1. 1. Introducing weak affinity chromatography to drug discovery with focus on fragment screening

   Författare :Minh-Dao Duong-Thi; Sten Ohlson; Brian Dymock; Linnéuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; affinity LC-MS; fragment-based drug discovery; fragment screening; high throughput; mass spectrometry; stereoisomer; enantiomer; thrombin; weak affinity chromatography; WAC; WAC-MS.; Biomedical Sciences; Biomedicinsk vetenskap; Biokemi; Biochemistry;

   Sammanfattning : Fragment-based drug discovery is an emerging process that has gained popularity in recent years. The process starts from small molecules called fragments. One major step in fragment-based drug discovery is fragment screening, which is a strategy to screen libraries of small molecules to find hits. LÄS MER

3. 2. New fractionation tools targeting elusive post-translational modifications

   Författare :Celina Wierzbicka; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular imprinting; Molecular recognition; Phosphopeptides; Proteomics; Phosphotyrosine; Phosphohistidine;

   Sammanfattning : Protein phosphorylation is a reversible post-translational modification (PTM)playing a central role in numerous biological events including disease pathogenesis.Thus, the analysis of phosphoproteome is crucial for understandingcellular regulation processes and can facilitate the development of new diagnosticand therapeutic tools.

4. 3. Metabolism of some polychlorinated biphenyl and polybrominated diphenyl ether congeners in the rat

   Författare :Anna Sandholm; Bert-Ove Lund; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Sammanfattning : For the understanding of the metabolic fate of xenobiotics, in vivo studies are needed. In this thesis the metabolism of CB-28 and CB-77 and BDE-209 in the rat are determined. In addition, pharmacokinetic studies of CB-28 and BDE- 209 are included. The compounds were radiolabelled and their excretion and tissue distribution determined. LÄS MER

5. 4. Studies on O-glycosylation of mucin-type proteins and their binding to antibodies, bacterial toxins and viral receptors

   Författare :Stefan Gaunitz; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Carbohydrates are ubiquitous on the surface of all cells in mammals where they are involved in interactions with the surroundings (extracellular matrix), other cells (including self and non-self) and microbes (bacteria and virus). Carbohydrate-protein interactions in nature are often mediated via multivalent binding where the combined strength of multiple receptor- ligand interactions results in a binding that is highly specific and strong.

7. 5. Piperaquine and Metabolites - Bioanalysis and Pharmacokinetics

   Författare :Mohd Yusmaidie Aziz; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioanalysis; Pharmacokinetics; Piperaquine; Malaria;

   Sammanfattning : Antimalarial piperaquine (PQ) is currently used as a partner drug with dihydroartemisinin (DHA), exhibiting high cure rates (>95%) for P. falciparum. Despite its raising usage worldwide with DHA, PQ is synthetically developed outside of big pharma pipelines. LÄS MER
