  2. 1. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation

    Author : Charlotte Johansson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; allylic alkylation; η3-allyl palladium complexes; regioselectivity; PN-ligand; memory effects; dynamics; ligand effect; trans effects.;

    Abstract : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. READ MORE

  4. 2. Infrared spectroscopy : Method development and ligand binding studies

    Author : Saroj Kumar; Andreas Barth; Janos Mink; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared; Ligand binding; method development; Biophysical chemistry; Biofysikalisk kemi; biofysik; Biophysics;

    Abstract : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. READ MORE

  5. 3. Assessment of Computational Methods for Ligand Binding

    Author : Paulius Mikulskis; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; binding affinities; MM GBSA; MM PBSA; LIE; FEP; TI; BAR; protein-ligand complexes; drug design;

    Abstract : Most drugs act on biomacromolecules. The Cost of developing new drugs is very high. A method to accurately predict binding affinities would be very useful. READ MORE

  6. 4. Asymmetric catalysis : ligand design and microwave acceleration

    Author : Ulf Bremberg; KTH; []
    Keywords : ;

    Abstract : This thesis deals partly with the design and synthesis ofligands for use in asymmetric catalysis, and partly with theapplication of microwave heating on metal-based asymmetriccatalytic reactions.Enantiomerically pure pyridyl alcohols and bipyridylalcohols were synthesized from the chiral pool for future usein asymmetric catalysis.

  7. 5. Adenovirus-mediated CD40 Ligand Immunotherapy of Prostate and Bladder Cancer

    Author : Helena Dzojic; Magnus Essand; Thomas H Tötterman; Aristides Eliopoulos; Uppsala universitet; []
    Keywords : Medicine; immunotherapy; gene therapy; prostate cancer; bladder cancer; adenoviral vector; CD40 ligand; promoter; PPT; TSTA; depsipeptide FK228; TRAMP-C2; Medicin;

    Abstract : Cancer immunotherapy aims at reversing the immunosuppressive tumor environment and enhancing anti-tumor immunity. This thesis comprises studies on murine models for prostate (TRAMP-C2) and bladder (MB49) cancer with the aim to explore if the introduction of an adenoviral vector expressing CD40 ligand (AdCD40L) can induce anti-tumor immune responses.
