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

open access: yesBritish 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,

(4aR*,8aS*)-2,3-Diphenyl-4a,5,6,7,8,8a-hexahydroquinoxaline

open access: yesActa Crystallographica Section E, 2012
In the title compound, C20H20N2, the quinoxaline ring adopts a very distorted half-chair conformation [N=C—C=N = 22.7 (2)° for the nominally coplanar atoms] and the cyclohexane ring adopts a chair conformation.

Acetylene terminated matrix resins [PDF]

open access: yes, 1985
The synthesis of resins with terminal acetylene groups has provided a promising technology to yield high performance structural materials. Because these resins cure through an addition reaction, no volatile by-products are produced during the processing.

A Comparative Analysis of Maillard‐Derived α‐Dicarbonyl Compounds and Advanced Glycation End Products in Fresh, Wet, Kibble, and Freeze‐Dried Dog Foods

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Thermal processing of pet foods can lead to the formation of harmful Maillard reaction products (MRPs), which may compromise nutritional quality and pose health risks to companion animals. This study compared the levels of MRPs in 41 commercial dog foods, including fresh (n = 15), kibble (n = 13), wet (n = 10), freeze‐dried (n = 2), and cold ...

Polyphenylquinoxalines via Aromatic Nucleophilic Displacement [PDF]

open access: yes
Polyphenylquinoxalines are produced by an aromatic nucleophilic displacement reaction involving an activated aromatic dihalide with an appropriate quinoxaline monomer. Polyphenylquinoxalines are high temperature thermoplastics used as adhesives, coatings,

Antitumor studies. Part 4: Design, synthesis, antitumor activity, and molecular docking study of novel 2-substituted 2-deoxoflavin-5-oxides, 2-deoxoalloxazine-5-oxides, and their 5-deaza analogs [PDF]

open access: yes, 2008
Various novel 10-alkyl-2-deoxo-2-methylthioflavin-5-oxides and their 2-alkylamino derivatives were prepared by facile nitrosative cyclization of 6-(N-alkylanilino)-2-methylthiopyrimidin-4(3H)-ones followed by nucleophilic replacement of the 2-methylthio ...

Silyl Rearrangements in Gold‐Catalyzed Transformations

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 15, 22 April 2026.
The synergy between the exceptional ability of gold catalysts to activate unsaturated substrates and the inherent tendency of organosilicon reagents to undergo silyl‐group rearrangements has unlocked a range of novel transformations, enabling access to otherwise challenging molecular architectures.
