1. 1. Cyclooxygenase-2 inhibitors and knee prosthesis surgery

   Författare :Andreas Meunier; Lars Good; Per Aspenberg; Tore Dalén; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-steroidal anti-inflammatory agents; administration dosage; Arthroplasty; knee replacement; Surgical blood loss; Surgery; Cyclooxygenase inhibitors; Cyclooxygenase inhibitors; Fracture healing; Isoxazoles; Postoperative pain; Pyrazoles; Sulfonamides; Surgery; Kirurgi;

   Sammanfattning : Adverse effects of cyclooxygenase (COX) inhibitors on bone healing have previously been demonstrated in diaphyseal fracture models in animals. In spite of that, they are widely used as postoperative analgesics in orthopaedic surgery. After joint replacement, a bone repair process starts at the interface between bone and cement. LÄS MER

3. 2. Design and Synthesis of Inhibitors Targeting the Hepatitis C Virus NS3 Protease : Focus on C-Terminal Acyl Sulfonamides

   Författare :Robert Rönn; Anders Hallberg; Anja Sandström; Federico Corelli; Uppsala universitet; []
   Nyckelord :Pharmaceutical chemistry; hepatitis C virus; HCV; NS3 protease inhibitor; acyl sulfonamide; bioisostere; palladium; carbonylation; microwave; molybdenum hexacarbonyl; Farmaceutisk kemi;

   Sammanfattning : Hepatitis C is a global health problem that affects approximately 120–180 million people. This viral infection causes serious liver diseases and the therapy available suffers from low efficiency and severe side effects. Consequently, there is a huge unmet medical need for new therapeutic agents to combat the hepatitis C virus (HCV). LÄS MER

4. 3. Probing Ligand Binding Mechanisms in Insulin-Regulated Aminopeptidases : Computational analysis and free energy calculations of binding modes

   Författare :Sudarsana Reddy Vanga; Hugo Gutiérrez-de-Terán; Johan Åqvist; Efstratios Stratikos; Uppsala universitet; []
   Nyckelord :Docking; Molecular Dynamics; Binding free energy; Linear Interaction Energy; Free Energy Perturbation; Insulin-Regulated Aminopeptidase; Angiotensin IV; Oxytocin; Vasopressin; HA08; Aryl sulfonamides; HFI compounds.;

   Sammanfattning : In recent years insulin-regulated aminopeptidase (IRAP) has emerged as a new therapeutic target for the treatment of Alzheimer’s disease and other memory-related disorders. So far, many potent and specific IRAP inhibitors had been disclosed, including peptides, peptidomimetics, and low-molecular-weight sulfonamides. LÄS MER

5. 4. Multicomponent Reactions in 11C/12C Chemistry : – Targeting the Angiotensin II Subtype 2 Receptor

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbonylation; positron emission tomography; multicomponent reactions; AT2R; 3; 4-dihydroquinazolinone; sulfonyl azides; Farmaceutisk vetenskap; Pharmaceutical Science;

   Sammanfattning : Section 1 of this thesis contains an introduction to method development in organic synthesis, multicomponent reactions, sulfonyl azides, tracer development in 11C chemistry and the biological target.Section 2 describes the use of sulfonyl azides in carbonylative chemistry. Paper I covers development of a diazotransfer protocol. LÄS MER

7. 5. C2- and C3-symmetric ligands via ring-opening of aziridines

   Författare :Fredrik Lake; KTH; []
   Nyckelord :asymmetric catalysis; aziridine; benzaldehyde; diethylzinc; enantionselective; ligand; proazaphosphatrane; ring-opening; sulfonamide; symmetry; titanium; nicronium;

   Sammanfattning : This thesis deals with the design and synthesis of chiralenantiopure nitrogencontaining ligands and the use of theseligands in asymmetric catalysis. A modular synthetic approachto enantiopure nitrogen-containing ligands was developed. Thesynthetic method is based on the ring-opening of activatedchiral aziridines by nitrogen nucleophiles. LÄS MER
