  2. 1. Macrocyclic polypeptides from plants

    Author : Ulf Göransson; David Craik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; Farmakognosi;

    Abstract : The aim of this work was to explore the structural and functional diversity of polypeptides that are found in plants. Expanding knowledge of simililarities between plant use of these compound and animal use promises exceptional opportunities for finding, from plant research, new structures with biomedical and biotechnological potential.

  4. 2. Secondary Metabolites from Mozambican Plants

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

    Abstract : 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. READ MORE

  5. 3. Discovery of Secondary Metabolites from Rwandese Medicinal Plants : Isolation, Characterization and Biological Activity

    Author : Daniel Umereweneza; Máté Erdélyi; A Gogoll; Théoneste Muhizi; Yngve Stenstrøm; Uppsala universitet; []
    Keywords : Natural products; Nuclear Magnetic Resonance NMR ; Dihydrochalcones; Iridoids; Silphiperfolanols; Pyrrolizidine alkaloids PAs ; Rwandese Medicinal Plants; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Plants have served as the principal source of medicines in different parts of the world through the ages. Herb-derived medicines have been used as decoctions, infusions, tinctures or single substance drugs. READ MORE

  6. 4. Bioactivity of Medicinal Bolivian Andean plants. Effects on cell proliferation and related processes

    Author : Gloria Rodrigo; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bolivian medicinal plants; colon cancer; cell proliferation; DNA synthesis; apoptosis; caspase-3; sesquiterpene; curcuphenol; damsin; coronopilin;

    Abstract : Colon cancer is common in both developed and developing countries, and is responsible for at least 600,000 deaths globally every year. It is therefore the second most common cause of cancer-related mortality. Extensive studies are being conducted worldwide to find more effective drugs that can be used in cancer treatment. READ MORE

  7. 5. Studies on Cytotoxic and Neutrophil Challenging Polypeptides and Cardiac Glycosides of Plant Origin

    Author : Senia Johansson; Tore Mellstrand; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; cytotoxic; neutrophil; polypeptides; Phoradendron tomentosum; Digitalis purpurea; plant; mistletoe; MS MS; Edman degradation; breast cancer; macrocyclic peptides; multidrug resistance protein; primary structures; phoratoxin; isolation; digitoxin; cardiac lycoside; structure-activity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; farmakognosi;

    Abstract : This thesis examines the isolation and characterisation (biological and chemical) of polypeptides from plants. A fractionation protocol was developed and applied on 100 plant materials with the aim of isolating highly purified polypeptide fractions from small amounts of plant materials. READ MORE
