  1. 1. Advances in Ligand Binding Predictions using Molecular Dynamics Simulations

    University dissertation from Uppsala : Uppsala universitet

    Author : Henrik Keränen; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; free-energy perturbation; molecular dynamics; ligand binding; free-energy perturbation; linear interaction energy; binding free-energy; homology modeling; virtual screening; alanine scanning; amino acid mutagenesis; hERG; GPCR; adenosine receptor; serotonin receptor; BRICHOS; cruzain;

    Abstract : Biochemical processes all involve associations and dissociations of chemical entities. Understanding these is of substantial importance for many modern pharmaceutical applications. In this thesis, longstanding problems with regard to ligand binding are treated with computational methods, applied to proteins of key pharmaceutical importance. READ MORE

  2. 2. Evolution of Vertebrate Endocrine and Neuronal Gene Families Focus on Pituitary and Retina

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Ocampo Daza; Uppsala universitet.; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phylogenetics; evolution; molecular evolution; gene family evolution; genome duplication; gene duplication; oxytocin receptor; vasopressin receptor; visual opsin; transducin; growth hormone; prolactin; somatolactin; growth hormone receptor; prolactin receptor; somatostatin receptor; SSTR; IGFBP; evolution; molekylär evolution; fylogeni;

    Abstract : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. READ MORE

  3. 3. Studies of the Neuropeptide Y Receptor Y2 in Human and Zebrafish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helena Fällmar; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y2-receptor; NPY; PYY; G-protein-coupled receptor; mutagenesis; receptor binding; zebrafish; evolution; MEDICINE Physiology and pharmacology Pharmacological research Pharmacology; MEDICIN Fysiologi och farmakologi Farmakologisk forskning Farmakologi; Farmakologi; Pharmacology;

    Abstract : The G-protein coupled receptors (GPCRs) comprise the largest family of receptors in humans and other vertebrates. They are embedded in the cell membrane and are activated by many different signaling molecules. Activation modulates cellular signal transduction pathways and influences many physiological processes.

  4. 4. Computational Modeling of the AT2 Receptor and AT2 Receptor Ligands Investigating Ligand Binding, Structure–Activity Relationships, and Receptor-Bound Models

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christian Sköld; Uppsala universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Angiotensin II; AT1; AT2; SAR; bioactive conformation; turn mimetic; peptidomimetic; DISCO; homology model; 3D-QSAR; CoMFA; Farmaceutisk kemi;

    Abstract : Rational conversion of biologically active peptides to nonpeptide compounds with retained activity is an appealing approach in drug development. One important objective of the work presented in this thesis was to use computational modeling to aid in such a conversion of the peptide angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe).

  5. 5. Neurosteroids Induce Allosteric Effects on the NMDA Receptor Nanomolar Concentrations of Neurosteroids Exert Non-Genomic Effects on the NMDA Receptor Complex

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tobias Johansson; Uppsala universitet.; [2008]
    Keywords : Pharmaceutical pharmacology; Pharmacology; neurosteroids; NMDA receptor; NR2B subunit; ifenprodil; sigma receptor; anabolic androgenic steroids; allosteric modulation; non-genomic; Farmaceutisk farmakologi;

    Abstract : The neurosteroids constitute a group of powerful hormones synthesized and acting in the central nervous system. They participate in a number of important central processes, such as memory and learning, mood and neuroprotection. READ MORE
