  2. 1. Electrochemical Methods for Drug Characterisation and Transdermal Delivery : Capillary Zone Electrophoresis, Conductometry, and Iontophoresis

    Author : Nadia Merclin; Per Hansson; Sven Engström; Arto Urtti; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Capillary zone electrophoresis; precision conductometry; iontophoresis; passive diffusion; lidocaine; ALA; ALA-ester derivatives; sponge phase; carbopol gel; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Abstract : This thesis concerns the development and utilisation of techniques for characterisation and transdermal delivery of various systems for pharmaceutical applications.The degree of dissociation of drug molecules and the mobilities of the different species formed are essential factors affecting the rate of drug delivery by iontophoresis.

  4. 2. Isotopes as Mechanism Spies : Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects

    Author : Susanna MacMillar; Olle Matsson; Anita Hussénius; Daniel M. Quinn; Uppsala universitet; []
    Keywords : Organic chemistry; nucleophilic bimolecular substitution SN2; kinetic isotope effects; precision conductometry; monoamine oxidase B MAO B; reaction mechanism; carbon 11C 14C kinetic isotope effect; ion pairing triple-ion formation; para-substituted benzyl chlorides; tetrabytylammonium cyanide; Organisk kemi;

    Abstract : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

  5. 3. Release and transport of drugs in some complex and interacting systems

    Author : Hans Sjöberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry; fysikalisk och oorganisk farmaceutisk kemi;

    Abstract : Drug formulations come in many forms, some intended for direct and immediate action and others aiming at a controlled manner of drug delivery. Viewed in a more general way drug transport often involves charged units, it takes place in a medium which in many respects must be considered complex - to some degree even reactive. READ MORE
