    • Homology Modeling of Transporter Proteins 

      Sylte, Ingebrigt; Gabrielsen, Mari; Kristiansen, kurt (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-24)
      Membrane transporter proteins are divided into channels/pores and carriers and constitute protein families of physiological and pharmacological importance. Several presently used therapeutic compounds elucidate their effects by targeting membrane transporter proteins, including anti-arrhythmic, anesthetic, antidepressant, anxiolytic and diuretic drugs. The lack of three-dimensional structures of ...

    • Homology modeling to screen for potential binding of contaminants to thyroid hormone receptor and transthyretin in glaucous gull (Larus hyperboreus) and herring gull (Larus argentatus) 

      Mortensen, Åse-Karen; Mæhre, Silje; Kristiansen, kurt; Heimstad, Eldbjørg Sofie; Gabrielsen, Geir W.; Jenssen, Bjørn Munro; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-11)
      Thyroid hormone disrupting chemicals (THDCs) are of major concern in ecotoxicology. With the increased number of emerging chemicals on the market there is a need to screen for potential THDCs in a cost-efficient way, and <i>in silico</i> modeling is an alternative to address this issue. In this study homology modeling and docking was used to screen a list of 626 compounds for potential thyroid hormone ...

    • Identification of novel serotonin transporter compounds by virtual Screening 

      Gabrielsen, Mari; Kurczab, Rafal; Siwek, Agata; Wolak, Malgorzata; Ravna, Aina Westrheim; Kristiansen, kurt; Kufareva, Irina; Abagyan, Ruben; Nowak, Gabriel; Chilmonczyk, Zdzislaw; Sylte, Ingebrigt; Bojarski, Andrzej J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-02-12)
      The serotonin (5-hydroxytryptamine, 5-HT) transporter (SERT) plays an essential role in the termination of serotonergic neurotransmission by removing 5-HT from the synaptic cleft into the presynaptic neuron. It is also of pharmacological importance being targeted by antidepressants and psychostimulant drugs. Here, five commercial databases containing approximately 3.24 million drug-like compounds ...

    • A linear combination of pharmacophore hypotheses as a new tool in search or new active compounds - An application for 5-HT1a receptor ligands 

      Warszycki, Dawid; Mordalski, Stefan; Kristiansen, kurt; Kafel, Rafal; Sylte, Ingebrigt; Chilmonczyk, Zdzislaw; Bojarski, Andrzej J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      This study explores a new approach to pharmacophore screening involving the use of an optimized linear combination of models instead of a single hypothesis. The implementation and evaluation of the developed methodology are performed for a complete known chemical space of 5-HT1AR ligands (3616 active compounds with Ki < 100 nM) acquired from the ChEMBL database. Clusters generated from three different ...

    • Substrate binding and translocation of the serotonin transporter studied by docking and molecular dynamics simulations 

      Gabrielsen, Mari; Ravna, aina westrheim; Kristiansen, kurt; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-06-14)
      The serotonin (5-HT) transporter (SERT) plays an important role in the termination of 5-HT-mediated neurotransmission by transporting 5-HT away from the synaptic cleft and into the presynaptic neuron. In addition, SERT is the main target for antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs). The three-dimensional (3D) structure of SERT has not yet been determined, ...
