2. 1. Adsorption of pinosylvin onto the structure of wood : mechanism and adsorption parameters

   Author : Ildiko Mohammedne Ziegler; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Abstract : Pinosylvin and polyhydroxybenzene derivatives are natural components of wood, known for their fungicidal/fungistatic properties. These components were used as adsorbates in the present investigation. READ MORE

4. 2. Reaction mechanism of metalloenzymes studied by theoretical methods

   Author : Geng Dong; Beräkningskemi; []
   Keywords : Metalloenzymes; Reaction mechanism; QM MM; DFT; DMRG; CAS-srDFT; Big-QM; QTCP;

   Abstract : Metalloenzymes catalyse a wide variety of reactions in nature. In the thesis, I have studied the reaction mechanism of three metalloenzymes, viz. READ MORE

5. 3. Structure-Reactivity Correlations for Reactions of Palladium(II) and Platinum(IV) Complexes

   Author : Tiesheng Shi; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; thiol; l-methionine; maleic acid; carboxylic acid; thioether; platinum IV ; palladium II ; linear free energy relationship; volumes of activation; structure-reactivity correlation; reduction; substitution; equilibria; kinetics; mechanism; glutathione; Animal physiology; Djurfysiologi;

   Abstract : The kinetics and mechanism for substitution reactions on tetraaquapalladium(II) by an extended series of thioethers, a great number of carboxylic acids, and olefins have been studied by use of UV-VIS, stopped-flow, and high-pressure stopped-flow spectrophotometry and NMR spectroscopy. Second-order rate constants k and activation parameters (activation enthalpies, entropies, and volumes) for formation of monodentate 1:1 complexes have been determined. READ MORE

6. 4. Glutaredoxins : structure, function and mechanism

   Author : Fredrik Åslund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Thioredoxin (Trx) and glutaredoxin (Grx) are small (9-12 kDa) intracellular disulfide reducing enzymes. They were originally described as hydrogen donors for ribonucleotide reductase (RR), the enzyme that catalyzes the conversion of ribonucleotides to deoxyribonucleotides. READ MORE

7. 5. Interactions of Anticancer Active Platinum(II) Complexes with DNA

   Author : Johan Kjellström; Bröstcancer-genetik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; polyelectrolyte; medium effects; salt dependence; DSC; CD; HPLC; oligonucleotide; hairpin; DNA; anticancer active platinum II compounds; kinetics; mechanism; Oorganisk kemi; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Abstract : The kinetics and mechanism for interactions of the anticancer active platinum(II) complexes cis-[PtCl2(NH3)2)], cis-[PtCl2(NH3)(c-C6H11NH2)], and trans-[PtCl2-(NH3)(quinoline)] with DNA have been studied using a combination of HPLC, circular dichroism (CD), UV/vis spectroscopy, and differential scanning calorimetry (DSC). Reactions of the monoaqua forms (charge = +1) of these complexes with single-stranded DNA oligonucleotides, typically between 13-17 bases long, were found to depend on i) the composition of the reaction medium, ii) the exact nature and location of the platination target, and iii) on the DNA structure.
