  1. 6. Combinatorial Methodology. Screening for affinity specific ligands to biological and artificial receptors

    Författare :Margareta Krook; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptide library; combinatorial; screening; phage display; affinity; DNA-interaction; chymotrypsin; peptide inhibitor; antibody; IgG; Fc; molecular imprinting; steroid; receptor; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik;

    Sammanfattning : Combinatorial screening methodology has been employed to select new affinity specific ligands to bilogical and artificial receptors. The screening methodology, in particular screening of combinatorial phage display peptide libraries against target molecules differing in function and shape, is focused upon. LÄS MER

  2. 7. LL-37-derived cyclic antimicrobial drug leads : Design, synthesis, activity and different ways of creating them 

    Författare :Taj Muhammad; Ulf Göransson; Sunithi Gunasekera; Adam A. Strömstedt; Wang Guangshun; Uppsala universitet; []
    Nyckelord :antimicrobial peptide; host defense; antimicrobial; LL-37; KR-12; peptide cyclisation; peptide dimerisation; croos-linking; cyanobactin-macrocyclase; PatGmac; butelase 1; enzymatic cyclisation; immobilisation; Farmakognosi; Pharmacognosy;

    Sammanfattning : In an era where last-line antibiotics are failing, one of the powerful approaches to develop novel therapeutic agents is to turn back to nature in order to identify possible drug candidates. Among the potential candidates, antimicrobial peptides (AMPs) have garnered much attention as an antimicrobial. LÄS MER

  3. 8. Computer simulations of electronic energy transfer and a molecular dynamics study of a decapeptide

    Författare :Maria Lindberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic energy transfer; Monte Carlo simulations; two-particle model; GAF-theory; anisotropic systems; fluorescence depolarization ratios; Brownian Dynamics; rotating donors; Molecular Dynamics; peptide; renin inhibitor;

    Sammanfattning : Electronic energy transfer has been investigated in pure donor systems by means of computer simulations. Calculated properties were the probability that the initially excited donor is excited at a time t after the excitation, Gs(t), the mean square displacement of the excitation and different fluorescence observables.

  4. 9. Cyclic peptides as biological tools : Applications for diagnosis and therapeutics in rheumatoid arthritis and COVID-19

    Författare :Camilla Eriksson; Ulf Göransson; Sunithi Gunasekera; Christian Becker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scaffold peptides; peptide grafting; rheumatoid arthritis; SARS-CoV-2; autoantibodies; peptide synthesis; pharmacognosy;

    Sammanfattning : The overall aims of the projects included in this thesis were to design, synthesize and evaluate cyclic peptide scaffolds grafted with biological epitopes for their ability to bind antibodies in rheumatoid arthritis and COVID-19 sera. One of the main outcomes of this thesis was the observation that scaffold peptides grafted with target epitopes efficiently neutralized anti-citrullinated protein autoantibodies (ACPA) from rheumatoid arthritis patients.

  5. 10. Plasminogen activator inhibitor type-1 : structure-function studies and its use as a reference for intramolecular distance measurements

    Författare :Peter Hägglöf; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; PAI-1 serpin RCL complex formation DDEM Intramolecular distance; Biomedicin; Microbiology; Mikrobiologi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Inhibitors belonging to the serpin (serine protease inhibitor) family control proteases involved in various physiological processes. All serpins have a common tertiary structure based on the dominant b-sheet A, but they have different inhibitory specificity. LÄS MER
