graphite full battery by adding multifunctional additive, tributyl phosphate (TBP). Theory calculation which exhibits disconnection of TBP can participate in the reaction to form a uniform and dense cathode electrolyte interface film (8-10 nm) and solid electrolyte interface film around 15 nm on both electrodes, more importantly, the existence of phosphoric acid functional group can hinder the attack of hydrofluoric acid and protect electrode film. Besides, comparing with its homolog, the high-voltage LiNi0.5Mn1.5O4/graphite battery with 1% TBP shows a preponderant discharged capacity retention of 77.8% after 150 cycles, while the blank is only 66%, this work provides a direction for electrolyte additives’ selection at high voltage and has far-reaching significance for the application of phosphate ester materials.

Heteroleptic beta-Ketoiminate Magnesium Catalysts for the Ring- Opening Polymerization of Lactide

A series of heteroleptic beta-ketoimine magnesium complexes (LL)-L-1′(1) Mg2Cp*(1), (L2Mg2Cp2)-Mg-2 (2), (L2Mg2)-Mg-1(OAr)(2) (3 and 4), and (L2Mg2)-Mg-2(OAr)(2) (5 and 6) (L'(1) = Me2NC2H4NC(Me)CHC(Me)O, L-‘1 = Me2NC2H4NC(CH2)CHC(Me)O, L-2 = Me2NC3H6NC(Me)CHC(Me)O; Ar = Ph and 2,6-t-Bu-2-C6H3) with different steric and electronic properties were synthesized. 1 and 3-6 adopt binuclear structures in the solid state and in solution, whereas 2 forms a monomer/dimer equilibrium in solution. Complexes 1 and 2 showed very poor activity in the ring-opening polymerization (ROP) of racemic-lactide (rac-LA), whereas heteroleptic phenoxide complexes 3-6 are active polymerization catalysts at variable temperature in solution in the absence of any co-initiator, yielding isotactic-enriched polylactide (PLA). The catalytic activity and stereoselectivity is controlled by the electronic and steric properties of the phenoxide substituent and reaction temperature. Kinetic studies with catalyst 3 and 5 proved the first-order dependence on monomer concentration, and mechanistic studies showed that the polymerization reactions follow the coordination insertion mechanism (CIM).
