  1. 11. Experimental Designs at the Crossroads of Drug Discovery

    Författare :Ing-Marie Olsson; Svante Wold; Johan Gottfries; Michael Sjöström; Bo Nordén; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; Design of experiments; Experimental design; Multivariate data-analysis; D-optimal design; 96-well technology; Drug discovery; Assay optimisation; QSAR; Organic chemistry; Organisk kemi;

    Sammanfattning : New techniques and approaches for organic synthesis, purification and biological testing are enabling pharmaceutical industries to produce and test increasing numbers of compounds every year. Surprisingly, this has not led to more new drugs reaching the market, prompting two questions – why is there not a better correlation between their efforts and output, and can it be improved? One possible way to make the drug discovery process more efficient is to ensure, at an early stage, that the tested compounds are diverse, representative and of high quality. LÄS MER

  2. 12. Mistletoes and Thionins : as Selection Models in Natural Products Drug Discovery

    Författare :Sonny Larsson; Anders Backlund; Lars Bohlin; Peter J. Houghton; Uppsala universitet; []
    Nyckelord :Pharmacognosy; drug discovery; mistletoe; phylogeny; cytotoxic peptides; Santalales; Farmakognosi;

    Sammanfattning : The process of drug discovery from natural products starts with the selection of study object. In this project recent knowledge and methods are incorporated to investigate the process of such selection for pharmacognostic investigations. LÄS MER

  3. 13. Modeling the Interaction Space of Biological Macromolecules: A Proteochemometric Approach : Applications for Drug Discovery and Development

    Författare :Aleksejs Kontijevskis; Jarl Wikberg; Jan Komorowski; Robert Glen; Uppsala universitet; []
    Nyckelord :Bioinformatics; proteochemometrics; bioinformatics; chemoinformatics; chemical space; QSAR; retroviral proteases; HIV-1; drug resistance; pharmacogenomics; cytochrome P450; GPCRs; melanocortin receptors; interactome; machine-learning; rough sets; Bioinformatik;

    Sammanfattning : Molecular interactions lie at the heart of myriad biological processes. Knowledge of molecular recognition processes and the ability to model and predict interactions of any biological molecule to any chemical compound are the key for better understanding of cell functions and discovery of more efficacious medicines.

  4. 14. Interaction Characteristics of Viral Protease Targets and Inhibitors : Perspectives for drug discovery and development of model systems

    Författare :Cynthia F Shuman; Jordan J N Tang; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; viral proteases; biomolecular interactions; kinetics; thermodynamics; biosensors; drug discovery; Biokemi; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : Viral proteases are important targets for anti-viral drugs. Discovery of protease inhibitors as anti-viral drugs is aided by an understanding of the interactions between viral protease and inhibitors. This thesis addresses the characterization of protease-inhibitor interactions for application to drug discovery and model system development. LÄS MER

  5. 15. Structural studies of drug targets and a drug metabolizing enzyme

    Författare :Daniela Cederfelt; U. Helena Danielson; Doreen Dobritzsch; Inari Kursula; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biophysics; Protein structure; X-ray crystallography; Cryogenic electron microscopy; Enzymology; Drug discovery; Pyrimidine degradation; Biokemi; Biochemistry;

    Sammanfattning : The work presented in this thesis describes how structural information about a protein can be acquired, and how it can be used to answer scientific questions about proteins’ function, their dynamic behaviour and their interactions with other proteins or ligands.The catalytic function of the pyrimidine-degrading, drug metabolizing enzyme β-ureidopropionase (βUP) is dependent on the shift between oligomeric states.
