A comprehensive approach utilizing quantum machine learning in the study of corrosion inhibition on quinoxaline compounds

Artificial Intelligence Chemistry
In this investigation, a quantitative structure-property relationship (QSPR) model coupled with a quantum neural network (QNN) was used to explore the corrosion inhibition efficiency (CIE) of quinoxaline compounds. Integrating quantum chemical properties

Steroidal quinoxalines

Journal of Heterocyclic Chemistry, 1973
AbstractThe treatment of 3β‐hydroxy‐16α‐bromo‐5α‐androstan‐17‐one, 3β‐acetoxy‐16α‐bromo‐5‐androsten‐17‐one and 21‐bromo‐5‐pregnen‐3β‐ol‐20‐one with 4,5‐dimethyl‐o‐phenylenediamine gave substituted quinoxalines.Hydrolysis of 3β‐acetoxy‐5‐androsteno[16,17‐b]‐6′,7′‐dimethylquinoxaline produced the corresponding 3β‐hydroxy compound.

Comparative Analysis of Intermediate and Advanced Maillard Reaction Products in Three Types of Commercial Edible Mushroom Products

Food Frontiers, EarlyView.
ABSTRACT In recent years, rising consumption of mushroom‐based foods has highlighted concerns over the formation of harmful Maillard reaction products (HMRPs) during thermal processing. However, limited information is available on the occurrence of intermediate and advanced HMRPs, such as α‐dicarbonyl compounds (α‐DCs) and advanced glycation end ...

Blue‐hazard‐free single‐emissive‐layer white organic LEDs based on an anti‐quenching narrowband blue emitter

FlexMat, EarlyView.
A blue‐hazard‐free single‐emissive‐layer white OLED is realized using an anti‐quenching multiple‐resonance TADF emitter, BNCT. By integrating a sterically protected MR core with efficient energy transfer capability, BNCT enables warm‐white emission with high efficiency, negligible hazardous blue photons, and a simplified device architecture for next ...

Synthesis of Some Phenylpyrazolo Benzimidazolo Quinoxaline Derivatives as Potent Antihistaminic Agents

E-Journal of Chemistry, 2010
2,3-Diphenyl quinoxaline (NI) was fused with benzimidazole (NII) by a methylene bridge, which was then allowed for acetylation. The acetylated product (NIV) was made to react with different aromatic aldehydes to give chalcones (NV1-NV5).

Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

The synthesis of imidazo[4',5':5,6]cycloocta[1,2-B]quinoxaline-2-ones and a – thione

Bulletin of the Chemical Society of Ethiopia, 2013
At present study, we synthesized the imidazo[4',5':5,6]cycloocta[1,2-b]quinoxaline-2-ones (-2-thione) with an additional double bond in the eight-membered ring via the reaction of a quinoxaline-fused cyclooctane-1,2-dione with urea (or thiourea) and N,N'-

Evidence that 5‐HT2A receptor signalling efficacy and not biased agonism differentiates serotonergic psychedelic from non‐psychedelic drugs

British Journal of Pharmacology, EarlyView.
Background and Purpose Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5‐HT2A receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5‐HT2A receptor ligand bias or signalling efficacy. Here,
