  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

  5. 4. 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.

  7. 5. Light Control using Organometallic Chromophores

    Författare :Johan Henriksson; Patrick Norman; Olav Vahtras; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organometallic chromophores; two-photon absorption; excited state absorption; excited state dipole moment; four-component formalism; clamping levels; spin-transition; Computational physics; Beräkningsfysik;

    Sammanfattning : The interaction between light and organometallic chromophores has been investigated theoretically in a strive for fast optical filters. The main emphasis is on two-photon absorption and excited state absorption as illustrated in the Jablonski diagram. We stress the need for relativistic calculations and have developed methods to address this issue. LÄS MER
