1. Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships
Sammanfattning : Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to be reactive enough to bind to proteins and form immunogenic complexes that are recognised as foreign.

2. Physico-chemical characteristics and quantitative structure-activity relationships of PCBs
Sammanfattning : The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. LÄS MER
3. Cyclic sulfamides as HIV-1 protease inhibitors : Synthesis, X-ray structure analysis and structure-activity relationship
Sammanfattning : Human Immunodeficiency Virus (HIV) is the causative agent of Acquired Immune Deficiency Syndrome (AIDS). Inhibition of HIV-1 protease leads to immature and non-infectious viral particles. The synthesis of a number of cyclic HIV-1 protease inhibitors and the subsequent evaluation in an enzyme assay is presented in this thesis. LÄS MER
4. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular
Sammanfattning : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. LÄS MER
5. SAR studies of Capsazepinoid Bronchodilators The B-ring and the C-region
Sammanfattning : Capsazepine and similar compounds, capsazepinoids, were shown to be general inhibitors of agonist (leukotriene D4, histamine, acetylcholine, prostaglandin D2) evoked constriction of human small airway preparations. The mechanism of action remains to be elucidated, but established bronchodilator principles, e.g. LÄS MER
