Molecular Docking Reveals a Novel Binding Site Model for Fentanyl at the μ-Opioid Receptor
The ligand binding modes of a series of fentanyl derivatives are examined using a combination of conformational analysis and molecular docking to the μ-opioid receptor. Condensed-phase molecular dynamics simulations are applied to evaluate potential relationships between ligand conformation and fentanyl substitution and to generate probable “bioactive” structures for the ligand series. Automate...
متن کاملEvidence of morphine like substance and μ-opioid receptor expression in Toxacara canis (Nematoda: Ascaridae)
Toxocara canis (Nematoda: Ascaridae) is an intestinal nematode parasite of dogs, which can also cause disease in humans. Transmission to humans usually occurs because of direct contact with T. canis eggs present in soil contaminated with the feces of infected dogs. This nematode has extraordinary abilities to survive for many years in different tissues of vertebrates, and deve...
متن کاملReplacement of Serine363 and Serine375 Codons by Alanine in Rat μ-Opioid Receptor cDNA
The aim of this study was to use site directed mutagenesis technique to construct a vector in which serine363 and serine375 residues of the COOH-terminal portion of the μ-opioid receptor (MOR) were substituted by alanine. These constructs are essential in studying G-protein coupled receptor kinase-mediated MOR desensiti-zation. The nested PCR carried out for conversio...
متن کاملμ-Opioid receptor desensitization: homologous or heterologous?
There is considerable controversy over whether μ-opioid receptor (MOPr) desensitization is homologous or heterologous and over the mechanisms underlying such desensitization. In different cell types MOPr desensitization has been reported to involve receptor phosphorylation by various kinases, including G-protein-coupled receptor kinases (GRKs), second messenger and other kinases as well as pert...
متن کاملLigand bias at the μ-opioid receptor.
Ligand bias refers to the ability of a drug at a receptor to activate selectively particular cell signalling pathways over others, in a way that cannot be explained by traditional models of receptor theory. For a physiologically and therapeutically important GPCR (G-protein-coupled receptor) such as the MOPr (μ-opioid receptor), the role of ligand bias is currently being explored, not only in o...
