The effects of fiber silane modification on the mechanical performance of chopped basalt fiber/ABS composites

The purpose of this study was to examine the effects of silane coupling agent modifications on the mechanical performance of the basalt fiber (BF)-reinforced acrylonitrile-butadiene-styrene (ABS) composites. Three different silane coupling agents were used. The mechanical properties of the composites were determined by the tensile, flexural, impact tests, and dynamic mechanical analysis (DMA). According to the test results, the tensile strength increased with the use of (3-aminopropyl) triethoxysilane (AP) and 3-(trimethoxysilyl) propylmethacrylate (MA), while the use of (3-glycidyloxypropyl) trimethoxysilane (GP) reduced the tensile strength. All the silane modifications improved the flexural strength and modulus and the highest improvement was achieved with the use of AP. No remarkable difference was observed in impact properties with the use of silane coupling agents. The addition of BF significantly improved the elastic modulus of the ABS regardless of the modification type, while the further improvements were achieved through the use of AP and MA. In brief, AP showed the highest performance among the studied silane coupling agents due to the covalent bond formation between the amino group of AP and the nitrile group of styrene-acrylonitrile (SAN) matrix.

Synthesis of Substituted Pyrrolin-4-ones from Amino Acids in Mild Conditions via a Gold-Catalyzed Approach

The gold-catalyzed cyclization of various alpha-amino-ynone derivatives gave the corresponding pyrrolin-4-ones in high yields. Moreover, the use of gold(III) oxide as catalyst allows a moderate to total stereocontrol during the cyclization. These pyrrolin-4-ones are highly useful intermediates for the synthesis of functionalized pyrrolidines and other natural products.

A Unique Mdm2-Binding Mode of the 3-Pyrrolin-2-one- and 2-Furanone-Based Antagonists of the p53-Mdm2 Interaction

The p53 pathway is inactivated in almost all types of cancer by mutations in the p53 encoding gene or overexpression of the p53 negative regulators, Mdm2 and/or Mdmx. Restoration of the p53 function by inhibition of the p53-Mdm2/Mdmx interaction opens up a prospect for a nongenotoxic anticancer therapy. Here, we present the syntheses, activities, and crystal structures of two novel classes of Mdm2-p53 inhibitors that are based on the 3-pyrrolin-2-one and 2-furanone scaffolds. The structures of the complexes formed by these inhibitors and Mdm2 reveal the dimeric protein molecular organization that has not been observed in the small-molecule/Mdm2 complexes described until now. In particular, the 6-chloroindole group does not occupy the usual Trp-23 pocket of Mdm2 but instead is engaged in dimerization. This entirely unique binding mode of the compounds opens new possibilities for optimization of the Mdm2 p53 interaction inhibitors.

Synthesis and evaluation of the anti-proliferative activity of diaryl-3-pyrrolin-2-ones and fused analogs

Analogs containing a central 3-pyrrolin-2-one core with different methoxyphenyl and/or indole substituents were prepared and tested for anti-proliferative activity in U-937 cells. The most efficacious analogs were non-rigid, (non-fused) contained methoxyaryl groups located at the 4-position, and contained either methoxyaryl or indole groups located at the 3-position. Both the number of methoxy groups contained in the substituents and the particular location of the indole rings with respect to the lactam carbonyl had significant affects on anti-proliferative activity. This work provides a framework to better understand structure-activity relationships for inducing anti-proliferative activity in diaryl heterocyclic scaffolds. (C) 2016 Elsevier Ltd.

Synthesis and herbicidal activity of novel 3-alkoxycarbonyl-3-aryl-2, 3-dihydro-2-oxo-1H-pyrrole derivatives

In the course of efforts to find novel compounds with improved crop safety in transplanted rice by the modification of 1-[1-(3,5 -dichlorophenyl)-1-methylethyl]-4-methyl-3-phenyl-3-pyrrolin-2-one (1a), which was reported to have excellent herbicidal activity against paddy weeds, 2,3-dihydro-2-oxo-1H-pyrrole derivatives with a quaternary carbon atom having an alkoxycarbonyl group at the alpha-position of the cyclic amide were synthesized and examined. Among these compounds, methyl 1-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-4-methyl-2-oxo-3-phenyl-1H-pyrrole-3-carboxylate (2a) was not only active against Echinochloa oryzicola and Scirpus juncoides but also compatible with transplanted rice even in harsh conditions. On the bask of Preliminary experimental results. it was thought that 2a would generate the corresponding 2-oxo-3-pyrrolin (la) through the metabolic degradation of the methoxycarbonyl moiety.

Novel oxidized derivatives of antifungal pyrrolnitrin from the bacterium Burkholderia cepacia K87

The screening of antifungal active compounds from the fermentation extracts of soil-borne bacterium Burkholderia cepacia K87 afforded pyrrolnitrin (1) and two new pyrrolnitrin analogs, 3-chloro-4-(3-chloro-2-nitrophenyl)-5-methoxy-3-pyrrolin-2-one (2) and 4-chloro3-(3-chloro-2-nitrophenyl)-5-methoxy-3-pyrrolin-2-one (3). Pyrrolnitrin showed strong antifungal activity against Rhizoetonia solani but the analogs (2 and 3) were found to be marginally active. The isolates, 2 and 3, are believed to be biodegraded derivatives of pyrrolnitrin.

Nitrile-Facilitated Proton Transfer for Enhanced Oxygen Reduction by Hybrid Electrocatalysts

To enable efficient energy conversion schemes for our society in the future, breakthroughs in precise thermodynamic and kinetic control of the underlying redox reactions are necessary. Hybrid bilayer membranes (HBMs), comprising a self-assembled monolayer (SAM) covered by a lipid membrane, have been developed recently to regulate the performance of HBM-embedded electrocatalysts. A major technological roadblock in HBM development is the inability to facilitate proton transfer under alkaline conditions where nonprecious metal (NPM) catalysts can rival the performance of their precious metal counterparts. Here, we synthesized proton carriers bearing nitrile groups found in protonophores. These bioinspired proton carriers can facilitate transmembrane proton delivery to an HBM-supported Cu oxygen reduction reaction (ORR) catalyst under alkaline conditions. Our stimuli-responsive proton regulators can turn on the activity of the ORR catalyst on-demand, thereby opening doors to investigate how proton transfer kinetics govern the performance of electrocatalysts for renewable energy conversion processes.
