1. Drug Analysis : Bioanalytical Method Development and Validation
Sammanfattning : This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries. Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography. LÄS MER
2. Antidepressant drug effects in vivo: Focus on pharmacokinetic and pharmacodynamic responses in different experimental paradigms
Sammanfattning : Pharmacokinetic and pharmacodynamic activities of the antidepressants venlafaxine (VEN) and citalopram (CIT) were investigated in the portacaval shunted (PCS) rat, a model of chronic hepatic encephalopathy (HE), and normal/control rats. The levels of VEN in serum and brain were higher in PCS rats than in controls after a single injection and chronic treatment with VEN (10 mg/kg). LÄS MER
3. Pharmacokinetics of the enantiomers of thalidomide
Sammanfattning : Thalidomide has a chiral center and the racemate of (+)-(R) and (-)-(S)-thalidomide was introduced as a hypnotic/sedative drug in 1957. In 1961 it was withdrawn due to teratogenicity and neuropathy. There is a growing interest in thalidomide treatment of immunomodulatory diseases. LÄS MER
4. Structural studies of drug targets and a drug metabolizing enzyme
Sammanfattning : The work presented in this thesis describes how structural information about a protein can be acquired, and how it can be used to answer scientific questions about proteins’ function, their dynamic behaviour and their interactions with other proteins or ligands.The catalytic function of the pyrimidine-degrading, drug metabolizing enzyme β-ureidopropionase (βUP) is dependent on the shift between oligomeric states.

5. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes
Sammanfattning : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. LÄS MER
