  1. 1. Secondary Metabolites from Mozambican Plants

    Författare :Julião Monjane; Centrum för analys och syntes; []
    Nyckelord :Secondary metabolites; Mozambique; Medicinal plants; Isolation; Structural elucidation; Antileishmanial activity;

    Sammanfattning : Products derived from different natural sources have been used for thousands of years by human beings for their everyday needs. Out of these natural sources, plants were the most affordable. Plant-derived products were used for shelter, food, and as medicines. LÄS MER

  3. 2. Systems Biology of the Secondary Metabolism in Filamentous Fungi

    Författare :Jens Christian Froslev Nielsen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genomics; systems biology; secondary metabolites; antibiotics; Next-generation sequencing; secondary metabolism; filamentous fungi; cell factories; Penicillium;

    Sammanfattning : Filamentous fungi constitute a rich reservoir of pharmaceutically relevant bioactive small molecules. These compounds, commonly referred to as secondary metabolites, are widely used as antibiotics for the treatment of microbial infections, but also as other pharmaceuticals such as immunosuppressors, cholesterol lowering agents and anticancer drugs.

  4. 3. Analysis of Secondary Metabolites from Aspergillus fumigatus and Penicillium nalgiovense : Antimicrobial Compounds from Filamentous Fungi Isolated from Extreme Environments

    Författare :Stefan Svahn; Lars Bohlin; Björn Olsen; Ulf Göransson; Erja Chryssanthou; Douglas Kinghorn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aspergillus fumigatus; Penicillium nalgiovense; secondary metabolites; invasive aspergillosis; elicitation; gliotoxin; bis methyl gliotoxin; amphotericin B; Pharmacognosy; Farmakognosi;

    Sammanfattning : This thesis describes the cultivation and extraction of filamentous fungi isolated from extreme environments in the search for new antibiotic compounds. Filamentous fungi are a rich source of medicines including antibiotics, and it is believed that many currently unknown fungal species and bioactive fungal metabolites remain to be discovered.

  5. 4. BIOACTIVE SECONDARY METABOLITES -Isolation Characterization and Synthesis

    Författare :Carola Valdivia; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; Baccharis genistelloides; Piper heterophyllum; Myrtus Communis; Coprinus heptemerus; Thapsia garganica; Piper longestylosum; Piper obliquum; Natural Products;

    Sammanfattning : Nature produces biologically active and chemically intriguing secondary metabolites. To isolate and characterize compounds of novel activity and structure, bioassay-guided fractionations were applied to several plants as well as to a basidiomycete. LÄS MER

  7. 5. Characterization of Secondary Metabolites from Natural Sources

    Författare :Gilda Erosa; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bourreria pulchra; Heliotropium angiospermum; medicinal plants; Cylindrocarpon; Ripartites metrodii; natural products; Ripartites tricholoma; Sideroxylon foetidissimum.;

    Sammanfattning : Natural products have contributed for many years to the development of new medicines for the treatment of diseases. Their structural diversity and complexity have inspired chemists to produce interesting compounds with pharmaceutical use. LÄS MER
