Archiv der Pharmazie, Volume 356, Issue 1, January 2023., 2023 Based on a simplified version of the morphinan scaffold, 3‐[3‐(phenalkylamino)cyclohexyl]phenol analogues were designed, synthesized and evaluated for their µ‐opioid receptor (MOR) antagonist activity in vitro and in silico. Docking studies indicate a peculiar combination of C‐1 stereochemistry and N‐substitutions as feasibly essential for MOR‐ligand ...

Receptors for morphine and opioids
General Pharmacology: The Vascular System, 1976 Two points concerning enzymatic systems acting on disposal of morphine are discussed, namely the multiplicity of glucuronyltransferase and the effect of nalorphine on N-demethylation of morphine. Evidences of the presence of at least two different glucuronyltransferases in microsomes of rat liver, kidney and intestine are presented. These evidences are

Machine-learning Analysis of Opioid Use Disorder Informed by MOR, DOR, KOR, NOR and ZOR-Based Interactome Networks [PDF]
arXiv, 2023 Opioid use disorder (OUD) continuously poses major public health challenges and social implications worldwide with dramatic rise of opioid dependence leading to potential abuse. Despite that a few pharmacological agents have been approved for OUD treatment, the efficacy of said agents for OUD requires further improvement in order to provide safer and ...
