    Abstract : In chronic inflammatory diseases like asthma or rheumatoid arthritis, erroneous and exaggerated accumulation of leukocytes in a tissue inadvertently causes the body harm. Several efficient anti-inflammatory drugs exist, for example corticosteroids and cyclo-oxygenase inhibitors. READ MORE

    Abstract : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. READ MORE

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

    University dissertation from Inorganic Chemistry, Chemical Center, Lund University

    Author : Johan Kjellström; Lund University.; Lunds universitet.; [2001]
    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.
