  2. 11. Nitrile Hydratases and Epoxide-Transforming Enzymes : Quantum Chemical Modeling of Reaction Mechanisms and Selectivities

    Author : Kathrin Hopmann; Fahmi Himo; Nigel G. Richards; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi;

    Abstract : Quantum chemical studies of enzymatic reactions are able to provide detailed insight into mechanisms and catalytic strategies. The energetic feasibility of proposed mechanisms can be established, and new possible reaction pathways can be put forward. READ MORE

  4. 12. Synthetic Pathways to Aliphatic Polyesters and Scaffold Design

    Author : Therese Tyson; Ann-Christine Albertsson; Elisabetta Ranucci; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Abstract : As the field of tissue engineering progresses, a continuous development of scaffold fabrication techniques and suitable degradable materials is required to obtain scaffolds with tunable characteristics. This thesis has focused on the development of pathways to synthesize degradable aliphatic polyesters and on the design of highly porous scaffolds from this class of materials. READ MORE

  5. 13. Characterization of Substance P (SP) Aminoterminal SP (1-7) Binding in Brain Regions and Spinal Cord of the Male Rat : Studies on the Interaction with Opioid Related Pathways

    Author : Milad Botros; Fred Nyberg; Tsukasa Sakurada; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Biologisk beroendeforskning;

    Abstract : Binding sites for substance P(1-7), SP(1-7) have been identified and characterized for the first time in crude membrane fraction from rat CNS using tritiated ([3H]) SP(1-7) as tracer. These putative receptors were investigated in relation to their affinity for tachykinins, opioid peptides and sigma receptor ligands. READ MORE

  6. 14. Natural Product Synthesis and Development of Novel Reaction Methodology

    Author : Jakob Danielsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perophoramidine; communesin; quaternary stereocenter; Diels-Alder; 1; 2-asymmetric induction; polar Felkin-Anh; Cornforth-Evans; Mukaiyama aldol; 3-dipolar cycloaddition; azomethine ylide; 2-amino alcohol; anti-α-amino-β-hydroxy ester;

    Abstract : This thesis deals with the development of new reaction methodology for stereoselective synthesis, as well as total synthesis of natural products and investigations of the stereochemical outcome in the Mukaiyama aldol reaction. Chapter 2 describes efforts made towards the total synthesis of the oxindole natural products perophoramidine and the communesin. READ MORE

  7. 15. Photocatalytic TiO2 thin films for air cleaning : Effect of facet orientation, chemical functionalization, and reaction conditions

    Author : Bozhidar Stefanov; Lars Österlund; Gunnar Niklasson; Claes-Göran Granqvist; Peter Christian Kjærgaard Vesborg; Uppsala universitet; []
