  1. 1. Terpenoid Plant Metabolites - Structural Characterization and Biological Importance

    Författare :Eliana Maldonado; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terpenoid Sesquiterpene lactones Breast-cancer cell lines Cytotoxicity Antileishmanicial Structural characterization;

    Sammanfattning : In response to the challenges of their local environments, organisms produce of a large number of chemical diverse compounds with complex stereochemistry and reactive functional groups. These characteristics enable them to interact and bind specifically to biological target molecules and exert various biological activities, and have assured that Natural products continues to be an important source of bioactive compounds, which, for example, facilitate the search for new lead structures that can be developed into new pharmaceuticals.

    Sammanfattning : The spectacular biodiversity of our planet is the result of millions of years of evolution. Over this time animals and plants have evolved and adapted to different environments, developing specific behavioral and physical adaptations to increase their chances of survival. LÄS MER

  3. 3. Functional and structural characterization of the human mitochondrial helicase

    Författare :Jenny Korhonen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Mitochondria; mtDNA; replication; replisome; TWINKLE; mtSSB; POL g ; adPEO.;

    Sammanfattning : Mitochondria are the energy producing organelles of the eukaryotic cell. The human mitochondrial DNA (mtDNA) is a double stranded circular molecule of about 16 kb, usually present at 1000-10 000 copies per cell. The genome encodes 13 polypeptides involved in respiration, two ribosomal RNA s and a set of 22 transfer RNA s. LÄS MER

  4. 4. Drug Metabolites Formed by Cunninghamella Fungi : Mass Spectrometric Characterization and Production for use in Doping Control

    Författare :Axel Rydevik; Mikael Hedeland; Ulf Bondesson; David Cowan; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cunninghamella blakesleeana; Cunninghamella elegans; Doping Control; Drug Metabolites; Glucuronide Production; Mass Spectrometry; Reactive Metabolites; Reference Material; Structural Characterization; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : This thesis describes the in vitro production of drug metabolites using fungi of the Cunninghamella species. The metabolites were characterized with mainly liquid chromatography-mass spectrometry using ion-trap and quadrupole-time-of-flight instruments. A fungal in vitro model has several advantages e.g. LÄS MER
