To develop efficient electrochemical energy storage systems for large-scale use of renewable energy, a novel quinoxaline-bearing redox-active conjugated polymer (poly(6-(1H-pyrrol-1-yl)quinoxaline), PPyQX) has been synthesized via a facile bromine oxidation polymerization approach and employed as electro-active anode material for aqueous hybrid flow batteries. The PPyQX displays a quasi-reversible redox reaction at ?0.79 V vs the standard hydrogen electrode (SHE) with good stability in aqueous alkaline electrolytes. An aqueous hybrid flow battery is fabricated using the PPyQX as the anode material and K4Fe(CN)6 as the catholyte, respectively, which displays an open circuit potential of 1.15 V at 50% state of charge (SOC) and a discharge capacity of 67.1 mAh g?1 at the current density of 1 A g?1. The maximum power density reaches 2.7 and 1.5 W g?1 at 100% and 50% SOC, respectively. After 1000 charge-discharge cycles, ca. 74.8% of initial discharge capacity is retained, projecting an average capacity retention rate of ~99.975% per cycle. The coulombic efficiency is near to 93.8% and the round-trip energy efficiency is kept around 80.5%.

New (E)-3-(2-aminoquinoxalin-3-yl)-1-arylprop-2-en-1-ones are prepared through the multi-component reaction of 3-substituted-2-chloroqunoxalines, calcium carbide, and aromatic aldehydes in the presence of diethylamine, catalyzed by Pd/Cu in acetonitrile. This synthetic strategy presents an acetylene molecule linking the quinoxaline scaffold to an aldehyde moiety for construction of quinoxaline chalcone by two carbon-carbon bond coupling reactions. This one-pot process provides an efficient and direct method for the synthesis of new quinoxaline chalcones from the low-cost calcium carbide with good yields. A number of synthesized compounds were screened for their in vitro anti-bacterial activity against Gram-positive and Gram-negative bacteria using a well-diffusion method.

The preclinical characterization of novel octahydropyrrolo[3,4-c]pyrroles that are potent and selective orexin-2 antagonists is described. Optimization of physicochemical and DMPK properties led to the discovery of compounds with tissue distribution and duration of action suitable for evaluation in the treatment of primary insomnia. These selective orexin-2 antagonists are proven to promote sleep in rats, and this work ultimately led to the identification of a compound that progressed into human clinical trials for the treatment of primary insomnia.

As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world.6640-47-7, Name is Quinoxaline-2,3-diamine, molecular formula is C8H8N4.

Nucleophilic aromatic substitution (SNAr) is a class of reaction that has become very important over time. This type of transformation usually proceeds without the use of metal catalysts, making it very important for pharmaceutical and industrial purposes. Nevertheless, in order to obtain the desired substituted product, activated substrates are required to allow SNAr reactions under mild conditions. In this context, quinoxaline derivatives are one class of N-heteroarenes that has attracted great attention from the scientific community because of the large variety of applications for their derivatives in many fields, such as biological and technological areas. There are several reported methods for the synthesis of quinoxaline derivatives. Nonetheless, reactions of 2,3-dichloroquinoxaline (DCQX) with nucleophilic species has become a viable alternative because of the possibility to form new carbon-heteroatom bonds (e.g. C[sbnd]O, C[sbnd]N, and C[sbnd]S) directly at C2 and/or C3 positions of the quinoxaline moiety. This current review brings an overview of the last decade on the remarkable versatility of DCQX as a substrate for SNAr reactions. Herein, we show several examples in which DCQX reacts with N-, O-, S-, P- and C-nucleophiles, including controlled processes for the selective formation of mono- and disubstituted substrates. Almost all polyfunctionalized quinoxalines synthesized using this approach have shown applications in different areas such as in biological and technological fields.
