  1. 6. Galanin receptor ligands : Design, synthesis, characterization and biological effects

    Författare :Kristin Webling; Ülo Langel; Tore Bengtsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Galanin is a 29/30 amino acid long bioactive peptide discovered over 30 years ago when C-terminally amidated peptides were isolated from porcine intestines. The name galanin originates from a combination of the first and last amino acids - G from glycine and the rest from alanine. LÄS MER

  3. 7. Studies of a Proteinase-activated Cell Surface Receptor

    Författare :Sverker Nystedt; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; receptor; proteinase; PAR-2; molecular cloning; in situ hybridisation; Expression; G-protein; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The G protein-coupled receptors form one of the largest families of proteins involved in signalling between cells. It contains receptors for molecules as diverse as biogenic amines, glycoproteins and enzymes. The manuscripts included in this thesis together describe the initial characterisation of a previously unknown receptor of this class. LÄS MER

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

    Författare :Christian Sköld; Anders Karlén; Anders Hallberg; Torbjörn Lundstedt; Tommy Liljefors; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; Angiotensin II; AT1; AT2; SAR; bioactive conformation; turn mimetic; peptidomimetic; DISCO; homology model; 3D-QSAR; CoMFA; Farmaceutisk kemi;

    Sammanfattning : 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. 9. The opioid peptide dynorphin A : Biophysical studies of peptide–receptor and peptide–membrane interactions

    Författare :Johannes Björnerås; Lena Mäler; Astrid Gräslund; Scott Prosser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynorphin A; opioid receptor; neuropeptide; bicelles; NMR; diffusion; decomposition; Biophysics; biofysik;

    Sammanfattning : The work presented in this thesis concerns the opioid peptide dynorphin A (DynA). DynA functions primarily as a neurotransmitter and belongs to the family of typical opioid peptides. These peptides are a part of the opioid system, together with the opioid receptors, a family of GPCR membrane proteins. LÄS MER

  7. 10. Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours

    Författare :Christina Swärd; Göteborgs universitet; []
    Nyckelord :Carcinoid; Endocrine pancreatic tumour; Neuroendocrine; Octreotide; Somatostatin receptor; Peptide receptor; Radionuclide therapy; Absorbed dose; Chromogranin A; Liver transplantation;

    Sammanfattning : Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours Background. Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) originate from endocrine cells of the intestinal mucosa and pancreas. LÄS MER
