Amador-Sanchez, Yoarhy A. published the artcileDiversity-Oriented Synthesis of Highly Fluorescent Fused Isoquinolines for Specific Subcellular Localization, Category: alcohols-buliding-blocks, the main research area is fluorescent fused isoquinoline cell.

A multicomponent diversity-oriented synthesis of new highly emissive tetracyclic isoquinolines that target specific organelles is described. The title compounds were prepared via a three-step protocol starting with an Ugi four-component reaction, followed by either an intramol. alkyne hydroarylation and subsequent alkene isomerization or through a Pomeranz-Fritsch-type cyclization with a final intramol. Heck reaction. Subcellular localization studies of these compounds using green channel confocal microscopy revealed remarkable and distinctive distribution patterns in live cells, showing an unprecedented high selectivity and imaging contrast. The differentiated organelle visualization-including localizers for mitochondria, lysosomes, Golgi apparatus, endoplasmic reticulum, and plasma membrane-was achieved by varying the nature of the tetracyclic system and substituent pattern, changing the original four-component set in the starting Ugi reaction.

Guo, Qingwen published the artcileHypoglycemic effects of polysaccharides from corn silk (Maydis stigma) and their beneficial roles via regulating the PI3K/Akt signaling pathway in L6 skeletal muscle myotubes, SDS of cas: 59-23-4, the main research area is Maydis stigma polysaccharide hypoglycemia alpha glucosidase skeletal muscle cell; Corn silk polysaccharides; Hypoglycemia; L6 myotubes; PI3K/Akt signaling pathway.

In the present study, the physicochem. properties of polysaccharides from corn silk (CSP) with different mol. weights were characterized and their inhibitory actions against α-glucosidase and α-amylase were evaluated. Then their effects on glucose uptake and mechanism of action in PI3K/Akt signaling pathway were also determined in L6 skeletal muscle cells. Results demonstrated that CSP could significantly inhibit a-amylase and a-glucosidase. CSP were non-toxic and they considerably increased the 2-NBDG uptake (P < 0.05) in L6 cells. Addnl., CSP regulated the PI3K/Akt signaling pathway and promoted the translocation of GLUT4 to the plasma membrane that would enhanced the glucose uptake in rat L6 skeletal muscle cells. Among the tested polysaccharides, CSP2 with the mol. weight of 62.16 kDa exerted appreciable hypoglycemic activity. Altogether it was suggested that CSP could be the promising candidate in the treatment of Type 2 Diabetes Mellitus (T2DM). The elucidation of the potential anti-diabetic mechanism of the polysaccharides from corn silk will facilitate their utilization in the functional food industries.

Huo, Jiaying published the artcileImmunomodulatory activity of a novel polysaccharide extracted from Huangshui on THP-1 cells through NO production and increased IL-6 and TNF-α expression, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is polysaccharide Huangshui Moringa monosaccharide Escherichia; Baijiu; Huangshui; Immunomodulatory activity; Polysaccharide; Structural characterization.

Huangshui (HS), the byproduct of Chinese Baijiu, has attracted considerable attention due to its nutrient and microbial composition; however, none of the studies has explored the polysaccharides in HS yet. Here, from HS, we isolated a novel polysaccharide, HSP-3, with an average mol. weight of 26.40 kDa. The structure was elucidated based on monosaccharide composition and methylation anal., NMR, FT-IR, and AFM anal. It is mainly composed of mannose (46.6%), galactose (17.3%), arabinose (11.2%), glucose (10.5%), xylose (8.2%), fucose (5.2%), and rhamnose (1.0%). The backbone of HSP-3 was made up of → 2-β-D-Manp-(1 → 2,6)-β-D-Manp-1 → 6-β-D-Galp-(1 → 3,6)-β-D-Galp-(1 → 4)-α-L-Rhap-1 → 3,4-α-L-Rhap-1 → . Moreover, stimulation of the production of ROS, NO, TNF-α and IL-6, upregulation of the mRNA and protein expression levels of TNF-α and IL-6 in THP-1 cells, and enhanced the pinocytic and phagocytic capacities of THP-1 cells exhibited significant immunomodulatory properties of HSP-3. Altogether, this study suggests that HSP-3 could be used as an active component in functional foods.

Pan, Mingzhang published the artcileReduction in PM and NOX of a diesel engine integrated with n-octanol fuel addition and exhaust gas recirculation, Category: alcohols-buliding-blocks, the main research area is nitrogen oxide octanol diesel engine exhaust gas particulate matter.

N-Octanol with its high energy d. and high cetane number has similar fuel properties as diesel fuel, and is thus considered an excellent choice for alc. fuels as a substitute for diesel. This study focused on the effects of exhaust gas recirculation (EGR) combined with the addition of n-octanol on the performance, emissions, and particulate matter (PM) of a direct injection diesel engine. The results show that the curves of the in-cylinder pressure of n-octanol/diesel blends nearly overlap those of pure diesel fuel under the test conditions. At a low EGR ratio, the brake thermal efficiency of n-octanol/diesel blends is higher than that of diesel fuel. With an increase in the EGR ratio, the results show that nitrogen oxide (NOX) emissions decrease, whereas carbon monoxide (CO) and soot emissions significantly increase. However, the use of n-octanol/diesel blends can inhibit the increase in CO and soot emissions appreciably. In addition, with an increase in n-octanol content in the blends, the number concentration of particles on the particle size distribution decreases gradually. To summarize, a simultaneous reduction in NOX and PM emissions under a combined operation of small EGR ratios and n-octanol blends can be realized, thereby improving the brake thermal efficiency.

Wang, Tong published the artcileHigh-Speed Countercurrent Chromatography-Based Method for Simultaneous Recovery and Separation of Natural Products from Deep Eutectic Solvent Extracts, Safety of (S)-2-hydroxysuccinic acid, the main research area is natural product separation extraction deep eutectic solvent.

The use of deep eutectic solvents (DESs) to extract natural products has attracted considerable attention in recent years. However, the recovery of extracted compounds and DES from DES extracts is still a barrier, which restricts the large-scale application of DESs. Here, we proposed a high-speed countercurrent chromatog. (HSCCC)-based method to recover extracted compounds and DES. As a proof of concept, the chrysanthemum DES extract was selected to verify the method. We first prepared a series of DES-based solvent systems and screened them based on their phys. and chem. properties. Only the system composed of choline chloride/L-malic acid, water, and Et acetate (1:1:1, volume/volume/v) was suitable. By using the solvent system for HSCCC separation, the target compounds and DES in the chrysanthemum DES extract were both successfully recovered with high recovery yields over 95%. Then, we investigated the reusability of the recovered DES and found that it could be repeatedly reused for three times without any performance deterioration. All these results indicated that the proposed method is feasible and efficient, which has great potential for application. Moreover, the method may also be used in other fields where the separation process is needed, such as organic synthesis, chem. separation, biosepn., and biotransformation. A simple and efficient method was developed for recycling deep eutectic solvents used in the natural product green extraction and separation process.

Li, Yanqing published the artcileBis(N-acylated imidazolin-2-imine) nickel catalyzed norbornene copolymerization with methyl acrylate, Product Details of C4H11NO2, the main research area is imidazolin imine catalyzed norbornene methyl acrylate copolymerization.

The incorporation of even a small number of polar functional groups in the polyolefin backbone is sufficient to improve the polyolefin properties. Compared with palladium catalyzed direct copolymerization of olefins with polar vinyl monomers, the development of low-cost nickel-based catalysts is more challenging because of their higher oxophilicity. On the basis of the advantage of reducing the electrophilicity of the nickel center by the installation of strongly electron-donating ligands, we herein report the synthesis of novel bis(N-acylated imidazolin-2-imine) nickel complexes for norbornene polymerization and copolymerization with polar monomers. Moreover, the Ph substituent on the imidazoline ligand is expected to enhance the tolerance of the nickel catalyst toward polar functional groups, thus allowing the copolymerization of norbornene with com. Me acrylate to afford high mol. weight functionalized cyclic olefin copolymers (COCs) with moderate activity and reasonable comonomer content.

Hu, Zhiqi published the artcileImproved Mechanical Durability of High-Performance OPVs Using Semi-Interpenetrating Networks, Category: alcohols-buliding-blocks, the main research area is organic photovoltaic device bending deformation mech durability.

Organic photovoltaic (OPV) devices offer a number of unique advantages over conventional single crystal silicon solar cells, such as simple and low-cost fabrication, significantly reduced weight, high flexibility, and semitransparency. However, OPV devices exhibit poor durability to mech. deformations. Here, the use of an elastic semi-interpenetrating network is studied to improve the mech. durability of the active layer of OPV devices based on the high-performance donor:acceptor blend (PBDBT-2F:ITIC). The elastic interpenetrating network is synthesized in situ through the UV photoinitiated crosslinking of thiol-ene additives in the active layer. The effects of strain as a function of bending on the network-stabilized active layer structure are systematically investigated. The elastic interpenetrating network suppresses crack formation and improves durability to high-curvature and repeated bending deformations. Performance measurements show that network-stabilized devices outperform pristine devices above a critical bending strain and number of bending deformations. The photovoltaic performance in general decreases with the increase in the network content, and the best performing devices are obtained using network forming reagents that are most compatible with the donor:acceptor system. This work describes an effective route to flexible devices using semi-interpenetrating polymer networks and provides insight into the design of the networks to maximize photovoltaic performance.

Abdelrahman, Mustafa K. published the artcileEmergent Surface Topography Enabled by Concurrent Crystallization and Polymerization, Synthetic Route of 7575-23-7, the main research area is emergent surface topog enabled concurrent crystallization polymerization.

Materials with dynamic surface topog. may enable a variety of new technologies from smart coatings to biomaterials with controlled cell-material interaction. However, current approaches to create morphing surfaces require programming procedures, either before or after polymerization, that complicate the application of these materials. Here, we exploit the metastability of the microstructure of semicrystalline polymer networks that crystallize while photopolymerizing to create polymer coatings and microstructures that irreversibly morph from smooth to rough in an emergent manner when heated. For example, a smooth polymer coating with a root-mean-square (Rq) roughness of 15 nm transforms into a rough film with a Rq roughness of 688 nm on heating through the melt temperature We show that this behavior is observed across a range of polymer networks and that the degree of undercooling during polymerization is the primary factor that controls the magnitude of roughness. This technique is not limited to polymer films; microstructures fabricated utilizing micromolding or emulsion polymerization also undergo changes in roughness on heating. Finally, we discuss using this approach to create polymer structures with spatiotemporal control of coefficients of friction and contact angles.
