    • The 5-HT1E receptor. Receptor structure and ligand interactions. 

      Gabrielsen, Mari (Master thesis; Mastergradsoppgave, 2006-12-08)
      5-HT (5-Hydroxytryptamine; Serotonin) is the neurotransmitter with the highest number of known receptors in humans, and the importance of 5-HT is also reflected in the number of species using 5-HT as a signalling molecule and the number of 5-HT receptors found within each species. 15 human 5-HT receptors have at this date been characterised and classified into seven 5-HT receptor families. Six of ...
    • Homology Modeling of Human <gamma>-Butyric Acid Transporters and the Binding of Pro-drugs 5-Aminolevulinic Acid and Methyl Aminolevulinic Acid used in Photodynamic Therapy 

      Baglo, Yan; Gabrielsen, Mari; Sylte, Ingebrigt; Gederaas, Odrun Arna (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Photodynamic therapy (PDT) is a safe and effective method currently used in the treatment of skin cancer. In ALA-based PDT, 5-aminolevulinic acid (ALA), or ALA esters, are used as pro-drugs to induce the formation of the potent photosensitizer protoporphyrin IX (PpIX). Activation of PpIX by light causes the formation of reactive oxygen species (ROS) and toxic responses. Studies have indicated that ...
    • In Silico Methods for the Discovery of Orthosteric GABAB Receptor Compounds 

      Evenseth, Linn; Warszycki, Dawid; Bojarski, Andrzej J; Gabrielsen, Mari; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-07)
      The GABA<sub>B</sub> receptor (GABA<sub>B</sub>-R) is a heterodimeric class C G protein-coupled receptor comprised of the GABA<sub>B1a/b</sub> and GABA<sub>B2</sub> subunits. The endogenous orthosteric agonist γ-amino-butyric acid (GABA) binds within the extracellular Venus flytrap (VFT) domain of the GABA<sub>B1a/b</sub> subunit. The receptor is associated with numerous neurological and ...
    • Ligand-guided homology modelling of the GABAb2 subunit of the GABAb receptor 

      Freyd, Thibaud; Warszycki, Dawid; Mordalski, Stefan; Bojarski, Andrzej J; Sylte, Ingebrigt; Gabrielsen, Mari (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-21)
      γ-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the central nervous system, and disturbances in the GABAergic system have been implicated in numerous neurological and neuropsychiatric diseases. The GABA<sub>B</sub> receptor is a heterodimeric class C G protein-coupled receptor (GPCR) consisting of GABA<sub>B1a/b</sub> and GABA<sub>B2</sub> subunits. Two GABA<sub>B</sub> receptor ...
    • Structure, function and inhibition of the serotonin transporter studied by molecular docking, -dynamics and virtual screening 

      Gabrielsen, Mari (Doctoral thesis; Doktorgradsavhandling, 2011-09-16)
      Den tre-dimensjonale (3D) strukturen til serotonin-transporteren er ukjent og arbeidet som beskrives i avhandlingen er basert på teoretiske 3D-modeller av transporteren. Modellene har blitt brukt til å simulere bevegelsene i transporterstrukturen som skjer når serotonin transporteres samt til å studere hvordan forbindelser som blokkerer transporten binder til transporteren. For å gjøre det sistnevnte ...
    • Synthesis, in vitro and in vivo biological evaluation of new oxysterols as modulators of the liver X receptors 

      Åstrand, Ove Alexander Høgmoen; Viktorsson, Elvar Örn; Kristensen, Aleksander Lim; Ekeberg, Dag; Røberg-Larsen, Hanne; Wilson, Steven Ray Haakon; Gabrielsen, Mari; Sylte, Ingebrigt; Rustan, Arild; Thoresen, G. Hege; Rongved, Pål; Kase, Eili Tranheim (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-26)
      Liver X Receptor (LXR) modulators have shown potential as drugs since they target genes affecting metabolism and fatty acid synthesis. LXR antagonists are of particular interest since they are able to reduce the synthesis of complex fatty acids and glucose uptake. Based on molecular modeling, five new cholesterol mimics were synthesized, where four contained a hydroxyl group in the 22-S-position. ...
