1. Engineered Yeast as Biocatalyst for Stereoselective reductions of Dicarbonyl Compounds
Sammanfattning : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. LÄS MER
2. Selective Transformations of Allylic Compounds and Enol Derivatives : Synthesis of Fluorinated and Nitrogenated Scaffolds
Sammanfattning : In this thesis, new synthetic methods to give access to molecules having fluorinated scaffolds and other polar functional groups have been developed. The methods give access to highly valuable organic compounds that may serve as building blocks in the synthesis of functionalized drug candidates. LÄS MER
3. Exploring Conjugate Addition Activity in Pseudozyma antarctica Lipase B
Sammanfattning : Multifunctional enzymes have alternative functions or activities, known as “moonlighting” or “promiscuous”, which are often hidden behind a native enzyme activity and therefore only visible under special environmental conditions. In this thesis, the active-site of Pseudozyma (formerly Candida) antarctica lipase B was explored for a promiscuous conjugate addition activity. LÄS MER
4. Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level
Sammanfattning : Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. LÄS MER
5. Substrate specificities and functional properties of human short-chain dehydrogenases / reductases
Sammanfattning : Short-chain dehydrogenases/reductases (SDRs) constitute a universal superfamily of functionally heterogeneous proteins and participate in the metabolism of steroids, prostaglandins, retinoids, aliphatic alcohols, and xenobiotics. So far, more than 3000 members including species variants and over 60 human SDR genes are deposited in databases. LÄS MER
