1. On the separation of enantiomers by direct crystallization
Sammanfattning : .... LÄS MER
2. Synthesis of Polyhydroxylated Surfactants : Comparison of Surfactant Stereoisomers and Investigation of Haemolytic Activity
Sammanfattning : I den här avhandlingen har vi studerat hur man kan göra nya tensider. En tensid är en speciell molekyl som har förmågan att lösa sig i både vatten och olja. Man kan göra följande experiment hemma: Fyll en glasburk till hälften med vatten och tillsätt en droppe matolja. LÄS MER
3. Synthesis and structure activity relationship studies of non-nucleoside HIV-1 reverse transcriptase inhibitors
Sammanfattning : HIV-1 reverse transcriptase (RT) is a target for anti-HIV chemotherapy. A series of PETT PhenylEthylThiazoleThiourea) non-nucleoside HIV-1 RT inhibitors were synthesised. All compounds were tested in an HIV-1 RT enzyme assay, and in cell culture using MT-4 cells and wild-type virus. LÄS MER
4. Forensic Toxicological Aspects of Tramadol : Focus on Enantioselective Drug Disposition and Pharmacogenetics
Sammanfattning : One of the most difficult parts in forensic toxicology is to interpret obtained drug concentrations. Was it therapeutic, toxic or even lethal to the particular individual that the blood sample was drawn from? Concentrations of opioid drugs are especially difficult to interpret, because of large interindividual differences in innate and acquired tolerance. LÄS MER
5. Lipase catalysed reactions of terpenoids : formation of hemiacetal esters : resolution of cryptone and its transformation to cadinenes
Sammanfattning : During attempted enzyme-catalysed resolution of sterically hindered secondary alcohols, hemiacetals and their esters were unexpectedly detected. Hemiacetal esters are reactive compounds that decompose to alcohol, aldehyde and acid under ordinary work-up conditions i.e. in contact with water, acid, or silica gel. LÄS MER
