1. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties
Sammanfattning : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. LÄS MER
2. Design, Synthesis and Thermodynamic Studies of Galectin Ligands
Sammanfattning : The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. LÄS MER
3. Synthesis of Indole Alkaloids and Development of New Methodology
Sammanfattning : This thesis describes our efforts towards the total synthesis of natural products and the development of a newmethodology to afford a synthetically important scaffold.Chapter 2 outlines our efforts towards the total synthesis of a marine natural product, perophoramidine as wellas our completed synthesis of dehaloperophoramidine.

4. Synthesis of Spiro-bicyclo[2.2.2]Octane Derivatives Towards the Development of Paclitaxel Mimetics
Sammanfattning : Many of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). LÄS MER
5. On-line Sample Pretreatment Based on Membrane Enrichment, Mainly Using Supported Liquid Membranes, for Chromatographic Analysis
Sammanfattning : The main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. LÄS MER
