    Sammanfattning : This study addresses the issue of how to convert peptides into drug-like non- peptides with retained biological activities at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. LÄS MER

  3. 2. Possibilities to Utilize Species from the Mozambican Forest Biomass for the Production of Essential Oils : Study of Eucalyptus and Pinus Species and Application of Citronellal as Raw Material for Flavour Chemistry

    Författare :Felisberto P. Pagula; KTH; []
    Nyckelord :Eucalyptus species; essential oil composition; citronellal; hydroxycitronellal;

    Sammanfattning : This thesis deals partly with the isolation and chemicalanalysis of essential oils from selected Eucalyptus and Pinusspecies grown in Mozambique, and partly with the synthesis ofmore valuable compounds from citronellal isolated fromEucalyptus citriodora Hook oil.More than 60 constituents in the volatile oils wereidentified by gas chromatography and gas chromatography-massspectrometry by comparison with authentic substances andliterature data.

  4. 3. Toward Biomass-Derived Recyclable Polyesters

    Författare :Smita Vamdev Mankar; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyester; polycondensation; spiroacetal; chemical recycling; enzymatic degradation;

    Sammanfattning : Fossil-based plastics have become a matter of concern due to their negative environmental impacts such as greenhouse gas emissions and threats to the health of living beings. Alternative polymers derived from sustainable biomass resources have thus become an attractive research field since the last decade. LÄS MER

  5. 4. The gamma-tubulin meshwork as a therapeutic target

    Författare :Lisa Lindström; Malmö Molekylär patologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gamma-tubulin; retinoblastoma; nuclear formation; meshwork; mitochondria; homeostasis;

    Sammanfattning : Cancer is a heterogeneous disease and treatment regime is dependent on type and location of the tumor. Several of the commonly used chemotherapeutics target the functions of the microtubules. One of the major problems with these drugs is the adverse effects associated with their use. LÄS MER
