Synthesis of primary N-arylthioglyoxamides from anilines, elemental sulfur and primary C-H bonds in acetophenones

A simple method for coupling of anilines, acetophenones, and elemental sulfur to afford N-arylthioglyoxamides has been developed. Reactions proceeded in the presence of Na2SO3 and DMSO, thus eliminating the need for transition metals and external oxidants. Functionalities such as halogen, ester, methylthio, and heterocycle groups were compatible with the conditions. Electron-poor acetophenones sometimes gave isosteric glyoxamides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 85-91-6. Safety of Methyl N-Methylanthranilate.

A phase change material embedded composite consisting of kapok and hollow PET fibers for dynamic thermal comfort regulation

Kapok fiber, an agricultural product, is a typical cellulosic fiber with the features of thin cell wall and large lumen. Herein, a microtubule-based composite with high porosity of 98.03 % was prepared using kapok fibers and hollow PET. The kapok fiber-based composite successfully encapsulated a phase change material (PCM), that is a fatty acid ester of myristic acid and tetradecyl alcohol (MA-TD), in the microtubules by vacuum impregnation. The SEM showed that the PCM was encapsulated in the lumens of the fibers with a calculated percentage of 40.5 %. This condition provided the composite a basic thermal insulation from air pockets in the composite and a dynamic thermal insulation from the PCM. The kapok/PET/MA-TD could absorb 76.8 J/g latent heat in the comfort temperature range of 24 degrees C – 42.3 degrees C or release 77.4 J/g latent heat in the comfort temperature range of 29.7 degrees C – 10.5 degrees C. It withstood repeated laundry and exhibited robust leakage resistance to continuous heating/cooling under pressure. In addition, the composite was successfully used to dynamically regulate the temperature with obvious thermal regulating capacity in the simulated cooling/hot environments. Such material will be a robust candidate for dynamic heat regulating and thermal insulating applications.

Synthesis of 4-substituted-3-Hydroxyquinolin-2(1H)-ones with anticancer activity

Herein we show that the 3-hydroxyquinolin-2(1H)-one (3HQ) core is a suitable platform to develop new compounds with anticancer activity against MCF-7 (IC50 up to 4.82 mu M) and NCI-H460 (IC50 up to 1.8 mu M) cancer cell lines. The ring-expansion reaction of isatins with diazo esters catalysed by di-rhodium (II) complexes proved to be a simple and effective strategy to synthesize 4-carboxylate-3HQs (yields up to 92%). 4-Carboxamide-3HQs were more efficiently prepared using NHS-diazoacetate in yields up to 88%. This innovative methodology enabled the construction of peptidic-like 3HQs, with several amino acid substituents. Among this series, the L-leucine derivative induced the cell death of MCF-7 (IC50 of 15.1 mu M) and NCI-H460 (IC50 of 2.7 mu M) cancer cell lines without causing any appreciable cytotoxicity against the non-cancer cell model (CHOK1).

A Flexible and Self-Healable Gelled Polymer Electrolyte Based on a Dynamically Cross-Linked PVA Ionogel for High-Performance Supercapacitors

Ionogels combine the virtues of polymers and ionic liquids (ILs) and have greater potential for supercapacitors (SCs) than hydrogels and organic gels. Undoubtedly, the self-healing ability of ionogels dramatically improves the reliability of related SCs. Herein, we reported a dynamic diol-borate ester-cross-linked polyvinyl alcohol (PVA) ionogel electrolyte for smart double-layer capacitors. The results indicated that 1-ethyl-3-methylimidazolium chloride (EmimCl) could form a strong interaction with the hydroxy groups on PVA, thereby depressing the crystallization efficiently. The resultant ionogel exhibited an amorphous nature with excellent ionic conductivity up to 2.43 x 10(-3) S/cm, high flexibility, and 95% healing efficiency when the IL content was 90 vol %. It could be inferred from the fact that EmimCl acted not only as an ion provider to improve the ionic conductivity but also as a plasticizer to enhance the chain mobility and self-healing efficiency. Based on the unique properties of PVA-boric acid/EmimCl ionogels, a flexible and self-healable SC was assembled. The as-prepared SC delivered a specific capacitance of 90 F/g at 0.1 A/g and retained 98% capacitance after 3000 charge-discharge cycles at a current density of 2 A/g. More interestingly, it could tolerate physical bending and healing without significant performance deterioration. The present study provides a novel strategy to prepare self-healable ionogel electrolytes that can be applied to smart energy storage devices.

In Situ Surface Modification of Microfluidic Blood-Brain-Barriers for Improved Screening of Small Molecules and Nanoparticles

Here, we have developed and evaluated a microfluidic-based human blood-brain-barrier (mu BBB) platform that models and predicts brain tissue uptake of small molecule drugs and nanoparticles (NPs) targeting the central nervous system. By using a photocrosslinkable copolymer that was prepared from monomers containing benzophenone and N-hydroxysuccinimide ester functional groups, we were able to evenly coat and functionalize mu BBB chip channels in situ, providing a covalently attached homogenous layer of extracellular matrix proteins. This novel approach allowed the coculture of human endothelial cells, pericytes, and astrocytes and resulted in the formation of a mimic of cerebral endothelium expressing tight junction markers and efflux proteins, resembling the native BBB. The permeability coefficients of a number of compounds, including caffeine, nitrofurantoin, dextran, sucrose, glucose, and alanine, were measured on our mu BBB platform and were found to agree with reported values. In addition, we successfully visualized the receptor-mediated uptake and transcytosis of transferrin-functionalized NPs. The BBB-penetrating NPs were able to target glioma cells cultured in 3D in the brain compartment of our mu BBB. In conclusion, our /BBB was able to accurately predict the BBB permeability of both small molecule pharmaceuticals and nanovectors and allowed time-resolved visualization of transcytosis. Our versatile chip design accommodates different brain disease models and is expected to be exploited in further BBB studies, aiming at replacing animal experiments.

NiCoO2@CeO2 Nanoboxes for Ultrasensitive Electrochemical Immunosensing Based on the Oxygen Evolution Reaction in a Neutral Medium: Application for Interleukin-6 Detection

The development of highly active electrocatalytic labels is important for constructing sensitive electrochemical immunosensors. Great progress has been made in developing non-noble-metal nanocatalysts toward the oxygen evolution reaction (OER) in the past decade, but non-noble-metal OER nanocatalysts have not been explored as electrocatalytic labels for immunosensing. Herein, we report NiCoO2@CeO2 nanoboxes (NBs) as novel electrocatalytic labels for ultrasensitive immunosensing based on the excellent OER activity of NiCoO2@CeO2 NBs in a neutral solution. The synthesis of NiCoO2@CeO2 NBs involves Ni2+ exchange and heat treatment of ZIF-67 nanocubes to produce NiCoO2 NBs, followed by the growth of CeO2 nanoparticles on the surface of NiCoO2 NBs. The NiCoO2@CeO2 NBs offer superior OER activity to NiCoO2 NBs because of the synergetic effect between NiCoO2 NBs and CeO2 nanoparticles. The formation of ester-like bridging between CeO2 and the carboxylic groups of antibody enables direct immobilization of the antibody on the NiCoO2@CeO2 surface. A sandwich-type electrochemical immunosensor using NiCoO2@CeO2 NBs as electrocatalytic labels features a broad linear range for interleukin-6 detection from 2.5 x 10(-5) to 10 ng mL(-1), with a low detection limit of 7 fg mL(-1). Our work lays the foundation for developing electrochemical immunosensors and aptasensors based on non-noble-metal OER electrocatalysts.

The Effects of Prodrug Size and a Carbonyl Linker on l-Type Amino Acid Transporter 1-Targeted Cellular and Brain Uptake

The l-type amino acid transporter 1 (LAT1, SLC7A5) imports dietary amino acids and amino acid drugs (e. g., l-DOPA) into the brain, and plays a role in cancer metabolism. Though there have been numerous reports of LAT1-targeted amino acid-drug conjugates (prodrugs), identifying the structural determinants to enhance substrate activity has been challenging. In this work, we investigated the position and orientation of a carbonyl group in linking hydrophobic moieties including the anti-inflammatory drug ketoprofen to l-tyrosine and l-phenylalanine. We found that esters of meta-carboxyl l-phenylalanine had better LAT1 transport rates than the corresponding acylated l-tyrosine analogues. However, as the size of the hydrophobic moiety increased, we observed a decrease in LAT1 transport rate with a concomitant increase in potency of inhibition. Our results have important implications for designing amino acid prodrugs that target LAT1 at the blood-brain barrier or on cancer cells.
