  1. 6. GALIELLALACTONE ANALOGUES – SYNTHESIS AND PROPERTIES

    Författare :Ritha Gidlöf; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galiellalactone; one-pot peptide coupling and intramolecular Michael addition; tandem palladium-catalyzed carbonylation intramolecular Diels-Alder; STAT3 inhibition;

    Sammanfattning : Cancer cells use normal cell signalling pathways in a proliferative fashion in order to prolong their own survival. Inhibition of one of the major signal proteins, STAT3 (Signal Transducer and Activator of Transcription 3) has previously been shown to induce apoptosis. LÄS MER

  3. 8. Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands

    Författare :Anna Hansson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bis-crown ether analogue; molecular recognition; molecular tubes; Tröger s base; dihalo-analogues;

    Sammanfattning : Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. LÄS MER

  4. 9. Polyamine analogues inhibit neuroblastoma cell growth

    Författare :Erika Söderstjerna; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; survivin; cell cycle; polyamine analogue; polyamines; apoptosis; neuroblastoma; MYCN;

    Sammanfattning : Abstract Neuroblastoma is a highly malignant neoplasm found in children. Although children with high-risk neuroblastoma respond to chemotherapy, relapses are common and an estimated long-time survival prognosis is approximately 15%. Thus, there is a tremendous need for new chemotherapeutic drugs for the treatment for neuroblastoma. LÄS MER

  5. 10. Dissolution of fluorite type surfaces as analogues of spent nuclear fuel : Production of suitable analogues and study the effect of surface orientation on dissolution

    Författare :Jose Godinho; Sandra Piazolo; Tonci Balic-Zunic; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluorite; spent nuclear fuel; crystal structure; CeO2; CaF2; crystal orientation; topography; confocal profilometry; Mineralogy; Mineralvetenskap; Geology; geologi;

    Sammanfattning : It is accepted worldwide that the best final solution for spent nuclear fuel is to bury it in deep geological repositories. Despite the physical and chemical barriers that are supposed to isolate the nuclear waste for at least 100.000 years, some uncertainty factors may cause underground water to get in contact with the nuclear waste.
