1. 1. Organometallic complexes with antimalarial properties

   Författare :Lotta Glans; Kemisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioorganometallic chemistry; Chloroquine; Antimalarial; Drug resistance; Organometallic; Arene;

   Sammanfattning : Malaria is a serious disease that causes around 800 000 deaths per year. Current malaria control efforts are hampered by the widespread resistance to common antimalarial drugs, such as the 4-aminoquinoline derivative called chloroquine. LÄS MER

3. 2. BIOACTIVE ORGANOMETALLIC COMPOUNDS

   Författare :Haris Bjelosevic; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological; kinetic; gold; platinum; bioactive; phosphine; ruthenocene; Ferrocene;

   Sammanfattning : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. LÄS MER

4. 3. Quantum Chemical Modelling of Enzymatic and Organometallic Reactions

   Författare :Ferran Planas; Fahmi Himo; Edina Rosta; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; enzyme; organometallic; mechanisms; organisk kemi; Organic Chemistry;

   Sammanfattning : In this thesis, density functional theory (DFT) is employed in the study of two enzymes and two organometallic systems.First, the natural reaction mechanism, as well as the enantioselective formation of α-hydroxyketones catalysed by two thiamine diphosphate (ThDP)- dependent enzymes, namely benzoylformate decarboxylase (BFDC) and 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylic-acid (SEPHCHC)- synthase (MenD), are investigated.

   Sammanfattning : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. LÄS MER

7. 5. Chemistry of Carbon Nanostructures : Functionalization of Carbon Nanotubes and Synthesis of Organometallic Fullerene Derivatives

   Författare :Claes-Henrik Andersson; Helena Grennberg; Nazario Martín León; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotubes; Fullerenes; Purification; Functionalization; Organometallic complexes; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

   Sammanfattning : This thesis is based on two main parts. The first part concerns purification and functionalization of carbon nanotubes (papers I-III), and the second part is related to the synthesis of organometallic fullerene derivatives (papers IV-VII): Two oxidative methods involving aqueous nitric acid were compared with respect to their capability to introduce carboxylic groups into single walled carbon nanotubes, and several literature methods for esterification and amidation of these groups have been evaluated with focus on efficiency and reproducibility in forming covalently functionalized products soluble in organic media.
