11. Antimicrobial Peptide Interactions with Phospholipid Membranes : Effects of Peptide and Lipid Composition on Membrane Adsorption and Disruption
Sammanfattning : The interactions between antimicrobial peptides and phospholipid membranes were investigated, in terms of lipid headgroup variations and the role of cholesterol, as well as peptide composition and structure. Also strategies for increasing proteolytic stability were evaluated. LÄS MER
12. Synthesis and structure activity relationships of competitive NMDA antagonists with analgesic activity
Sammanfattning : The compounds cis-3-(1-oxo-2-phosphonoethyl)-2-piperidinecarboxylic acid 1 and cis-3-(1-hydroxy-2-phosphonoethyl)-2-piperidinecarboxylic acid 2 were synthesized and found to be potent N-methyl-D-aspartate (NMDA) antagonists. NMR analysis showed that 1 prefers a 2eq,3ax chair conformation probably due to a conformer-stabilizing internal hydrogen bond. LÄS MER
13. Investigation of the Freeze-Thawing Process for Pharmaceutical Formulations of a Model Protein
Sammanfattning : Recent advances in recombinant DNA technology have resulted in a great number of proteins with a potential to enter pharmaceutical formulations. The most commonly used method for preparing protein pharmaceuticals is by freeze-drying. LÄS MER
14. Electrochemical Methods for Drug Characterisation and Transdermal Delivery : Capillary Zone Electrophoresis, Conductometry, and Iontophoresis
Sammanfattning : 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.

15. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants
Sammanfattning : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. LÄS MER
